This product is a kind of highly precise heavy-load lathe motorized spindle.whose max. speed could reach 4,500 rpm. With A2-6 nose and an installation diameter of 220 mm, the spindle is configured with 15 kW permanent magnet synchronous motor with rated and max. torsion of 95.5 Nm and 170.6 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.
And the same mounting size as the universal A2-6 external drive spindle, can be directly switched. As a kind of lathe motorized spindle that could satisfy the requirements of heavy cutting. 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: 15 kW
Rated torque: 95.5 Nm
Max. speed: 4500 rpm
Max. torque: 170.6 Nm
Voltage and encoder could be chosen based on the specific demands.
