OEM magnetic chuck manufacturers for 15 years

OEM magnetic chuck manufacturers, safe milling magnetic chucks




magnetic chuck for surface grinding, EDM, magnetic attraction gap fine
distribution, when machining thin small parts is especially effective.




Charge,
when demagnetization precision table unchanged. 




Panel with a special treatment,
no leakage to prevent cutting fluid corrosion and prolong life sucker, can work
a long time on the cutting fluid.




Six surface grinding process. 




Magnetic chucks
are assembled by rare earth permanent magnet with high energy product, high
coercivity. The pull strength can reach 100N /cm2.

In 2013 we
innovated ultra-dense type pole pitch 2 + 0.5 overall copper panel suction far
exceeds the national standard,

with the original close-pole pole pitch 4 + 1
compared to full copper panel, to better adsorption workpiece grinding.

permanent magnetic lathe chuck workholding

Strong force, easy operating, safe using, fast shipping

Features of magnetic lathe chuck: 

Simple, lightweight, rugged, energy constant, absolutely reliable, suction up to 100N/c㎡. Whether in the field of 

heavy or light industry, permanent lifting is the indispensable tool of handling the workpiece or blank pieces.

It is easy-operated  and safe.

Strong suction,small remanence and light weight. It is made of permanent magnet and 

never demagnetized if properly used. And it is free of electricity, to avoid the risk of power outages and 

connection. Magnetic chuck is suitable for surface grinder, spark machine,wire cutting machine tool.

With dense Pole gap and even-distributed magnetic forse,it is more advantageous in small workpiece 

machining.
