With Columbia TYROLIT raises the curtain on a new generation of race and bore wheels.

Columbia by TYROLIT closes the technological gap between conventional grinding wheels and superabrasives.
Superb performance raises and maximizes the machines potential. Proven application technology minimizes the risks of testing, furthermore our innovative tool concept, bond and grain material give you the edge over your competitors.

• High stock removal performance through artifical porosity and therefore improved cutting ability
• Extended wheel life because of ideal wear behaviour through highly concentrated sintered aluminium oxides in special CVOL bond
• Grinding time down by  up to -30%, increases the dressing interval by up to 10 times
• Perfect dimensional accuracy
• Good surface quality
• No sulphur contamination of the coolant - superior cutting performance is archieved without sulphur treatment
• Instant success with our winning combination of bond, grain and structure

APPLICATIONS:

• Bearing industry: internal rings (bore), external rings (race)
• Automotive industry: CV joints, bearing bushings, races (bearing seat)
• Gear industry: gear wheel bores
• Tool manufacturing industry: bores of various tools
• General machine construction: general internal cylindrical grinding in series production

GENERAL INFORMATION

In comparison with other grinding operations, internal cylindrical grinding wheels have to compensate for a number of process-related disadvantages:

As a result of the small diameter, there are fewer abrasive grains on the circumference. Each single grain is subjected to a significantly higher load.

Supply of coolant/lubricant is often not optimally possible for space reasons.

COLUMBIA wheels master such conditions with ease. Tyrolit’s specialist application engineers match COLUMBIA products to individual requirements and thus minimise the need for testing.

In addition to straight grinding wheels (with or without recess), Tyrolit also manufactures all types of edge profiles.
