Abstract
A cutter build and truing machine (22) comprising a mechanism (52, 54) to position cutting blades (98) by moving the blades in either direction in a mounting slot (96) of a cutter head (94). The machine further includes a torque spindle (62) and driver (66) to automatically tighten or loosen clamp bolts (102).
Claims20
A cutter build and truing machine comprising:
- a machine base;
- a cutter head spindle rotatable about a spindle axis B;
- a build carriage subsystem comprising a pair of blade positioning arms relatively movable toward and away from one another in a linear direction, said blade positioning arms being positionable for contacting a cutting blade at opposite lengthwise ends thereof, said blade positioning arms being further movable so as to position said cutting blade in a blade mounting slot of a cutter head releasably mountable on said cutter head spindle, said blade mounting slot extending in a lengthwise direction and said blade positioning arms being capable of moving said cutting blade in either direction along said lengthwise slot direction;
- and
- a driver tip in communication with a torque spindle, said driver tip being capable of engaging with and disengaging from a blade clamp bolt in said cutter head, said driver tip being operable to tighten said blade clamp bolt for securing a cutting blade in said blade mounting slot of said cutter head and also being capable of loosening said clamp bolt whereby said cutting blade is movable in said lengthwise direction of said blade mounting slot.

A method of building and truing a cutter, said method comprising:
- releasably mounting a cutter head on a rotatable cutter head spindle of a cutter build and truing machine, said cutter head having a plurality of cutting blade mounting slots located therein with each of said mounting slots extending linearly in a direction through said cutter head from a first side to a second side, each of said mounting slots having a clamping mechanism comprising a clamp bolt, said clamping mechanism being operable to clamp a cutting blade in said mounting slot and to release a cutting blade from a clamped condition in said mounting slot,
- providing a cutting blade in at least one of said cutting blade mounting slots, said cutting blade being in the form of a bar extending lengthwise between opposed ends,
- determining the position of said cutting blade in said at least one mounting slot,
- releasing said cutting blade from a clamped condition, said clamp bolt being retracted to effect said releasing by engaging said clamp bolt with a driver tip located on said cutter build and truing machine,
- contacting each end of said cutting blade with a respective positioning arm of said cutter build and truing machine,
- moving the positioning arms to effect movement of said cutting blade linearly in the direction of said blade mounting slot to locate said cutting blade in a desired position, the positioning arms being operable to move said cutting blade back and forth along said linear direction,
- securing said cutting blade in said desired position by clamping with said clamping mechanism, said clamp bolt being advanced to effect clamping by engaging said clamp bolt with said driver tip located on said cutter build and truing machine.
