Danish cutting-tool manufacturer, TN Værktøjsslibning (TN Slib), has invested in a Vollmer VGrind 340S tool-grinding machine.
“We see great potential in our collaboration with Vollmer, both now and in the future,” says Torben Nielsen, founder, owner and CEO of TN Slib. “When we met at EMO 2019, we particularly liked the friendly, in-depth exchange in which we discussed optimising the grinding machines for our specific requirements.”

TN Slib makes around three-quarters of its sales in the production of bespoke, solid-carbide tools. The company also offers standard tools for cutting metals such as steel, aluminium, cast iron or copper.

Using the VGrind 340S grinding machine, the company 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 in increasing demand from the manufacturing industry because of the ever-tighter spaces encountered in mobile devices, medical equipment and automotive technology.

Vollmer designed the VGrind 340S especially for machining small solid-carbide cutting tools. With its two vertical spindles for different grinding wheel sets, the VGrind 340S allows for multi-level machining. This capability 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 tight tool tolerances.

A key factor in TN Slib’s decision to purchase the VGrind 340S was that the machine has the versatility to produce both small and large batches. The NUMROTOplus software enables 3D simulation of production processes and makes it possible to carry out collision monitoring in advance.
