CNC lathe MJ0830

horizontal2-axisslant bed

The MJ0830 is a slant-bed CNC turning lathe equipped with a 12-station servo turret and a 15 kW direct-drive spindle (A2-6). Designed for rigidity, low vibration and accurate turning, the MJ0830 supports automation and auxiliary modules to enable one-lathe two-step processing and high productivity.

Key product highlights

• High-performance direct-drive spindle with constant torque and low vibration.
• Rapid response on start/stop and speed changes for stable cutting performance.
• Customized 12-station high-rigidity servo turret for fast tool indexing and heavy turning.
• High-rigidity box guideway carriage; linear guideway available as an option.
• Hydraulic tailstock standard; programmable hydraulic tailstock or sub-spindle optional for two-step processing.
• Designed for integration with automation: bar feeders, robots, gantry systems and parts handling devices.
