CNC vertical lathe is a kind of high-precision machining equipment. This equipment has very high requirements on the quality and requirements of bearings during the processing process. Next, this article will combine the actual situation with an in-depth discussion of the technical requirements of CNC vertical lathes for bearings from the two aspects of CNC vertical lathe equipment and bearings.

First of all, from the perspective of CNC vertical lathe equipment, CNC vertical lathes usually use high-speed rotating tools for processing, so they need to meet the following requirements when processing bearings:

1. High geometric accuracy requirements for bearings: CNC vertical lathe is a high-precision machining equipment, so it requires very high geometric accuracy for bearings, such as bearing diameter, roundness, flatness, verticality, coaxiality, etc. These requirements can be tested through the use of high-precision measuring instruments.

2. High material requirements: Since CNC vertical lathes use high-speed rotating tools for processing, the material requirements for bearings are very high, and they must have high strength, high hardness, wear resistance and other characteristics. Commonly used bearing materials include steel, stainless steel, copper, aluminum, etc.

3. Low surface roughness requirements: During the processing process, CNC vertical lathe equipment has the characteristics of high-speed cutting and high-density cutting lines, so the bearing surface roughness requirements are relatively low, generally Ra0.8μm-1.6μm. During the machining process, attention should be paid to keeping the bearing surface smooth and free from surface defects such as tool marks and flaws.

Secondly, from the perspective of bearings, CNC vertical lathes also have certain technical requirements for bearings, as follows:

1. The coaxiality of the inner and outer rings of the bearing is required to be high: During the process of processing bearings, CNC vertical lathe equipment needs to ensure the coaxiality of the inner and outer rings to ensure its normal operation. During the use of the bearing, the coaxiality must not deviate, causing damage to the product or abnormal operation.

2. Strict requirements for bearing roundness and diameter error: During the processing of bearings, certain roundness and diameter errors need to be maintained, otherwise it will cause noise, vibration and other problems during the operation of the bearing.

3. High precision requirements for bearings: CNC vertical lathe processing of bearings requires high precision to meet the precision processing requirements of CNC vertical lathes and at the same time ensure the production quality of the bearings.

CNC vertical lathes have very high technical requirements for bearings, including bearing geometric accuracy, material, surface roughness, inner and outer ring coaxiality, roundness and diameter errors, accuracy and other requirements. Only by meeting these requirements can we ensure the processing accuracy of bearings by CNC vertical lathes and ensure the quality and service life of bearings.
