High-Precision Milling Machines: 

Yih Shan offers a range of high-precision milling machines with capabilities including 3-axis, 4-axis simultaneous, 4.5-axis, and 5-axis simultaneous milling functions. Such versatility enables us to meet the complex processing requirements for free-form surfaces and compound surfaces across various products.

High-Precision Lathe Processing: 

Catering to the unique processing characteristics of different products, our plants are equipped with specialized high-precision CNC lathes in designated areas. 
The equipment includes Feed-Type Lathes, which are engineered for stability and durability, accommodating larger diameters and excelling in heavy cutting operations, espicially suitable for processing large workpieces. 
Additionally, we utilize Center Lathes, designed for high precision, capable of producing small-diameter parts while also efficiently handling the processing of longer workpieces.

Turning and Milling Machines: 

Yih Shan operates high-precision turning and milling compound machines that can process multiple axes (X1, Y1, Z1, C1, X2, Y2, Z2, C2, X3, B). 
This integration of production processes enhances workpiece accuracy and production efficiency, ensuring we meet our customers’ quality and efficiency requirements.

Automatic Lathe Processing: 

The cam-type automatic lathes are high-performance and high-precision machines. The type is particularly suited for the processing and manufacturing of precision parts made from materials such as copper, aluminum, iron, and plastic. These lathes are ideal for batch production of small components used in various industries, including instrumentation, watch and clock, automotive, motorcycle, bicycle, eyewear, stationery, hardware, sanitary ware, electronics, plug-ins, computers, mobile devices, electromechanical products, and defense industries.
