CNC milling machine is an automatic processing equipment developed on the basis of general milling machines. Although different types of CNC milling machines have differences in composition, they have many similarities. Design of the processing route for CNC milling machines must comprehensively consider various factors, pay attention to the correct division and sequence of processes, and arrange the connection between CNC milling processes and ordinary processes reasonably. In the division of processes, it is necessary to flexibly grasp factors such as the structural requirements of the workpiece, the installation method of the workpiece, the processing technology of the workpiece, the performance of CNC milling, and the production organization and management of the factory. Below, Yida Borun Petrochemical briefly introduces the selection of CNC milling machines and the method of process division:

1,The selection principles of CNC milling machines

(1) Select according to the size of the processed parts

A small-size lifting table CNC milling machine is most suitable for machining small and medium-sized parts and complex surface contour milling tasks on its workbench. Larger specifications such as gantry milling machines are used to solve the machining needs of large-sized complex parts.

(2) Select according to the precision requirements of the processed parts

China statuit standardes precisionis machinarum CNC milling, inter quas sunt standardes professionales CNC machinarum milling vertical, mensam milling machinarum elevans. Maquina CNC milling tipica optima machinae plurimarum parterum convenere potest. For parts with high precision requirements, precision CNC milling machines should be considered.

(3) Selekte secundum characteres processionis partium processionis

For machining parts with frames shaped planes or unequal altitudes of various levels of steps, a CNC milling machine with a point position linear system can be selected.

If the processing part is a curved surface contour, the selection of a two coordinate linkage and a three coordinate linkage system should be based on the geometric shape of the surface.

According to the machining requirements of the parts, a CNC indexing head or CNC rotary worktable can also be added to the general CNC milling machine. At this time, the machine tool system is a four coordinate CNC system, which can process spiral grooves, blade parts, etc.

(4) Select according to the batch size or other requirements of the parts

Pro multa quantitate, utilisatores militias specialisas utilizat. If it is a small to medium batch production with frequent periodic repetition, then using a CNC milling machine is very suitable because many fixtures, programs, etc. are ready in the first batch to be stored and reused.

In longo tempore non est inevitabile ut militiae machinarum in alto nivelo automaticae substituent militias ordinaras machinas, reducant opus laboris et improvint productivitatem.

2、 The division of machining processes in CNC milling

(1) Divide the process based on clamping positioning. Haec methodo generale est ad opera partibus cum continentibus processionis, prima partem processionis in pluribus partes, sicut interiorem cavitatem clampsimum dum numericam controlum militiam et exteriorem cavitatem clampsimum per machinas.

(2) Divide the process into rough and fine machining. For CNC milling parts that are prone to machining deformation, considering factors such as machining accuracy deformation of the workpiece, the process can be divided according to the principle of separating rough and fine machining, that is, first rough and then fine.

(3) In reductione numeri variationum instrumentorum, principum concentrationis instrumentorum acceptum potest dividere processum. Prioritizat utilizacionem instrumentorum intercessionis centralisae potest reducere frequencatem variationum instrumentorum frequentarum, currit viam instrumentorum, et sic improvit efficabilitatem machinarum.

3,Selection of specialized cutting oil

Special cutting oil is a medium that must be used in CNC cutting technology, which mainly plays a role in lubrication, cooling, cleaning and other functions during the machining process.

(1) The specialized cutting oil contains sulfurized extreme pressure and anti-wear additives, which can effectively protect the cutting tools and improve process accuracy.

(2) Compared with rapesed oil, mechanical oil, and recycled oil, specialized cutting oil has good stability and will not cause harm to equipment, human health, or the environment.

(3) The specialized cutting oil has passed strict tests in viscosity, flash point, pour point, thermal conductivity, and other aspects to meet various cutting process requirements.

CNC milling machine processing has achieved standardization of processing information and is currently organically integrated with computer-aided manufacturing, which is the foundation of modern integrated manufacturing technology. Yida Borun Petrochemical is the largest producer of high-end metal processing oil in China. Its independently developed gear cutting oil products have excellent extreme pressure and wear resistance performance, which can effectively improve the accuracy and processing efficiency of gear workpieces, and are not harmful to human body, workpieces, equipment, or the environment. It is a designated partner for many domestic metal processing enterprises and has received unanimous praise from domestic and foreign customers in practical applications.
