General

The CrossMaster DD is equipped with two disc units, one for deburring and one for edge rounding. The workpieces are placed on a high-friction feed belt. The disc tools, which are parallel to the workpiece, push the workpiece against the feed belt during operation. As a result, it is possible – on a disc-only machine – to process even very small workpieces starting from 20 x 20 mm.

There are two models to choose from:

CrossMaster DD 300S: Heavy-duty model with 300 mm working width with a wide range of options.

CrossMaster DD 200 Mini: Compact model with 200 mm working width, well equipped as standard, without further options, but at a very good price.

  • Two rotating discs in a row
  • Disc diameter larger than conveyor belt width, processing from two directions
  • Uniform tool wear regardless of the position of the workpiece on the conveyor belt
  • Simple and quick tool change for material mix, as only 2 tools need to be changed
  • Versatile application options due to the large variety of available tools
  • Low investment, tool and operating costs

The CrossMaster DD 300S is the heavier version, with a working width of 300 mm. Depending on requirements, the machine can be equipped and customised with various options.

The CrossMaster DD 200 Mini is a compact machine with a working width of 200 mm. Due to its compact size, it can easily be used without a workpiece return conveyor. The machine is well equipped as standard, with motorized thickness adjustment, digital display, inverters and a feed belt cleaning brush. Use the CrossMaster DD 200 Mini as an additional machine for processing small parts faster, with less energy and without the risk of damaging a larger machine with small parts.

Possibilities

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

Technical Data

  • Max. working width: 200 mm or 300 mm
  • Shortest workpiece length: 20 mm
  • Sheet thickness: 0.3 mm – 80 mm

Options

Rotating cleaning brush
The rotating brush cleans the conveyor belt from below on the outfeed side.

Infinitely variable disc rpm
When using different disc tools for different applications it is important to adjust the the disc rpm.

Quick-fix tool connector
The quick-fix tool connector allows for speedier changing of discs when switching between steel and stainless steel.

Magnetic track
A permanant magnetic track is located below the feed belt for holding down smaller steel parts. This is recommended especially when using OxideDiscs.

Demagnetization occurs below the feed belt on the outfeed side of the machine.

Extended feed table
for processing longer parts.

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

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

Units/Tools

LOEWER D – Rotating Disc without Oscillation

The workpiece is placed on a feed belt and passes under the rotating disc which works from the top. The disc diameter is larger than the width of the feed belt, thus allowing the workpiece to be processed from two directions, left to right and right to left.

  • Processing from two directions
  • Even wear of abrasive tools

Possible Tools

SoftDisc with soft pad for deburring mild steel or aluminium

Legally-protected CompactDisc for removing higher burrs and spatter on stainless steel

MediumDisc for edge rounding, available in different grit sizes and hardnesses.

Flexible SmartFlexDisc for edge rounding foil-coated, zinc-coated or 3D punched sheet metal parts
