Moving Column



High productivity.

The AC digital wrap around spindle drive and motor are more accurate and responsive than traditional analog spindle drives and motors.

The spindle performance is continuously monitored to provide the most efficient cutting conditions.

Each axis is independently controlled to provide maximum feed as required.

CBA Series box way

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 CBA-110R and CBA-110R2 bed slide ways enhance the cutting capabilities in the Z-axis.

Rotary table

This special combination of highly rigid box ways, ball screws, and worm gear automatic lubrication system provides a highly satisfying compact rotary table design.

With the Heidenhain angle encoder installed in the rotary table center shaft, combined with our specially designed hydraulic clamping system and positioning index pins, our machines can achieve any cutting angle.

Reinforced heavy cutting angles at 0∘, 90∘, 180∘and 270∘are included features.

Hence resulting in superior accuracy and cutting efficiency.

Ease of operation

Fanuc, Siemens, and Heidenhain control panels are available options.

These value added features will enhance your working capability, efficiency, and much more.

We are sure that you will be very satisfied with the high level of quality and improved machine performance.

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.

The CBA-110R3 provides 2 additional linear slide ways to enhance durability and eliminate unwanted deflection.

This significantly improves machine cutting accuracy.

Power spindle

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 very highest quality spindle Bearings from SKF and NSK.

These high quality bearings insure machine consistency and a longer machine life.
