Which Brand Of Small Machining Center Is Better?

Which brand of small machining center is better?

Choosing a spindle when choosing a machine tool is like choosing an engine when buying a car. This core component directly determines whether the part you are processing is a work of art or a waste product. The spindle brands on the market today are mixed, and the prices range from thousands to tens of thousands. If you choose the wrong one, not only will the surface finish fail to meet the required standards, but there may also be frequent shutdowns that require repairs, delaying the project deadline and wasting money.

Spindle quality determines machining accuracy

The cutting surface quality of more than 80% of machining centers is determined by the spindle. The stability and rigidity of the high-speed rotation of the spindle will have a direct impact on the finish and dimensional accuracy of the workpiece. In 2025, there was a mold factory in Dongguan, Guangdong. Because it was cheap, it chose an off-brand spindle. Vibration marks appeared on the surface of the molds that were finally processed, causing the entire order worth 200,000 yuan to be scrapped.

The runout index reflects the precision of the spindle. When a high-quality spindle is running at high speed, the radial runout can be controlled within 0.002 mm. This value is equivalent to one-thirtieth of the diameter of a human hair. However, when an inferior spindle runs for half an hour, its temperature soars to more than 60 degrees, which causes thermal deformation and affects the processing accuracy.

Technical status of Continental spindle units

At present, the proportion of spindles produced in mainland China used in machining centers is actually not high. According to statistics from the Machine Tool Industry Association in 2025, the market share of domestic spindles in vertical machining centers only accounts for about 15%. The reason for this is mainly due to the fact that there are still gaps in core technologies such as high-speed spindle bearings and lubrication systems.

Mainland China's spindle manufacturing companies are mostly concentrated in the two provinces of Zhejiang and Shandong. There are more than 30 spindle manufacturers in Cixi, Zhejiang. However, most of them can only manufacture products with ordinary speeds up to 12,000 rpm. However, when it comes to spindles that require high-speed operation accuracy of more than 20,000 rpm for machining centers, users usually turn to Taiwan or imported brands.

Market structure of spindle brands in Taiwan

The Naitaidao spindle brands that dominate the mainland market, Danquan brand, Jianchunlong brand, Pusen brand, and Luoyi brand, these four brands account for more than 60% of the mid-to-high-end market share. In the first half of 2025, Jianchunlong's shipments in Kunshan, Jiangsu have reached 8,000 sets, which are mainly used to support vertical machining centers for use.

Danquan focuses on high rigidity and heavy cutting, and is the choice for processing mold steel. Different brands have different positionings. Pusen focuses on high speed and is suitable for high-speed cutting of aluminum alloy parts. The price of Danquan products with the same specifications is about 15% more expensive than Pusen, and the delivery time is ten to fifteen days longer.

Spindle price fluctuations and selection strategies

In the past two years, the price of spindles has shown a significant increase. Look at the Jianchunlong 170 spindle. In 2023, its price was still at the level of 23,000 yuan. However, by 2025, it had risen to 31,000 yuan, an increase of more than 30%. This price increase is mainly due to the increase in prices of core components such as imported bearings and screws, as well as the increase in labor costs.

The choice of spindle must be determined based on the processing object. For those who mainly use aluminum alloy 3C product parts as the processing object, it is enough to choose a high-speed spindle that can reach a speed of more than 12,000 rpm. If you are cutting stainless steel medical devices, it is different. You must choose a heavy-duty cutting spindle with high torque. In 2025, there was a valve factory in Taizhou, Zhejiang, which brand of small machining center is good. Due to an error in the selection of the spindle type, when processing the stainless steel valve body, the machine was frequently shut down.

Configuration flexibility of machining center manufacturers

They are all regular machining center manufacturers and all support spindle customization. When you are in the stage of purchasing a machine tool, you can clearly tell the manufacturer what kind of material you want to process, what the accuracy requirements are, and how many hours of working time you need every day. In this way, the manufacturer will match you with the most suitable spindle brand and specifications based on the information provided, instead of directly assembling the standard spindle.

If you require a customized spindle, you must communicate the delivery date in advance. Under normal circumstances, if the spindle is modified to a Taiwanese brand, the production cycle will increase by 15 to 20 days, and the price difference is within the range of 5,000 to 15,000 yuan. In 2025, there was a machinery factory in Qingdao, Shandong Province. When signing the contract, it requested to switch to Danquan spindle. As a result, although it took 18 days longer, the processing efficiency increased by 25%.

Support and prospects of domestic brands

Currently, there are some spindle manufacturers in Wuxi and Luoyang. The products produced by such manufacturers show good performance in drilling and tapping centers and engraving and milling machines. If the budget allows, then you can try to support domestic brands. In the field of 3C processing, Wuxi Kaiyuan spindle's market share has reached 20%, and its price is about 30% cheaper than Taiwanese brands.

The after-sales service response of domestically produced spindles is faster. Luoyang Shaft Research Institute has more than 50 service outlets across the country. After receiving a repair call, it can arrive at the site to start processing within 24 hours. However, Taiwanese brands need to wait for parts to be shipped from Taiwan, which usually takes 3 to 5 days to complete the repair.
