Abstract

736,075. Grinding turbine blades. JAMESON, J. L. Feb. 4, 1953 [Feb. 4, 1952 ; May 14, 1952], Nos. 2954/52 and 12257/52. Class 60. The surface of a turbine blade 2 is finished by registering it with a die 1, disposing between the die and blade an abrasive band 3 having a width which is a fraction only of the length of the blade surface, and moving the blade and the die on the one hand and the band on the other hand relatively to one another in a direction lengthwise of the band and in a direction lengthwise of the blade. The first of these relative movements is effected by driving the band 3 and the second by mounting the blade holder 4 and the die 1 on a support 5 which is moved continuously or intermittently on slide bars 6 by an hydraulic ram and cylinder controlled by valves operated in timed relationship with the feed movement of the blade towards the die. This feed movement and the raising and lowering of the blade holder 4 may be obtained as described in Specification 719,124. The angle of approach and leaving of the abrasive band 3 to and from the die 1 are adjusted to suit the angle of twist at the particular part of the blade being treated by a drag box 14 and a roller 15. The former is carried by a frame 20 mounted on pivoted links 21 and is raised and lowered as the support 5 is moved by a control track in the latter which engages a stylus on the box. To enable the band to run with sufficient slackness over the die, the box is fitted with rollers 16 ... 19 and an adjustable spring 26 which subjects the rollers 16, 18 to a frictional drag. The roller 15 is carried by a bracket 28 pivoted at one end about a vertical pivot so that it can be swung in step with the movement of the support 5. The band 3 is driven by being passed between a driven drum 8 and a belt 9 which passes over pulleys 10, 11, 12 of which one is driven. Alternatively, a reciprocating band may be used. Specification 591,890 also is referred to.
