At present, CNC machine tools are developing at a high speed in the direction of higher precision, higher reliability and maintenance free. Behind it, the technology of key parts has played an important role in boosting. For example, bearings, ball screws and linear guide rails are precision parts indispensable to NC machine tools. They can be described as the heroes behind the scenes of the machine tool industry.

在精机直动产品方面，推出了全球的高精度长寿命滚珠丝杆，独特的表面改性技术提升了油膜形成能力，实现了滚珠丝杠性能长期稳定化，针对模具加工等严苛环境（低速，短行程往复）能够对磨损进行有效抑制，保持机床的长期稳定加工精度，延长设备维护周期。推出的低象限突起滚珠丝杠技术大幅提升滚珠丝杠运行方向反转时摩擦稳定性，降低机床运动误差，配合系统控制，可将机床象限突起控制到1um以内，提升加工面品质，确保在高品质的同时提升机床加工效率。

In terms of precision machine direct acting products, the world's leading high-precision long-life ball screw is introduced. The unique surface modification technology improves the oil film forming ability and realizes the long-term stability of the performance of the ball screw. In view of the harsh environment such as mold processing (low-speed, short stroke reciprocating), it can effectively inhibit wear and maintain the long-term stable machining accuracy of the machine tool, Extend equipment maintenance cycle. The low quadrant protrusion ball screw technology greatly improves the friction stability when the running direction of the ball screw is reversed, reduces the motion error of the machine tool, and can control the quadrant protrusion of the machine tool to less than 1um with the system control, so as to improve the quality of the machining surface and ensure the high quality and improve the machining efficiency of the machine tool at the same time.

在精密轴承方面，高负载容量、超高速角接触球轴承ROBUSTDYNATM 系列，通过对内部零件和结构的化以良好应对低速重切削加工和高速高品质加工，提高了轴承的耐压痕性，并降低了主轴碰撞损伤等风险，采用自主研发的耐热性、耐磨损性能优异的SHX材料，可实现dmN值300万的超高速性能。

In terms of precision bearings, the robustdynatm series of high load capacity and ultra-high speed angular contact ball bearings, through the optimization of internal parts and structures, can well cope with low-speed heavy cutting and high-speed high-quality processing, improve the bearing pressure resistance and reduce the risk of spindle collision damage. SHX materials with excellent heat resistance and wear resistance are adopted, It can achieve ultra-high speed performance with DMN value of 3 million.

在直线导轨方面，通过优化滚动体（滚珠）和导轨沟槽之间的接触面压力分布，采用了独有的TF化热处理技术，设计开发了具有高可靠性的DS、DH系列直线导轨，运行寿命可达原产品的2倍。

In terms of linear guide rail, China has optimized the pressure distribution on the contact surface between the rolling element (ball) and the guide rail groove, adopted the unique TF heat treatment technology, and newly designed and developed DS and DH series linear guide rails with high reliability, with a service life up to twice that of the original products.

耐冲击主轴轴承技术、高精度长寿命滚珠丝杠、超高精度直线导轨、丝杠导轨的免维护的润滑单元等，能够提高加工品质和效率，并带来优异的耐久性能和故障预警，使机床长时间保持良好的加工精度。为用户的降耗贡献一份力量。

Impact resistant spindle bearing technology, high-precision long-life ball screw, ultra-high-precision linear guide rail, maintenance free lubrication unit of lead screw guide rail, etc. can improve processing quality and efficiency, bring excellent durability and fault early warning, and keep good processing accuracy of the machine tool for a long time. Contribute to the energy saving and consumption reduction of users.
