General
The BeltMaster K4TD is equipped with abrasive belt unit and the 4TD unit with four large rotating discs that oscillate across the entire width of the conveyor belt. The abrasive belt is equipped with our unique tolerance sanding device. The combination of the wide belt unit and our 4TD disc concept makes this system a versatile solution for sanding, deburring, rounding, oxide layer removal or orbital finishing with one machine.
- Abrasive belt unit for sanding or deburring with infinitely variable belt speed
- Two disc units on the infeed side, two disc units on the outfeed side
- Oscillation across the entire belt width
- All inside and outside edges are processed from all angles and directions
- Uniform tool wear of the discs regardless of the placement of the workpiece on the conveyor belt
- Quick and easy tool change for material mixes
- Versatile application options thanks to the wide variety of tools available
Possibilities
- Straight line graining and finishing
- Deburring – rounding + stronger rounding in one operation
- Deburring – rounding – oxide layer removal
- Deburring – rounding – orbital finish
- Processing of punched parts or water jet-, laser- or plasma-cut sheet metal
- Deburring and rounding of 3D stamped parts
- Processing of small parts from 20 mm diameter
- Processing of foil-coated or galvanised sheet metal
- Processing of steel, stainless steel, aluminium…
Technical Data

Options
Rotating Cleaning Brush
Ideal for cleaning the conveyor belt from below on the outfeed side.
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
Quick-Fix tool connector for speedier changing of discs e.g. when alternating between steel and stainless steel.
Lighting
LED lights inside the machine.
Magnetic Track
Permanant magnetic track below the feed belt for holdin 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
When processing aluminium a lot of fine, light dust is created. Extraction hoods around the discs enhance the dust extraction process.
Floating head system
The unique LOEWER floating head system is designed for the abrasive belt unit and makes it possible to regulate the grinding pressure. It allows the entire unit to move out of the way if the grinding pressure gets too high. The system prevents the workpiece overheating and protects the expensive contact drum from damage.
Conveyor tables
When processing longer work pieces it is helpful to use conveyor tables. These are available in different lengths and widths. As an optional extra the feed speed can be linked up to the feed speed of the machine.
Vacuum
High-pressure vacuum fan with frequency converter and perforated conveyor belt / table for holding down the workpieces.
Automatic calibration
Motorised adjustment of the individual discs with automatic calibration after tool change or for wear compensation.
Units/´Tools
LOEWER K – Abrasive belt unit with contact drum
The abrasive belt unit with a contact drum can be used for graining a decorative straight-line finish or for deburring. Depending on the application at hand, the hardness and diameter of the contact drum can be selected accordingly. For example a harder drum is better for straigh-line finishing whereas a softer drum will work better for deburring.
- Decorative straight-line finish
Our abrasive belt units can be equipped with the unique LOEWER floating head system. This system allows the entire unit to move out of the way if the grinding pressure gets too high. It also prevents the workpiece overheating and protects the expensive contact drum from damage.
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 its location on the feed belt.
- 360° processing from all directions
- Even wear of all discs
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.
OrbitalDisc for creating a non-directional finish with the LOEWER Orbital device for which there is a patent pending.
Flexible SmartFlexDisc for edge rounding foil-coated, zinc-coated or deformed sheet metal parts.
OxideDisc for removing the oxide layer on side edges.
Endless abrasive belts and nylon abrasive belts in different grit sizes and grain types.
