But planers are very large and massive compared to the shapers. Planers are generally used for machining large work pieces which cannot be held in a shaper. The planers are capable of taking heavier cuts. The planer was first developed in the year 1817 by Richard Roberts, an Englishman.\r\nTypes of planer\r\nThe different types of planer which are most commonly used are:\r\n\r\n \tStandard or double housing planer.\r\n \tOpen side planer.\r\n \tPit planer.Edge or plate planer.\r\n \tDivided or latching table planer.\r\n\r\ntypes of planer machines\r\nStandard or double housing planer\r\nIt is most widely used in work shops. It has a long heavy base on which a table reciprocates on accurate guide ways. It has one draw back. Because of the two housings, one on each side of the bed, it limits the width of the work that can be machined. Fig. 3.30 shows a double housing planer.\r\nOpen side planer\r\nIt has a housing only on one side of the base and the cross rail is suspended from the housing as a cantilever. This feature of the machine allows large and wide jobs to be clamped on the table. As the single housing has to take up the entire load, it is made extra-massive to resist the forces. Only three tool heads are mounted on this machine. The constructional and driving features of the machine are same as that of a double housing planer. Fig. 3.31 shows an open side planer.\r\nPit planer\r\nIt is massive in construction. It differs from an ordinary planer in that the table is stationary and the column carrying the cross rail reciprocates on massive horizontal rails mounted on both sides of the table. This type of planer is suitable for machining a very large work which cannot be accommodated on a standard planer and the design saves much of floor space. The length of the bed required in a pit type planer is little over the length of the table. Fig. 3.32 shows a pit planer.\r\nEdge or plate planer\r\nThe design of a plate or edge planer is totally unlike that of an ordinary planer. It is specially intended for squaring and beveling the edges of steel plates used for different pressure vessels and shipbuilding works. Fig. 3.33 shows an edge planer.\r\nDivided table planer\r\nThis type of planer has two tables on the bed which may be reciprocated separately or together. This type of design saves much of idle time while setting the work. To have a continuous production one of the tables is used for setting up the work and the other is used for machining. This planer is mainly used for machining identical work pieces. The two sections of the table may be coupled together for machining long work. Fig. 3.34 shows a divided table planer.","headline":"Types Of Planer machine &#8211; Classification Of Planer Machine","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-03-29","mainEntityOfPage":"False","dateModified":"February 20, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/03\/types-of-planer-machines-242x300.jpg","height":300,"width":242},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/shaper-tools-types-of-shaper-tools-classification-of-shaper-tools/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/03/shaper-tools-250x300.jpg')"></div><span class="sr-only">link to Shaper tools | Types of Shaper Tools , Classification Of Shaper Tools</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/shaper-tools-types-of-shaper-tools-classification-of-shaper-tools/">Shaper tools | Types of Shaper Tools , Classification Of Shaper Tools</a></p></header><div class="excerpt"><p>Shaper tools | Types of Shaper Tools , Classification Of Shaper Tools

It differs from a lathe tool in tool angles. Shaper tools are much more rigid and heavier to withstand shock experienced by the cutting tool at the commencement of each cutting stroke. In a shaper tool the amount of side clearance angle is only 2 angle is 40 for cast iron and steel. Small clearance angle adds strength.\r\n\r\nAs the tool removes metal mostly from its side cutting edge, side rake of 10 is usually provided with little or no rake. A shaper can also use a right hand or left hand tool. High speed steel is most\u00a0 common material for a shaper tool but shock resistant cemented carbide tipped tool is also used where harder material is to be machined. As in a lathe, tool holders are also used to hold the tool bits.\r\n\r\nTypes of shaper Tools \/\u00a0 Classification of shaper tools\r\n\r\nThe shaper tools are classified as\r\n\r\nAccording to the shape:\r\n\r\n \tStraight tool.\r\n \tCranked tool.\r\n \tGoose necked tool.\r\n\r\nAccording to the direction of cutting:\r\n\r\n \tLeft hand tool.\r\n \tRight hand tool.\r\n\r\nAccording to the finish required:\r\n\r\n \tRoughing tool.\r\n \tFinishing tool.\r\n\r\nAccording to the type of operation\r\n\r\n \tDown cutting tool.\r\n \tParting off tool.\r\n \tSquaring tool.\r\n \tSide recessing tool.\r\n\r\nAccording to the shape of the cutting edge\r\n\r\n \tRound nose tool.\r\n \tSquare nose tool.\r\n\r\n\r\n\r\n\r\nCommonly used shaper tools are shown in Fig.\r\n\r\nRound nose tool: This is used for roughing operations. The tool has no top rake. It has side rake angle, in between 10 to 200. Round tool is of two types used for rough machining of horizontal surface. Round nose tool can be left handed or right handed .\u00a0 Another type of round nose tool which is cranked or bent is used for machining vertical surfaces. It is known as round nose cutting down tool.\r\n\r\nshaper tools\r\n\r\nSquare nose tool: This tool is used for finishing operations. The cutting edge may have different\u00a0 widths. It is also used to machine the bottom surfaces of key ways and grooves.\r\n\r\nSide recessing tool: This is a special tool used for machining T slots and Narrow slots . This\u00a0 tool can be both left handed and right\r\n\r\nParting off tool: \r\n\r\nThis is used for parting off operation. It is also used for cutting narrow slots. It has no side rake angle.

In half reciprocating stroke the tool cuts the metal and in the second half, the tool returns to the original positions. Shaping machine is not a production machine. It is widely used in tool rooms of machine shops.\u00a0\r\n\r\nTo generate reciprocating motion of ram of shaping machine we having two alternatives:\r\n\r\n \tBy using a four-bar mechanism ( Cylinder, Piston, connecting rod, and crank ) driven by the motor. This machine is called a mechanical shaping machine.\r\n \tBy using a hydraulic DA cylinder. This machine is called a hydraulic shaping machine.\r\n\r\nA typical hydraulic drive for horizontal shaper is shown in Fig. A constant speed motor drives a hydraulic pump which delivers oil at a constant pressure to the line. A regulating valve admits oil under pressure to each end on the piston alternately, at the same time allowing oil from the opposite end of the piston to return to the reservoir.\r\nHydraulic shaper machine Diagram\r\n hydraulic shaper Diagram\r\nParts of Hydraulic shaper machine: \r\n\r\n \tFixed Double Acting Cylinder, - Fixed in RAM of Machine\u00a0\r\n \tspool-type DC valve, \r\n \tspool shaft stroke adjusting lever, \r\n \tpump, \r\n \tpressure relief valve, \r\n \treturn line with filter, \r\n \toil reservoir.\r\n\r\nWorking Of Hydraulic operated Shaper machine :\u00a0\u00a0\r\nThe piston is pushed by the oil and, being connected to the ram carrying the tool. The admission of oil to each end of the piston, alternately, is accomplished with the help of trip dogs and pilot valve. As the ram moves and completes its stroke (forward or return) a trip dog will trip the pilot valve which operates the regulating valve. The regulating valve will admit the oil to the other side of the piston and the motion of the ram will get reversed. It is clear that the length of the ram stroke will depend upon the position of the t by unclamping and moving the trip dogs to the desired positions.\r\n\r\nThe above system is a constant pressure system. The velocity of the ram travel will be directly proportional to the oil pressure and since the piston area on which the oil pressure acts is greater as compared to the other end for which it gets reduced because of the piston rod. the hydraulic power to mechanical power for feeding the work past the tool.\r\nHydraulic\u00a0 Shaping machine Circuit Diagram\u00a0\r\n hydraulic shaper circuit Diagram\r\nShaping machine Forward Stroke :\u00a0\r\nAs shown in the figure, the pump is supplying oil to the Double actuating cylinder through the DC valve and through port B.

In general the shaper can produce any surface composed of straight line elements. Modern shapers can generate contoured surface. The shaper was first developed in the year 1836 by James Nasmyth, an Englishman. Because of the poor productivity and process capability the shapers are not widely used nowadays for production. The shaper is a low cost machine tool and is used for initial rough machining of the blanks.\r\n\r\n\r\n\r\nTypes Of Shaping Machine \/ Classification Of Shaping machine\u00a0\u00a0\r\n\r\n\r\n\r\n1. According to the type of mechanism used\r\n\r\n \tCrank shaper\r\n\r\nThis is the most common type of shaper in which a single point cutting tool is given a reciprocating motion equal to the length of the stroke desired while the work is clamped in position on an adjustable table. In construction, the crank shaper employs a crank mechanism to change circular motion of \u201cbull gear\u201d to reciprocating motion of the ram.\r\n\r\n \tGeared type shaper\r\n\r\nThe reciprocating motion of the ram is some type of shaper is effect by means of a rack and pinion. The rack teeth which are cut directly below the ram mesh with a spur gear. The pinion meshing with the rack is driven by a gear train. The speed and the direction in which the ram will traverse depend on the number of gears in the gear train. This type of shaper is not very widely used.\r\n\r\n \tHydraulic shaper\r\n\r\nIn a hydraulic shaper, reciprocating movement of the ram is obtained by hydraulic power. Oil under high pressure is pumped into the operating cylinder fitted with a piston. The end of the piston rod is connected to the ram. The high pressure oil first acts on one side of the piston and then on the other causing the piston to reciprocate and the motion is transmitted to the ram. The speed of the ram is changed by varying the amount of liquid delivered to the piston by the pump.\r\n\r\ntypes of shaper\r\n\r\n2. According to the position and travel of ram\r\n\r\n \tHorizontal shaper\r\n\r\nIn a horizontal shaper, the ram holding the tool reciprocates in a horizontal axis. Horizontal shapers are mainly used to produce flat surfaces.\r\n\r\n \tVertical shaper\r\n\r\nIn a vertical shaper, the ram holding the tool reciprocates in a vertical axis. The work table of a vertical shaper can be given cross, longitudinal, and rotary movement. Vertical shapers are very convenient for machining internal surfaces, keyways, slots or grooves. Large internal and external gears may also be machined by indexing arrangement of the rotary table. The vertical shaper which is specially designed for machining internal keyway is called as Keyseater.\r\n\r\n \tTravelling head shaper\r\n\r\nThe ram carrying the tool while it reciprocates moves crosswise to give the required feed. Heavy jobs which are very difficult to hold on the table of a standard shaper and fed past the tool are held static on the basement of the machine while the ram reciprocates and supplies the feeding movements.\r\n\r\ntypes of shaper machine\r\n\r\n3.\u00a0 According to the type of design of the table\r\n\r\n \tStandard or plain shaper\r\n\r\nA shaper is termed as standard or plain when the table has only two movements, vertical and horizontal, to give the feed. The table may or may not be supported at the outer end.\r\n\r\n \tUniversal shaper\r\n\r\nIn this type, in addition to the two movements provided on the table of a standard shaper, the table can be swiveled about an axis parallel to the ram ways, and the upper portion of the table can be tilted about a second horizontal axis perpendicular to the first axis. As the work mounted on the table can be adjusted in different planes, the machine is most suitable for different types of work and is given the name \u201cUniversal\u201d. A universal shaper is mostly used in tool room work.\r\n\r\n4. According to the type of cutting stroke\r\n\r\n \tPush type shaper\r\n\r\nThis is the most general type of shaper used in common practice. The metal is removed when the ram moves away from the column, i.e. pushes the work.\r\n\r\n \tDraw type shaper\r\n\r\nIn this type, the metal is removed when the ram moves towards the column of the machine, i.e. draws the work towards the machine. The tool is set in a reversed direction to that of a standard shaper. In this shaper the cutting pressure acts towards the column which relieves the cross rail and other bearings from excessive loading and allows to take deep cuts. Vibration in these machines is practically eliminated. The ram is generally supported by an overhead arm which ensures rigidity and eliminates deflection of the tool.","headline":"Types Of Shaping machine  | Classification Of Shaper","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-03-29","mainEntityOfPage":"False","dateModified":"February 20, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/03\/types-of-shaper-300x195.jpg","height":195,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/what-is-automats-types-of-automats-advantages-of-automats/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/03/SINGLE-SPINDLE-AUTOMATIC-CUTTING-OFF-MACHINE-300x120.jpg')"></div><span class="sr-only">link to What is Automats | Types of Automats | Advantages Of Automats</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/what-is-automats-types-of-automats-advantages-of-automats/">What is Automats | Types of Automats | Advantages Of Automats</a></p></header><div class="excerpt"><p>What is Automats | Types of Automats | Advantages Of Automats

The working cycle is fully automatic that is repeated to produce identical parts without participation of the operator.\r\nAll the working and idle operations are performed in a definite sequence by the control system adopted in the automats which is set up to suit a given work.\r\nClassification of Automats\r\nThe automats can be classified as follows:\r\n\r\nAccording to the type of work materials used:\r\n\r\n \tBar stock machine.\r\n \tChucking machine.\r\n\r\nAccording to the number of spindles:\r\n\r\n \tSingle spindle machine.\r\n \tMulti spindle machine.\r\n\r\nAccording to the position of spindles:\r\n\r\n \tHorizontal spindle type.\r\n \tVertical spindle type.\r\n\r\nAccording to the use:\r\n\r\n \tGeneral purpose machine.\r\n \tSingle purpose machine.\r\n\r\nAccording to the feed control:\r\n\r\n \tSingle cam shaft rotating at constant speed.\r\n \tSingle cam shaft with two speeds.\r\n \tTwo cam shafts.\r\n\r\nAdvantages of automats over conventional lathes\r\n\r\n \tMass production of identical parts.\r\n \tHigh accuracy is maintained.\r\n \tTime of production is minimized.\r\n \tLess floor space is required.\r\n \tUnskilled labor is enough.

Components with simple form are produced in this machine by means of cross sliding tools.\r\n\r\nConstruction \r\n\r\nThis machine is simple in design. The head stock with the spindle is mounted on the bed. Two cross slides are located on the bed at the front end of the spindle. The front cross slides are used for turning and forming operations. The rear tool slide is used for facing, chamfering, recessing, under cutting and cutting off operations. Cams on a camshaft actuate the movements of the cross slides through a system of levers.\r\n\r\n SINGLE SPINDLE AUTOMATIC CUTTING OFF MACHINE\r\n\r\nWorking principle \r\n\r\nTypical arrangement of tool slide in an automatic cutting off machine is illustrated in Fig. . The required length of work piece (stock) is fed out with a cam mechanism, up to the stock stop which is automatically advanced in line with the spindle axis, at the end of each cycle. The stock is held in the collect chuck of the rotating spindle. The machining is done by tools held in cross slides operating only in the crosswise direction. The form tool held in the front tool slide produces the required shape of the component. The parting off tool in the rear tool slide is used to cut off the component after machining. Special attachments can be employed if holes or threads are required on the\r\nsimple parts.\r\nThis machine has a single cam shaft which controls the working and idle motions of the tools. The cam shaft runs at constant speed. Therefore working motions and idle motions takes place at the same speed. Hence the cycle time is more. Typical simple parts (from 3 mm to 20 mm in diameter) produced on this machine are shown in Fig.\r\n\r\n&nbsp;","headline":"What is Automats | Types of Automats | Advantages Of Automats","author":{"@type":"Person","name":"Sachin Thorat","url":"\/\/www.gunkrazy.com\/"},"datePublished":"2019-03-29","mainEntityOfPage":"False","dateModified":"February 20, 2020","image":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2019\/03\/SINGLE-SPINDLE-AUTOMATIC-CUTTING-OFF-MACHINE-300x120.jpg","height":120,"width":300},"publisher":{"@context":"http:\/\/schema.org\/","@type":"Organization","name":"Learn Mechanical Engineering","logo":{"@type":"ImageObject","url":"\/\/www.gunkrazy.com\/wp-content\/uploads\/2020\/01\/learn-mech-logo-1-300x300.png","height":600,"width":60}}}</script> <article class="article-card horizontal "> <a href="//www.gunkrazy.com/what-is-collet-chuck-types-of-collet-chucks/" rel="nofollow"><div class="image-container" style="background-image: url('//www.gunkrazy.com/wp-content/uploads/2019/03/types-of-collet-chuck-diagram-300x101.jpg')"></div><span class="sr-only">link to What is Collet Chuck | Types Of Collet Chucks</span></a><div class="copy-container"><header><p><a style="color: #ff392e!important" href="//www.gunkrazy.com/what-is-collet-chuck-types-of-collet-chucks/">What is Collet Chuck | Types Of Collet Chucks</a></p></header><div class="excerpt"><p>What is Collet Chuck | Types Of Collet Chucks

A collet is a circular steel shell having three or four equally spaced slits extending the greater part of its length.\r\nThese slits impart springing action to the collet. That is why, collets are also known as \u201cspring collets\u201d. The collet nose is made thicker to form the jaws. The outside surface of the nose fits in the taper hole of the hood. The inside of the collet is made according to the shape of the work to be held. Collets are much more suitable than a self centering chuck in mass production work due to its quickness in action and accurate setting. The collets may be operated by hand or by power.\r\nTypes of collet Chuck :\u00a0\r\n The collets are classified by the methods used to close the jaws on the work.\r\n\r\ntypes of collet chuck diagram\r\nPush out type Collet chuck\r\nThe push out type collet chuck is shown in Fig. 2.68 (a). In this type the taper of the collet nose and hood converge towards the right. To grip the work, the tapered portion of the spring collet is pushed into the mating taper of the hood. There is a tendency of the bar to be pushed slightly outward when the collet is pushed for gripping. If the bar is fed against a stop bar fitted on the turret head, this slight outward movement of the bar ensures accurate setting of the length for machining.\r\nDraw back or Draw in type Collet chuck \r\nThe draw back type collet chuck is shown in Fig. 2.68 (b). In this type the taper of the collet nose and hood converge towards the left. To grip the work, the tapered portion of the spring collet is pulled back into the mating taper of the hood which causes the split end of the collet to close in and grip the bar. The machining length of the bar in this type of chuck cannot be accurately set as the collet while closing will draw the bar slightly inward towards the spindle.\r\nDead length type Collet chuck\r\nThe dead length type collet chuck is shown in Fig. 2.68 (c). For accurate positioning of the bar, both the push out and draw in type collet present some error due to the movement of the bar along with the collet while gripping. This difficulty is removed by using a stationary collet on the bar.\r\nIn this type the taper of the collet nose converge towards the left. A sliding sleeve is placed between the collet and the hood. This sliding sleeve has a tapered edge which fits on the taper of the collet nose. To grip the work, the sliding sleeve is pushed towards the right. This makes the collet to close in and grip the bar.
