FLANGE AND SPINDLE TYPE BALANCING HEADS
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.
These measuring heads are to be connected to P7 or P7WB electronic units.
FLANGE TYPE (FT) HEADS
Flange type (FT) balancing heads are simple to install on the grinding wheel, making them ideal for retrofitting. The extensive range of balancing capacities available (from 100 gcm to 7500 gcm) caters for the most diverse requirements.
Marposs FT balancing heads are available in two versions, either with retractable contacts or with contactless transmission and integrated acoustic sensor.
SPINDLE TYPE (ST) HEADS
Spindle type (ST) balancing heads were designed to be installed in the grinding machine spindle, making them ideal for new OEM applications.
The whole product range displays a high level of modularity which allows it to be used for the most diverse applications.
This modularity is given by the variability of the diameter (from 42 to 81 mm) and length (from 104 to 254 mm) which allow all of the necessary balancing capacities (from 400 to 13000 gcm).
Marposs ST balancing heads are available in two versions, either with retractable contacts or with contactless transmission and integrated acoustic sensor.
SPINDLE TYPE (ST) HEADS FOR HIGH SPEED APPLICATIONS
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.
CBN grinding wheels have very limited manufacturing imbalances, therefore, spindle type balancers have been sized with low capacity values (from 70 to 700 gcm). All of the versions are available either with a connector for separate contactless transmission (spindle with through-hole) or with an integrated transmission system (spindle without through-hole), both having an integrated acoustic sensor.
