Universal rotary diamond smoothing machine ST-21 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 universal 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 holders 16x16, 20x20, 25x25, 32x25 (and also according to customer's dimensions). Inch holders 0.750 "x0.750" 1.00 "x1.00" Minimum diameter of the hole to be machined : 65 mm Working depth : 120 mm Natural diamond (PA) indenters are used The tool is used for finishing smoothing. Diamond smoothing (AB) and Tooling completely replaces the grinding and polishing area. The cost of personnel, grinding machines, consumable tools 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 !!! Smoothing tip, diamond smoothing tip, micro smoothing, hardening, rolling polishing, diamond smoothing (AB). WARNING !!! The tool is not used for smoothing Titanium, Niobium, Zirconium materials due to the high viscosity of the material !!!!
The quality of chrome plating can be improved by diamond smoothing of its surface. This treatment seals the surface layer and eliminates tight joints of chrome plated parts due to the presence of microcracks in the chrome. Mirror metal surface Diamond smoothing allows to increase the surface hardness of dies and punches more than 1500 NV. The roughness of the tool surface is reduced to Ra 0.1 µm. The depth of the hardened layer is 200...250 microns. Optimization of the surface microrelief will additionally increase die durability. indenter radius
