D'ANDREA® Boring Tools & Facing Heads

ACC Tooling & Repair, Inc. is a premier provider of D'ANDREA precision tooling products, from AUTORADIAL automatic facing heads to the U-TRONIC large sized boring and facing heads that allow turning operations on fixed pieces. We offer the full D'ANDREA product line, so call us directly to ask about any item not listed.


AUTORADIAL

The AUTORADIAL offers a range of facing heads featuring automatic working feed and rapid return of the tool slide. It does not stop or reverse the spindle of the machine tool, only when resetting for the next working cycle.

Three Models With No Electronic Interface

AUTORADIAL heads are applicable on machining centers and on NC machines, without the need for any electronic interface. They automatically execute a working cycle of advance and return. The machine spindle must be reversed to reset the head for the next operation. The heads are produced in three models, AR100, AR125, and AR160, and are supplied with one feed rate gear module. Six different and interchangeable feeds are available.

MHD Modular Tooling System

The Modular (MHD) tooling system utilizes D’Andrea’s patented cylindrical - conical joint with a radial expanding pin to create an extremely rigid concentric connection between components. D’Andrea’s MHD system offers a high degree of flexibility and simplicity suitable for milling machines, machining centers, and flexible machining systems.

An essential element of the MHD system is a complete line of rough boring and extremely accurate (2µ) fine boring heads.

Features

  • Boring, Milling, Drilling and Tapping
  • Through Coolant
  • Boring Diameters from 4mm to 500mm
  • D'Andrea Boring Kits
MHD Modular Tooling System MHD Modular Tooling System - Milling

modulhard'andrea 

MODULHARD'ANDREA - MHD is a high precision modular tooling system for the operations of boring, milling, drilling, tapping and profiling. 
Rigidity, concentricity, quality, precision, and flexibility are guaranteed by the coupling system which consists of a cylindrical-conical joint, that when joined together automatically centralizes. A slight deformation occurs during lock-down and produces the strongest joint in the industry.
MHD tooling system includes:

  • Arbors in accordance with DIN — ISO — HSK — BT — CAT Standards
  • Extensions and Reducers 
  • Vibration Dampening 
  • Adaptors: Weldon/Whistle-Notch holders, milling cutter holders, tapping chucks, morse taper holders, coolant chucking tools and semi-finished cartridges for special applications.
  • Roughing double-bit boring bars provide a working range between 18mm and 500 mm diameter.
  • Finishing TRM D’Andrea heads and micrometric boring bars for bores from 2.5mm to 500 mm diameter.
  • Balanceable TRM D’Andrea heads and balancing rings for high-speed machining up to 20,000 rpm.
TRM50 - Finish Boring

MHD MODULAR TOOL HOLDER SYSTEM is available in eight different sizes to guarantee the full interchangeability of all components to perform various tasks.

A wide range of extensions and reducers are available in different lengths enabling the assembly of various components to perform various tasks.

Wintool, a tooling software is available to aid in the development of tools for the tool crib or tool designer that provides a breakdown of all components.

U-TRONIC

U-TRONIC offers a wide range of medium and large servo-controlled heads for machining centers and specialized machines. Controlled by the U axis of the CNC, the U-TRONIC can perform facing and back-facing, cylindrical and conical boring, threading, concave and convex radius machining, and complex profiles, by the interpolation of the other machine axes.

D’Andrea’s U-TRONIC offers a wide range of medium and large servo controlled heads for machining centers and specialized machines. Controlled by the U axis of the CNC, the U-TRONIC can perform facing and back-facing, cylindrical and conical boring, threading, concave and convex radius machining, and complex profiles, by the interpolation of the other machine axes. These heads can be fitted manually, automatically or through palletized systems, on boring machines and specialized machines.

D’Andrea offers six standard models, between 360 mm and 1000 mm diameter, all of them with internal coolant supply.
Also, U-TRONIC heads are supplied in special duel slide versions or with counterweights for tool slide balancing and high-speed.
