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.

Appearance;

1, the pole
should be neat sucker, uniform appearance should not have scratches, cracks,
corrosion, perforations, dents, burrs and other defects;

2, sucker
installed base and the work surface roughness Ra of not more than 1.6μm.

Geometric
accuracy:

Chuck type	Bottom surface flatness (not convex allowed)
Rectangle Disc	Length <300mm, tolerance: +/-0.01mm, each additional 100mm, tolerance increased 0.005mm
	Bottom surface Parallelism(not convex allowed)
	+/-0.03mm, each additional 100mm, tolerance increased 0.01mm

Performance test：




Suction test methods:




 Magnetic chuck is placed on the working
platform, wrench open. When the test piece from the table (dimensions see
table); the respective test blocks suck sucker countertop, 




each test point
location drawings, dynamometer by non-magnetic clasp is perpendicular to the
table, slowly pull test block.




The dynamometer is the biggest indication
countertops sucker suction at this point. Each sucker suction data in Table II.

Chuck Item	Normal	Intensive	Super Intensive	Strong Chuck	Measuring Tools
Suction requirements（N/cm2）	>100	>100	>100	>150	0-200N
Suction inhomogeneity（N/cm2）	<20	<20	<20	<20	0-200N

Left, within a magnetic force to suction
off the magnetic 10S test pieces leave the table when the method of operation
is consistent with suction test.











2. wrench control force test methods:










The magnetic chuck fixed on the test bench,
dynamometer hooking on the end of the handle, slowly pull dynamometer in the
vertical direction, 




the sucker opening and closing process, the dynamometer
indication is the maximum operating force wrench, standard values in Table
III.




Note: during the inspection process, the dynamometer
is should be always perpendicular to the handle
