Method and apparatus for making helical flutes

1404491 Grinding helical flutes K P STANABACK 21 July 1972 34304/72 Heading B3D A method of machining helical flutes in a conical workpiece, such as a tapered end mill W, comprises orienting the workpiece with its axis generally tangential to the periphery of a rotary tool 44, such as a grinding wheel, advancing the workpiece along its axis relative to the tool with the smaller end leading while rotating the workpiece about its axis to form a helical flute, withdrawing the workpiece from the tool, rotating the workpiece through a predetermined angle before advancing the workpiece for a second time, repeating the latter three steps a number of times, periodically dressing the tool thereby decreasing its diameter, and after each dressing operation modifying the positional relationship of the tool and workpiece by an amount to accommodate for the smaller diameter of the tool. In apparatus for carrying out the method, the grinding wheel 44 is mounted on a spindle 42 driven by a motor in a housing 40 on a mount 46 vertically adjustable relative to a base 50 by a handwheel 56 or pawl-and-ratchet mechanism 58, 60 driven by a fluid cylinder 62. The grinding wheel is arranged so that its axis is at an angle to the direction of movement of a bed 14 on a base 12. A bar 70 extends from a platen 48 of the mount 46 and is secured to a reference bar 72 from which depends a vertical tapered stop 74. The stop is vertically adjustable with the grinding wheel and co-operates with an adjustable stop 76 on the bed 14. A carriage 24 has a main platform 21 which is generally L-shaped and slidable on guide rods 17, 19 mounted in blocks 13, 15 on the bed 14.

Sharpening system for ice skate runners

A skate sharpening system comprises an adjustor assembly and a skate holder assembly. A runner is releasably coupled to a template runner, and then clamped into the skate holder assembly. The template runner defines a pre-defined profile for the blank runner. An operator moves the skate holder assembly such that the template runner moves along a guide bearing of the adjustor assembly. The guide bearing is disposed proximate a grinding wheel. While the template runner remains in contact with the adjustable guide bearing, the runner remains in contact with, and moves along, the grinding wheel such that the grinding wheel simultaneously sharpens and contours the runner.
