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. WORK SPACE : - center height - 150mmAdmit between wkhd &
