This product refers to a kind of heavy-load lathe motorized spindle, whose max. speed could reach 4,500 rpm. With A2-6 nose and an installation diameter of 240 mm, the spindle is configured with 22 kW permanent magnet synchronous motor with rated and max. torsion of 140 Nm and 431 Nm respectively. It can be configured with 8” and 10” chuck and oil cylinder and used for finish turning and heavy cutting of steel parts, casting and nonferrous metals as well as installation of Type 52 CNC lathe and turning-milling composite machine tool.
As a kind of lathe motorized spindle that could satisfy the requirements of heavy cutting, it is mainly applied to such fields as motor, aerospace, hardware, etc.
1. Application of high-performance heavy load bearing:
The rigidity is ≥800N/μm through optimizing bearing application, making it applicable to 5mm heavy cutting of stainless steel. The processing efficiency is also high.
2. High-performance permanent magnet synchronous motor:
Rated power: 22 kW
Rated torque: 140 Nm
Max. speed: 4,500 rpm
Max. torque: 431.7 Nm
3. Diverse configuration:
Voltage and encoder could be chosen based on the specific demands.
