Air-Speed High Precision SPindles
MA Series - Modular Type
22.8mm (0.89”) Spindle Dia., 58,000 Max RPM, 108W (0.14HP) Max Power; 25/25.4mm (0.98/1.0”) Spindle Dia., 24,000 Max RPM, 130W (0.17HP) Max Power; 30mm (1.18”) Spindle Dia., 19,000 Max. RPM, 130W (0.17HP) Max Power
Pneumatic Spindles
The MA Series has been designed to operate smoothly at high speeds for long continuous cutting and grinding by connecting an air line kit directly between the air compressor and the air motor. Separate motors and spindles provide flexible application changes. Easy to interchange the components
Features
- Gang slide NC lathe can be transformed into complex machining centers
- Specialized machine design will be made compact and universal
- Mounting MA Series on existing equipment can eliminate secondary operations or the equipment can be turned into a special purpose machine
- Applicable to secondary operation machines, single purpose machines or special machining and grinding machines
- The air motors are explosion proof and do not generate heat even in continuous use
- When the MA Series is used at low motor speeds, a speed reducer (AR-01, or other selections) is added to obtain the speed of your choice
- A collet, Jacobs Drill Chuck, saw arbor and grinding stone arbor are available for grinding, drilling, milling, slitting, chamfer and deburring operations
- High Torque versions available
MS Series - One Piece Type Spindle
19.05 mm - 25.4 mm (0.75” - 1.0”) Spindle Diameters, 1,400 - 30,000 RPM, max 130W (0.17HP)
Pneumatic Spindles
A shorter overall length suitable for CNC lathes and special purpose machines. Hardened and precision ground for high rigidity and excellent durability. External one-piece housing includes both the motor and spindle.
Features
- Outer housing material (SUS416) is precision ground to +0/-0.01mm
- Either staight or 90º air connection types are avialable depending on mounting and plumbing restrictions
- Very high spindle accuracy makes ultra-precision machining possible
- The design of NAKANISHI's air motors gives the highest output power in this small spindle class
- Silencer on the exhaust air tubing greatly reduces noise
- Speed reduction system
