Modulhard'Andrea MHD'
It is a line of high precision modular tool-holders used to perform with extreme flexibility and rigidity operations of boring, milling, drilling and tapping.
The MHD coupling is the strength of the Modulhard’andrea:
it is available in eleven sizes; it guarantees the interchangeability of all system elements, which includes arbors, extensions, reductions and tool-holder adapters.
The broad boring program completes the MHD line with a wide range of double-bit roughing heads and digital, micrometric and centesimal finishing heads.
BASE CONNECTIONS - EXTENSIONS - REDUCTIONS
BASE CONNECTIONS Made according to the DIN 69871, MAS 403 BT, DIN 2080, ANSI-CAT, DIN 69893 and ISO 26623-1 standards and built in carburized, hardened and ground steel 8000 RPM BALANCING.
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 optimising the composition of the tool according to the overall dimensions.
RAV Anti-vibration reductions for deep or heavy-duty machining.
ROUGHING HEADS TS
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.
With two SSCC bit holders aligned and on the same diameter for roughing operations with high feedrate.
With one SSCC bit holder and one SMCC bit holder staggered and on a different diameter for roughing operations with high depth of cut.
With only one bit holder for light roughing or semi-finishing operations. PT plate assembly required to protect the coupling surface.
DOUBLE-BIT HEADS TRD
The TRD double-bit heads allow combined roughing and finishing machining with IT7 precision.
The serrated surfaces between the bit holders and the tool holder slide guarantee rigidity and the adjustment sensitivity of 5 microns on the radius is easily readable on the vernier scale and can also be performed on the machine.
MICROMETRIC HEADS TRM
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 TRM are coated with an anticorrosive surface protection.
CENTESIMAL HEADS TRC
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.
DIGITAL HEADS TRE
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 are coated with an anticorrosive surface protection and are resistant to liquid contamination according to the IP69K grade of protection.
DOUBLE-BIT CROSS BARS BPS
The BPS bars cover a working range from Ø 200 to Ø 1200 mm, both in roughing and in finishing.
The wide range of accessories includes both roughing bit holders and micrometric finishing heads capable of performing boring, chamfering and back-facing operations.
The main body of the BPS bars is made of aluminium on which the bit holder plates are fixed.
TESTAROSSA KIT
The TESTAROSSA KIT are supplied in a box with a wide range of tool holders, tools, inserts, and service spanners.
