Abstract
A saw blade (10) is moved stepwise for complementary finishing operations through a first station (20) and a second station (40) and is stopped whenever a tooth (12) has reached a desired position at the first station (20). Finishing of a second tooth at the second station (40) simultaneously with the finishing of the tooth at the first station is prepared in that the position of the second tooth is determined, which position depends on tooth pitch errors, and a finishing device (60) is moved into a corresponding position for work.
Claims10
A multistep finishing process carried out on saw blade teeth, wherein
- saw blade (10) is moved step by step through a first station (20) and a second station (40) for complementary finishing operations,
- the saw blade (10) motion is stopped whenever a tooth (12) has reached a desired position in the first station (20), that tooth (12) is finished during standstill of the saw blade (10) at the first station (20), and
- the same tooth (12) later on is finished also at the second station (40),
- characterized in that
- to begin with, a starting point (A) is set which will be located remote from a predetermined edge (14) of the tooth (12) which is stopped at the second station (40) whenever the saw blade (10) has come to a halt, no matter what the tooth pitch error is,
- prior to each finishing operation of a tooth (12) at the second station (40), a sensor (50) is moved in longitudinal direction of the saw blade (10), starting from the starting point (A), to a reference point (B) which depends on the position of the edge (14) of that tooth (12),
- a finishing device (60), in each instance, is moved from an inoperative position into an operative position by a distance (z) which depends on the path (x) of the sensor (50) from the starting point (A) to the reference point (B) to finish the tooth (12) which is located at the second station (40), and
- following each finishing operation, the sensor (50) is returned to the starting point (A) and the finishing device (60) to the inoperative position.
