hot sale bucket bushing sizes for excavator

A.Flange: good anti-corrosion effect

B.Electrophoresis: brighter black

C.Phosphating: similar to the flange, but the material is better than the flange, can be made black, gray

D.Chrome plating: the surface increases hardness, wear resistance is good, silver bright color looks good

The raw materials

We strictly control the procurement of raw materials, procurement of genuine steel mill steel production. Strict requirement for required steel, must meet all property standards of 45# and 40Cr steel. Ensure quality at the source of production.

Blanking

understage material equipment, adopt double blanking of lathe, manual marking of production, multiple precision, running the material, ensure the follow-up production of material preparation on the premise of precision.

Lathe

The advanced digitized lathe, with the mode of less deweighting and more turning, carries on the rough shape of the outer circle, and manually detects 100% of the product to ensure the standard of scientific data of subsequent processing.

Drilling

To realize the normalization, standardization and conformity of drilling program data. Under the premise of compliance with normal standards, the direct use of customers is more practical, more humanized and the actual operation of the understanding of this procedure. More convenient for customers, more appropriate use.

Quenching

The product is quenched by super audio quenching method to ensure that the product is heated at one time. In terms of product hardness, in order to guarantee product quality, there is no quality product with blasting lines or hidden cracks inside or outside. The hardness depth reaches 1.5-2.5mm, which makes it stronger and more durable.

Fine grinding

Intelligent precision grinding process is refined. Advanced precision grinding equipment is adopted. Under the principle of more turns and less quantity, manual supervision, measurement and adjustment are made for many times, so that the finished product can have a more refined appearance and the size can be reduced to the pursuit of "0" error.
