Description: |
| Peck & Rector - patent attorneys
My invention relates to a universal cutter and reamer grinder for grinding milling cutters and reamers of all shapes, such as face mills, angular cutters, end mills, spiral mills, slitting-saws, and taper and straight reamers. It has for its object the improved construction and mode of operation of such grinders, whereby they are rendered universal, simple in construction and operation, and by which I am enabled to grind a straight-line clearance with smaller grinders than usual for this work, and in such a manner as to not heat the cutters to an injurious extent.
