“SOLOTERU” Metal Grinding Wheel with Uniform Distribution of Abrasive Grains
The use of a technique for ensuring an even distribution of abrasive grains within the abrasive layer delivers improved cutting performance together with long life compared to the metal tools traditionally used for machining precision components and mechanical parts made from ceramics and similar materials. The superiority to other tools also includes enhanced cutting performance when machining hard brittle materials and other special materials thanks to the ultra-thin cutting edge of the abrasive layer, with benefits that include minimizing the cutting load and reducing chipping.
A single-pointed dresser mounted with a synthetic mono-crystalline diamond on the tip and with a cutting edge produced through grinding. Offers a more stable dressing performance compared to natural diamond dressers. The cutting edge can be replaced with pyramid-shaped and cone-shaped types, allowing work to be performed under the same dressing conditions as natural diamond dressers.
A diamond dresser has one or more diamonds mounted on the tip of its shank and is used for truing and dressing grinding wheels. The efficiency of grinding and finishing depends on the quality of the dresser. Asahi Diamond manufactures a broad range of diamond dressers, including:
Blade dressersBond dressers
Roller Dresser Type
PRISMA DRESSER improve’s tool life and dress quality by using polycrystalline diamond, proven to be more durable than mono-crystal synthetic diamond which is prone to cracking and shorter tool life.
Consistent diamond wear is due to consistent cross sectional area through length of the polycrystalline diamond, making it very suitable for automated dressing operations.
Various polycrystalline diamond dimensions are available to meet specific needs of each application and customer.
Polycrystalline diamond provides consistent dresser performance and ability through out the tool so no need to orient the diamond.
SUNPAX reamers are made with focus on stable quality, based on control over reamers’ key properties such as the outside diameter and run-out tolerance, using our advanced processing technologies. We can also design them to meet high-precision demands for surface finish, circularity, and coaxiality and allow rapid feeding. We satisfy your needs with our extensive product lineup from specifications to additional value types.
Thrust can be significantly reduced by switching from a conventional straight edge reamer to a helical reamer, and it allows rapid feeding and contributes to higher productivity.
We design edges for your needs to improve the efficiency of various types of processing such as milling, grooving, spot facing, and curve facing. It is also possible to make spiral types for high-speed cutting, high-precision ball shapes, and taps. Applications include high-precision and high-efficiency processing of metal molds, compressors, FRP, acrylic, and so on.
To meet the market demand for high productivity, we developed helical type drills with a diamond compact, which allows rapid feeding and reduces thrust. Also available are special types that solve exit burr and chip obstruction problems. They also allow you to integrate processes by adopting one-pass finish and multistep edges.
As a solution to chip obstruction, one of the problems in cutting, we specially treated the edge to cut chips much smaller and therefore you can avoid such troubles as chips coiling around and remaining in the workpiece.
Replacing iron and cemented carbide with diamond extends the service life of wear parts and helps reduce running costs.
・Centerless Blades (Work-Rest): SUNPAX also greatly improves accuracy and efficiency at the work-rest of a centerless grinding machine.
・Shoe & Rest: The shoe and rest are used for fixing workpieces on a grinding machine. SUNPAX used for the shoe and rest increases their accuracy and durability.
・Gauge Heads: Diamond or SUNPAX applied to gauge heads for measuring the dimensions of machined parts reduces wear and improves measuring accuracy due to its durability.
As a solution for special tooling, a tooling holder and a reamer are integrated, making it possible to shorten the length and increase the rigidity of the tool and therefore meet high precision demands. We can also manufacture these according to various holder standards.
SUNCREA realizes sharpness and service life which could not be obtained with conventional metal bonds in sapphire, carbide, hard brittle materials such as ceramics and ferrite, hard magnetic materials such as neodymium iron, iron-based materials such as sintered parts, contributing to processing efficiency improvement and cost reduction.

With excellent shape-maintaining performance, the wheel adapts for low-to-high horsepower grinding machines (excluding those for dry grinding). Truing and dressing of the wheel are as easy as those with a resin bond wheel.
“AERO METAL” Super-Porous Metal Bond Wheels
AERO METAL provides significantly improved cutability compared to past metal bonds due to its porous structure (with open pores) that uses a metallic bonding material, providing easier circulation of grinding fluid and being less prone to shedding chips. It can satisfy a wide range of requirements, from ease of cutting to long life, with the chemical bond between the bond and abrasive grains helping retain these grains.
