Equipment Highlights

Large Vertical Pit-Type Resistance Furnace

Ideal for heat treating large, heavy, and long workpieces (such as shafts and rollers)

Heavy-Duty Horizontal Lathe

Used during the turning stage of roller manufacturing, Specifically utilized for the precision turning of large-scale mill rolls.

Vertical Turning-Milling Composite Machine

Ideal for machining large, heavy, asymmetrical castings and forgings, the large gearbox housing, etc

5-Axis Gantry-type Machining Center

Its primary application is the machining of workpieces with extremely complex geometries and stringent precision requirements. It is widely used in the aerospace, automotive mold manufacturing, and energy equipment industries.

6-Axis CNC Machining Center

A multi-spindle machining center features an array of spindles, enabling the simultaneous machining of multiple parts. It is ideal for high-volume milling and drilling of small to medium-sized parts.

High-Speed Precision CNC Machining Center

High-rigidity precision linear guides are used on the X, Y, and Z axes. The automatic tool changer, driven by a high-precision roller cam, operates quickly and reliably. The Z-axis is equipped with a motor brake system, which maintains high stability and responsiveness even during rapid positioning to ensure machining accuracy.
