WHAT MAKES OUR CNC ROUTER MACHINE SO DIFFERENT FROM THE OTHERS?

OUR CNC ROUTER MACHINES ARE USING BALL SCREW SPINDLE DRIVE.


BALL SCREW SPINDLE DRIVE

 

þ The ball screw nuts are of high quality, precise and abrasion-resistant (hardened and polished).

þ Together with the ball screw spindles, they convert rotations into linear movements with minimal friction.

þ The repeatability is less than 0.02 mm at a length of 300 m.

þ The ball screw spindles are produced with modern machines; they are rolled, hardened and polished.

þ Our linear drives are technically mature and have stood the test in practice for more than 20 years.

However, other brands of CNC Router machine are using Rack & Pinion Type, Timing Belt Type, and Lead Screw Type of spindle drive



Rack and Pinions can be an endless source of problems. When chips or dirt falls on the rack, the pinion gear has to go “over it” resulting in loss of positioning accuracy and vibration. The racks constantly need adjusting to tighten them and after tightening them in one spot, you are more than likely to be too loose or too tight on another area of the rack. This will causes the system to be either too loose or to bind.

This does not happen with a ball screw because the balls roll over a formed thread. Since they roll, we can tighten up the fit between the screw and ball nut without causing the system to bind.
