Single-Flute Spiral Cutting Tools

February 12, 2012

LMT Onsrud LP, a leading manufacturer of solid carbide cutting tools, introduces balanced single flute spiral cutting tools to run at RPMs as high as 60,000. Manufacturers that specialize in marketing CNC routers for the sign industry have incorporated high speed spindles into their design. Most of these spindles turn up to 60,000 RPM compared to standard router spindle speeds of 24,000 RPM.

The advantages of high spindle speeds is an increase in feed rates in plastic, aluminum and wood sheet material, which are commonly utilized in the sign industry. Multiple flute tools are naturally balanced by design, but in some cases, single flute spiral tools are not. Single flute spiral tools are naturally unbalanced due to the location and amount of the carbide that is removed during the grinding process. LMT Onsrud has developed a method to balance single flute spiral tools by engineering design and a specialized manufacturing process.

"The market is demanding a balanced single flute spiral cutting tool. We listened to the customer and now are offering balanced tools up to 60,000 RPM," explains Jennifer Neubauer, Marketing Manager, LMT Onsrud LP.

The offering is part of LMT Onsrud's standard product line of upcut and downcut spiral "O" flutes for soft plastics, hard plastics and acrylics.

  • 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.
