PMI Precision Motion Industries
(1) High reliability
PMI has accumulated many years experience in production managing. It covers
the whole production sequence, from receiving the order, designing, material
preparation, machining, heat treating, grinding, assembling, inspection, packaging
and delivery. The systemized managing ensures high reliability of PMI Ballscrews.
(2) High accuracy
PMI Ballscrews are machined, ground, assembled and Q.C. inspected under the constant temperature control (20°C) to ensure high precision of Ballscrews accuracy inspection certificate.
(3) Long durability
PMI Ballscrews are made of German Alloy steels, which are well quenching and tempering treated for good rigidity, along with suitable surface hardening to ensure
(4) High working efficiency
Balls are rotating inside the Ballscrew nut to offer high working efficiency. Comparing with the traditional ACME screws, which work by friction sliding between the nut and screw, the Ballscrews needs only 1/3 of driving torque. It is easy to transmit linear motion into rotation motion.
(5) No backlash and with high rigidity
The Gothic profile is applied by PMI Ballscrews. It offers best contact between balls and the grooves. If suitable preload is exerted on Ballscrew hence to eliminate clearance between the ball nut and screw and to reduce elastic deformation, the
ballscrew shall get much better rigidity and accuracy.
Large Load Capacity
No Angular Backlash
Ball Retaining Type
Robots, Transporting Equipment, Wire Winder, ACT(auto tools change), etc.
