For best results, vary the type of knurl
depending on the type of lidding and web width.
head is aligned with respect to bench of the machine, the axis of the knurl
head alignment points being perpendicular on the displacement direction X and parallel with the bench mirror.
Pre-forming dimensions are purposely made smaller than the required finished size to accommodate the outward displacement or material flow generated by the penetration of knurl
teeth into the part.
The final step was to knurl
the thumb spurs, but how?
That's because we can be working both ends of the part simultaneously; we can drill, form an OD, and knurl
an OD at the same time.
Design features include an integrated nylon (non-metallic) locking element to prevent loosening of mating threaded hardware; a broaching knurl
to create a firm, interference-type fit resistant to rotation; and a shoulder to act as a positive stop during the installation process.
Pressed into the hole in the, plastic capsule, the knurl
would upset the plastic sufficiently to ensure that the brass rods would stay put during ultrasonic welding.
The rugged aerospace grade aluminum construction with double O-ring water protection and 1" knurl
body delivers a 70 lumens beam.
A diamond-back knurl
allows more torque to be applied, and an integrated hexagonal section enables the use of a wrench or crow's foot for even more torque.
A flat punch and anvil are engaged to squeeze the fastener with sufficient force so that the tips of the projecting knurl
teeth are embedded and the inside shoulder of the knurl
contacts the board.
A serrated clinching ring, knurl
, ribs, or hex head prevents the fastener from rotating in the metal when tightening torque is applied to-mating hardware.
