CHF 1300 CNC-controlled machine for sharpening tooth sides on carbide-tipped circular saw blades up to 1300 mm in diameter

THE MACHINE CONCEPT

The CHF series is ideally equipped for sharpening carbide-tipped circular saw blades, offering versatility which leaves nothing to be desired.

  • Five CNC-controlled axes for beginning-to-end hydraulics-free complete machining of all commonly used angles in just one cycle – even for saws with group toothing
  • Oscillation grinding as standard – for high material removal rates in just one cycle, in line with the requirements for production and when replacing teeth during servicing
  • Optimal movement coordination for short grinding times and reduced non-productive times, adjustable feed cam for ideal tooth positioning
  • Proven VOLLMER drive technology for dynamic and reliable machining
  • Five-axis kinematics for maximum flexibility
  • Automatic central lubrication included in the basic equipment for reduced maintenance costs

THE APPLICATION

Side machining of saws for the saw mill industry, woodworking, plastics processing, aluminum processing and metalworking. Its high level of flexibility and superior grinding efficiency make the CHF series the first choice for many applications.

  • Automatic setting of all commonly used angles – including the hook angle – and automatic detection of the tooth pitch
  • Optional: Tooth pitch up to 180 mm thanks to a second feed pawl for greater flexibility, especially in a saw mill
  • Machining of convex tooth sides is also possible
  • Saw change possible without adjusting the mounting carriage – no need to set it up again
  • Optionally available with an even more powerful grinding motor and variable cutting speed for maximum grinding efficiency and optimized machining parameters for the process

THE OPERATING CONCEPT

The new multifunction handwheel makes work significantly easier and faster. The axes are selected and moved by only one module to avoid the possibility of incorrect operation. The handwheel is also used as a potentiometer in order to carry out speed adjustments in automatic mode.

  • Different grinding speeds can be entered depending on requirements: Optimized machining time or maximum surface quality
  • No need for manual adjustment of radial and tangential clearance angles, which means that operating errors are avoided. Values can be entered as angles or absolute values
  • Fully automated single-sided machining also possible (e.g. for conical prescoring saws)
  • No tooth pitch input required thanks to the feed pawl sensor system
  • Programming of special geometries as standard with a flank offset in the multi-surface program

Sharpening saw blades at the Yellow Sea

Hwaseong lies on the coast of the Yellow Sea in South Korea – around 50 kilometres from Seoul. The region is a popular sun holiday destination and has also made a name for itself in the sporting world. The footballer Bum-kun Cha was born here in 1953 – Asia's footballer of the 20th century. In the 1980s he played over 300 times in the German Bundesliga and scored just under 100 goals for the clubs Eintracht Frankfurt and Bayer Leverkusen.

Dutch company sharpens circular saws with Swabian technology

Dutch company Kinkelder has made a name for itself on the global arena with its carbide-tipped circular saw blades, high-speed steel circular saw blades and segmental circular saw blades. For producing and resharpening saw blades, Kinkelder has a fleet of more than 20 sharpening machines manufactured by Swabian grinding and erosion machine specialists VOLLMER. The VOLLMER CHD, CHF and CM sharpening machines are among their most recent acquisitions.
