Product Summary

The JXZ70-680 End Facing and Centering Machine is a heavy-duty CNC lathe designed for precision shaft and disk part machining. With a machining diameter range of 14-500mm and length range of 70-5000mm, it integrates multiple processes including face milling, center hole drilling, external cylindrical turning, drilling & tapping, chamfering, boring, and rapid U-drilling in a single clamping. The machine bed is integrally cast from high-quality gray cast iron HT300, providing exceptional rigidity and stability for heavy cutting applications. It is widely used in automotive, agricultural machinery, motor, railway, construction machinery, transmission, gear, and new energy industries.

Key Selling Points

• High Rigidity: Integrally cast HT300 gray iron bed ensures stable heavy cutting and long-term deformation resistance, suitable for 24-hour continuous operation.
• Multi-Function in One Setup: Combines face milling, center hole drilling, turning, drilling & tapping, chamfering, boring, and U-drilling, reducing process steps and labor.
• Exceptional Precision: Repeat positioning accuracy 0.008-0.012mm; center hole depth consistency at both ends ±0.05mm (customizable to ±0.02mm); surface roughness Ra1.6-Ra1.8.
• Automation Ready: Supports single-machine intelligent operation and integration into automatic production lines for unmanned processing, with tool wear compensation, anti-collision, and MES system connectivity.
• Wide Application Range: Machining diameter 14-500mm and length 70-5000mm covers most shaft and disk parts in automotive, heavy machinery, motor, and transmission sectors.

Technical Specifications

Models and Options

Base model: JXZ70-680. The machine can be configured with different control systems (KND, GSK, Siemens, Fanuc, or Juxin proprietary). Optional accessories include automatic chip conveyor, power turret, tool magazine, and hydraulic fixtures.

Materials and Structure

The machine bed is integrally cast from high-quality gray cast iron HT300, offering exceptional rigidity and vibration damping. This design ensures long-term stability and precision even under heavy cutting loads. The bed’s robust structure supports 24-hour continuous production without deformation.

Case Study

Automotive OEM (since 2014): Supplied end facing and centering machines for half shaft, brake disc, and gear shaft machining. Integrated into automatic production lines with unmanned operation, long-term fault-free performance. The client, a top domestic automobile manufacturer, acknowledged Juxin as the fastest domestic machine tool supplier in acceptance and commissioning.

Siemens (Germany): Juxin CNC end facing and centering machines are used for precision machining of motor spindles and shaft parts. The machines seamlessly connect with Siemens global intelligent production lines, meeting German process requirements. This made Juxin the first domestic machine tool supplier admitted into the Siemens global supply chain.
