Marketing globally under the dual brands CHENG YI and LJR, CHENG YI provides integrated manufacturing services for lathe parts based on its superior technology and experience. The precision and reliability of its products exceed international standards. Its CNC internal turning tools have been tested and found to have a durability that is more than 3 times that of leading international brands. The rapid tool change design within 30 seconds makes it the best assistant for efficient production line operation.

With the goal of surpassing leading international brands, Cheng Yi Company has achieved a concentricity accuracy of less than 0.003mm for its lathe collets and guide bushings, bringing the product precision close to Japanese standards. Currently, HSS collets are produced with an inner diameter range of 0.5-65mm, and tungsten steel collets and guide bushings are produced with an inner diameter range of 0.5-51mm. The company also produces ceramic guide bushings for stainless steel processing, which can better meet the increasingly sophisticated processing requirements.

Liao Guowen, general manager of Chengyi Company, said that cutting tools are a crucial part of CNC lathe machining, and the reliability of a single cutting tool can affect the operation of the entire automated production line.

Cheng Yi Company has introduced German five-axis grinding machine production equipment, uses imported materials from Germany and Japan, and draws on the experience of leading global brands to provide solutions. Through integrated machining and forming design processes, coupled with careful adjustment and design, Cheng Yi CNC internal turning tools (ant tools) have smooth chip removal and durability that leads domestic manufacturers and even surpasses international brands such as Israel. Actual tests show that their durability can be 2 to 3 times greater.

"We want to make it easy and quick for everyone to change cutting tools!" Liao Guowen said. Traditional tool changing procedures are cumbersome, and in the absence of a master supervisor during night shifts, the negligence of foreign workers or novices often leads to defective products or production line shutdowns, affecting delivery dates or output value. Cheng Yi CNC internal turning tools feature a quick-positioning design, allowing even beginners to change tools in 30 seconds without needing to set or add tools, thus promoting efficient production line operation.

Currently, Cheng Yi collaborates with 64 lathe and milling machine manufacturers worldwide, and its products are sold in 28 countries across Europe, America, and Asia. Cheng Yi provides a wide range of CNC lathe parts, including sliding sleeves, collet bushings, tie rods, front covers, guide sleeve outer bushings, collet bushings, non-powered tool holders, powered tool holders, collets, guide sleeves, drilling shafts, ER collets, water-stop collets, and tapping collets. All parts are rigorously selected and designed by Cheng Yi, and coupled with professional consultant services, they meet the needs of one-stop purchasing. This makes Cheng Yi a top choice for major lathe and machinery manufacturers to enhance their competitiveness.
