Description

Technical Field

[0002] CNC machine tools are widely used in the field of precision machining in modern industry. They are high-precision and fully automatic, and are important production and processing equipment. The spindle is the core component. Once there is a dimensional deviation, it will lead to errors in the size of the finished parts during the processing. Therefore, the spindle generally needs regular maintenance and inspection to determine whether it has any deflection or vibration.

[0003] Most of the existing machine tool spindle inspection methods rely on technicians to perform manual measurements using tools such as calipers and micrometers. This can easily lead to insufficient measurement accuracy and low efficiency due to tool problems or human factors. There is a lack of relatively faster and more accurate measuring equipment.

[0004] In order to solve the above problems, we have made improvements and proposed a CNC machine tool spindle detection device. Utility Model Content
