CAM GRINDING MACHINE

This cam grinding machine is specially designed for grinding of various cylindrical profiles. It was originally developed for grinding punches used in the pharmaceutical (tablet making) machines.A master-cam (MC) is required which is then used to generate a generating-cam (GC) the GC in turn is used for grinding profile of components. An MC is an exact (one-to-one) replica of the finished profile. From the MC a GC is made. This generating cam is then used for producing the profiled components. The GC is made on cam grinding machine itself using the MC. For grinding the cam/profile on a work-space the machine has a stationary follower on which the GC rests. The rotation of the GC provides oscillating movement to the work-head which is holding the work-piece. The GC coordinates the rotary & radial movements required for developing the necessary profile on the work-piece. SPECIFICATION :- The cam grinding machine consists of following major assemblies:-- work head,- Work slide (longitudinal slide),- Longitudinal positioning mechanism,- Wheel head- Wheel head slide (with hydraulic rapid retract)- Wheel head cross feed mechanism,- Follower positioning slides (X & Z direction)- feed mechanism for X & Z positioning- sub-base- Electrical controls- Hydraulic system & coolant system.
