Spindle Type ST Heads for High Speed Applications

marposs — Sat, 12 Sep 2009 16:48:50 +0000

The technology used on grinding machines, in particular with the use of CBN grinding wheels and electro-spindles, has allowed the circumferential speed to be increased up to 200-230 m/s.

Considering these requirements, Marposs has developed a spindle type (ST) balancer with coplanar weights suitable for high speed operation.

It is essential to control the vibrations induced in the machine as an effect of the imbalance of mechanical parts and the rotating grinding wheel.

Do you have machine instability with high vibrations ?
Do you have part quality issues?
Do you need to increase wheel cutting speed?
Does your wheel last not long enough?
Does your spindle need frequent repair?
Do you need to reduce maintenance cost?

Flange and Spindle Type Balancing Heads – Grinding Line

The Marposs balancer is an electromechanical grinding wheel balancing system for grinding machines which gives significantly improved part surface quality and increased machine life and productivity.

By measuring the vibrations caused by an unbalanced grinding wheel and suitably moving weights flanged to the outside of the grinding wheel (FT balancers) or inserted in the spindle (ST balancers), the system definitively eliminates the need to manually pre-balance new grinding wheels, whether made of conventional agglomerate, CBN or diamond, restoring optimum dynamic conditions for the entire life of the grinding wheel.

The wide range of balancing systems can be applied to most grinding machines for exteriors, grinding without centres, grinding for tables, flexible and special grinding, solving the most diverse application problems.
