The Danish tool manufacturer puts its trust on the sharpening specialist Vollmer and takes services to the next level. Danish tool manufacturer TN Værktøjsslibning, that means “tool grinding” in English, produces coated, solid carbide milling cutters and drill bits, which can be made to order or can be chosen from more than 50 standard models. It also offers resharpening services and advice. At the beginning of 2020, TN Slib decided to purchase the VGrind 340S tool-grinding machine, which Biberach-based sharpening specialists Vollmer had brought to market a year earlier. The VGrind 340S is a newer iteration of the time-tested yet highly innovative machine concept on which the VGrind series is based.
TN Værktøjsslibning (TN Slib) is one of Denmark’s leading tool manufacturers and is based in Bjæverskov, approximately 50 km south west of Copenhagen. TN Slib specialises in developing bespoke stepped milling and drilling tools in close collaboration with the customer. In order to increase the quality and precision of its cutting tools, the tool manufacturer invested in a Vollmer VGrind 340S grinding machine at the start of the year.
“We see great potential in our collaboration with Vollmer, both now and in the future,” says Torben Nielsen, founder, owner and CEO of TN Værktøjsslibning. “When we met at EMO 2019 in Hanover, we were very impressed by Vollmer. We particularly liked the friendly, in-depth exchange in which we discussed optimising the grinding machines for our specific requirements.”
Using the VGrind 340S grinding machine, TN Slib seeks to drive forward the development and production of small milling cutters and somewhat larger drill bits with diameters of between 0.3 and 8 mm. Delicate tools like these are facing increased demand in the manufacturing industry because of the ever tighter spaces encountered in mobile devices, medical equipment and automotive technology. Vollmer designed the VGrind 340S specially for machining small solid carbide cutting tools. With its two vertical spindles for different grinding wheel sets, the grinding machine allows for multi-level machining. This enables TN Slib to cut down on non-productive time and further improve tool quality. Five optimally configured CNC axes achieve interpolation with short travel distances for the linear and rotational axes, which in turn reduces the time required to machine workpieces and allows for incredibly tight tool tolerances.
“Medium-sized tool manufacturers like TN Værktøjsslibning are increasingly using machining tools that are tailored to their specific requirements,” says Jürgen Hauger, CEO of the Vollmer Group.
“The basic concept behind our VGrind product family enables us to configure sharpening machines on a modular basis and optionally adapt them to processes that are desirable for tool machining – especially for custom toolmaking.”
