The tool is used for making a nanostructured layer on the surface of steel, stainless steel, cast iron, alloys workpieces by intense plastic shear deformation. This is ensured by the special design of the holder with heat sink for the indentor.
Workpiece shapes - cylinder, body of rotation, plain body.
Workpiece diameter starting from diamter 10 mm.
Toolholders with round shafts diameters 20, 25, 32 (can be customized).
The tool is used for finishing, hardening and nanostructuring burnishing.
You can reset the loading for other technical processes using a dynamometric device (purchased separately), or we can adjust loading for your single workpiece.
The tool completely replaces the grinding and polishing area.
Finishing and hardening achived roughness up to Ra = 0.05 um;
Nanostructuring burnishing achived roughnes up to Ra = 0.05 um.
Microhardness of the surface layer is 1.3 ... 2 times higher than initial state.
The tool is used on CNC machines and conventional machines capable of finishing turning.
A machine providing the possibility of supplying coolant under pressure > 10 Bar through the central hole in the holder is required.

Mirror-like metal surface
ATTENTION!!!
The tool is not used for burnishing Titanium, Niobium, Zirconium materials due to the high toughness of the material!!
Nanostructured surface properties.
Very good bone growth to the nanostructured material.
Nanostructuring gives very high hardness combined with increased elasticity.
The hardness of the file and the elasticity of the rubber.
The elasticity is ensured by the fine grain. The surface treated with ST-4, ST-5 performs well in tribocouplings, takes the shape of the recipient part.
It is not brittle like other superhard coatings.
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 indentor and the development of intense plastic shear deformation.
While dry machining of the ubmersible 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 indentor with microhardness up to HV0.025 1500...1600 (after finishing turning HV0.025 825...845).
Hit indentation hardness reaches 13 GPa, which is comparable to the hardness of coatings.
Residual stresses reach 1950 MPa and a microprofile with Ra = 3.2...60 nm is formed.
To maintain the allowable contact temperature and increase tool life, the indentor is cooled by the turbulent flow of the machine's coolant.
Nanostructural surface hardening of submersible pump heel type parts provides 3.2 times reduction of surface wear intensity in abrasive environment conditions
Under low-cycle loading conditions the samples processed by nanostructural surface hardening have a multiple margin of fatigue resistance in comparison with the samples processed by smoothing and grinding. Due to the formation of nanocrystalline structures in a thin surface layer up to 10 microns and the creation of a high level of strength and plasticity of the surface layer.
The quality of chrome coating can be improved by diamond smoothing its surface. This treatment seals the surface layer and eliminates violations of the tightness of the tight links of chrome parts due to the presence of micro cracks in the chrome.
Tools and accessories for machine tools and machines for chipless metal working. Metal surface superfinish.
Diamond smoothing allows increasing the surface hardness of matrixes and punches over 1500 N". Roughness of the tool surface is reduced to Ra 0.1 μm. The depth of the hardened layer is 200...250 µm. Optimization of surface micro-relief will allow further increase of dies resistance.
