1 Machine: 2 Processes on a 1m2 footprint.

Process 1: Sanding graining and polishing box section and flat strip up to 150mm wide

At the heart of the Duo machine is a 2m abrasive belt with a medium hard rubber contact wheel above a through feed conveyor.  Feed the box section along the powered feed belt to give a consistent controlled grain / satin finish, and with abrasive belts readily available from 36 grit to 2000 grit the finish options are endless.  The feed speed of the conveyor can be varied between 1 and 10m per minute giving the operator total control of the grinding and finishing process.

Options for the grinding process

1.  Integrated wet feed cooling and filtering

2.  2 speed or variable speed control

3. Air blowers (remove excess water from the finished grinding surface)


Process 2:  Centreless tube grinding and polishing (optional)

The centreless tube polisher is mounted on the side of the abrasive belt and by reversing the belt direction the Garboli DUO has the capability to grind and satin finish tubes from 10mm to 89mm in diameter.  

Options for the centreless process:

1.  Variable speed inverter

2. Small tube feed system

N.B.  It may be possible to add the centreless module as a separate purchase but if that is required then the wiring needs to be installed during original manufacture.
