Balance is key for grinding machine supplier

A Schmitt Europe product story
Edited by the Engineeringtalk editorial team May 10, 2005

Accuracy, reliability and cost-effectiveness are the core attributes that originally led Centreless Tooling Group to select Schmitt as its preferred supplier of wheel balancers.

Accuracy, reliability and cost-effectiveness are the core attributes that originally led Centreless Tooling Group to select Schmitt as the preferred supplier of wheel balancers for its company's range of remanufactured grinding machines.

Today, ten years later, Schmitt's SBS automatic balancing systems are still at the heart of the relationship between the vibration control specialist and the Tamworth-based grinding machine supplier.

"Grinding is a precision process, and our machines have a hard earned reputation for top quality engineering and performance", says Richard Aukland, Group Sales Manager for Centreless Tooling.

"We recognise that an effective wheel balancing system enables our customers to achieve the maximum return on their investment - by extending wheel life, increasing productivity and providing substantial savings in machine downtime and maintenance".

"Like most people, when we saw the capabilities Schmitt's system in action for ourselves, we were impressed by its speed and accuracy".

"Over the years, the SBS equipment has also proved to be extremely rugged".

"It certainly matches the high standards of performance and reliability of our own machines, so we have no qualms about recommending its use with our grinders".

Centreless customers vary from small subcontractors to major multinationals.

So, to meet requirements across the widest range of applications, Centreless offers Schmitt's automatic balancer system in both contact and noncontact operational forms.

Using the principle of mass compensation to correct unbalance, each type features a balance head containing two movable eccentric weights, which are positioned accurately by high precision gear trains.

During the balance cycle, the grinding machine is run at normal operating speed.

Out of balance forces are detected by the system's vibration sensor and fed back to the controller, which automatically adjusts the position of the weights in order to minimise the input signal.

Typically achieving results of less than 0.02um (peak to peak) at speeds ranging from 300 to 10,000rev/min, Schmitt's SBS system is designed as an inexpensive, permanent attachment for grinding machines with wheels from 6 to 48in diameter.

"Not only does the system eliminate the need for time-consuming manual wheel balancing operations, but it also provides improved component finish and dimensional accuracy and a dramatic reduction in wheel dressing frequency", notes Aukland.

With around 30% of Centreless grinding machines destined for export customers, reliability and customer support are also important factors in the company's recommendation of Schmitt as its preferred balancing system supplier.

"Overall, Schmitt perfectly complements our own skills resources and products", says Aukland.

"We therefore look forward to extending our companies' close working relationship over the next ten years, and beyond".
