The process flow

 

Raw material inspection

The raw material comes in the form of wire. First visually check the quality of the material and the absence of any defects. Verify diameter and review raw material certificate.

Cold heading

A cold header cuts a specified length of wire into a cylindrical blank. Then, the two hemispherical head molds the blank into a roughly spherical shape. The forging process is carried out at room temperature and a small amount of excess material is used to ensure that the cavity is completely filled. Cold heading occurs at a very high rate, with cycle times averaging about one large ball per second. Smaller balls progress at a rate of two to four balls per second.

flashing

Excess material formed around the precision steel ball is removed during the flash process. Ball bearings are passed several times between two recessed cast-iron plates, removing a small amount of excess material as they roll.

Heat treatment

The parts are then heat-treated using quenching and tempering processes. A rotary furnace is used to ensure that all components are exposed to the same conditions. After initial heat treatment, the parts are immersed in the tank. This rapid cooling (oil quenching) produces martensite, a steel phase with high hardness and excellent wear resistance. Subsequent tempering operations further reduce the internal stress until the final specified hardness range of the bearing is reached.

grinding

Grinding is performed before and after heat treatment. Fine grinding (also known as hard grinding) brings the ball closer to its final requirements. The grade of precision metal ball is the standard to measure its overall accuracy; The smaller the number, the more accurate the ball. The spherical level includes diameter tolerance, roundness (sphericity), and surface roughness -- also known as surface finish. Precision ball manufacturing is a batch operation. The batch size is determined by the size of the machine used for grinding and grinding operations.

grinding

Grinding is similar to grinding, but the material removal rate is significantly reduced. Grinding is performed using two phenolic plates and a very fine grinding slurry, such as diamond dust. This final manufacturing process greatly improves the surface roughness. High precision or ultra precision ball grades require grinding.

Clean the

Cleaning operations then remove any processing fluids and residual abrasives from the manufacturing process. Customers who require more stringent cleaning requirements, such as those serving the microelectronics, medical, or food industries, can take advantage of Hartford Technologies' more sophisticated cleaning options.

Visually inspect the

After the primary manufacturing process, each batch of precision steel balls is subjected to multiple in-process quality control checks. Perform a visual inspection to check for defects such as rust or dirt.

Roller measurement

Roller measurement is a 100% sorting process that separates undersized and oversized precision steel balls. Check out our separate video on the roller measurement process.

The quality control

Each batch of precision balls is inspected to ensure grade requirements for diameter tolerance, roundness and surface roughness. During this process, other relevant characteristics, such as hardness and any visual requirements, are also evaluated.

packaging

At the end of the process, the precision balls are dried and packed in plastic bags. For easily oxidized materials, including vapor corrosion inhibitor paper. In some cases, a VCI bag is used. Precision balls can also be coated with dry contact oil. Finally, carton weights and labels are specified to meet strict customer requirements.

Packaging & Shipping

 

After Sales Service

 

We have a quality control room,And what we do here is we typically mainly look at size, crushing load specifications, surface clarity, hardness, and so forth to ensure that each individual ball coming off the line is up to standards.  Now, for some reason if you're not satisfied with anything we've given you, then  feel free to contact us and we will ensure your complete satisfaction in all the products from Foison.

Product Usage

So, where would you find our product? 

perhaps if you're opening a drawer at home, our balls will be found inside the slide rail in your drawer. So, we do furniture production, electrical appliances, kitchen appliances, medical equipment, scales and balances, automatic transmissions for cars, pretty much anything and anywhere that you would need a high-quality small ball, even ball bearings, you'd find us there.

Our main countries of export include South America, North America, Europe, Southeast  Asia, even Africa. So, if you have any inquiry or questions, feel free to email us or give us a call.

 We look forward to hearing from you.
