OCD-CAM
CNC Series
250 / 400 / 600 / 1000 mm
Distance between centers
Ø320 mm
Swivel over table
Ø300 mm
Max. external grinding dia.
For various eccentric circle or non-round shape workpieces grinding purpose, PALMARY develop CNC Cylindrical Grinder Cam Type for easily transfer from workpiece drawing to grinding program. The workhead could offer precise angle control due to the C axis has accurate angle encoder.
The working spindle carried with precision angle decoder, high resolution of angle control.
The infeed axis is driven by linear motor with linear guideway & close loop linear scale, it could avoid the backlash in order to reach high machining precision. Also, it could prevent the reaction force causing by linear motor under the large acceleration and deceleration motion, it could stabilize the grinding process.
Retaining various functions of CNC cylindrical grinder, and applicable to angle and speed control.
Main Structure of the CNC cylindrical grinder, when in combination with angle control of spindle by C axis (built-in spindle motor), is capable of grinding various special shaped workpiece.
