Have you mastered any reasonable methods for distinguishing the quality of precision electric spindles? The following points may be helpful to you:

1. The manufacturing is relatively rough

The common ones are the motor parts of various electric spindles, such as bearing seats, washers, etc. According to high requirements, these are actually a process that requires rough grinding, grinding, fine grinding, and then fine grinding, while relatively low-priced spindles generally only achieve the first two steps. Some even use precision machining instead of grinding. Therefore, there is a significant difference in the quality and price of the spindle.

In CNC and other machining processes, the requirements for precision electric spindles are very high. If the precision runout and other indicators do not meet the standards, the quality of the processed products will be affected to varying degrees.

2. Choose low-grade bearings.

The price of bearings varies greatly depending on the grade. It can be imagined that low-quality and low-priced products have good quality, so we hope that consumers can carefully distinguish them when purchasing.

3. Replace various raw materials

To reduce costs, on the one hand, it is necessary to reduce the manufacturing process; On the other hand, the most effective method is to replace various raw materials.

Some common substitution phenomena in the market include using aluminum, rubber covers instead of iron, and so on.

4. Inventory or second-hand spindle

Industry insiders know that as long as you know some skills, you can reprocess the old spindle through surface polishing and other processes. Polishing the old spindle in this way may make it look brand new, and the cost will be very low. However, the used thing seems to have no problems in terms of accuracy and performance. In fact, the performance and accuracy fluctuations of the parts have already had a negative impact on your future workpiece processing.
