More questions buyers ask
What is a Close Pole Permanent Magnetic Chuck?
A close pole magnetic chuck is a workholding device with a dense pole arrangement, designed to provide superior holding force for small to medium-sized ferromagnetic workpieces during grinding or EDM operations.
What are the main advantages of Crystal Close Pole Chucks?
They offer high and uniform magnetic holding power, a steel and brass laminated top plate for durability, and are perfectly parallel for high-precision machining.
Which industries use these magnetic chucks?
They are widely used in tool rooms, die and mold making, precision grinding shops, and general engineering fabrication units.
What is the pole pitch of these chucks?
The Crystal Close Pole series features a 30 mm pole pitch (15 + 2.5 + 10 + 2.5 mm), optimized for better magnetic penetration and grip.
Are these chucks suitable for light milling?
Yes, they are suitable for light milling and rough grinding jobs, providing stable holding for various ferromagnetic materials.
How do I operate the magnetic chuck?
Each chuck comes with an easy-to-operate on-off lever for quick workpiece setup and release.
What maintenance is required?
Keep the top plate clean and free of burrs. Regularly check the lever mechanism and ensure the bottom mounting surface is clean for accurate clamping.
Can these be used on EDM machines?
Yes, they are ideal for spark erosion (EDM) machine setups where stable, precise holding is required.
Do you provide a warranty?
Yes, Crystal products come with a standard manufacturer warranty against manufacturing defects.
Is pan-India delivery available?
Yes, we offer secure, pan-India delivery for all industrial magnetic chucks.
How do I choose the right size?
Select a chuck size that accommodates your largest workpiece while fitting your machine table dimensions. We offer sizes ranging from 250x150mm to 750x250mm.
What is the difference between close pole and fine pole?
Close pole chucks provide deeper magnetic penetration for thicker parts, whereas fine pole chucks are better suited for very thin, small components.
Who should choose the 250x150mm model?
Ideal for small-scale tool rooms and precision grinding of compact components.
Who should choose the 750x250mm model?
Best for large-scale fabrication and heavy-duty grinding tasks requiring extensive table coverage.
How does the 250x150mm compare to the 750x250mm?
The 250x150mm is compact and cost-effective for small jobs, while the 750x250mm offers maximum surface area and holding capacity for large industrial projects.
