Abstract

The invention provides a machining technology of a ceramic spinning steel collar. The machining technology comprises a surface treatment process and a polishing process, wherein the surface treatmentprocess comprises the following steps that micro-arc oxidation surface treatment is conducted on a steel collar base body subjected to electrolytic polishing, MoS2 or PTFE particles are simultaneouslyadded into a micro-arc oxidation weak alkaline electrolyte, then an anionic surfactant is added, and stirring is conducted; and the polishing treatment process comprises the following steps that thesteel collar base body subjected to the micro-arc oxidation surface treatment is added into a polishing solution containing a grinding material and an auxiliary polishing grinding material for polishing treatment, and the polishing time is 2-4h. The service life of the ceramic spinning steel collar obtained by adopting the machining technology is prolonged, the labor and material consumption costcaused by replacing the steel collar is reduced, high-count, high-speed and high-density spinning requirements are met, the spinning speed is increased, the spinning quality is improved, and the product adaptability is improved.

Description

technical field [0001] The invention belongs to the technical field of processing spinning steel rings, and in particular relates to a processing technology of ceramic spinning steel rings. Background technique [0002] The steel ring is one of the important parts in the spinning process. It forms a pair of friction pairs with the traveler. It is in a fixed state on the spinning machine and cooperates with the spindle and the traveler to complete the spinning task. The spindle rotates in the center of the inner circle of the steel ring, and the yarn drives the traveler installed on the ring track to slide at a high speed at a speed of 30-40 m / s along the inner track of the steel ring, which generates a large centrifugal force and is in the In the dry friction state without lubrication, the instantaneous temperature of the contact surface is high, and the steel ring is easy to wear. [0003] The quality of the steel ring not only determines the performance of the traveler, b...
