Item Number: #
8" Dia Cap 10hp HP Supertec STC-1206 CENTERLESS GRINDER, 6" Wide Wheel
Maximum workpiece diameter
SUPERTEC MODEL STC-12 PRECISION CENTERLESS GRINDER
- Both grinding & regulating wheel spindles are made of
NI-CR-MO alloy steel, which is normalized and carbonized
hardened and ground for longer life and better accuracy.
- Hydrostatic Babbitt bearings type spindle with a 3-point
support design, surrounded by a high pressure oil film,
eliminates metal-to-metal contact to provide heavy duty
grinding capability as well as high vibration damping performance.
- A pressure switch interlock prevents spindle start-up
until oil pressure is established.
- This pressure switch interlock also stops the spindle if
oil pressure fails for longer spindle life.
- The regulating wheel travels on double V ways are hand-scraped
and Turcite coated for precise and smooth movement to ensure
high accuracy and longer way life.
- Both grinding & regulating wheels equip with hydraulic dressing
unit. Dressing speed is infinitely variable. Various profile
dressing can be achieved with optional template.
- Hydraulic dressing unit for the regulating wheel can be rapidly
and precisely swiveled up to ±3° for grinding taper in infeed
grinding and for providing better contact between workpiece
and grinding wheel to achieve better surface roughness, roundness,
- All gears in the gearbox are made of Chrome-Molybdenum alloy
steel (SNCM-21), are hardened and precision-ground for smooth
running and low noise.
- The hydraulic system is air cooled to maintain constant oil
temperature and separated from machine to eliminate vibration
and dissipate heat.
- The optional servo driven variable speed regulating wheel
helps to achieve optimal surface speed for a better cutting
capability and a superior surface finish.
- Optional automatic loading & unloading for infeed & thrufeed
can be custom-built to meet your requirements, allowing the machine
to be run unattended, at a high production rate, while maintaining a
