  3. 3. Dividing head or indexing head is a special work holding device, which is bolted on the machine table.<br />The work may be mounted on a chuck fitted on the dividing head spindle or may e supported between a live and dead center. <br />The dead center is mounted on a foot stock as in a lathe tail stock that is bolted on the machine table after correctly aligning its spindle axis with the dividing head spindle. <br />Dividing Head<br />
  4. 4. The attachment is principally used for dividing the periphery f a work piece in equal number of divisions for machining equally spaced slots, or groves. <br />The worm and worm gear driving mechanism of the attachment can be linked with the table lead screw for cutting equally spaced helical grooves on the periphery of a cylindrical work piece<br />Dividing Head<br />

  6. 6. This attachment mounted on column of universal Milling machine.<br />Which consists housing spindle head and bevel drive gears<br />Vertical Head<br />
  7. 7. Vertical Head<br />
  8. 8. It’s used for profile milling and many other circular operations in horizontal plane such as slotting and dovetailing.<br />It’s consists a base, a worm drive mechanism and a small circular work table.<br />Rotary Table<br />
  9. 9. Rotary Table<br />
  10. 10. It’s used for cutting at any angle in vertical plane to produce key ways , slots and corners.<br /> It’s provide reciprocating drive for single point cutting tool.<br />Slotting Attachment<br />
  11. 11. Slotting Attachment<br />
  12. 12. It’s mounted between the face of column and outer support on a plain or universal milling machine.<br />It consists a fixed housing and a spindle.<br />A special rack indexing attachment used to move the work longitudinally with accurate spacing of teeth. <br />Rack Milling Attachment<br />

  14. 14. It’s used to mill spirals with a plain milling machine.<br />It’s useful for cutting helical threads , gears , worms and racks.<br />UNIVERSAL SPIRAL ATTACHMENT<br />
  15. 15. UNIVERSAL SPIRAL ATTACHMENT<br />
  16. 16. It is used to drive small milling cutters at high speed.<br />It may be fitted on vertical or horizontal machine.<br />It consists a housing contains step-up gearing and a small spindle.<br />HIGH SPEED ATTACHMENT<br />

  18. 18. PROPER MILLING CUTTER FOR A PARTICULAR JOB<br />
  19. 19. Milling cutters are usually made of high-speed steel and are available in a great variety of shapes and sizes for various purposes. You should know the names of the most common classifications of cutters, their uses, and, in a general way, the sizes best suited to the work at hand.<br />Classification of Milling Cutters<br />
  20. 20. Consider the following when choosing milling cutters:<br />High-speed steel, stellite, and cemented carbide cutters have a distinct advantage of being capable of rapid production when used on a machine that can reach the proper speed.<br />45° angular cuts may either be made with a 45° single-angle milling cutter while the workpiece is held in a swivel vise, or with an end milling cutter while the workpiece is set at the required angle in a universal vise.<br />Selection of Milling Cutters<br />
  21. 21. The harder the material, the greater will be the heat that is generated in cutting. Cutters should be selected for their heat-resisting properties.<br />Use a coarse-tooth milling cutter for roughing cuts and a finer-toothed milling cutter for light cuts and finishing operations.<br />When milling stock to length, the choice of using a pair of side milling cutters to straddle the workpiece, a single-side milling cutter, or an end milling cutter will depend upon the number of pieces to be cut.<br />Selection of Milling Cutters<br />
  22. 22. Some operations can be done with more than one type of cutter such as in milling the square end on a shaft or reamer shank. In this case, one or two side milling cutters, a fly cutter, or an end milling cutter may be used. However, for the majority of operations, cutters are specially designed and named for the operation they are to accomplish.<br />The milling cutter should be small enough in diameter so that the pressure of the cut will not cause the workpiece to be sprung or displaced while being milled.<br />Selection of Milling Cutters<br />
  23. 23. In selecting a milling cutter for a particular job, choose one large enough to span the entire work surface so the job can be done with a single pass. If this cannot be done, remember that a small diameter cutter will pass over a surface in a shorter time than a large diameter cutter which is fed at the same speed.<br />Size of Milling Cutter<br />
