The invention discloses a
machining process of a TP (topaz) bead ring for
spinning. The
machining process is characterized by comprising the steps of: 1, selecting materials: selecting an excellent-quality
alloy steel wire containing elements of W, V, Ni and Co as a
raw material; 2, flaking; 3, annealing; 4, forming; 5,
quenching-
tempering; 6,
polishing; and 7, carrying out surface treatment: nickelling the surface of a bead ring matrix by adopting a
chemical plating method, and adding a nano
powder body in a plating solution to ensure that the nano
powder body is co-deposited on the bead ring matrix; and 8, carrying out surface curing treatment: removing the stress and enhancing the
hardness to ensure the surface of the bead ring is golden yellow. The TP bead ring machined by adopting the
machining process has relatively good abrasion resistance,
friction reduction and
corrosion prevention properties, is capable of well meeting the requirement on the existing high-count, high-speed and high-efficiency
spinning, is particularly suitable for compact
spinning and common high-speed ring spinning, and has a good development prospect and a wide market popularization space.
