Description
CNC vertical spline rolling machine VDS800EA is suitable for the precision chip-free cold forming of straight teeth, spiral teeth(splines), thread, worm, straight grain, oil groove on shaft parts of automobile gearbox gear shaft, ball cage constant speed universal joint, spline shaft, motor shaft, textile roller, spring torsion bar, directional machine, crankshaft, etc.
Features
- Wear-resistant castings use special materials frame body is highly rigid.
- Unique synchronization gap trimming technology can improve synchronization accuracy.
- Rich combination mold can reverse forming and save molds.
- Clamping one time can form a few steps.
- Intelligent rail war lubrication detector function, workpiece forming finished with the big cooling flow.
- Reasonable structure design, pleasant operating height, small footprint.
- CNC spline rolling machine can carry with truss or joint robot and automatic line.
- The machines are driven by a dual-servo motor in a fully closed-loop, synchronous manner, realizing low-noise precise forming.
- The technology of smart full-servo front and rear centers effectively solves safe clamping identification.

Spline Shaping Principles
The spline cold forming is actually a shaping process without stock removal, in which root materials are gradually extruded and replaced up to the crest.
Through our computation procedure, you can easily figure out the theoretical diameter of materials necessary for shaping and you can get the final diameter after adjustment.
Advantages of cold forming: (compared with old cutting processing)
1) efficiency is increased up to more than 30 times.
2) workpiece bearing capacity is increased to 40%.
3)roughness can reach below Ra0.4.
4)materials saved to 9%-15%.
5)fatigue strength, torsion strength, and wear resistance are sharply improved.
