Cause analysis:
After graduation, students majoring in numerical control are mainly employed in high-end equipment manufacturing such as power generation equipment manufacturing, military industry, aerospace, shipbuilding and data equipment manufacturing. Engaged in CNC machine tool operation, data processing programming, data processing technology preparation, product quality inspection, on-site management, production scheduling, CNC equipment sales and after-sales service.
The concept of CNC machine tools;
CNC lathe is one of the widely used CNC machine tools. It is mainly used for cutting internal and external cylindrical surfaces, internal and external conical surfaces with arbitrary cone angles, complex revolving internal and external curved surfaces, cylindrical surfaces and tapered threads of shaft parts or disc parts, and can be used for slotting, drilling, reaming and boring.
Features:
Compared with ordinary machine tools, CNC machine tools are characterized by high machining accuracy and stable machining quality. Multi-coordinate linkage can be carried out to process parts with complex shapes; When the machined parts change, it is generally only necessary to change the numerical control program, which can save the production preparation time; The quality of operators is required to be higher, and the technical requirements of maintenance personnel are higher.
Basic components of CNC machine tools;
1, economical CNC lathe
A simple NC lathe is formed by transforming the turning feed system of ordinary lathe with stepping motor and single chip microcomputer. Low cost, poor automation and function, and low turning accuracy. Suitable for turning rotary parts with low requirements.
2, ordinary CNC lathe
According to the requirements of turning, the structure is specially designed and equipped with a general CNC system to form a CNC lathe. The numerical control system has strong functions, high degree of automation and high machining accuracy, and is suitable for turning general rotary parts. This CNC lathe can control two coordinate axes at the same time, namely X axis and Z axis.
3, turning machining center
On the basis of ordinary CNC lathe, C-axis and power head are added. A more advanced machine tool also has a tool magazine, which can control three coordinate axes of X, Z and C. The linkage control axis can be (X, Z), (X, C) or (Z, C). Due to the addition of C axis and milling power head, the machining function of this CNC lathe is greatly enhanced.
