PTG-32 CNC Punch Grinder ※Patent Pending

Accuracy Rigidity Efficiency

PTG-32 CNC punch grinding machine, integrated with TOPWORK’s years of experience in the field of tool grinder, is especially developed for the punch industry. It uses Delta OPEN CNC controller as its frame and is equipped with the iGrand formed surface grinder software.

Features

PTG-32 Structure

The spindle adopts 5 precision angular contact ball bearings. The horsepower is upgraded to 5HP. The center of mass of the spindle is right at the center of the Z axis ,which provides you the stability.

 
Wheel spindle
  • The spindle adopts 5 precision angular contact ball bearings. The horsepower is upgraded to 5HP. The center of mass of the spindle is right at the center of the Z axis ,which provides you the stability.
 
Workhead
  • The MT4 taper of the working head adopts direct drive to improve the indexing accuracy. It is equipped with a six-jaw chuck, the range is from diameter 3 to 32 mm, that can freely match different diameter of the workpieces.
 
V-shaped supporter
  • When the punch is grinded, the supporter is used to improve the grinding stability. The V-shaped supporter with bilateral adjustment can reduce the calibration time. 
 
Standard dressing device
  • The standard dressing device is coned diamond dresser or you can upgrade to diamond disk dressing device to dress the grinding wheel in process which can ensure the grinding accuracy of punches and improve the grinding efficiency.
 
Diamond disk dressing device(Opt.)

Controller and Software

Common modules
  • Punch grinding CAD software, which is built-in 7 common modules for the punch industry. Then, you can generate more figures by changing the number of sides. The dialog operation interface only needs to input various parameters with different icons.
Custom template
  • Custom template is built, and users can draw a needed grinding shape by themselves.
Path simulation
  • The CAM function automatically generates the grinding path according to the grinding figure and parameters, which performs grinding wheel dressing and grinding path simulation, then uploads the NC program to the controller for actual production.
  • During grinding, wheel dressing can be performed during the process. So the automatic compensation, dressing and grinding can be completed at one time.
