Pferd Polinox PNZ Type Grinding Wheel - Mounted

• POLINOX Wheel Aluminium Oxide - Surface Conditioning PNZ
• The non-woven abrasive flaps are arranged radially with abrasive cloth interlayers. This flap structure permits an improved stock removal and produces a coarser finish.
• Abrasives:
  A = Aluminium oxide
• POLINOX mounted and unmounted grinding wheels are made out of non-woven nylon in which abrasive grit is embedded. The flexible open-cell structure of the non-woven material makes the tools very elastic and ensures cool grinding.

• Cool grinding and low thermal load on the workpiece
•  No clogging of the tool

• Producing matt and satin finishes on metals
• Cleaning of oxidized non-ferrous metals
• Seamless brush finishing of stainless steel (INOX)
• Surface roughening of plastics in preparation for adhesive bonding
• Surface adaptation of weld seams

• POLINOX mounted and unmounted grinding wheels achieve their best performance at a recommended cutting speed of 1020 m/s. This provides an ideal compromise between stock removal, surface quality, thermal load on the workpiece and tool wear.
• Flexible shaft drives, electric and airpowered straight grinders can be used as tool drives.

Safety notes

• The maximum permitted peripheral speed is 32 m/s
•  For safety reasons, it is imperative to remain within the stated maximum permitted rotational speed at all times
