SwingGrinder – 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.

  • 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

Model SwingGrinder M with under-table magnet

  • Under-table magnets for fixing ferritic workpieces with pneumatic lifting
  • The ideal solution for processing mild steel
  • Deslagging
  • Deburring
  • Edge rounding
  • Oxide layer removal

Vacuum Device
For holding down smaller and lighter workpieces. For most applications the vacuum device is often not required but it can be ordered at a later stage should it become necessary.

Quick-Fix Tool Connector
Quick-Fix tool connector for speedier changing of discs  e.g. when alternating between steel and stainless steel.

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

Pneumatic Weight compensation
Weight of the arm and grinding pressure pneumatically adjustable for more comfort.
