Computer controlled multiple axis grinding machine for grinding saw blades

摘要

A saw grinding apparatus comprises a saw blade mount for mounting a saw blade thereto; a tool rack comprising multiple tool bays each for storing a grinding tool; and at least one computer numerically controlled (CNC) multiple axes grind wheel manipulator which uses each grinding tool to perform a saw grinding operation. The manipulator includes a spindle connectable to a grinding tool and is movable to a grinding position wherein a grinding operation can be performed on a saw blade mounted to the saw blade mount. The manipulator is also movable to a tool change position wherein the spindle can engage a grinding tool stored in a tool bay and can deposit a grinding tool in an empty tool bay.

1. A saw grinding apparatus comprising:
a saw blade mount for mounting a saw blade thereto; and at least one computer numerically controlled (CNC) multiple axes grinding tool manipulator having a spindle connectable to a grinding tool, the manipulator being movable along at least three linear axes and rotatable about at least two rotational axes to position the grinding tool in at least three tool grinding positions against a tooth of the saw blade, wherein the positions enables the grinding tool to perform grinding operations including a top grind, a face grind, and a side grind of the tooth when the saw blade is fixedly mounted to the saw blade mount; wherein the manipulator comprises at least three linear modules movable along the at least three linear axes respectively and a two axes rotary joint sub-assembly movably mounted to one of the linear modules.
