How do I set the Machine to Machine the soft jaws on the chuck?

1 comments:

Mr. Anderson

February 10, 2025

To machine the soft jaws on the chuck using the GSK980TDc CNC system, follow these steps:

1. Set the Clamping Mode: If using hydraulic clamping, ensure the correct mode (inner or outer chuck) is selected. Adjust system parameters if switching between internal and external clamping.

2. Install the Soft Jaws: Mount the soft jaws onto the chuck and secure them properly.

3. Set Workpiece Coordinates: Define the workpiece coordinate system according to the machining process. Ensure alignment with the chuck.

4. Program the Machining Process: Create a CNC program to machine the soft jaws accurately. Use appropriate cutting tools such as rough turning, finish turning, and grooving tools.

5. Adjust Machining Parameters: Set spindle speed, feed rate, and cutting depth according to the material and tool specifications.

6. Run the Program: Start the machining process while monitoring for accuracy and stability.

7. Verify Jaw Fitment: After machining, check the jaws to ensure they properly grip the workpiece.

These steps ensure the soft jaws are machined correctly for precise clamping.

Page 441: Step/Mpg Adjustment
Chapter 4 Machine Debugging methods and Modes The CW clamping duration setting should be proper, it should be neither longer nor shorter, longer delay may damage the motor, shorter delay may cause the tool post not to be completely clamped. The method to check the tool post clamping is: approach the dial-indicator to the tool post, turn the tool post manually, and the pointer floating of the dial-indicator should not be over 0.01mm.

Page 465: Chapter 6 Memorizing Pitch Error Compensation
There are more or less precision errors in the pitch of machine axes lead screw, and it will definitely affect the parts machining precision. This GSK980TDc CNC system has the memorizing pitch error offset function that it can accurately compensate the pitch error of the lead screw.

Page 467 Chapter 6 Memorizing Pitch Error the position No.001 in the offset table from the machine zero. So the pitch error offset can only be done in the positive moving direction of the machine coordinate system. The position No.000 in the offset table corresponds to the reference point (i.e. pitch error origin 0), the offset point 1 corresponds to a point of positive 10.000 moving from this reference point, and a following offset point from this point every 10.000 interval.

So there is a offset point every 10.000 from position 61, the 127 offset point corresponds to the offset of position +670.000.
Page 469 Chapter 6 Memorizing Pitch Error offset point from this point every -10.000 distance. The offset point 1 is the offset at position -1260.000. Therefore, at offset point 127, set a offset value of a moving from 0 to -10.000, at offset point 126, set a offset value of a moving from -10.000 to -20.000.
