ST21-32-300 UNIVERSAL ROTARY DIAMOND BURNISHING TOOL FOR VERTICAL TURNING LATHE MACHINE

Universal Rotary Diamond Burnishing Tool ST-21-32-300 is used for finishing and hardening of workpiece surfaces in hard-to-reach areas of parts, radii, cones, ends, holes, hemispheres, depressions, external surfaces.

It is used on conventional heavy lathes, turning machines and CNC machines with increased center-to-center distance.

Version with adjustable burnishing force, for machining various parts.

The shape of workpiece is a cylinder, a body of rotation, a cone, a groove.

The diameter of workpiece is from 6mm.

The metric Holder is 32x25.

The Inch Holder is 1.5" x1.00"

The minimum diameter of the hole to be machined is 63 mm.

Working depth 230 mm.

Natural diamond indenters (PA) are used. The tool is used for finishing burnishing.

Diamond burnishing (AB) and the Tool completely replace the grinding and polishing area.

Personnel costs, grinding machines, and consumables are reduced, and parts re-setting and re-basing are not required.

During machining, the roughness is burnished to Ra = 0.2.....0.05 microns in one or two passes.

It is used on CNC machines, on conventional lathes.

To obtain a stable surface wave-free micro-profile, it is recommended to use ST-21 on machines that can provide fine turning!

Machining materials: any structural steels with a hardness of max HRC65.

The roughness before machining is no more than Ra = 1.25 microns.

An example of parts: the rods of hydraulic cylinders, the valve spindle, the heel of the submersible pump, the shaft, the shaft surfaces for bearings.

STANDARD MACHINING ARE PROVIDED AFTER PAYMENT OF THE INVOICE!!

Burnishing tip, diamond burnishing tip, micro-burnishing, hardening, roller burnishing, diamond burnishing (AB).

ATTENTION!!!

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 finishing rolling tools.

Mirror-like metal surface.

Diamond burnishing makes it possible to increase the surface hardness of dies and punches by 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 the micro-profile of the surface will further increase the wear resistance of die indenter radius.
