Circular knives for the food industry

The production of circular knives is a long lasting tradition in our company Herbertz. Since the year 1925 we are producing circular knives and round cutting knives "Made in Germany".

The manufacturing of circular knives must be adapted to the purpose of use. The selection of materials and the corresponding heat treatment are very important parameters. There fore one should adapt the cutting geometric to the desired cutting quality and to the intended use. The surface performance and the roughness depth should be adapted to the purpose of use of circular saws. We are in a position to manufacture the circular saw in a ground, brush polished or mirror polished execution. For some purposes of use coating of the circular saws proved one's worth. Further quality characteristics of circular saws are axial run-out, radial run-out and tolerances of the drilling. Our Know-How and our Circular knife grinding machinemanufacturing possibilities of circular saws reach tolerances, satisfying high ranking requirements.

Willingly we provide advice for the purpose of use of circular saws to optimise  the cutting performance and the endurance. We are manufacturing  circular saws for all kind of applications. Our circular saws are in use world wide. Our aim is to improve the endurance and the cutting quality. Our experience during decades supplying circular saws to different branches as  paper-,  wood-, steel-, plastic- , food- , elastomer and building industries is appreciated world wide.

Circular saws and round cutting saws are denominated depending their use as follows: Upper knife, lower knife, perforating circular knife,perforating spring circular knife,  circular spring knife, paper circular knife, crushing knife, hull circular knife, circular knife for  food industry,  circular knife, grooved knife, grooved lower knife, round cutting knife.
