The new duo of VOLLMER grinding machines designed for machining carbide-tipped circular saw blades, is made up of the CS 860 and CSF 860. The sharpening specialist VOLLMER is presenting the machines, which stand out in particular thanks to uniform and intuitive operation, at the GrindingHub 2022 trade fair in Stuttgart. Thanks to simple control and programing via the touchscreen or keyboard, users can learn how to use the machine in no time. Innovative measuring equipment, handling systems for unmanned machining, as well as the networked data exchange via a standard IoT Gateway, automate the production processes for carbide-tipped circular saw blades with various tooth geometries.
"Simplicity is the result of maturity." This quote from the German poet Friedrich Schiller touches the core of the new CS 860 and CSF 860 grinding machines from the German sharpening specialist VOLLMER. Thanks to sophisticated technologies, both machines are easy to operate and are highly automated in order to repair and sharpen carbide-tipped circular saw blades with diameters up to 860 millimeters (34 inches) in a single clamping operation.
Intuitive operation and fully automatic setup
While the CS 860 is suitable for grinding tooth faces and tooth tops on carbide-tipped saw teeth, the CSF 860 is designed for grinding of the tooth sides on circular saw blades. What both machines have in common is that users can control and program them intuitively via the touchscreen or keyboard thanks to the tried-and-tested VOLLMER operation. Since they have identical grinding wheel management, once the grinding wheels have been initially measured, they do not have to be measured again after they are changed. The machine automatically detects the newly inserted saw teeth and machines them to size in an oscillating manner. The feed pawl registers broken teeth in order to prevent the grinding wheels from breaking and also determines the tooth pitch. This means that it is not necessary to enter this manually and therefore prevents operator errors.
Automations for round-the-clock unmanned machining can be implemented using various VOLLMER handling systems from the ND series. Customers can combine up to three grinding machines with the ND robotic systems and depending on the equipment, they can be equipped with up to 650 circular saw blades. Using the standard IoT gateway (Internet of Things), the completely CNC-controlled CS 860 and CSF 860 exchange the recorded operating and machine data in order to determine the machine utilization in real-time, for example.
Carbide-tipped circular saws for cutting wood and metal
The duo of sharpening machines – CS and CSF 860 – are used in companies that require carbide-tipped circular saw blades for the cutting of wood, metal, or composite materials. Tool manufacturers can use the VOLLMER machines to automate the production of large volumes and sharpening services are able to flexibly machine circular saws from different manufacturers and types. Sawmills, contract sawmills, furniture manufacturers and producers of plate materials use the grinding machines to resharpen carbide-tipped circular saw blades in-house quickly and efficiently.
"In wood and metal processing, the carbide-tipped circular saw is indispensable as one of the main cutting tools; furthermore, thanks to their properties, they can often be resharpened multiple times," says Jürgen Hauger, CEO of the VOLLMER Group. "With our CS 860 and CSF 860, we are offering two grinding machines that are not only easy to use, but which can also be used by our customers to reduce the total costs for sawing performance and in addition, conserve resources."
Related Glossary Terms
- circular saw
circular saw
Cutoff machine utilizing a circular blade with serrated teeth. See saw, sawing machine.
- feed
feed
Rate of change of position of the tool as a whole, relative to the workpiece while cutting.
- grinding
grinding
Machining operation in which material is removed from the workpiece by a powered abrasive wheel, stone, belt, paste, sheet, compound, slurry, etc. Takes various forms: surface grinding (creates flat and/or squared surfaces); cylindrical grinding (for external cylindrical and tapered shapes, fillets, undercuts, etc.); centerless grinding; chamfering; thread and form grinding; tool and cutter grinding; offhand grinding; lapping and polishing (grinding with extremely fine grits to create ultrasmooth surfaces); honing; and disc grinding.
- grinding wheel
grinding wheel
Wheel formed from abrasive material mixed in a suitable matrix. Takes a variety of shapes but falls into two basic categories: one that cuts on its periphery, as in reciprocating grinding, and one that cuts on its side or face, as in tool and cutter grinding.
- pitch
pitch
1. On a saw blade, the number of teeth per inch. 2. In threading, the number of threads per inch.
- sawing
sawing
Machining operation in which a powered machine, usually equipped with a blade having milled or ground teeth, is used to part material (cutoff) or give it a new shape (contour bandsawing, band machining). Four basic types of sawing operations are: hacksawing (power or manual operation in which the blade moves back and forth through the work, cutting on one of the strokes); cold or circular sawing (a rotating, circular, toothed blade parts the material much as a workshop table saw or radial-arm saw cuts wood); bandsawing (a flexible, toothed blade rides on wheels under tension and is guided through the work); and abrasive sawing (abrasive points attached to a fiber or metal backing part stock, could be considered a grinding operation).
- sawing machine ( saw)
sawing machine ( saw)
Machine designed to use a serrated-tooth blade to cut metal or other material. Comes in a wide variety of styles but takes one of four basic forms: hacksaw (a simple, rugged machine that uses a reciprocating motion to part metal or other material); cold or circular saw (powers a circular blade that cuts structural materials); bandsaw (runs an endless band; the two basic types are cutoff and contour band machines, which cut intricate contours and shapes); and abrasive cutoff saw (similar in appearance to the cold saw, but uses an abrasive disc that rotates at high speeds rather than a blade with serrated teeth).
