Pferd Polinox PNG Type Grinding Wheel - Mounted

• POLINOX Wheel Aluminium Oxide - Surface Conditioning PNG
• Made of several strips of corrugated nonwoven material, wound around a common core.
• The wavy structure of the non-woven material permits seamless brush matting of surfaces.
• 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.  

Advantages

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

Application examples

• 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

• Roughening
• Deburring
• Surface work
• Cleaning
• Structuring (matt finishing, brush matting and satin finishing)
• Fine grinding in multiple steps

Drive types

• Flexible shaft drive
• Straight grinder

• POLINOX mounted and unmounted grinding wheels achieve their best performance at a recommended cutting speed of 10̐20 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
