Diamond Sprue Bush is ideal for injection molding of filler-reinforced plastic materials. It has excellent wear resistance and reduces "wear progression at the nozzle touch area" that causes resin leakage problems. High quality diamond finish that exhibits low wettability more than a high hardness substance. In addition, the life is 10 times longer than that of conventional ferrous metal bushings. It also reduces waste.

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.

They are highly evaluated for polishing ultra-precision parts for super-finishing of bearing raceways. 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 precision grinding of bearings, automotive parts, home appliance parts, and other precision machine parts. We manufacture vitrified bond grinding wheels, which are ideal for precision grinding, using our own unique manufacturing process.

Our original coating technologies utilizing the chemical vapor deposition method can be applied on tools with any complicated shape while retraining both high adhesiveness to base metal and excellent wear resistance. With choice of the right type and thickness of coating depending on the application, these tools are most suitable for processing carbon, ceramics, and FRP.

One-use type for ferrous materials (no regrinding)CBN tip replacement tip "SUNNITE TWIN" for ferrous materials. It is highly economical, and the two-cornerCBN cutting tool cost can be reduced because of the two-corner CBN cutting edge.

With our processing know-how and a wide selection of diamond/CBN blanks, we offer standard and custom-made products and also special specification (chip breakers, wipers, etc.) designs to improve productivity in processing various materials (aluminum, nonferrous metals, hardened steel, cast iron, sintered metals, etc.
