Diamond burnishing tool ST-5

for hardened steel

Diamond burnishing and hardening tool Sensor-Tool ST-5 The tool is used for finishing surface treatment of steel, stainless steel, cast iron, alloys workparts Workpart shapes - cylinder, body of rotation, plain body, spherical part The tool is used for finishing, finishing and strengthening and nanostructuring burnishing operations You can reset the loading for other technical processes using a dynamometric device (purchased separately), or we can adjust loading for your single workpiece. High-precision diamond tools. The tool completely replaces the grinding and polishing area. At finishing and finishing-hardening processing, smoothing of roughness is provided up to Ra = 0.2 ... 0.05 micron; for nanostructuring burnishing - up to Ra = 0.32 ... 0.12 microns. Hardening of the surface layer is provided 1.3 ... 2 times relative to the initial state. It is used on CNC machines and universal machines capable of finishing turning. A machine is required with the possibility of supplying the coolant heating circuit under pressure> 10 Bar through the central hole in the holder. Hardening of the material in the thin surface layer of steels is carried out by forming a nanocrystalline structure with grain sizes less than 100 nm. By controlling the friction force of the tool indenter and the development of intense plastic shear deformation. During dry machining of submersible oil pump heel, a nanostructured layer with thickness of 8...12 µm is formed from structural cemented steel 20X (HRC 55...65) by means of ST 5 type tool with indenter with microhardness up to HV0.025 1500...1600 (after finishing turning HV0.025 825...845).
