Compound Sine Permanent Magnetic Chuck
Compound sine permanent magnetic chucks combine permanent magnetic holding with compound sine angle adjustment. They are suitable for precision grinding of ferromagnetic workpieces that require controlled angular positioning in more than one direction.
Send the workpiece size, required grinding angle, angle adjustment direction, holding area and grinding setup, and we will help check the suitable compound sine permanent magnetic chuck model.
Product Overview
Compound sine permanent magnetic chucks are used when the workpiece requires precise angular positioning in compound or multi-direction grinding setups. They differ from standard sine permanent magnetic chucks by supporting more complex angle adjustment requirements.
How a Compound Sine Permanent Magnetic Chuck Works
A permanent magnetic top plate closes the magnetic circuit through the ferromagnetic workpiece, while two sine-adjustment stages provide angular positioning in different directions. Each stage is set from its sine geometry and reference height, then locked before grinding. Compound-angle accuracy depends on both settings and their interaction, whereas magnetic holding depends on material permeability, thickness, pole coverage, contact area and air gap.
Typical Applications
- Compound angle grinding of ferromagnetic workpieces
- Precision workpieces requiring multi-direction angle positioning
- Tool and fixture grinding setups
- Applications where permanent magnetic holding and angular adjustment are both required

Selection Notes
Please provide workpiece size, required grinding angle, adjustment direction, holding area and grinding setup details.
When a Compound Sine Magnetic Chuck Is Not Suitable
Do not select a compound sine chuck when only one simple angle is required and a more rigid single-axis setup is sufficient. It is unsuitable for non-ferromagnetic workpieces, inadequate pole contact, angles outside either listed adjustment range, or setups where the combined tilt causes tool, wheel or machine interference. Both axes must be independently set and locked; looseness, debris or reference error in either stage affects the final compound angle.
FAQ
What is a compound sine permanent magnetic chuck used for?
It is used for precision angular grinding and positioning of ferromagnetic workpieces where compound-angle adjustment is required.
How is it different from a sine permanent magnetic chuck?
A sine permanent magnetic chuck is used for single-direction sine-angle positioning, while a compound sine permanent magnetic chuck is used when compound or multi-direction angle adjustment is required.
What information should I provide for model selection?
Please provide the workpiece size, required grinding angles, holding area, setup direction and machine arrangement so the suitable compound sine permanent magnetic chuck can be confirmed.
What compound angle requirement should be confirmed?
Please confirm whether the application needs single-angle, dual-angle or compound-angle positioning, as well as the usable angle range in each direction.
What workpiece size and contact area should be checked?
Please confirm the workpiece material, size, thickness and magnetic contact area so the correct working surface and holding capacity can be selected.
What machine table or setup condition should be confirmed?
Please confirm the grinder table size, mounting interface, required height, dressing clearance and available setup space before selecting the model.
What should be checked before installation?
Check the base flatness, angle adjustment mechanism, magnetic on-off function, mounting position and workpiece support stability before use.
What information is needed for quotation?
Please provide workpiece drawings, required angle range, machine table size, holding area and application details so the suitable compound sine permanent magnetic chuck can be recommended.
