Standard products

Selection Criteria

Feature

• Hard abrasive materials are sintered at high temperature with a vitrified bond, providing excellent cutting performance and durability.
• Since the grinding stone is firmly attached to the handle, it will not break easily.
• The structure allows force to be applied easily, making it ideal for manual polishing.

Product List (Boron Carbide)

• Dimensions: Total Length 150L
• Grinding Stone: 45×12×5
• The hard type is marked with “Hard” on the case and stamped with Ⓗ at the bottom of the handle.

Product List (Diamond)

• Dimensions: Total Length 150L
• Grinding Stone: 40×12×1.5
• There is an engraving at the bottom of the handle indicating the grit size.

Feature

• Carefully selected diamond abrasive grains are uniformly dispersed by a special manufacturing method, ensuring stable grinding performance.
• The paste has very low viscosity, which provides excellent workability.
• Even when diluted with a dedicated diluent, the diamond abrasive grains do not detach or separate.
• Since no coloring agents or chemicals that could negatively affect grinding are used, it can be safely applied to non-ferrous metals.

Product List

Feature

• Centerless grinding performance is greatly influenced by the quality of the control grinding stone and the dressing method, which directly affect machining accuracy and work efficiency.
• In addition to standard products, also offer a wide range of special grades.

Properties

Feature

• High accuracy of dimensions and shapes for a wide range of finishing work
• Cross-hatching finish result for high abrasion resistance and lubrication
• Fewer affected layers
• No dressing needed for efficient work

Feature

• There are various types of molds, such as press molds, die-cast molds, and plastic molds, and the final step in the mold manufacturing process is the polishing process.
• Molds are created by shaping with milling and electrical discharge machining, refining shapes with files and mounted grinding stones, removing surface scratches and unevenness with coarse-grit stick stones (mold stones), and gradually increasing the grit size for polishing.

Feature

• Super Finish Stones are divided into two types: one is used by rotating the wheel and the other is used by vibrating the wheel.
• As the name suggests, super-finishing wheels are designed for final finishing, mirror-finishing, and precision polishing.
• This method of surface finishing is performed by pouring grinding fluid.
  

Applications of Superfinishing Stones

• ① The outer circumference of rollers incorporated into cylindrical roller bearings
• ② The sliding surfaces in contact with the rollers on the outer and inner rings of bearings
• ③ The outer circumference of engine camshafts

Purpose For Superfinish

• Improvement of surface roughness
• Improvement of wear and abrasion resistance
• Reducing frictional resistance
• Improvement of contact interval
• Removal of chatter marks and spiral marks
• Noise reduction in rotor and sliding area
• Load diffusing
• Improvement of electric and magnetic characteristic
• Improvement of adherability of plating, coating and vapor deposition
• Prevention of seal abrasion
• Improvement of quality level by mirror finish

Feature

• The grain size is equivalent to medium #280, fine #600, and extra fine #1000.
• The bond is a vitrified clay-like material impregnated with solid oil, and the extremely high degree of bonding (HRH100-115) makes this whetstone less likely to lose its shape.
• Whetstone dimensions can be made in any shape, from 4-inch and 6-inch square whetstones to comb-shaped, square, triangular, and round sticks.
• Specifications include deburring, chamfering, surface correction and finishing of molds, and more (a wide range of uses).
• Since it has been oil-treated, it feels smooth even when used as is, and if it is used with a little grinding oil, the work efficiency will improve even more, and will achieve a higher precision finish than conventional oil whetstones.
• Because it is a flammable solid, be sure to dry the whetstone naturally. It may cause a fire.
