1. Replacing various raw materials: Undoubtedly, to reduce costs, on the one hand, it is necessary to reduce the manufacturing process; On the other hand, a more effective method is to replace various raw materials. Some common substitution phenomena in the current market, where copper replaces aluminum, will have a certain impact on the performance of motors. And after using aluminum, it is relatively much cheaper than copper. There are also iron substitutes for certain types of rubber caps, and so on.

2. Inventory or second-handElectric spindleExperts must know that as long as you have some technical knowledge, you can use surface polishing and other reprocessing treatments to turn old electric spindles into new ones. This way, regardless of the cost, it will be very low. However, the used things seem to have no problems in terms of accuracy and performance. In fact, the performance and accuracy fluctuations of the parts have already had an impact on your future processing of things. What comes here is inventory. There are no truly large-scale electric spindle manufacturers in China, and they are relatively small and medium-sized enterprises. Moreover, the number of domestic manufacturers producing this type of electric spindle has grown significantly every year. After purchasing from one manufacturer for a period of time, another one is purchased and used, and after a period of time, another one is used due to factors such as price, resulting in products that were originally shipped under normal circumstances not being sold in a timely manner, leading to a backlog of products. Also, due to product backlog, if the product cannot be sold, then this type of motor is like scrap metal! Some factories may lower these prices due to cost considerations, even if they are not profitable. Due to cost considerations, they will also use this method for promotion.

3. The manufacturing is relatively rough: the common ones are the motor parts on various electric spindles, such as bearing seats, washers, etc. According to high requirements, these actually need to go through a process of rough grinding, grinding, fine grinding, and then fine grinding, and electric spindles with relatively low prices usually do the first two steps! Moreover, there is a significant difference in the quality and price of electric spindles. In CNC and other machining processes, the requirements for the electric spindle are very high, and the accuracy and runout indicators cannot be met, which will affect the quality of the processed products to varying degrees. The losses caused by this are simply incomparable to the money spent on purchasing an electric spindle.

4. The choice of bearings: The price of bearings is currently different from the precision level of bearings, and there is also a significant price difference. The price of all ceramic ball bearings can reach thousands, while the price of ordinary high-speed bearings is often very cheap, even a few yuan. It can be imagined that what kind of bearings would be used for low-quality and low-priced products sold for 400-500 yuan? I hope that consumers can carefully distinguish when making purchases.
