About THELEICO
THELEICO Schleiftechnik is an independent, self-financed family company from Meschede in the Sauerland, in existence since 1880. Since 1924 the company has produced vitrified-bonded abrasive tools, and since 1935 additionally resin-bonded grinding wheels, grinding points, and cutting-off and rough-grinding discs. The product range is complemented by superabrasives with CBN and diamond grain as well as dressing tools. Production takes place on 10,000 m² of production space with CNC-controlled systems and presses of up to 3,000 tonnes of press force; around 250,000 abrasive tools are produced annually. The delivery range includes diameters from 3 to 1,346 mm and weights from 0.001 to 300 kg. Customers include the automotive industry, transmission and engine manufacturing, the springs industry, rolling mills, rail construction, foundries, turbines and aerospace, the energy sector, machine and tool engineering, as well as the wood, glass and plastics industries. The products are delivered to 42 countries.

Abrasives and Bonding Systems
Sintered aluminum oxide
High-quality abrasive grain for vitrified and resin-bonded abrasive tools with high performance.
Regular aluminum oxide
Standard grain for conventional grinding applications in both bonding systems.
Fused aluminum oxide (white and red)
High-purity grain for increased demands on surface quality and precision.
Monocrystalline aluminum oxide
Grain quality for demanding grinding tasks with long tool life.
Zirconium aluminum oxide
Tough grain, mainly in resin-bonded rough-grinding and cutting-off tools.
Silicon carbide
Abrasive grain for hard and brittle materials.
CBN
Superabrasive for precision high-volume series processes and new materials.
Diamond
Superabrasive for maximum machining performance and lowest wear.
Vitrified bond
Fired at 1,000 to 1,400 °C; high grain retention forces, high temperature stability, unlimited shelf life.
Resin bond
Cured at up to 200 °C; high impact and break strength, suitable for wet and dry grinding.
Aluminum (backing)
Backing material for CBN and diamond abrasive tools.
Steel (backing)
Backing material for superabrasives in steel design.
