Marketing globally under the dual brands CHENG YI and LJR, CHENG YI is based on its superior technology and experience, constantly challenging leading German and Swiss brands. The highest concentricity accuracy of the lathe collets and lathe guide bushings it provides has reached within 0.003mm, which is the same as that of Japanese manufacturers, making it the best helper for efficient operation of production lines at any time.

"Our guiding principle is to be courageous in taking on challenges and never give up. No matter how difficult the drawing is, we will try to make it first. If we can make it, it is our own product." Liao Guowen, general manager of Cheng Yi Company, said that the highest concentricity accuracy of the lathe collets and lathe guide bushings produced by Cheng Yi has reached within 0.003mm. The product accuracy is on par with that of Japan. At present, the inner hole range of HSS collets is 0.5-65mm, and the inner hole range of tungsten steel collets and guide bushings is 0.5-51mm. We also produce ceramic guide bushings for stainless steel processing, which can meet the increasingly sophisticated processing requirements.

"Our definition of standardization is that the concentricity accuracy of the 13mm inner hole of the collet is within 0.005mm. This is not only the precision of Japan, but also the precision that requires additional payment," said Liao Guowen. He explained that no matter how good the machine is, it cannot operate properly without collets or guide sleeves of relatively high precision. Just like a car, no matter how good it is, it cannot perform its intended function without the corresponding tires. However, unlike buying from Japanese companies, which is more expensive and requires additional payment, Cheng Yi's high-precision collets are more affordable. Flexible production can meet customers' needs for large-volume deliveries in a short period of time.

Collets and guide sleeves, like tires, are small parts but indispensable components in manufacturing, affecting the yield and production schedule of all products. Liao Guowen explained, "Because collets affect the time technicians spend calibrating machines, lower-precision collets, although cheaper, require technicians to spend more time calibrating them. Therefore, many people are willing to spend more money to buy high-precision collets, so that technicians can complete the calibration and start production in the shortest time. This is why many of our customers come to us."

Currently, Cheng Yi has partnered with 64 lathe and milling machine manufacturers worldwide, and its products are sold in 29 countries across Europe, America, and Asia. Cheng Yi provides high-quality parts for computer-controlled lathes, including collets, guide bushings, internal cutting tools (ant cutters), drill bits, sliding sleeves, collet bushings, tie rods, front covers, guide bushings, collet bushings, non-powered tool holders, powered tool holders, drilling shafts, ER collets, water-stop collets, and tapping collets. These parts effectively reduce costs and are the top choice for major lathe manufacturers to enhance their competitiveness. For inquiries, please call (04) 865-2727.
