Applications
・This diamond wheel is designed as to meet various glass substrate specifications for FPD.
・This metal bond wheel is suitable for edge grinding on TFT glass and PDP (Plasma Display Panel).
・This resin bond wheel is suitable for chamfering electrode section of LCD panels and finish edge grinding.
Features & Benefits
■ Due to our advanced technology, this grinding wheel for LCD panel offers consistent quality.
■ This wheel offers high productivity and cost reduction.
■ Due to specially designed and advanced bond, this wheel can achieve longer profile holding and less chipping at high feed rate.
Applications
・This wheel is suitable for edge grinding on silicon and other material’s wafers.
・Metal bond wheel is mainly used for rough grinding to get accurate edge profile.
・Resin bond wheel is mainly used for finish grinding to get good surface roughness.
・Wheel size and specification for various kinds of edge grinding machineries are available.
Features & Benefits
In edge grinding tighter profile tolerance and finer surface roughness are required, these wheels would satisfy these needs.
These wheels used advanced bond system are produced under high quality control system and high production technology.
These wheels specially designed with uniform structure offer high stock removal rate for wafers.
Diamond section of resin bond wheels and notched wheels do not contain the metallic materials caused to contamination.
Applications
・Rough and semi-finish grinding of soft materials without loading.
・Grinding of soft metals such as aluminum alloy, etc.
・Grinding of plastic
・Grinding of rubber
・Deburring and fettling of cast.
Features & Benefits
■ One-layered superabrasives (diamond) are brazed on steel core by metal bond.
■ Due to its strong abrasives holding strength, this wheel offers large protrusion height of abrasives, which contributes to high metal removal rate for soft metal materials without loading.
■ Abrasive density can be changed depending on various types of workpieces and applications.
Applications
・Automobile parts
・Oil pump parts (Sintered metal)
・Compressor parts (Cylinder)
・Ceramic parts
・Tungsten carbide
・Miscellaneous
Features & Benefits
■ Due to our advanced bond system, this wheel can easily true the flatness of a grinding wheel with on-machine electro discharge truing, and also this wheel can reduce the amount of dimensional compensation during grinding, so that high accuracy in workpiece quality and longer wheel life can be offered.
Case history
■ Grinding conditions
・Grinding machine : KVD-300S Ⅱ KOYO Machine Industries Co., Ltd.
・Grinding mode : Infeed oscillation
・Wheel size : 305D × 50T × 80H × 75W
・Wheel specifications : SD325N50MX151
・Workpiece material : Sintered metal (Oil pump gear)
・Wheel speed : 24m/s（1500min‐¹）
・Stock removal : 0.25mm/ both side
■ Results
The height of burrs was reduced to half.
There was hardly any size variation at an early stage, and stable grinding was achieved.
