CNC machining technology is an advanced manufacturing technology, which uses computer technology to control machine production. The core part of this technology is the unique software and console of computer.

 

The CNC machining center is classified according to the space location of the main shaft processing: Horizontal and Vertical machining centers, which are classified according to the process use: Boring Milling Processing Center, Composite Processing Center, according to the special classification of functions are: Single Working Table, double working table and multi-working table processing center. CNC machining center, according to the processing accuracy score: Has the General Processing Center and the High Precision Processing Center.

 

First of all, Horizontal Machining, also known as milling, relies on rotary cutters to remove metal from a workpiece. Horizontal machining occurs on a horizontal machining center (HMC), which employs a spindle that is parallel to the ground floor. With a horizontally oriented spindle, tools stick out of the side of the tool holder and cut across the side of a workpiece, encouraging chips to fall away from the table. Horizontal machining centers also allow for two-pallet changer integration to facilitate unattended operation and reduce part cycle times. And Vertical Machining, also known as milling, relies on rotary cutters to remove metal from a workpiece. Vertical machining occurs on a vertical machining center (VMC), which employs a spindle with a vertical orientation. With a vertically oriented spindle, tools stick straight down from the tool holder, and often cut across the top of a workpiece.

 

The machine adopts 800*800 mm double - switch worktable, which can't only process the larger parts, but also can rotate separately. It is most suitable for milling, boring, tapping, two - dimensional and industries.


In order to improve the machining efficiency and machining precision of the complex heterogeneous products, the craftsmen have been looking for more efficient and precise processing methods, the appearance of composite processing equipment has provided an effective solution for improving the machining precision and efficiency of aerospace parts, one is the combination of different methods of processing based on energy or motion mode; the other is a mechanical process-based composite based on the principle of concentration of processes, milling Compound machining is one of the fastest developing processing methods in this field in recent years.

 

From the Special Function of NC machining center, the number of worktable is controlled by the instruction of the numerical information. It is determined by the actual production. Smaller workloads or simpler operating processes can be produced by choosing single workstations, large workloads and complex production. Consider choosing a double or composite workbench. No matter which way is adopted, its comprehensive processing ability is very strong, the work piece after one time can finish more processing content. It has high machining accuracy and is 5-10 times more efficient than conventional equipment in terms of medium processing difficulty, especially when it can complete the processing which many common equipment can not complete, and is more complex to the shape, single-piece processing with high precision or small and medium-sized multi-species production is more suitable.

 

The general machining center has a resolution of 1 m, the maximum feed speed is 15 ~ 25 m / Min and the positioning accuracy is about l0 m. The high precision machining center, the resolution is 0.1 m, the maximum feed speed is 15 ~ 100 m / Min and the positioning accuracy is about 2 m. Between 2 ~ L 0 M and 5 m more, it can be called the precision level. However, they can be processed with stable quality, high machining accuracy, and can process complex surfaces that are difficult to process, and can even process parts of the process that can not be observed.

 

So, in general, the different classification of NC machining technology is based on different actual production conditions. The precision machining of manufacturing industry can not be separated from NC machining technology, and it is believed that there will be more development space in the future.
