By using diamond for water jet nozzle, water stream width can be minimized and directness and ultrahigh pressure achieved, resulting in higher precision and longer life. Furthermore, by expanding the width of the water stream, the nozzle can also be used for cleaning and removal of burrs.

The accuracy of the wire guides determines the precision of wire electrical discharge machining(EDM), which is used for metal forming processes in various industries. Asahi Diamond has developed this highly functional diamond wire guide jointly with an electrical discharge machining equipment manufacturer.

Lace centers (concave/convex): Sampax is used on the tips of concave/convex centers that support workpieces on lathes and grinders to achieve long-term, high-precision machining.
Centerless blades: SUNPAX is used in the blade wear area of centerless grinding machines to achieve high-precision, high-efficiency machining.
Shoes and rests: Wear resistance is especially required for the parts that hold the workpiece in place on the grinding machine. The use of "Sampax" for this purpose makes it possible to maintain high machining accuracy.
Measuring tools: When measuring the dimensions of machined parts, the use of diamonds or Sampax on the tips of measuring tools provides resistance to abrasion and helps maintain measurement accuracy.

Vitrified grinding wheel using general abrasive grains. A wide variety of wheel configurations from soft to hard are possible, and they are effective as dressing materials for metal tools.

Vitrified bonded grinding wheel using cubic boron nitride abrasive grains. They are highly evaluated for grinding ultra-precision parts with super-finished bearing raceway surfaces. In addition to standard CBN wheels. we offer a broad lineup of CBD wheels, which emphasize sharpness, and DBN wheels, which emphasize surface finish accuracy, allowing us to design wheels that meet your needs.

Grinding wheels for final finishing of metal products. Suitable for super-finishing of raceway surfaces of various bearings and for super-finishing of outer diameters of needles, rollers, etc.

New dress drive unit with compact, high-rigidity, high-output spindle a high-sensitivity AE sensor is built in to check the forming condition of the grinding wheel with high accuracy.

SUNPAX：Sintered Diamond SUNPAX：Polycrystalline Diamond (PCD)
A polycrystalline sintered body obtained by simultaneously forming microcrystals of synthetic diamond with various bonding agents at high temperature and high pressure. Mainly used as high-precision cutting and wear-resistant tools for nonferrous metals, non-metals, and composite materials.
SUNNITE: Cubic Boron Nitride Sintered SUNNITE: Polycrystallite Cubic Boron Nitride (PCBN)
A polycrystalline sintered body obtained by forming microcrystals of CBN at the same time as the binder at high temperature and high pressure. It is mainly suited for cutting difficult-to-cut materials such as hardened steel and heat-resistant steel.

Diamond powder is used as an abrasive (loose abrasive) or fixed with a metal bond, resin bond, vitrified bond, or other bonding material for grinding and polishing.

Natural diamonds are produced in a limited number of regions due to the conditions under which they are produced. Rough diamonds are used for wire drawing dies, bites, dressers, etc., depending on the application.
