Machine knife industry
Grinding | serrating | sharpening
The product range of the Berger Gruppe comprises several series of machines for grinding, serrating and sharpening mechanical knives. In cooperation with the German association of tool industry (FWI), the Berger Gruppe organizes special conferences all about mechanical knife production (read more).
We will exhibit at GrindTec from 10th to 13th of November 2020 in Augsburg (Germany).

CNC peripheral grinding machine with up to three axes for plunge grinding of serrated edges on knife blades (e.g. bread or steak knives), scissors and similar workpieces
The grinding station of the series WSL-CNC can be integrated into different machines to produce
scalloped or pointed serrated grinding.
CNC controlled serrated grinding machine for the machining of circular or cutter knives and for grinding insert seats of bodies of circular knives
Sharpening machine for sharpening knife blades and mounted knives
The double-sided grinding station machines technical blades, doctor blades, surgical blades and similar workpieces on both sides.
The steel strip grinding machine of the series BSM1500/TT-CNC is designed to deburr finish ground blades.
The grinding stations of the series BWSL1000/E-CNC achieve a one-sided straight finish grinding, a scalloped and a serrated edge grinding at strip material.
The grinding machines of the series BGM1500-CNC are designed for one- or double-sided grinding of doctor blades, knives for the food industry and similar workpieces.
The brushing and deburring station BSM3000/SP-CNC machines hair clipper blades, doctor blades, serrated machine cutting tools for food industry and similar workpieces.
The polishing station BSM3000/P-CNC is designed for polishing and deburring of microground blades such as doctor blades, scalpels, technical blades, pencil sharpener blades and similar workpieces
The breakers can be integrated into steel strip grinding and polishing lines or be mounted as a separate breaking unit with decoiler.
Polishing machine designed for sharpening and polishing of the cutting edges of circular knives
Robotic cell designed for machining circular knives with a diameter of 70 to 200 mm
The strip edge trimming machine of the series DUO works with 6 tools. Often the DUO is integrated into tube production lines to optimize the weld seam.
The TRIO strip edge trimming machine works with up to 9 tools achieving even complex contours at the strip edge.
The QUATTRO strip edge trimming machine achieves complex contours on the strip edge with 12 tools.
The QUINTO strip edge trimming machine is one of the biggest strip edging machines of the modular series working with 15 tools.
The BKB/S is designed for maximum material removal at each tool, which ensures that even complex contours with wide bevels can be machined on strip with heavy cross sections or hard material.
The strip edge trimming line of the series BHR/DUO is equipped with a DUO strip edge trimming machine, de- and a re-coiler. It is the basic line of the modular series.
Strip edge trimming line with a TRIO strip edging machine, a de- and a re-coiler and a strip width measuring system. The line machines strip edges with up to nine tools.
Strip edge trimming line with a strip edging machine of the serie QUATTRO, levelling, measuring and strip tension systems. The line is designed for the machining of complex contours an strip edges.
Strip edge trimming line with strip edging machine of the series QUINTO, levelling, brushing and calibrating machines as well as measuring and strip tension technique. The line is designed for machining complex contours also on thick and/or smooth strips.
The strip edge trimming line of the series BHR/BKB/S is designed for processing under high loads with high material removal.
Julius offers traverse winding systems at the recoiler and the decoiler side. It is possible to run in three ways – either from coil to spool, or from multicoil to spool or from spool to spool.
Decoilers and recoilers can be equipped with a strip tension system, a multicoil system and a traverse winding system. The coilers are integrated into strip processing lines.
The brushing machines of the series BS remove the dirt particles from the strip surface. They are designed to be integrated into strip edge trimming lines.
