FAQ

Q1: What's Permanent Electro magnetic chuck ?

A1: Permanent electro magnetic chuck is a new workholding applied in metal cutting process. Comparing to traditional clamping tools, it have the advantage of 5-sides workable at single clamp, less deformation, higher efficiency, clamping force exist even after power failure.

Q2: Permanent electromagnetic chuck(PEM chuck) VS Electromagnetic chuck(EM chuck), which one is better?

A2: Permanent electromagneitc chuck use the Neodymium magnet inside as the energy to hold metal workpieces. It’s free of power during working, except few seconds when MAG & DEMAG. While Electromagnetic chuck need continuous current to transfer into magnetic holding force. That means PEM chuck have better efficiency and accurancy and less deformation and consumptions.

Q3: Will water cooling in my CNC machine disturbing for working with magnatic plate?

A3: The Permanent Electromagnetic chuck use high performance epoxy resin to fill in the gap of poles, and could protect the surface from coolant oil and water.
