For Turbine Blades Grooves / High Precision Electroplated Wheel CB Master
Highly Efficient Processing of Heat-Resistant Alloys Works very well in deep groove form grinding of heat-resistant alloys that requires a high level of profile accuracy. Compared with general grinding wheels, consistent highly efficient processing with no dressing is available. ・High peripheral speed wheel of special design by employing a highly rigid steel body offers highly efficient processing. ・Firm super-abrasive grain layer created by "precision electrodeposition technology" for longer service life. ・Profile accuracy is maintained until the tool life comes, and grinding consistency is sustained. ■Features ・Form grinding of groove to secure heat-resistant alloy turbine blade mounting part ■Applications
Turbines, Other Heat Resistant Alloy Processing/ Electroplated Wheel CB Master
・The combination of a steel body and a strong super abrasive layer realizes gross form machining at high peripheral speed, improving machining efficiency and extending tool life. ・Improves surface finish and shape accuracy compared to cutting. ・Electroplated wheel eliminates the need for dressing and drastically reduces setup time for profile grinding. ■Features ・Forming of shrouds and other parts of turbine blades for aircraft engines ・Blade grooving of gas turbine for power generation ・Balancing process of impellers for turbochargers ■Applications Optimized for Form Grinding of Heat-Resistant Alloy Parts Special superabrasive layer with high sharpness suppresses grinding resistance and reduces the formation of burrs and work deformation layers required for heat-resistant alloy parts. □Comparison of Heat-Resistant Alloy Processing with Conventional Electroplated Wheels Grinding Center ①CB Master #80 ②Conventional Electroplated Wheel #80 φ50-10W Straight Water-Soluble Wheel Peripheral Speed : 40 m/sec D.O.C. : 0.05 mm Feed Rate : 200 mm/min ■Machining Examples 1）Machine 2）Wheel Specification 3）Wheel shape 4）Coolant 5）Conditions

For Combustor Casing / High Precision Electroplated Wheel CB Master
Process Integration and Automated Operation Newly developed CB Master specially designed for semi-finish grinding of large heat-resistant components. Internal coolant supply available optionally. ・Semi-finishing of flanges of heat-resistant alloy combustor casing ■Applications ・Corners to which sufficient coolant cannot be supplied by the external oil supply system can be protected from formation of damaged layer by wheel internal supply system. ・Mountable on 5-axis compound machines. Process integration and automated operation. ・Surface roughness unachievable by cutting is realized. Since there are no cut marks, hand finishing work in the following process can be reduced. ■Features
