Milling Machine and Milling Technology
Milling refers to the use of rotating multi-edge tools to cut workpieces, and is a highly efficient processing method. When working, the tool rotates (does the main movement), and the workpiece moves (the feed movement). The workpiece can also be fixed, but the rotating tool must also move (to complete the main movement and the feed movement at the same time). The machine tools used for milling are horizontal milling machines or vertical milling machines, as well as large portal milling machines. These machine tools can be ordinary machine tools or CNC machine tools. Use a rotating milling cutter as a cutting tool. Milling is generally performed on a milling machine or a boring machine. Suitable for processing plane, grooves, various molding surface (flower key, gear and thread) and special shaped surface of the mold and the like.
Milling is a machining method in which a milling cutter is used as a tool and the surface of an object is processed by CNC. Milling machines include horizontal milling machines, vertical milling machines, portal milling machines, profiling milling machines, universal milling machines, and bar milling machines.
What is milling?
Milling refers to the use of rotating multi-edge tools to cut workpieces, and is a highly efficient processing method.

Features of milling tools
① Each tooth of the milling tool periodically participates in intermittent cutting.
② The cutting thickness of each milling cutter tooth changes during the cutting process.
③ The feed per tooth αf (mm/tooth) indicates the relative displacement of the workpiece within the time that the milling cutter rotates one tooth.
Common milled parts
(1) Flat parts
The characteristics of plane parts: the machined surface can be parallel to the horizontal plane, perpendicular to the horizontal plane, or a fixed angle with the horizontal plane;
Most of the parts processed on the CNC milling machine are flat parts, and the flat parts are the simplest type of parts in CNC milling. Generally, only two-axis linkage or 3-axis linkage of a three-axis CNC milling machine can be used for processing. In the processing process, the processing surface and the tool are in surface contact, and end milling cutter or ball end milling cutter can be used for rough and finishing processing.
(2) Special-shaped parts with curved surfaces
The characteristic of curved parts is that the machined surface is arc-shaped space curved surface. During the machining process, the machining surface and the milling cutter are always in point contact. Surface finishing is mostly carried out with ball-end milling tools.
Precision correction of milling machine
X-axis correction of milling machine
Slightly loosen the 4 bolts, but make sure that there is still some friction resistance on the 4 bolts. At this time, use the rotating bolt of the head to adjust the left and right angle. During the process, a dial indicator must be placed on the end of the spindle to measure the correct position of the worktable.
Y-axis correction of milling machine
Slightly loosen the 3 bolts, but make sure that the 3 bolts are not too loose to facilitate fine-tuning. At this time, by the arm rotating bolt, a dial indicator placed on the spindle end in order to measure the correct position of the table.
Horizontal correction of milling machine
Place the spirit level on the work surface.
Check point A and B of the level, the allowable value is 0.06mm/m.
If necessary, shims can be placed under the machine.

The CNC milling machine can process complex shapes of rotating bodies. In milling, the blank is first fixed, and a high-speed rotating milling cutter is used to move the blank on the blank to mill out the required shape and features. Traditional milling is mostly used to mill simple shape features such as contours and grooves. The CNC milling machine can process complex shapes and features. The milling and boring machining center can perform three-axis or multi-axis milling and boring processing for processing: molds, inspection tools, molds, thin-walled complex curved surfaces, artificial prostheses, impeller blades, etc. When choosing CNC milling parts, the advantages and key functions of CNC milling machines should be fully utilized.

Choose the right tool for CNC machining parts
When finishing large parts, in order to ensure that at least one pass is completed and to avoid changing the tool in the middle of cutting, the tool life should be determined according to the accuracy of the part and the surface roughness. Compared with ordinary machine tool processing methods, CNC machining puts forward higher requirements on cutting tools. It not only requires good steel and high precision, but also requires stable dimensions, high durability, and easy installation and adjustment for breaking and discharging performance, so as to meet the high efficiency requirements of CNC machine tools.
CNC machine tools in processing aircraft parts
When machining on a CNC machine tool, manual tool control is not required, and the degree of automation is high. The benefits are obvious.
⑴ Reduced technical requirements for operators:
A senior worker of ordinary machine tools cannot be cultivated in a short time. However, the training time for a CNC employee who does not need programming is very short (for example, a CNC lathe worker only needs one week, and he will write simple processing programs). In addition, the parts processed by CNC workers on CNC machine tools have higher precision than those processed by ordinary workers on traditional machine tools, and it takes less time.

The main properties of stainless steel
The workability is much worse than that of medium carbon steel. Taking the machinability of ordinary No. 45 steel as 100%, the relative machinability of austenitic stainless steel 1Cr18Ni9Ti is 40%; The relative turning workability of ferritic stainless steel 1Cr28 is 48%; Martensitic stainless steel 2Cr13 is 55%. Among them, austenitic and austenitic + ferritic stainless steels have the worst machinability.
