To enable tool manufacturers to grind PcBN cutting edges with high precision, Biberach-based sharpening specialist VOLLMER has retrofitted its VGrind 360S grinding machine.

Part of the VOLLMER Group, Loroch has supplied Cajhen with several grinding machines, which the tool manufacturer uses to produce and resharpen its circular saws.

To manufacture the countless product lines with thousands of new, re-sharpened and serviced tools being delivered each week, Systco has 11 Vollmer machines – three were delivered in 2022.

Microtools are drills and milling cutters with diameters below 0.5 millimetres. VOLLMER has succeeded in eroding such delicate PCD tools highly precisely and cost-efficiently with its VHybrid 260 grinding and erosion machine.

VOLLMER has designed its CS 860 and CSF 860 grinding machine duo specifically for grinding these carbide-tipped circular saws.

VOLLMER is inviting its customers and partners to the industry days event, which will take place from 18th to 20th April 2023 in Biberach.

The Ligna woodworking trade fair will open its doors in Hanover from 15 to 19 May 2023. Vollmer will be present at stand B58 in hall 27.

The sharpening specialist VOLLMER has boosted their VHybrid 260 grinding and erosion machine, and now achieves a surface quality of 0.05 μm/Ra (micrometre/average roughness value) when eroding PCD tools (polycrystalline diamond). The process innovation succeeded thanks to the optimisation of the Vpulse EDM Generator.

For this purpose, the components are guided along in a process water basin upstream of a patented ultrasonic sonotrode, whose generated vibrations cause the burrs to oscillate in an energy-efficient manner and break off with sharp edges in a process-safe manner. Since July 2022, the start-up ultraTEC has been a company of the international VOLLMER GROUP from Biberach an der Riß.

The new duo of VOLLMER grinding machines designed for machining carbide – tipped circular sawblades, is made up of the CS 860 and CSF 860.The sharpening specialists VOLLMER are presenting the machines, which stand out in particular thanks to uniform and intuitive operation, at the GrindingHub 2022 trade fair in Stuttgart.
