Embodiment 1

[0023] A production process of small and micro precision bearing steel balls, comprising the following steps:

[0024] 1) Cold heading: Using a high-speed cold heading machine and a cold heading ball mold, the bearing steel wire is stamped into a cold heading blank ball, and the bearing steel wire satisfies the weight percentage of each component mentioned above.

[0025] 2) Light ball: Use the light ball machine and the light ball grinding fluid to grind the cold heading rough ball, firstly grind off the ring belt and two poles of the cold heading rough ball, and basically form a ball; then further grind to remove the surface oxide layer wear off. In this process, a semi-finished optical spherical blank is obtained.

[0026] 3) Heat treatment: After cleaning and drying the light ball blank, put it into a rotary furnace for heating and quenching with a controllable protective atmosphere. After quenching, it is tempered to obtain a semi-finished steel ball with a hardness valu...

Abstract

The invention discloses a production process of small and micro precision bearing steel balls. The main process includes: cold heading→light ball→heat treatment→hard grinding→cold pickling→strengthening→cleaning→primary grinding→precision grinding→finished product cleaning→photoelectric appearance inspection → Anti-rust packaging, etc.; the precision grinding process is concentrated in a closed space, and a special industrial vacuum cleaner is responsible for the sanitation in the closed space to ensure cleanliness; the temperature is controlled at 23±2°C by industrial air conditioning; when the air humidity is less than 60 %, the room air humidity is controlled at 60-65% by spraying clear water mist to the room. The invention ensures that the precision grinding process in the production process of the small and micro bearing steel balls is always carried out in an airtight, constant temperature, dust-free and moisture-retaining airtight space. The good processing environment ensures the quality of G10 and even G5 small and micro high-end bearing steel balls.

Description

technical field [0001] The invention relates to the field of bearing steel balls, in particular to a production process of small and micro precision bearing steel balls. Background technique [0002] Bearing steel balls are important basic components, especially small and micro precision bearing steel balls play a huge role in the development of the national economy. Under some special conditions, steel balls of special materials are often required to complete the functions required in different environments. In fact, some special material steel balls have been widely used in various fields of the national economy, including 9Cr18, 3Cr13 stainless steel, copper, aluminum, titanium alloy steel, agate, glass, ceramic balls, etc. Their popularization and application not only promote the development of the steel ball production industry, but also promote the technological development and scientific and technological progress of related industries. [0003] At present, in the p...
