SERVICES:industrial blade manufacturing
With our high-tech CNC, NC and automatic grinding machinery, Renlaw offers a superior manufacturing and resharpening service. Super-abrasive grinding, using CBN or diamond wheels, provides tooling with a much higher cutting performance compared to standard processes due to excellent surface finishes, precise geometries and reduced thermal shock (using high-pressure coolant).
Our manufacturing process starts with the selection of the correct steel from our large store of imported German tool-steels and stainless knife-steels. Steels are pre-machined and then vacuum-hardened, and where necessary are cryogenically heat-treated to stabilize the metallurgical structure.
The hardened blanks are then tested in our laboratory before undergoing a series of grinding and finishing processes which bring them to their final geometries.
All blades are then inspected by our quality-control department to ensure that they conform to job-card instructions and technical drawings.
