High-speed, High-precision Spindle LA-600 for Micro-Machining
The high-speed, high-precision spindle LA-600 is a high-speed spindle unit fine-tuned to meet micro-machining needs. Rotating at the high speed of 60,000 revolutions per minute, the spindle demonstrates outstanding cutting performance and finishing accuracy in end-mill or drill machining.
| Maximum revolution speed : 60,000min-1 (rpm) | Spindle accuracy : 1μm or better |
| A combination of air cooling and ceramic bearing realizes the speeds of 10,000 to 60,000min-1 (rpm) . | The spindle accuracy is better than 1μm. Even the dynamic run-out accuracy is within the control. |
Compact size and high-rigidity stainless steel body
| The spindle body is as short as 149mm. The motor and spindle exteriors are all stainless steel (SUS420J2). The spindle clamp, which is hardened and grinder-finished, are of high-rigidity specifications. |

Principal Uses
- Use as tooling for end-mill machining or grinding with an end-mill or grinding wheel attached to the spindle end on a comb-type lathe.
- Use for small-bore hole finishing (bore polishing) in a lathe operation.
- Use for deburring, drilling (by a drill) or slitting by a metal saw with this spindle attached to a dedicated machine.
- Use for deburring or polishing with this spindle attached to the end of a robot arm.
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.

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.
