What does a milling machine do?

Question 1: What is the milling machine for? Milling machine refers to a machine tool that mainly uses milling cutter to process various surfaces on workpieces. Generally, the rotary motion of the milling cutter is the main motion, and the motion of the workpiece (and) the milling cutter is the feed motion. Can process planes and grooves, as well as various curved surfaces and gears.

Milling machine is a machine tool for milling workpieces with milling cutter. Milling machines can not only mill planes, grooves, gear teeth, threads and spline shafts, but also process more complex contours, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments.

Question 2: What exactly is a milling machine? Milling machine refers to a machine tool that mainly uses milling cutter to process various surfaces on workpieces. Generally, the rotary motion of the milling cutter is the main motion, and the motion of the workpiece (and) the milling cutter is the feed motion. Can process planes and grooves, as well as various curved surfaces and gears. Milling machine is a machine tool for milling workpieces with milling cutter. Milling machines can not only mill planes, grooves, gear teeth, threads and spline shafts, but also process more complex contours, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments. Milling machine is a widely used machine tool, which can process plane (horizontal plane and vertical plane), groove (keyway, T-groove, dovetail groove and so on. ), toothed parts (gears, spline shafts, sprockets), helicoids (threads, spiral grooves) and various curved surfaces. In addition, it can also be used to process the surface and inner hole of the rotary body and cut it off. When the milling machine is working, the workpiece is mounted on the accessories such as the workbench or the indexing head, and the rotation motion of the milling cutter is the main motion, supplemented by the feeding motion of the workbench or the milling head, so that the workpiece can obtain the required machining surface. Because it is multi-tool intermittent cutting, the productivity of milling machine is high. A machine tool for milling workpieces with a milling cutter. Milling machines can not only mill planes, grooves, gear teeth, threads and spline shafts, but also process more complex contours, with higher efficiency than planers, and are widely used in machinery manufacturing and repair departments.

Question 3: What does a milling machine do? Milling is a kind of machining. Plane (horizontal plane and vertical plane), groove (keyway, T-groove, V-groove, dovetail groove, etc. ), toothed parts (gears, spline shafts, sprockets, helicoids (threads, spiral grooves) and various curved surfaces can be machined on the milling machine. Such as a ball socket. In addition, it can also be used to process the surface and inner hole of the rotary body and cut off the work. You can also do copying processing, such as cams.

Safe operating procedure

1. Work clothes must be worn when entering the workshop. Gloves are not allowed to be worn during operation (to prevent gloves from hanging on the cutting knife and causing accidents), and female students must wear working caps (to prevent the hair from being caught in the machine because it is too long).

2. Before driving, check whether the handle position of the machine tool and the tool clamping are firm and reliable, and whether the tool movement direction and the feeding direction of the workbench are correct.

3. Fill all oil injection holes, idle for more than 2 minutes (you must drive slowly in winter), and check the oil window and other parts.

And listen to whether the sound is normal.

4. When cutting, start the car first. If you stop halfway, stop feeding first, and then stop after withdrawing.

Concentrate, stick to your post, stop when you leave, and the machine tool is not allowed to work overload.

Question 6: What does a miller do? Drilling and milling workers are skilled workers who process parts with milling machines (equipment for processing parts) according to the design drawings of parts, and are divided into junior workers and senior workers. The machining accuracy of parts is high.

Question 7: Why CNC milling machine? Some CNC milling machines are automatic processing equipment developed on the basis of ordinary milling machines. Their processing technology is basically the same, and their structures are somewhat similar. CNC milling machines can be divided into two categories: tool magazine and tool magazine. Among them, the CNC milling machine with tool magazine is also called machining center.

1, parts have strong processing adaptability and good flexibility, and can be used to process parts with particularly complex contour shapes or difficult to control dimensions, such as mold parts and shell parts;

2. It can process parts that ordinary machine tools can't process or are difficult to process, such as complex curve parts and three-dimensional curved parts described by mathematical models;

3. Parts requiring multiple processes can be processed by one-time clamping and positioning;

4. The machining accuracy is high, and the machining quality is stable and reliable. The pulse equivalent of the numerical control device is generally 0.00 1mm, and the high-precision numerical control system can reach 0.1μ m. In addition, the numerical control processing also avoids the operator's operation mistakes.

5. The high degree of production automation can reduce the labor intensity of operators. Conducive to the automation of production management;

6, high production efficiency, CNC milling machines generally do not need to use special process equipment such as special fixtures, and only need to call the processing program stored in the CNC device, clamp the tool and adjust the tool data when replacing the workpiece, thus greatly shortening the production cycle. Secondly, the CNC milling machine has the functions of milling machine, boring machine and drilling machine, which makes the working procedures highly concentrated and greatly improves the production efficiency. In addition, the spindle speed and feed speed of CNC milling machine are stepless, which is beneficial to choose the best cutting parameters.

Question 8: What does a CNC milling machine do? Milling workers mainly process plane parts, while turning workers mainly process shaft parts.

Question 9: What is the difference between a horizontal milling machine and a vertical milling machine? What do they do respectively? With different shaft positions, the horizontal spindle is arranged horizontally and the vertical spindle is arranged vertically. In addition to the different spindle arrangement, their processing range is also different. The horizontal multi-purpose disc milling cutter can assist the support, and its rigidity is relatively better.

The milling cutter of vertical milling machine is flexible and has a wide range of applications. End milling cutter, machine tool bit, drill bit, etc. Can be used. Keyway milling, plane milling, boring, etc. Horizontal milling machine can also use the above tools, but it is not as convenient as vertical milling machine. The main reason is that the hook can be used to enhance the strength of tools (mainly three-sided milling cutter, thin plate milling cutter, etc.). ). Slot milling, plane milling, cutting, etc.

Horizontal milling machines generally have vertical milling heads. Although the function and rigidity of this vertical milling head is not as strong as that of a vertical milling machine, it is enough to cope with vertical milling. This makes the overall function of horizontal milling machine more powerful than that of vertical milling machine. The vertical milling machine does not have this function, so it cannot process the workpiece suitable for horizontal milling. The productivity is higher than that of horizontal milling machine. Vertical milling machine is a universal metal cutting machine. All kinds of cylindrical milling cutters, forming milling cutters, end milling cutters, angle milling cutters and other cutters can be installed in the taper hole of the machine tool spindle directly or through accessories.
