The DiscMaster 4TD is equipped with two deburring discs and two edge rounding discs. The discs oscillate continuously over the workpiece during throughfeed. The interaction of the rotation with the large oscillation stroke leads to high quality deburring and edge rounding results. The large variety of disc tools available makes the machine very versatile.

  • Two large discs both at infeed side and outfeed side
  • Large oscillation stroke over full width of the feed belt
  • All inside and outside edges are processed from all angles and directions
  • Even wearing of abrasive tools irrespective of the size of the workpiece or where it is placed on the conveyor belt.
  • Quick change of tools when switching between materials – only four discs need to be changed
  • Large variety of disc tools available makes the  machine very versatile


  • For deburring and edge rounding laser-cut, plasma-cut and water-cut parts
  • For deburring and edge rounding 3D punched parts
  • For edge rounding and orbital finishing in one pass
  • Processing of small parts from 20mm x 20mm
  • Processing of foil-covered or zinc-plated parts
  • Processing of steel, stainless steel and aluminium

Technical Data

  • Working widths: 1000mm, 1500mm and 2000mm
  • Smallest part size:  20mm x 20mm
  • Material thickness: 0,3mm – 70mm (100mm)

Infinitely Variable Disc Rpm
When using different disc tools for different applications it is necessary to adjust the the disc rpm.

Quick-fix Tool Connector

Magnetic Track
Permanant magnetic track below the feed belt for holding down smaller steel parts. This is recommended when using OxideDiscs or HammerDiscs.

Dust Extraction Unit
Loewer offers a range of dust extraction units for removing harmful abrasive dust. Depending on the application at hand they are available for wet or dry processing.

Aluminium Extraction Kit
Whe processing aluminium, a large amount of fine, light dust is created. Extraction hoods around the discs greatly enhance the dust extraction process.

TouchPanel Control
Coloured touch panel for setting and displaying machine parameters as well as for storing machine settings.

Conveyor Tables
When processing longer work pieces it is helpful to use conveyor tables. Löwer offers a wide range of tables in different lengths and widths. As an optional extra it is possible to link the variable feed speed to that of the machine.


LOEWER TD – Transversal Disc Unit

The discs rotate and oscillate with a stroke larger than the width of the feed belt. The workpiece is processed evenly from all angles and directions. The disc tools wear evenly, independent of the size of the workpiece or where it is placed on the feed belt.

  • 360° processing from all directions
  • Even wear of all discs

Possible Tools
