U-Tronic Programmable Head

Features and Benefits

  • Medium and large sized NC boring and facing heads for boring machines, machining centers, and special machinery, which are applied manually, automatically, and with palletized systems on boring machines, machining centers, and special machinery

General Features

  • U-TRONIC are medium and large sized NC heads that are connected to the U axis of the NC in the machine tool for outer facing, inner facing, back-facing, cylindrical and conical boring and threading, concave and convex corner rounding through interpolation with the other axes of the machine tool
  • They can be applied manually or automatically and with pallet systems on boring machines, machining centers and special machines
  • They are constructed in 6 models from ø 360 to ø 1000 mm. All these include an internal passage for coolant. Special versions of U-TRONIC, with two slides or with counterweights for self-balancing, may be supplied upon request
  • Fixed toolholders may be applied to the slide, with either manual or automatic tool change
  • Any application on machines that do not permit the connection to an axis of the NC, may be made by managing the motor of the drive unit with a practical, simple, and economical U-CONTROL positioner with wireless REMOTE-CONTROL


  • There are two types of controls for U-TRONIC heads: The first involves a direct connection to the “U” axis of the NC of the machine tool and allows for all types of cylindrical and conical boring, facing, threading, corner rounding and spherical operations to be performed. The second involves the use of a simple U - CONTROL positioner with wireless REMOTE, which can be connected to the M functions of the machine to receive start signals of the different operations programmed on the REMOTE - CONTROL.This solution allows all types of turning, boring, facing, internal, external, threading, and conical operations to be performed but spherical operations
  • U-TRONIC heads are equipped with SIEMENS 1FT6 motors (other motors available upon request), removable female connectors and limit switch unit; ENCODER upon requested

Coolant Supply

  • The U-TRONIC heads are arranged with holes for the passage of the coolant, which pass through the rotating body
  • From additional holes on the fixed body, it is possible to enter air to pressurize the motor and limit switches area, to automatically lubricate with grease the internal mechanism and lubricate with spayed oil the sliding guides of the slide and the leadscrew


  • To improve working conditions and balance the position of the tool when it appears shifted in relation to the U-TRONIC axis, counterweights can be applied using the threaded holes located on the rotating body


  • U-TRONIC is applied manually or automatically using a flange for fastening to the machine tool and a plate for the rotation of the rotating body
  • It is applied manually using a flange for fastening with a cam lock quick coupling, or automatically with a palletized system and special connectors
  • U-TRONIC can also be fitted with an automatic tool change toolholder mounted on the slide to obtain total automation
