Machine body

Column with cross slide structure, adopt high-grade HT300 gray casting machine body with integrated structure to ensure rigidity and stability.



Base

Double layered box-type base .The base feet are designed with trapezoidal structureto make to ensure good stability and machining accuracy.



Spindle box

Spindle box adopts box-type mechanism design, which is more rigid than normal design.


Germany linear guideway

Germany Rexroth brand linear guide way, higher rigidity, accuracy, and surface finish.


Double nut ball screw 

C3 level high speed ball screw with pre-extension process to reduce thermal elongation caused by heat distortion.



Spindle


The taper and end face of the BBT40 spindle is more closely attached to the tool holder, which ensures high rigidity for tools under heavy cutting machining.




Spindle bearing

BBT40 spindle with ceramic bearing, which is of better precision, rigidity and smoothness compared with BT40 ball bearing.


Spindle motor

Short nose spindle with 11/15kw spindle motor, higher torque to ensure rigid tapping, increase productivity.





COMPANY PROFILE
 

Dongguan Baoke Precision Machinery Co.,Ltd. is co-founded by Taiwan Baofeng and elites in Mainland China who engages in developing, manufacturing, selling and service of CNC machine centers. Our mainland manufacturing base is established in 2010, Baofeng has become a leading company for high-end machine center manufacturer in china as well as an integrated intelligent solution provider.

Machine scope includes various vertical machining center (linear guideway and square guideway), high speed engraving and milling machine, double column machining center and CNC tapping center.

At present, Baofeng has complete sales and after-sales service team across the country, but we try to bring our philosophy to the world and become a strong and competitive global player. We are now looking for partners overseas to build our dealers network and the same time preparing our local representative office.

Looking into the future, we will always committed to our culture "To be the first brand in industry, keep the principle of integrity" oriented by market and customer's needs, to provide high efficiency and high quality products and services.



Quality Control

From production to delivery, strict testing are adopted to inspect the static and dynamic accuracy of the machine, so as to ensure the accuracy and stability of BAOFENG machine.


Precise grinding: After milling process, all guideway mounting surface has gone through grinding process by imported CNC grinding machine (Normal machine body manufacturing only have milling process)


Manual scrapping: All joint surfaces of the machine body are manually scraped to ensure geometric accuracy and rigidity.


Standard and Strict process: Complete machine production procedure with high standards, all process could be tracked to ensure high quality. Even the torque of each screw will be tested and recorded.




Quality Assurance Syetem
1. G-TECH dynamic balancing inspection  
Spindle motor has gone through dynamic balance vibration detection and correction.

1. Renishaw Ballbar inspection

Inspect the roundness in the three planes (XY, XZ, YZ) of the machine, which can minimize the dynamic accuracy tolerance and improve the geometric accuracy.

3. Renishaw laser interferometer inspection
When detecting the screw pitch error, the straightness of the linear guide rail in the XX and YY directions can be checked at the same time to ensure the machining and assembly accuracy of the machine tool, meanwhile, can test the actual positioning accuracy and repeat positioning accuracy of the machine tool.

4. Germany Carl Zeiss CMM test
To check the precision of precision parts of machine tools, such as bearing caps, glands, motor flange plates, spindles, etc., as well as the geometric accuracy and surface tolerances of the test-cut samples.
 

1. Running test

In order to ensure quality, the machine will go through other quality control procedures, such as spindle vibration noise inspection, 72-hour full-function running-in test, etc.
