Development of new "UC51 Series" CVD coated grade for turning of cast iron

1.Technical features
• Higher wear and damage resistance than conventional cast iron turning grades. A toughened, high hardness carbide substrate and an additional highly wear resistant coating layer together with the development of ultra smooth coating technology for the top coating layer.

2.Novelty / Originality
• Use of a hybrid surface treatment technology, a combination of conventional smooth coating technology (mechanical treatment) and a chemical smoothing technology. Owing to the crystal control technology, a 50% finer crystal particle for the TiCN layer than previously available gave dramatically increased wear resistance.

3.Contribution / Benefits for the Association
• The achievement of long tool life for high-speed turning of cast iron and offering a tool that promises a great contribution towards reducing machining times.

Development of IMPACT MIRACLE end mills for machining hardened materials

1.Technical features
• The achievement of long tool life for machining pre-hardened mould materials.Enables efficient high-speed, stable machining and reliability for milling hardened mould materials over 60HRC.

2.Novelty / Originality
• The Single Phase Nano Crystal Technology increases the film hardness and oxidation temperatures of the (Al,Ti,Si)N to 3700HV and 1300°C, respectively. Additionally the friction coefficient at high temperatures is lowered. Special cemented carbide material and optimized cutting edge end and flute geometry increase wear and chipping resistance.

3.Contribution / Benefits for the Association
• Expanding of the work piece material range for machining pre-hardened mould materials in addition to extending tool life. Already supplying a great contribution to productivity increases and lead time reduction for highly accurate mould machining.
