Here at Astley-Diamond Tools we specialize in the manufacturing of electro - plated diamond tools, offering a high quality strip and replate service, using both diamond and CBN

Introduction:

Electroplated diamond tools, represent a product that is reliable, accurate, economical and efficient. We will provide you with high quality tools, that have a wide range of applications, for a wide range of materials.

Grit sizes and applications:

We carry a wide range of diamond, cubic boron nitride, (black and amber). Diamond is usually used for the working of, tungsten carbide, plastics, glass, glass fibre, ceramics, carbon, cermets and various other materials. Where as CBN is most commonly used on hard steels.

Wheels:

Diamond, CBN, and ABN wheels, have only a thin layer of very hard abrasive, highly concentrated over the grinding surface. Because of this high concentration of abrasive, plated wheels will cut very freely, are less likely to load than conventional wheels, and be produced to almost any profile.

Wheels cannot be trued on the spindle and therefore it must be mounted and clocked accurately before commencing grinding. Failure to do so will usually cause premature breakdown or serious damage to the wheel and could result in damage to your equipment and machinery. It is not possible to dress an electro plated wheel but, loaded wheels can be cleaned by scrubbing vigorously with detergent.

In general electro plated wheels are designed to operate in the speed range 4,500 - 6,000 s.f.p.m. although for small routers, internal grinders, cone points etc, the operating speed is usually lower, dependent upon the equipment available and the safety regulations governing these small mounted points.

Formed wheels:

When designing forms of this type, it should be remembered that sharp corners cannot be produced due to diamond build up, also the greatest stress is applied to sharp forms which causes greater wear. The actual size radius which can be produced, is shown in table 1, as is the diamond build up.
