Heavy-duty CNC double-sided grinding machines are typically used to machine larger, heavier, or more accurate workpieces.
When there are problems related to surface scratches, the following aspects can be considered to solve them:
1. Grinding parameter adjustment:
Grinding pressure and speed:
Adjust the pressure and speed of the grinding head to avoid exerting excessive force on the surface of the workpiece and reduce the possibility of scratches.
Grinding Wheel Selection:
Use a grinding wheel that is suitable for the material and surface processing requirements of the workpiece, and select the appropriate sand grain size and grinding wheel hardness to reduce the damage to the surface of the workpiece.
2. Check the grinding device
Grinding head condition:
Make sure the grinding head or grinding wheel is not worn or broken, which could lead to scratches or uneven grinding surfaces.
Balance of the grinding head:
An unbalanced grinding head can cause vibrations and irregular scratches, so it's important to make sure the grinding head is in good balance.
3. Workpiece fixation and positioning:
Magnetic adsorption or clamping method:
If magnetic attachment or clamping is used to hold the workpiece, it ensures that the fixation is uniform and stable, avoiding additional stresses or deformations during machining.
Workpiece support and positioning:
Ensure that the workpiece is well supported and positioned during machining, avoiding scratches caused by vibration or instability.
Fourth, check the process:
Cleaning process:
Workpieces and machines are cleaned before and after machining to ensure that no foreign matter or grinding residue is present that could damage the surface during machining.
Monitoring and adjustment of the grinding process:
Parameters and results in the machining process are constantly monitored and adjusted and improved as needed.
5. Check the compatibility of materials and processes
Workpiece material and grinding process:
Make sure that the material used matches the grinding process to avoid scratches caused by unsuitable materials or improper processes.
The above suggestions can help solve the problems related to surface scratches in the machining process of heavy-duty CNC double-sided grinders.
