Neostar – Permanent Radial Pole Chuck
Neostar chucks with Neodynium (rare earth) magnet material are designed for holding rings and bearing races, as well as solid rounds. This chuck comes standard without center hole. An optional through hole can be provided upon request. Common uses are holding rings, bearing races, as well as solid rounds.
Ferromax – Rotary Permanent Magnetic Chuck
These chucks provide dependable magnetic holding for rotary surface grinding and light turning applications. The top plate is magnetic with each pole individually magnetized by powerful ceramic permanent magnets, so electrical controls and collector rings are not required. Frequent magnet polarity changes result in low magnet field to prevent magnetization of tool bits. Common uses are rotary surface grinding, lathe applications, and auxiliary tooling applications.
Multi-Pole Circular Chuck
Rotary electromagnetic and electro-permanent chucks are made in radial pole multi-coil design for use in hard turning and free state grinding. The radial pole design is recommended for holding circular workpieces such as rings and discs. Most radial pole chucks come with t-slots, but tapped holes are also available for mounting tooling. The smaller chucks four or six poles, while the larger chucks use a ten or twelve pole design. Common uses are hard turning and free state grinding.
