Diamond burnishing tool ST21-20M

Universal rotary diamond burnishing tool ST21-20M is used for finishing finishing finishing and hardening surfaces of parts in hard-to-reach areas of parts, radii, cones, ends, holes, hemispheres, hollows, outer surfaces, bottoms and radii at bottoms. Version with adjustable burnishing force, for processing various parts. Workpiece shape - cylinder, bodies of rotation, cone, fillet, bottom Minimum Diameter of processed workpiece 6mm. Metric tool holder 20*20 3/4" inch holder Minimal diameter of the work hole : 63mm Depth of the work hole : 230 mm Natural diamond (PA) indenters are used The tool is used for dressing. Diamond Capping (AB) and the Tool completely replace the grinding and polishing area. Costs for personnel, grinders, consumable tools are reduced, no re-setting of parts and no re-basing is required. Roughness is smoothed to the level of Ra = 0.2.....0.05 μm in one or two passes It is used on CNC machines, on universal lathes. To obtain a stable surface micro-profile without waves it is recommended to use ST-21 on machines that can provide finishing turning! Materials of machining: any structural steel with a hardness of max. HRc 65 Surface roughness before machining not more than Ra = 1.25 µm Example of details - stems of hydraulic cylinders, slide valve stem, pump heel, shaft, shaft surface under bearings. STANDARD PROCESSING MODES ARE AVAILABLE AFTER PAYMENT OF THE INVOICE! Smoothing tip, diamond trowel, micro-smoothing, hardening, rolling polishing, diamond trowel (AB) WARNING Tool is not used for smoothing of materials Titanium, Niobium, Zirconium because of the high viscosity of the material!!!
