Modular Toolholders MHD’

ARBORS made according to the DIN 69871, MAS 403 BT, DIN 2080, ANSI-CAT, DIN 69893 and ISO 26623 standards and manufactured in carburized steel, hardened and ground to AT3. BALANCING at 8.000 RPM.

PR For each MHD’ size there are extensions of different lengths that can be used to achieve the desired machining depths.

RD The reductions allow the use of MHD’ components of a smaller size thereby optimizing the composition of the tool according to the overall dimensions.

RAV Anti-vibration reductions for deep or heavy-duty machining.

TS Simple and extremely rigid roughing heads thanks to the serrated surfaces between the head body and the bit holders. The constant distance between the bit holder clamping screw and the cutting edge guarantees the stability of the system.

USE Roughing and semi-finishing operations.

Cutting edges might be adjusted on a pre-setting bench and TS heads can be used in three different configurations:

• two SSCC bit holders aligned and on the same diameter for roughing operations with high feedrate;
• one SSCC bit holder and one SMCC bit holder staggered and on a different diameter for roughing operations with high depth of cut;
• only one bit holder for light roughing or semi-finishing operations.

The TRM heads allow high precision machining and excellent surface finish in IT6 grade of tolerance. 

The adjustment sensitivity of 1 micron on the radius is easily readable on the vernier scale and can also be performed in the machine.

The TRC heads allow high precision machining and excellent surface finish in IT7 grade of tolerance. 

The adjustment sensitivity of 5 micron on the radius is easily readable on the vernier scale and can also be performed on the machine.

The TRE heads allow high precision machining and excellent surface finish in IT6 grade of tolerance.

The adjustment sensitivity of 1 micron on the radius is fast, accurate and is easily readable on the integrated display.

The TRE is resistant to liquid contamination according to the IP69K grade of protection.

The TESTAROSSA KITs are supplied in a box with a wide range of toolholders, tools, inserts, and service spanners and allow great flexibility for the working range.
