Premier Radial Pole Chuck Ideal for a wide range of precision grinding and medium/ heavy turning applications, the radial pole is the best option for ring type applications such as inspection and precision grinding. The radial pole is the best option for heavy turning on ring type components. The design concentrates the entire magnetism from the chuck to the point in contact with the workpiece, ensuring excellent hold. The workpiece on this type of chuck should not cover more than 50% of the pole area.
Variable hold on both parallel and radial pole versions (Operating handle can be stopped in any position) Provides option of partial (variable) hold essential for clocking the work concentrically prior to switching to full power.
Through bore All sizes of the radial pole chucks from the 150mm diameter and above are supplied complete with a through bore.
A blanking plug is available for when the bore is not required.*
The bore is ideal for through spindle coolant applications. * N/A for NR100C.
Radial Pole is radially balanced While the switching principle is the same on all of the premier range the radial pole version uses a round magnet pack that rotates to switch. This ensures that the chucks stay in balance when rotating and can be spun up to a maximum of 3000rpm.
