This powerful heavy duty core sander is applicable mainly for calibrating core of plywood, multilayer board, blockboard, etc. This machine
has big motor power and big steel contact roller. It is very easy
to remove large volume of material to make the panel flat enough
but not smooth enough. So it is ONLY used for rough sanding with rough sandpaper. (40/60/80/120 grit sanding paper can be used in this sander.
- The main frame of the sanding machine is welded into integral-box
structure, which ensures high rigidity and operational stability.
This also guarantees the long service life of the core sander.
- The position of sanding roller is installed angularly, i.e., there
is a horizontal angle between the contact roller and the plywood
feeding direction. This special structure greatly improves the
evenness of the work piece. It is easy to solve the overlap problem
and the uneven problem of plywood. Besides, it can save about 20%
- The steel contact roller provides good thickness calibration
performance. And its large diameter allows the sand belt to be used
for longer time.
- The precise dynamic balance test of the contact roller, feeding
rollers, pinch rollers and tension roller makes the sanding result
- Our sanding machine adopts high-class brand frequency converter for
its feeding system, thus ensuring high efficiency and stability of
- Feeding system with feeding rollers and conveyor belt makes the
feeding more stable and the sanding result more precise.
- Strong and reliable sanding unit supplies you a stable sanding
- The feeding table can be adjusted up and down according to
different sanding requirement.
- Comprehensive control panel with advanced triggering computer
terminal and all-sided real-time data display makes the operation
easy and clear.
- Core sander with electronic pneumatic abrasive belt oscillation
system to control the abrasive belt move safely and stably around
the contact roller.
- Core sander with electronic pneumatic abrasive belt tension system
to make the belt work within a safe tension.
- Core sander with protection against the sanding belt running off.
- Core sander with automatic brake device on the sanding unit.
- Core sander with electronic pneumatic conveyer belt oscillation
system to make the belt work within a safe tension.
- Core sander with electronic pneumatic conveyer belt tension
- Core sander with full tools for adjustment and maintenance.
- The main motor is at one side of the heavy duty sander, which is
convenient for adjustment and maintenance.
- Test sanding belt provided for free.
- Core sanding machine equipped with a pressure gage that you can
control the abrasive belt tension by the digital display of this
