    Our company import the bronze gleitlager from viiplus china,viiplus professional team makes sure customs clearance is always smooth. They provide an accurate bronze bushing classification, handle all the paperwork,We have received the self-lubricating bronze bushings. They look well done and the high quality.
    Valerie from California
    We import the bronze gleitlager from China to under the incoterm FOB shanghai, sometimes by Air. viiplus is a very good bronze gleitlager supplier, they are very professional and patient, after we inform the new order, they will manufacturer bronze gleitlager in time and give us the schedule , and then we just need to receive the bronze parts

CNC alloy bushings are manufactured using an upgraded alloy when compared to OEM alloy bushings. The high nickel content of CNC alloy bushings increases wear properties while maintaining excellent metal lubricity. CNC bushings are specifically designed to prevent galling and decrease wear.
OEM CNC High Precisionpins you can expect value with higher performance.

What is four-axis CNC machining.

CNC is the abbreviation of numerical control, also known as computer gong, is a program controlled automatic machine tool.The control system can logically process the program with control code or other symbolic instructions, and then decode it through the computer, so that the machine tool can perform the specified action, and the blank material can be processed into semi-finished parts through the cutting tool.CNC machining is a new processing technology, the main work is the preparation of processing procedures, will be the original manual work into computer programming.

Composition of CNC system:

The CNC system consists of "CNC device", "servo system" and system program.
Numerical control device (special computer): hardware and software components.
Servo system: detection device, drive device and servo motor composition.
Four axis CNC processing plant share the following advantages of CNC processing:
(1) a large number of reduce the number of tooling, machining complex shape parts do not need complex tooling.If you want to change the shape and size of the parts, only need to modify the parts processing procedures, suitable for new product development and modification.
(2) the processing quality is stable, the processing accuracy is high, the repetition accuracy is high, adapt to the aircraft processing requirements.
(3) a variety of small batch production, production efficiency is higher, can reduce the production preparation, machine adjustment and process inspection time, and because of the use of cutting time and reduce the cutting time.
(4) can be processed conventional methods difficult to process complex surface, even can process some of the processing parts that cannot be observed.
Although it has been claimed that centrifugally cast bushings outlast Forging Turning bushings, many users who have tried these bushings have found that no other combination will outlast ours. Our original forged steel bushings have already proven to outlast any cast, centrifugally cast, or combination of either.
In addition to our CNC PINS AND BUSHING, VIIPLUS created a new line of Forged Steel Bushings for CNC industry.


CNC BUSHINGS:Standard Yield Strength


Material :


SAE4140 has high strength, high hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperatures. Forgings requiring higher strength and larger quenching section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, extremely loaded connecting rods and spring clips, can also be used Oil deep well drill pipe joints and fishing tools below 2000m.

Executive Standard: ASTM A29/A29M-04




SAE4140 steel, this steel has good processability, small processing deformation, and good fatigue resistance. It is a medium-hardened steel. After 4140 heat treatment, it has good strength and good comprehensive mechanical properties, good manufacturability and finished product rate. high. The maximum operating temperature is 427 degrees Celsius. 4140 high strength, high hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperatures. Forgings requiring higher strength and larger quenching section than 35CrMo steel, such as large gears for locomotive traction, supercharger transmission gears, rear axles, extremely loaded connecting rods and spring clips, can also be used Oil deep well drill pipe joints and fishing tools below 2000m, and can be used for molds of bending machines, etc.
