Innovative
deburring and
finishing machines

Loewer manufactures a complete
line of machines for 360° Deburring.

BeltMaster K4TD

Grinding, deburring and edge rounding machine in a working width of 1.350 mm or 1.500 mm

The BeltMaster K4TD is equipped wiith one abrasive belt unit followed by two oscillating disc units, each with two large rotating discs. The abrasive belt unit can be equipped with the unique LOEWER floating head system. The combination of abrasive belt unit and 4TD disc technology makes the BeltMaster K4TD the versatile solution for graining, deburring, edge rounding, oxide removal or orbital finishing.

MAIN FEATURES

• Abrasive belt unit for graining or deburring with infinitely variable abrasive belt speed
• Two disc units in the centre, two disc units on the outfeed side
• Oscillation stroke larger than width of feed belt
• Uniform, 360° edge rounding from all directions on inside and outside contours
• Uniform wear of disc tools, independent of the size of the work piece or its position on the feed belt
• Speedy change of tools when using different materials
• Great versatility due to large selection of disc tools for different applications

Swing Grinder – The Original

For quick manual deburring and edge rounding

Before LOEWER introduced the SwingGrinder in 2009 there were two main methods for deburring laser-cut or punched metal parts. Either this was done manually using power tools or expensive through-feed machines were used. The Original LoewerSwingGrinder bridges the gap between the two and offers the semi-automatic solution.

The grinding head consists of two rotating disc tools mounted to a swinging arm equipped with a weight compensation device. This grinding head is guided over the workpiece by hand and grinding pressure is applied manually from above. The inside and outside edges of the workpiece are processed efficiently from all angles and directions. The grinding head can be tilted 180° , thus allowing for speedy switching from a deburring disc to a rounding disc for example.

MAIN FEATURES

• Three to four times faster than manual deburring
• Easy-to-use with swinging arm and weight compensation
• High friction table cover, dust drawer and extraction outlet
• Rotatable head with deburring and edge rounding tools
• Numerous safety features including automatic motor shutdown when head is tilted and pneumatic brakes for swinging arm
• For laser-cut, plasma-cut and punched parts
• Processing of foil-covered or zinc-plated parts
• Processing of steel, stainless steel and aluminium
• Model “SwingGrinder M” with two pneumatically lifting magnets under the table mat for holding ferritic steel parts

DiscMaster 4TD

Efficient through-feed machine for laser job shops in working widths of 1.000mm, 1.500mm and 2.000mm

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.

MAIN FEATURES

• 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

TECHNICAL DATA

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