LA-600A
High-speed, High-precision Attachment Spindle for Micro-machining
| LA-600A, attached to your existing NC milling machine or machining center, will realize high-speed machining. At a high speed of 60,000min-1(rpm) , this spindle displays superior cutting performance and finishing in small-diameter end-mill cutting or drilling. |
 |  |
Maximum revolution speed : 60,000min-1 (rpm)
Spindle accuracy : 1μm or better
High power of max. 370W output and flat torque characteristic
A combination of brushless motor and ceramic bearing
The spindle is driven by a direct-drive brushless motor. Without any speed increase with gears or the like, this spindle causes little heating or vibration, which contributes to producing finely finished surface.
esponsive to various attaching tapers
The spindle can be fitted to various tapers of BT, HSK and other shanks.
