The specially designed spindle outer ring cooling system maintains constant bearing accuracy under normal operating conditions.
This gear type auto-shift design and grease lubrication system also provides superior machine performance and reliability.
The spindle and boring bar are made of SACM645 alloy. The spindle has been Nitrided to HRC62~68. This hardness maintains spindle form and insures high reliability. This increased rigidity increases the overall machine capability.
We use the high quality spindle bearings to ensure machine consistency and a longer machine life.
