Which type of Lathe is operated through Cams and Cam plate?

Explanation:

• A lathe is a machine tool on which surfaces of revolution can be produced.
• Generally, the workpiece rotates, and the cutter moves relative to the workpiece.

• A lathe is a machine tool that holds the job in between the center and rotates the job on its own axis.
• Due to this quality of holding the job from the center and rotating the job, it is called the center lathe.
• There are different types of lathe:
  • Speed lathe
  • Engine lathe or Centre lathe
  • Bench lathe
  • Toolroom lathe
  • Capstan and turret lathe
  • Special purpose lathe
  • Automatic lathe
  • CNC machine
  • Precision Lathe

Capstan and turret lathe:

• These are developed from engine lathe, used for production work.
• The tailstock of an engine lathe is replaced by a hexagonal turret where a number of tools can be mounted.
• A number of identical parts can be produced in minimum time.

Precision Lathe

• Capable of giving a dimensional accuracy of 0.002 mm.
• The precision turning of the previously rough-turned workpiece. 
• In many cases, replace a high class grinding machine because of its fine dimensional accuracy.

Screw Cutting Lathe (automatic)

• It is operated through cams and cam plates.
• It is used for mass production of screwed parts. Especially suitable for precision screw work.

Crankshaft Lathe

• It carries all the attachments, like taper turning and threading, etc.
• In addition, a number of rests (supports) for the shafts.
• It is used for turning very long parts such as turbine and engine shafts and crankshafts.
