The milling machine is a machine tool for milling the workpiece with a milling cutter. In addition to milling planes, grooves, gears, threads and spline shafts, milling machines can also process more complex profiles, the efficiency is higher than the planer, in the machinery manufacturing and repair departments are widely used.
Problem 2: what is the milling machine milling machine (millingmachine) refers to the main milling cutter in the workpiece processing various surfaces of the machine tool. Usually the milling cutter rotary movement as the main movement, the workpiece (and) the movement of the milling cutter for the feed movement. It can process the plane, groove, but also can process a variety of curved surfaces, gears and so on. Milling machine is the use of milling cutter on the workpiece milling machine tool. In addition to milling planes, grooves, gears, threads and spline shafts, but also to process more complex surfaces, higher efficiency than the planer, in the machinery manufacturing and repair departments are widely used. Milling machine is a widely used machine tool, in the milling machine can be processed plane (horizontal, vertical), groove (keyway, T-shaped groove, dovetail groove, etc.), gear parts (gears, spline shafts, sprockets, good, spiral surface (threads, helical grooves) and a variety of curved surfaces. In addition, it can also be used for the surface of rotating bodies, internal hole processing and cut-off work. Milling machine in the work, the workpiece mounted on the table or indexing head and other accessories, milling cutter rotation as the main movement, supplemented by the table or the milling head of the feed movement, the workpiece can be obtained the required processing surface. Because it is a multi-tool intermittent cutting, thus the productivity of the milling machine is high. Milling machine tool with milling cutter on the workpiece for milling processing. Milling machine in addition to milling planes, grooves, gears, threads and spline shafts, can also process more complex surfaces, higher efficiency than the planer, in the machinery manufacturing and repair departments are widely used.
Question 3: What is the milling machine Milling is a kind of machining, in the milling machine can be processed on the plane (horizontal, vertical), groove (keyway, T-shaped groove, V groove, dovetail groove, etc.), tooth parts (gears, spline shafts, sprockets, sprocket wheel good, spiral surfaces (threads, helical grooves) and a variety of curved surfaces. Such as ball and socket. In addition, it can also be used for the surface of the rotating body, internal hole processing and cut-off work. Can also be profiling, such as cams.

Question 6: What does a miller do Drilling and milling is based on the design of parts drawings with a milling machine (equipment for machining parts) for parts processing of skilled workers, divided into junior workers, senior workers. Parts processing precision requirements.
Question 7: What is CNC milling machine CNC milling machine is a general milling machine on the basis of the development of a kind of automatic processing equipment, the two processing technology is basically the same, the structure is also somewhat similar. CNC milling machine is divided into two categories without tool magazine and with tool magazine. One of the CNC milling machine with tool magazine is also known as the machining center.
1, the adaptability of parts processing, good flexibility, can process the contour shape is particularly complex or difficult to control the size of the parts, such as mold parts, shell parts, etc.;
2, can be processed by ordinary machine tools can not be processed or very difficult to process parts, such as mathematical models described in the complex curves of the parts as well as three-dimensional surfaces of the parts;
3, can be processed at a time. Clamping and positioning, the need for multi-processing parts;
4, high processing accuracy, stable and reliable processing quality, the pulse equivalent of the CNC device is generally 0.001mm, high-precision CNC system up to 0.1μm, in addition, CNC machining also avoids the operator's operational errors;
5, the production of high degree of automation, which can reduce the operator's labor intensity. . Beneficial to the automation of production management;
6, high production efficiency, CNC milling machine generally do not need to use special fixtures and other special process equipment, in the replacement of the workpiece only need to call stored in the CNC device in the machining program, clamping tooling and adjustment of tooling data can be, and thus greatly shorten the production cycle. Secondly, CNC milling machine has the function of milling machine, boring machine, drilling machine, so that the process is highly concentrated, greatly improving the production efficiency. In addition, the spindle speed and feed rate of CNC milling machine are stepless variable speed, so it is conducive to the selection of the optimal cutting dosage.
Question 8: What does a CNC milling machine do? Milling is mainly processing plane parts, turning is mainly processing shaft parts.
Question 9: What is the difference between a horizontal milling machine and a vertical milling machine? What do they do? Shaft position is different, horizontal spindle horizontal arrangement, vertical spindle vertical arrangement, in addition to the spindle arrangement is different, their processing range is also different, the horizontal more disk milling cutter, can be used to support the auxiliary, the stiffness is relatively good.
Vertical milling machine with a relatively flexible milling cutter, a wider range of applications. Can use end mills, machine-clamped cutter disk, drills and so on. Can mill keyways, milling planes, boring, etc.. Horizontal milling machine can also be used above a variety of tools, but not as convenient as vertical milling, mainly can use the bracket to enhance the strength of the tool (mainly three-face edge milling cutter, chip milling cutter, etc.). Can milling slots, milling planes, cut off, etc..
Horizontal milling machine generally with vertical milling head although this vertical milling head function and rigidity is not as strong as the vertical milling machine, but enough to cope with vertical milling processing. This makes the overall function of the horizontal milling machine is more powerful than the vertical milling machine. Vertical milling machines do not have this feature and cannot process workpieces that are suitable for horizontal milling. Productivity is higher than horizontal milling machines. Vertical milling machine is a general-purpose metal cutting machine tool. The spindle taper hole of the machine tool can be directly or through the attachment to install a variety of cylindrical milling cutters, molding milling cutters, face milling cutters, angle milling cutters and other tools.
