Surface grinding (Surface G)

View More
Grinding the plane of a workpiece (work). There are cases where grinding is performed on the side surface of the cylindrical grindstone and grinding is performed on the cylindrical surface. In general, grinding on the side of the grinding stone gives a finished surface with good surface roughness and dimensional accuracy, and grinding on the

Flat Grinding Wheel (Straight)

We have added lineup of abrasive grains and bonding materials (bonds) that are ideal for high efficiency, high precision, emphasis on surface roughness, etc., as well as various work materials (workpieces). We will propose improved grindstone of Mitsui grinding whetstone.

Disk wheel (Disk)

It can handle various workpieces (work) processed from stainless steel (SUS) raw material to nitrided steel, with single-sided and double-sided surface grinding machines and CBN · DIA wheels.

Disk grinding wheel (raw material) Disk (for Soft Steel)

By special manufacturing method with high porosity, it is excellent in sharpness and has a strong abrasive grain holding power, so it is possible to set a coupling degree softer than conventional resinoid grindstone, realizing high grinding ratio. Compared with ordinary resinoid stone, there is no dropout of extra abrasive grains, so processing accuracy improves if the same grain size.

Disk grinding wheel (for spring) Disk (for Spring)

In the heavy grinding process of the spring, the heat absorbing property which is the feature of the magnesia grinding stone exerts the force, and the thermal damage of the workpiece (work) is reduced. It realizes high precision and stable grinding processing.

Ring grinding wheel (Ring)

We offer grinding wheels that can be polished more finely and finely in the re-grinding of flat blades such as cutting, woodworking and pulverizing blades and round blades such as chipsaw. Mitsui's grinding stone softly hits the blade, realizing a good sharpness and finished surface.

Segment Wheel (Segment)

We have added lineup of abrasive grains and bonding materials (bonds) which are ideal for high efficiency, high precision, emphasis on surface roughness, etc., as well as various work materials (workpieces). We will propose improved grindstone of Mitsui grinding whetstone.

Centerless grinding (Senterless G)

View More
Support the workpiece (workpiece) with three of the grinding wheel, adjusting wheel, and receiving plate (work rest) and grind the outer circumferential surface. Because the center and chuck are not used for supporting workpieces, it is easy to install and remove workpieces, and it is one of the grinding methods indispensable for mass production grinding.

Cylindarical Grinding (Cylindarical G)

View More
The workpiece which is supported by the center at both ends by grinding the outer surface of a cylindrical workpiece (work). There are traverse grinding which performs grinding while moving a grindstone parallel to the axial direction of a workpiece, plunge grinding where a grindstone or workpiece is moved in the radial direction of the grinding wheel, and other angular grinding.

Roll Grinding (Roll G)

View More
A method of regrinding a steel rolling roll for molding such as a beverage can, an aluminum foil and so on. It is a grinding process performed for surface regeneration and shape modification of the rolling roll.

Rice Mill (Rice Mill G)

View More
A method of removing sugar in brown rice with a grinding wheel in the rice milling process which removes sugar and makes it into white rice. It is applied to rice polishing machines, rice polishing machines for sake brewing and so on.

Knife Grinding Stone
