Build the Replacement Around the Machine
Drawings, samples and machine information are used to prepare the replacement. Critical fit dimensions can be controlled to ±0.01 mm.
Brshear manufactures custom and replacement machine knives with direct support from engineering and production.
Our current focus is matched moving and fixed knives for plastic granulators and crushers, manufactured around the machine, processed plastic and working conditions.
Good steel provides the foundation. Reliable service life also depends on the right hardness, heat treatment, fit and finished cutting edge.
Drawings, samples and machine information are used to prepare the replacement. Critical fit dimensions can be controlled to ±0.01 mm.
D2, SKD11, DC53 and Cr12MoV are common options. Vacuum and cryogenic treatment help achieve stable blade performance.
The profile and cutting edge are finish ground, then agreed dimensions, hardness and appearance are checked before packing.
Drawing changes, material decisions and manufacturing questions stay with the team responsible for the order.
