Do you know the production process of bearing made in japan steel ball?

Today let's find out how the steel balls in the bearing made in japan are made:

Steel balls are indispensable for the bearing made in japan industry and crushing industry. Common steel balls include bearing made in japan steel balls, stainless steel balls, carbon steel balls, alloy balls, and so on. Although the steel ball is small, its load and life are very important in the world of transmission, and its production process directly affects product quality.

Let ’s take a look at the production process of advanced bearing made in japan steel balls:

01 Raw material
The materials of each specification and each furnace number are inspected. If it is a wire, it also needs to be drawn (drawn), and the wire is drawn with a wire drawing machine to the required wire diameter.

02 Cold heading
Under normal temperature conditions, the raw materials are plastically deformed to form a ball.

03 Flashing
The endless belt on the surface of the ball is removed, and the roughness of the surface of the bearing made in japan steel ball is improved, so that the ball is initially spherical.

04 Heat treatment
The ball is put into a heat treatment furnace, carburized, quenched and then tempered to make the ball have a certain carburized layer and hardness, toughness and crushing load. Some manufacturers use advanced mesh belt heat treatment lines to effectively control the process parameters of quenching and tempering time and temperature through various instruments to ensure the stability and controllability of product quality.

05 Peening
A processing method in which steel balls collide with each other through a strengthening machine, so that the surface of the bearing made in japan steel balls is plastically strengthened to increase the compressive stress and surface hardness of the steel ball surface.

06 Grinding
By fixing the iron plate and rotating the grinding wheel plate under a certain pressure, the surface quality and shape of the bearing made in japan steel ball are further improved.

07 Lapping 1
Using two cast iron preliminary research discs, and then adding abrasives, through a certain pressure and mechanical movement, to achieve the surface quality specified by the process.

08 Check
100% manual selection. In addition, flaw detectors: three methods of photoelectricity, eddy current, and vibration are used to select various types of defect balls, such as surface defects, shallow surface layer cracks, and internal material defects.

09 Laping 2

Using two cast iron lapping plates and adding abrasives, under the action of a little pressure and mechanical movement, some reserves are consumed to further improve the accuracy and surface quality of the steel balls.

10 Washing

The spiral cleaning machine and the lifting turnover box improve the cleaning quality and reduce the damage to the surface of the bearing made in japan steel ball, and continuously filter the cleaning liquid to ensure the cleanliness of the steel ball.

11 Final check
For each batch of bearing made in japan steel balls, final inspection is performed according to the requirements of the process, such as the roundness, hardness, metallography, and stress of the steel balls.

12 Oil, Pack
Use anti-rust oil, spray anti-rust and pack according to customer's packaging requirements.
