Common faults and causes of grinding machines

Release Time:

2025-08-22

1. When grinding workpieces on a surface grinder, there are ripples. 

Causes: 1. Is there lubricating oil on the Z-axis guideway? 2. Has the grinding wheel been statically balanced? 3. Is the radial runout of the spindle normal?
2. Causes of dimensional deviations during workpiece processing: 1. Is the dynamic level of the machine tool good? 2. Check the processing process. 3. The flatness of the worktable can be checked using a dial indicator to determine if it is caused by guideway wear.

1. Wavy patterns appear on workpieces during grinding on a planar grinding machine.  

Causes:  

1. Check if the Z-axis guideways have lubricating oil. 2. Check if the grinding wheel has been statically balanced. 3. Check if the spindle radial runout is normal.  

2. Processing accuracy exceeds specifications during workpiece processing.  

Causes:

 1. Is the machine tool's dynamic leveling good? 2. Check the machining process. 3. Use a dial indicator to measure the workbench surface flatness error value, which can determine whether it is caused by guide rail wear.  

3. Grinding machine oil leakage  

Causes:  

1. Check if the lubrication is excessive. 2. Check if the seals are damaged. 3. Check if the return oil holes are blocked. 4. Check if the oil pipes are damaged.

 4. Workbench Crawling

Causes:

1. Whether the workbench guideways are scratched 2. Whether there is oil on the guideways 3. Whether the seals on the piston are damaged 4. Whether air has entered the high-pressure oil

5. Workbench Speed

Causes:

1. Whether the guideways have lubricating oil 2. Whether the hydraulic oil is too dirty 3. Whether the filter screen is blocked (too dirty) 4. Whether the internal holes of the pump are damaged

Application scenarios for high-precision CNC grinding machines

High-precision CNC grinding machines are mainly used in the following scenarios:

Working Principle of High-Precision CNC Grinding Machine

‌Multi-Axis Interlocking‌: Five-axis CNC grinding machines can complete complex surface processing, enhancing processing flexibility.

What is the hourly rate for a high-precision CNC grinding machine?

The hourly rate for high-precision CNC grinding machines is typically between 60 and 80 yuan per hour, with specific costs adjusted based on equipment specifications, processing complexity, and regional differences.

What are the key structural components of a circular table surface grinder?

The circular table planar grinding machine, with its efficient and stable processing performance, has become a core piece of equipment for many manufacturing enterprises.

What are the structural characteristics and factors affecting processing accuracy of vertical spindle circular table surface grinders?

The core feature of a vertical spindle circular table surface grinder is its vertically arranged spindle and horizontally rotating worktable.

Advantages and disadvantages of vertical composite grinding machines

The above analysis is based on a comprehensive review of publicly available information; actual use may involve other specific issues.

Which is better: aluminum shell motors or cast iron motors?

The choice between aluminum shell motors and cast iron motors depends on the specific application scenario.
