4 Equipment and Materials
Using anti-fatigue testing machine to measure the shanks fatigue resistance. Work for multi-bit test machine, each of the work stations include a) ~ d) of
part.
a) lower grip pliers. fixed, hard steel flat and a height of 32mm ± 2mm, the width can be firmly clamped shank appropriate.
Jig b) on the clamp. can be adjusted, hard flat steel, the heart can tick embodiment 49N ± 2N force, this force is perpendicular to the lower clamp pliers flat
Surface, the rate of 4r/s. Force exerted by hook heart reciprocating motion, a back and forth motion to form a complete loop. up and down
Figure 1 a schematic view of the fixture clamp.
c) recording means counting the number of cycles when the specimen breaks.
d) controlling the clamp pliers [see a) and b)] which clamping force is 4900N · mm ± 50N · mm devices.
NOTE. You can use a torque wrench.
