 Schmitt
Industries offers a product for every balancer need. We design, manufacture and
market a line of balancers that covers the diverse needs of the market—both
domestic and international. Our balancer line is made up of three principal types
of products:
Schmitt has introduced the SB 4500, a computer control system which intergrates
and standardizes the operation all of our balancers. This control has taken balancing
grinding machines to a new level of accuracy (.02 microns), speed (300 to 30,000
RPM) and convenience. With a electroluminescent display, the SB-4500 puts more
control and information at your fingertips. Quicker setups and dynamic graphic
displays keep you well informed.
Schmitt has become the leader in its industry by responding to market needs.
The company pre-engineers balancer applications, installs complete systems, offers
comprehensive customer service, and maintains ample inventory of all products.
In the U.S., external balancers are the optimum solution for most grinding
machines. Schmitt external balancers are easy to mount, highly reliable and require
little operator training, making them exceedingly popular. Internal balancers
are typically specified by European manufacturers of grinding machines, and hydrokompensers
fit unique applications when external and internal balancers are not appropriate.
Hydrokompensers are particularly suited for ultra-high speed functions--balancing
grinding wheels that rotate at more than 15,000 RPM.
Schmitt Balance Systems (SBS) offers a breadth of products that satisfies nearly
any manufacturing requirement. Schmitt also customizes balancers to fit applications.
As the needs of the machine-tool industry grow more sophisticated, Schmitt will
maintain its focus on the market, and continue to develop products that meet the
increasing process control requirements of our customers.
Dynamic
Balancing - is it necessary?
Vibrations on mechanical machines are unwanted phenomena which adversely affect
quality, productivity and reliability.
Vibrations on grinding machines are primarily caused by the unbalance in the
grinding wheel, thus producing relative motion between grinding wheel and workpiece
to be ground. Increased surface roughness and decreased control of part geometry
will result in the work. Frequent dressing of the wheel increases grinding times
and contributes considerably to early wear of the grinding wheels.
The centrifugal forces resulting from unbalance are squared at increasing grinding
speeds, thus limiting operational efficiency. The required smooth running machine
is obtained by elimination of dynamic forces, with grinding wheel unbalance being
corrected under operational conditions.
Grinding wheel unbalance varies during grinding and dressing processes. Absorption
of coolant and mass removal also produce vibrations which involve further dynamic
wear. Those effects are intensified as soon as the subcritical range of the grinding
machine is exceeded. In short, field balancing will result in higher precision,
efficiency and capacity.
