CNC grinding and balancing

It’s all about delicate balance

Computer Numerical Control revolutionised the ability of the cylindrical grinder, giving it precise directions on every dimension and measurement needed to produce the desired product. Combined with our large lifting capacity of 60 metric Tonnes, we can undertake all of your roll grinding requirements to the most demanding of variables using one of our two cylindrical roll grinders.

We can accommodate even the largest cylindrical rolls used within the paper and cable industries, giving a finish better than 1 micron up to 1.65metres in diameter up to 11 metres between centres.

A common engineering problem brought to us by customers here at Hotchkiss Engineers is excessive vibration in their rotating machinery – which can cause unacceptable levels of noise and, more importantly, substantially reduce the life of the shaft bearings. We can balance that machinery using our computerised dynamic balancing technology, which has the following specifications:

  • Up to 2.5m diameter x 11.5m length
  • Maximum component weight of 12 Tonnes
  • G1 – G6.3 specification up to 2500 M/Min
  • Print of certification of balance
  • Single and double plane balancer

Why choose Roll Grinding

Compared to ordinary cylindrical grinders, roll grinders are heavier, stronger and larger in size. They are more commonly used in the industrial fields processing materials such as paint, steel and rubber. Roll lengths can range from only a few centimetres up to several meters, with our machine capable or grinding up to 10 meters. Roll grinders provide a high finish for sheet metals and negate the need for polishing or further griding to get the desired finish. They also provide a convexity or convex surface to improve accuracy when in use.

The largest sizes with the smallest details

We can accommodate even the largest cylindrical rolls used within the paper and cable industries, giving a finish better than 1 micron up to 1.65metres in diameter up to 11 metres between centres.
