Wire Drawing
・Because the area of acting diamonds stays constant, it maintains stable dressing performance. ・Optimum dress performance can be obtained by adjusting the size of diamonds and the number of arrays. ■Features ・Used for traverse dressing of general grinding wheels and CBN wheels used for internal grinding of various bearings, Automotive and machine parts, etc. ■Applications Consistent Dressing Performance These dressers are manufactured by holding prismatic diamonds in arrays on a metal base with sintered metal. Because carefully selected prismatic diamonds are used, the area of diamonds acting on the wheel surface stays constant, maintaining the consistent dressing performance. Moreover, the most suitable dressing performance can be obtained by adjusting the size of diamonds and the number of arrays.
BLPCD Dies
Excellent Wearing Resistance, No Crystal Orientation Like Single Crystal Diamond 100% nano-polycrystalline diamond "BLPCD" which diamond particles are strongly bonded and does not contain a binder. It has higher hardness than single-crystal diamond and no anisotropy, so it provide excellent wear resistance and roundness retention. Since it does not contain binder, it hardly causes scratches on the wire surface brought up by falling off of diamond, binder particles or contamination and it maintains excellent wire surface roughness. The applicable range is from ultra-thin wire of 0.008 mm to around 1.0 mm. *For 0.010 mm or smaller diameter, please contact us. ・Wire Materials Soft Wire Materials: Copper wire, Aluminum wire, Brass wire, etc. Hard Wire Materials: Stainless steel wire, Brass plated steel wire, Galvanized steel wire, Copper plated steel wire ■Applications ・Excel in Maintaining Roundness ・Wear resistance is more than 3 times compared to single crystal diamond ・Realize good surface roughness equivalent to single crystal diamond ■Features

Consistent Dressing Performance This dresser is manufactured by holding CVD thick film prismatic diamonds in arrays on a metal base with plated metal. The CVD thick film prismatic diamond has no anisotropy and the area of diamonds acting on the wheel surface stays constant, maintaining the consistent dressing performance. Moreover, the most suitable dressing performance can be obtained by changing the size of diamonds and the number of arrays.
・CVD diamond provides high-wear-proof performance like single crystal diamond. ・Constant and stable active area with prism diamond. ・Cost effective with no reworking. ■Features ・Used for traverse dressing of general grinding wheels and CBN wheels used for internal grinding of various bearings, automotive and machine parts, etc. ■Applications ■Standard Manufacturable Range Straight Type Cup Type
