CNC Vertical Machining Center [BVMC-850]

Product Description

CNC Vertical Machining Center [BVMC-850]

1)Casting is made by advanced nano Meehanite. Such material is very stable; It can make sure there is no distortion after long term use. Main structure adopts ANSYS limited unit software analysis, to reach highest and best rigid structure design.

2)We design strong structure to build column, avoid and reduce distortion while cutting.

3) Nut integrated design
Nut block for screw and main machine body are built together for every axis, with this design, machine will get better rigidity, and won't lost precision while heavy cutting and acceleration movement impact

4)Adopt three slide blocks for single axis
Adopt three slide blocks for single axis will enhance load capacity around 30%, with this method will improve the load capacity.

5)Optimized structure of heavy rail linear guide
Comparing with ball screw guide, its lead capacity and damping properties has been improved 30% and 15% respectively: Comparing with hard track guide, dynamic motion function has been improved 300%, at the same condition, the machining efficiency will be 2%-15% better, life of machine will be 3-6 times longer, so without shutting the machine down to repair, it will save 5-20% precious time

6) High accuracy, high inflexible principal axis
Belt transmission type principal axis can provide biggest RPM8000-12000. Special designed principal axis bear configuration, show us the outstanding rigidity of principal head.
Precious ball screw assembly is adopted for X, Y and Z axis, such screw is pre-processed to ensure best precision and minimize the error.

7)Disc style ATC system

8). Advantage of system
1. MITSHBISHI choose 64bite high speed CPU and PLC as the heart if control system, not only improve data processing speed, but also raise machining efficiency obviously.
2. Most advanced hardware is adopted, it is advantage to enhance the ability of high speed processing and the ability of compensation,
3. System support various language and can be used worldwide.
4. Principal axis is connected by parallel bus.
Servo system
Swift response and stable location loop control system will be most beneficial while machining process, it also realize stable control of speed up and speed down.
1. Adoption of the medium and small model servo motor and high-resolution decoder
2. Enhance the rigidity of machine tool
3. Special characteristics in stable control of speeding up and down
4. Reduce parts processing time and improve the machining precision of parts.
