Three major advantages: Micron-precision:
1. Cycle time advantage: • Grinding roundness:
• Hard preturning enables 0.1 to 0.5 μm
minimal grinding allowances • Roughness Ra: 0.1 to 4 μm
• Grinding replaces finishing • Roughness Rz: 1 to 3 μm

Simply automatic – dressing, balancing and sparking
Dressing
Whether aluminum oxide or
CBN:
Highest quality by dressing
with single grain diamonds,
tiles, rondists or diamond
rings from the clamping
device.
A large variety of grinding
wheel contours can be
programmed with ease.
Periodically dressing your
grinding wheel keeps it
sharp and in shape.
Balancing and sparking
Electromechanical balancing
head and solid-borne sound
sensor or motor current
for controlling the grinding
process.
Automatic sparking and
balancing reduces your cycle
times and produces highest
surface qualities.
