The automotive industry is facing enormous challenges. Environmental issues and rising oil prices are driving people to pursue smaller, lighter, greener and more economical cars. The shortened life cycle of the vehicle and the transmission components has forced the factory to speed up production and reduce production costs.
Transmission parts are bulk products, so reducing the cost per piece of production is a top priority, but other requirements are also important, such as high process safety, reduced cycle times, and consistent, for critical lead times and lower production costs. Quality and so on.
Surface hardened alloy steel is the traditional raw material for transmission parts. Steel is generally heat treated to form a hard surface on the tough core surface. Other emerging methods include powder metallurgy and induction hardened mild steel grades.
Sandvik Coromant will do its utmost to help automakers produce high quality parts while reducing their total production costs and shortening production cycles.
CoroTurn TR
The precise and safe iLock T-locking track on the CoroTurn TR holder provides the highest accuracy and repeatability of the positive rake insert and prevents the insert from shifting, ensuring very small machining errors. Carbide and CBN (Cubic Boron Nitride) grades can be profiled in the soft and hard cars of the material.
Coromant Capto and RC
Good stability is the basis of any turning operation, especially for transmission system components that are structurally slender, vibration sensitive, and complex in shape. The CoromantCapto modular toolholder system and the CoroTurn RC blade clamping system provide excellent rigidity, repeatability and vibration protection for the negative rake inserts to best guarantee part quality.
CoroDrill 460
This universal carbide drill and custom options provide high productivity, stable tool life and outstanding production economy for machining lubricant holes.
CoroCut
The CoroCut1-2 tool's precision rail-type toolholders provide a highly efficient and safe solution for machining seals and locking ring grooves with a patented elastomeric clamping system and a GE-grooved CBN insert tip. Intermittent cutting of the shaft end of the quenching spark bond.
Hardened turning
Hardened turning (HPT) is a simpler process, lower cost, shorter production cycle, and avoids the environmental cost of coolant and grinding waste, making it a hardened part grinding process. Alternative method. Sandvik Coromant's powerful HPT solutions include CBN grades CB7015 and CB7025 optimized for cutting edge.
Soft car stage
Sandvik Coromant's new GC4315 and GC4325 carbide materials (using Inveio coating technology) enable higher cutting parameters while maintaining workpiece quality. If the excellent red hardness of the spindle cannot be fully utilized due to the speed limitation of the spindle, the feed rate can be increased to maximize production efficiency, and the blade with the wiper still provides the required surface roughness. If higher cutting parameters are not needed or can be used, tool life is expected to increase significantly.
to sum up
While the processing of automotive driveline components typically seeks to reduce the cost per piece, safe processes, surface integrity and efficient chip control are also key requirements. Sandvik Coromant is committed to providing superior technical service and process support to automotive component manufacturers and providing more efficient and cost-effective solutions for the entire process, from soft to hard, and grooving.
