Feature
- 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.

Box Ways
These highly rigid box way structures give you the very best machine durability. The material is high-frequency-heat-treat for stress relief.
The 4-in-1 design for base body slideways enhance the cutting capabilities in the Z-axis.
High Precision Slide Ways
Our auto grease lubricating system provides several advantages for the overall machine capability.
It not only maintains high accuracy during the long working hours, but also functions perfectly with low speed machining. The high precision ball screw axis transmission provides superior machine stability resulting in highly accurate work pieces.
R2 & R3 provides 2 additional linear slide ways to enhance durability and eliminate unwanted deflection. This significantly improves machine cutting accuracy
Rotary working table
The bed slideway is box way, adopted roller bearing and worm-gear equipped force lubricated system. Table center equipped Heidenhain rotary encoder assure index accuracy. Table equipped Hydraulic clamping system & positioning pin, assure indexing angle 0°, 90°, 180°, 270° heavy cutting accuracy.
