Edging, grinding and polishing of strippers, doctor blades and cutting rules

Strippers, cutting rules and doctor blades are products whose strip edge characteristics represent a decisive quality feature

Steel strip grinding stations achieve micro grinding at the strip edge respecting precise height tolerances. The strips are chamfered on a strip edging line. Finally the strips are polished.

In addition to that grinding machines are employed for straight finish grinding or serrating of single workpieces such as perforating knives.

In the printing and paper industry mainly machines are employed as follows:

CNC grinding machine with three or four axes for the grinding of bevels on circular knives by using a cup wheel for high material removal; programmable angle adjustment for the following processing

CNC controlled peripheral grinding machine with additional vertical axis for scalloped grinding and staggered tooth grinding of knives with up to 600 mm grinding length

CNC controlled peripheral grinding machine with up to three axes for scalloped, serrated and fluted edge grinding of knives, mechanical knives, industrial blades and similar workpieces

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 knives with a diameter of 50–500 mm (1.97"–19.68") or 500–850 mm (19.68"–33.46")

The steel strip grinding machine is used for one-sided grinding of pencil sharpener blades, abrasor strips,  machine blades and similar workpieces.

The double-sided grinding station machines technical blades, doctor blades, surgical blades and similar workpieces on both sides.

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 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 is one of the biggest strip edging machines in the modular system of JULIUS. It achieves any contour required 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/Kompakt 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/Kompakt is designed for the machining of wide and thick strips when a lot of material has to be removed at each tool.

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.
