STAV-40 Diamond smoothing tool for antivibration boring bars SANDVIK, SECO, ISCAR, AKKO, KENNAMETAL is used for finishing and strengthening of internal surfaces of parts.
It is used on universal lathes and CNC lathes with increased turning centers.
Version with adjustable smoothing force, for machining of various parts.
Shape of workpiece - cylinder, body of rotation, cone, groove.
Minimum diameter of machined hole : 63 mm
Depth of the hole to be machined : determined by the length of the boring bar.
Natural diamond (PA) indenters are used The tool is used for finishing smoothing.
Diamond smoothing (AB) and the tool 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 UPON PAYMENT OF THE INVOICE !!!!
WARNING !!! The tool is not used for smoothing Titanium, Niobium, Zirconium materials due to the high toughness 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 chrome.
Mirror finishing rolling tools
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 50...150 microns.
Optimization of the surface microrelief will additionally increase die durability indenter radius.
