Main Feature:

R&D Innovation Structural Multi Guide Way 
The Bed is designed with 5 guide ways .

Processing guide ways won't interfere with the guide way for workpiece.

The design of leadscrew set in the middle let the effect of saddle movement to be more smoother.

Special design for apron support guide way to provide larger cutting capacity with heavier load.

Lathe over 4 meter will be mounted an extra linear way to strength the support capacity,

increase the processing accuracy, and reduce the abrasion of ball screws.

• 1. Once completed processing procedures
• This lathe is designed with multiple guideways. Because tailstock or steady rest are fixed on the 4th, 5th guideways and saddle slides on the 2nd, 3rd guideways while processing, it overcome completely the interference between saddle, tailstock and steady rest. Let saddle and tool turret complete smoothly the turning & processing procedure, operate easily and conveniently. (See fig.1))
• 2. The smooth internal drive
• Saddle, the bracket of ball screw and ball screw are mounted between the 2nd and 3rd guideway to correspond with each other. This distributes stress dispersed between the saddle and 2nd, 3rd guideways evenly when ball screw drives the saddle, enable ball screw drive the saddle more smoothly.
• 3. Cutting large diameter, more stable, more precision
• The saddle and tool rest travel along the 2nd and 3rd guideway, which is different from general configuration that suspended the cutting tool rest outside the 2nd guideway. This unique design increases higher of stability and precision while large diameter of workpiece.
• 4. Increase the cutting speed and stability of sliding
• While processing, even the cutting tool rest is shifted to the top or outside of the 2nd guideway, the equipment of the saddle and tool rest traveling along the 2nd and the 3rd guideway provide support to absorb the torsion caused from cutting work on the saddle & tool rest. This innovation gives outstanding stability and the accuracy.
• 5. Box-Bottom Bed Design
• High - rigidity body structure, the main structures of all aircraft used high MEEHANITE material. One piece casting. Box at the bottom of the design and strengthen their internal structure, raise the cutting strength of large workpiece.
• 6. Auto. lubrication system
• Auto lubrication system is controlled by PLC; oil will feed fixed volume for X / Z-axes during operating. There are two judging ways for feeding oils during operation. It will judge to feed oils automatically when cutting to a fixed length or machine's running to a fixed time.

7. Tailstock  Self-Rotary quill, when the main spindle turns, the tailstock's quill turns simultaneously (synchrony) with the main spindle, which lightens the load while raising stability. Mounted with taper roller bearings can bear heavy duty cutting. The quill is hardened and precision ground, adopted worm gear type design for quill's extending and retracting matched with gear motor, that is controlled easily and has the effect of anti-retract function on quill. The main body of tailstock matched with gear motor can move smoothly. The base of tailstock matched with rack equipment has an effect to prevent the tailstock body from retraction.
