The Dutch company Kinkelder has established a global reputation for its carbide-tipped circular-saw blades, high-speed-steel circular-saw blades and segmental circular-saw blades.
For producing and re-sharpening these, the company has more than 20 sharpening machines from Vollmer (
www.vollmer-group.com). Among the most recent acquisitions are the CHD, CHF and CM models.
Kinkelder managing director Erwin Hissink says: “We run our own research department and do everything possible to perfect our circular saws. We currently manufacture 100,000 saw blades a year, 90% of which are sold abroad.” The family-run company was founded in 1945 and now has over 350 employees working at 14 subsidiaries in eight countries.
The Vollmer CHD, CHF and CM machines allow carbide-tipped circular-saw blades to be sharpened with precision; they also allow saws to be finish-machined in a single process without the blades having to be clamped in more than one position.
Thanks to its eight CNC axes, the CHD sharpening machine can accommodate a variety of circular-saw blades and processes both the face and top of the teeth.
The CHF sharpening machine has seven CNC axes and measuring equipment for peripheral grinding on both sides of the blade. Kinkelder uses these machines round the clock, in combination with a handling system and appropriate loading carriage for automatic tipping.
