/// THE MACHINE CONCEPT The CHF series is ideally equipped for sharpening carbidetipped circular saw blades, offering versatility which leaves nothing to be desired. /// Optimal movement coordination for short grinding times and reduced non-productive times, adjustable feed cam for the ideal tooth positioning /// 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 /// Proven VOLLMER drive technology for dynamic and reliable machining /// Five-axis kinematics for maximum flexibility...

/// THE APPLICATION Side grinding of saws for the saw mill industry, woodworking, plastics processing, aluminium 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 /// Machining of convex tooth flanks 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...

/// THE OPERATING CONCEPT The new multifunction handwheel makes work significantly easier and faster. The axes are selected and controlled 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: Optimised 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...
