회사 소식 The importance of double bore bed for the production of long arm of large excavators

Due to the fact that excavator extension arms belong to large heavy industry products, large specialized equipment is required for efficient and high-quality processing and manufacturing, in order to maximize processing quality and manufacturing level, such as CNC plasma cutting machines, large groove milling machines, plate rolling machines, large welding displacement machines, large floor boring machines, large shot blasting machines (essential), etc

Why does the extended arm require a double headed boring machine?

Example

Assuming an extended arm has two ear plates on the left and right sides

If only processing from one side and boring the left side before processing the right side, it is more likely

to produce:

The left and right holes have different axes.

The dual head boring machine allows the boring heads on both sides to be machined according to the same reference, thereby ensuring the coaxial relationship of the holes on both sides.

This is very important for excavator extension arms.
