Metals and lightweight materials are essential in many industry sectors, such as the car manufacturing and aerospace industries. These materials, as well as highly abrasive laminates and other materials in the woodworking industry, can only be machined economically by particularly high-performance, high precision tools. The rotary tools used for this type of machining are manufactured from carbide or PCD blanks, or are equipped with PCD cutting edges. Vollmer offers sharpening machines that are controlled accordingly by CNC technology for both tool types.
The sharpening process plays a key role in the production of drills, milling cutters and chippers made of PCD or carbide. The sharpening process determines the tool's level of precision and service life, as well as being the definitive mark of quality. It also sets the highest standards for the tool grinding machines used for their manufacture or machining.
VOLLMER erosion and grinding machines meet these high quality standards.
Efficient, high-precision machining is the key to the manufacture of PCD rotary tools.
VOLLMER has a unique portfolio of intelligent, powerful high-tech CNC-controlled erosion machines specifically for machining complex rotary tools – both for production and service.

When brittle, hard metal materials coalesce with relatively soft metals, primarily from the iron family (iron, cobalt, nickel); a material is created that is characterized by a high level of hardness as well as viscosity, known as carbide.
Its huge resistance to wear and capacity to withstand even massive physical loads make it a much sought-after material in many sectors: Including mechanical engineering, the automotive, steel or food industry.
Machining processes such as rotating, milling, drilling, engraving, sharpening and grinding are almost inconceivable without carbide. It is also used in non-cutting forming or for protection against wear. In the field of tool manufacturing, the hard metal is mainly used for indexable inserts, as solid carbide rods or in the form of precision tools like drills and milling cutters.
BENEFITS OF CARBIDE GRINDING WITH VOLLMER
Tool grinding machine for the production of carbide drills and milling cutters with a diameter of up to 100 mm. The workpieces can be machined on two vertically configured grinding spindles. The optional tool automation for eight tools changes the grinding wheels on both grinding spindles in the shortest time possible.
Professional care and maintenance is the key to effective and productive use of your carbide or high-speed steel circular saw blades.
VOLLMER has a uniquely diverse portfolio of high-performance advanced grinding machines for sharpening, maintaining or brazing circular saws. For tool production, chipping saw mills or a sharpening service – VOLLMER has the right solution for your specific needs. And there's more to the blades than just grinding them; we also have impressive solutions for other important process steps for your circular saw.
BENEFITS OF VOLLMER SHARPENING MACHINES FOR CIRCULAR SAW BLADES
VOLLMER technologies, ranging from manual sharpening machines to handling systems for fully automated complete machining, ensure that circular saw blades are ground to your requirements. The variety of solutions matches the economic efficiency and quality of your machining process while guaranteeing maximum precision. The VOLLMER sharpening machines for circular saw blades considerably improve your production processes in circular saw machining. With VOLLMER technologies and services, you benefit form:
When it comes to grinding circular saws, a precisely ground tooth side contributes significantly to the surface quality and cutting quality. For sharpening, maintenance or annealing, VOLLMER has the ideal solution tailored to your needs in the treatment process.
SIDE GRINDING MACHINES FOR MAXIMUM PRECISION
In addition to best cutting results, VOLLMER machines offer you a multitude of advantages when machining the side angles of your circular saw blades:
Professional treatment and care of your circular saws is the key to efficiency and productivity. For tooth tops or faces of saw blades – we have the perfect solution for every task.
Grinding tooth faces and tops is essential for the productivity of a carbide saw blade. With intelligent machine concepts, maximum precision and convenient operation, VOLLMER offers you the ideal solution for excellent surface quality. The saw face grinding machines are characterized by their sturdy structure and a high level of robustness and durability.
THE MAIN ADVANTAGES AT A GLANCE
The accurate sharpening results achieved by VOLLMER machines when grinding tooth tops and tooth faces of circular saws is the result of a whole host of advantages:
Carbide-tipped band saw blades are finding more and more applications in the metal-cutting industry. They are mainly distinguished by their small dimensions in relation to the often oversized pieces that need to be cut down. The advantage of carbide-tipped bandsaw blades for cutting metal lies in the very narrow cutting channel and the small machining losses.
In carbide-tipped bandsaws, small carbide pieces are welded onto a special carrier material that is highly resistant to various forces and stresses, even at high cutting speeds. Through fine grinding, the teeth obtain their vertical geometries, which depends on the material to be cut. The effective use of bandsaws for cutting metal requires maximum precision in the tooth geometry. That's a fact – and we know it. That's why, at VOLLMER, we have tried-and-tested solutions that have been specially developed and constructed for these requirements: For grinding tooth tops, straight tooth faces and clearance surfaces on both sides.
And in the last 100 years, we have not just focused on machines, but also on the people who operate them. In order to make work as easy, safe and pleasant as possible, we abide by the VOLLMER operating concept: Intuitive and logical.
