There are many kinds of CNC lathes in different sizes. The types of modern machine models are almost infinite. Some CNC machines are small enough to be mounted on the workbench, while others are large enough to be accommodated by building special workshops. Some CNC machine tools are very simple, while others are very complex in structure and operation. What are the basic machining methods in machining? What are the characteristics of different processing methods?
No matter the CNC machine tools are large or small, simple or complex, they can be divided into five categories. These five categories are the five basic methods of metal forming. CNC precision machining includes: drilling, turning and boring, milling, grinding and shaping. The characteristics of these treatment methods are as follows:
1. Drilling
Drilling is the process of drilling holes in solid metal using a rotary bit called a fried dough twist drill. CNC lathe used for drilling is called drilling machine. There are also many kinds and specifications of drilling machines. In addition to drilling, the drilling machine can also perform other processing. When drilling, the workpiece is clamped and fixed. The drill bit rotates while drilling into the workpiece.
2. Turning
The general lathe is the most commonly used machine for turning parts. Turning is the removal of metal from a workpiece. When the workpiece rotates, the tool cuts along the workpiece.
Boring is a method of enlarging or further processing holes drilled or cast in metal workpieces. Boring on the lathe is completed by a single edge tool, which rotates while feeding the workpiece.
3. Milling
Milling is the process of turning tools to cut metal. This kind of cutter has multiple cutting edges and is called milling cutter.
4. Grinding
Grinding is a method of removing metal using a wheel called a grinding wheel. The workpiece is finished by grinding. The workpiece size after grinding is accurate and smooth. When grinding a circular workpiece, the workpiece rotates and feeds the rotating grinding wheel. When grinding a flat workpiece, the workpiece moves back and forth while the grinding wheel rotates. Grinding process is to finish the hard workpiece after heat treatment to achieve accurate size.
5. Shaping
Single blade cutter is used for air gouging, gantry cutting and grooving machine precision plane. When the forming machine is used for processing, the workpiece feeds the cutter and the cutter moves back and forth on the workpiece. When using gantry cutting, the tool cuts or feeds the workpiece, and the workpiece moves back and forth under the tool.
6. Slotting processing is similar to shape processing. Grooving machine is actually a vertical forming machine, mainly used to cut certain types of gears.
