High speed resin-bonded grinding wheels for fettling
Phoenix Abrasive fettling wheels are available in sizes to suit all applications.
In simple terms, the grinding wheel consists of two main elements:
The abrasive grains which perform the actual metal removal which depending on the grinding application can be:
Aluminium Oxide – Because of its tough nature, this is recommended for use on metals having tensile strengths, such as onannealed malleable, hard bronze and steels.
White Aluminium Oxide – A refined form of the above that has a high degree of friability. It has exceptionally fast cutting properties.
Silicon Carbide – This abrasive is very brittle but it is also one of the hardest manufactured, thus being conductive to the efficient grinding of material of low tensile strength e.g. cast and chilled iron, aluminium, copper, brass, porcelain, etc.
Zirconium – This special abrasive, mixed with the other more conventional abrasives, possesses special characteristics which can be said to have revolutionised “fettling”. The percentage of Zirconium used to give the optimum results is dependant on individual users’ requirements and circumstances. Generally speaking, zirconium produces a faster cutting rate relative to grinding life, resulting in a major cost saving to the user.
Seeded Gel Abrasives – This latest grain technology whilst at a premium price delivers premium performance costs effectively.
The bond which holds the abrasive grains together.
After mixing, pressing, curing, over speed testing and stringent inspection control throughout each process, the finished product constitutes a compound of many thousands of cutting tools, bonded together to a selected strength and grain distribution, and with the added advantage of being self sharpening.
