OCD-3225CAM / 3240CAM / 3260CAM / 32100CAM


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.


Work spindle

The working spindle carried with precision angle decoder, high resolution of angle control.


Feed axis

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.


Various cylindircal grinder functions

Retaining various functions of CNC cylindrical grinder, and applicable to angle and speed control.


C axis angle 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.
