KORRETTO · permanent magnetic chucks
Permanent Magnetic Chuck
Permanent magnetic chucks use permanent magnetic force to hold ferromagnetic workpieces during grinding and related machining operations. They are suitable for conventional surface grinding and flat magnetic workholding where continuous electrical power during holding is not required.
Send the workpiece size, material, holding area, grinding machine table size and required chuck dimensions, and we will help check the suitable permanent magnetic chuck model.
Product Overview

FAQ
Do permanent magnetic chucks require continuous power during machining?
No. Permanent magnetic chucks hold workpieces through permanent magnetic force and do not require continuous power during holding.
What is the difference between a permanent magnetic chuck and an electromagnetic chuck?
A permanent magnetic chuck uses permanent magnetic force for holding, while an electromagnetic chuck uses electrical power to generate and control magnetic force.
What information should I provide for model selection?
Please provide workpiece size, material, holding area, grinding machine table size, required chuck dimensions and application details.
What workpiece material and thickness should be checked?
Please confirm that the workpiece is ferromagnetic and provide the thickness, size and magnetic contact area so the suitable permanent magnetic chuck can be selected.
What machine table or installation interface should be confirmed?
Please confirm the machine table size, mounting surface, required working area and installation method before choosing a model.
Is it suitable for grinding, inspection or light milling?
Permanent magnetic chucks are commonly used for grinding, inspection and flat workholding. Whether they are suitable for milling depends on the cutting load and application conditions.
What should be checked before installation?
Check the base flatness, chuck surface cleanliness, magnetic switch operation and workpiece support coverage before production use.
What information is needed for quotation?
Please provide the workpiece material, size, thickness, holding area, machine table dimensions and machining application.
