Universal rotary diamond burnishing tool ST21-Ø20 is used for finishing and hardening of workpiece surfaces in hard-to-reach areas of parts, radii, cones, ends, holes, hemispheres, depressions, external surfaces.
Used on conventional lathes and CNC machines. Version with adjustable smoothing force, for machining of various parts. Shape of workpiece - cylinder, bodies of rotation, cone, groove. Diameter of the workpiece from 6mm. Metric Holder 20 mm, Minimum diameter of machined hole : 40 mm Depth of machined hole : 150 mm
Natural diamond (PA) indenters are used The tool is used for finishing smoothing. Diamond burnishing (AB) and Tooling completely replaces the grinding and polishing area. The cost of personnel, grinding machines, consumables is reduced, and no re-setting of parts or re-basing is required. The machining process smooths roughness to Ra = 0.2.....0.05 µm in one or two passes It is used on CNC machines, on universal lathes. To obtain a stable micro-profile of the surface without waves, it is recommended to use ST-21 on machines that can provide finishing turning! Machining materials: any structural steel with hardness max HRc 65 Roughness before machining not more than Ra = 1.25 microns. Example of parts - hydraulic cylinder rods, gate valve spindle, submersible pump heel, shaft, shaft surfaces for bearings.
STANDARD MACHINING MODES ARE AVAILABLE AFTER PAYMENT OF THE INVOICE !!!
The tool is not used for burnishing Titanium, Niobium, Zirconium materials due to the high toughness of the material!!!!
The quality of chrome plating can be improved by diamond burnishing of its surface. This treatment seals the surface layer and eliminates seal failure of chrome plated parts caused by the presence of microcracks in the chrome.
Mirror-like metal surface.
Diamond burnishing provides the increase of the the surface hardness of dies and punches more than 1500 NV. The roughness of the tool surface is reduced to Ra 0.1 microns. The depth of the hardened layer is 50...150 microns. Optimization of surface microrelief will additionally increase die wear resistance.
Main purpose: burnishing of surfaces of products made of ferrous and non-ferrous metals and their alloys, except for hard alloys and titanium. They provide hardening of the machined surface and obtaining Ra up to 0,20÷0,02 microns. Diamond burnishing of the surface layer of machine parts. Strengthening by surface plastic deformation.
