Hollow grinding machine
HG/NT: Hollow grinding
CNC grinding machine with four axes for the double-sided hollow grinding of kitchen and steak knives, hunting and sports knives, pocket knives as well as hand tools like e.g. saw blades
- grinding with two cup wheels, each wheel at an angle of 45° to the blade
- thereby a consistent hollow bevel shape over the entire wheel life
- dimension of the grinding wheel depending on blank thickness, bevel width and thickness
- programming with contour caliper installed on the grinding machine
- grinding wheel outside diameters: 80 mm, 125 mm, 175 mm, 200 mm or 220 mm
- spindle motors completely closed and equipped with moisture protection
- two digital measurement controls integrated into the CNC control to supervise the wear of the grinding wheels
- integration of a CNC controlled scotch brite station in order to polish the piece in the same clamping
- wheel wear is automatically compensated after each grinding cycle with a digital measuring system
- automatic central grease lubrication system
- digital four-axle Windows controllers (X, Y, and the two spindle axes)
- grinding length up to 430 mm
- sensor programming, probing of contour shape and direct generating of necessary program data
- grinding wheels activated by special motors with precision mounted spindles
