Polishing-Calibrating LM 65

LM 65 – Calibrating Polishing Machine For Marble.

Machine suitable for calibrating and polishing semi-worked strips and/or sized pieces in marble or similar stones.

Machine base in electro welded steel plates with fully worked top covered and protected by stainless steel covering over which conveyor belt passes.

Up/down movement automatic as material passes thanks to the electronic programmer to set length of time and position.

The machines are built on the specific requests of customers matching any kind of polishing process or any kind of natural stone.

Description

  • The main structure covered in electro-welded steel sheets.
  • Conveyor belt seated on a level surface, covered in stainless steel.
  • The belt runs on two cylinders – one at the entrance to the stretch belt, one at the exit with an electronically controlled variable speed gear motor.
  • Operating heads centrally housed on strong, electro-welded beam.
  • Pneumatic vertical movement on chrome column.
  • Transverse spindle unit beam movement powered by an electronically controlled electric motor.
  • Beam at the front bearing diamond calibrating heads.
  • Abrasive/calibrating head up/down movement is pneumatic; working pressure of individual heads can be regulated and seen on pressure gauge; automatic gauging of material thanks to the electronic programmer for time/position.
  • Individual heads can be excluded.
  • Conveyor speed/spindle-holder beam on display in real-time; motor absorption.
  • Fault-detection.
  • Individual heads with raising device for abrasive wear irrespective of material thickness.
  • LX board, placed away from the main body of the machine, provides power, auxiliaries, accident protection, and PLC.
