The end face milling machine has a large processing range and is suitable for end face cutting of metal materials such as castings and steel parts, and is widely used in the machinery manufacturing industry. The end face milling machine is especially suitable for the plane milling of the mold industry and the frame of the plastic mold frame.
The face milling machine can mill the plane of the workpiece, chamfer the trapezoidal surface and the T-slot, the drilling can reach φ50mm, and the boring can reach φ400mm. After the support slide is installed, the two ends of the super-long workpiece can be milled, manually drilled, bored, and processed with special-shaped surfaces. The milling force is strong and can meet the processing requirements of the parts. The movement of the worktable adopts the planetary gearbox to change the speed, and the operation is flexible and easy. The lifting of the column adopts the counterweight unloading device, which can move up and down easily, which not only prolongs the life of the lead screw but also makes the cutting smooth.
(1) Process concentration
CNC machine tools generally have tool holders and tool magazines that can automatically change tools. The tool-changing process is automatically controlled by the program. Therefore, the process is relatively concentrated, reducing the floor space of the machine tool, saving the workshop, and reducing or no intermediate links (such as semi-finished products). Intermediate testing, temporary storage, handling, etc.), saving both time and manpower.
(2) High degree of automation
When CNC machine tools are processed, there is no need to manually control the tool, the degree of automation is high, and the requirements for operators are reduced. The parts processed by CNC operators on CNC machine tools have higher precision than those processed by ordinary workers on traditional machine tools, and save time and effort, reducing the labor intensity of workers.
(3) Product quality is stable
The processing automation of CNC machine tools eliminates human errors such as fatigue and carelessness of workers on ordinary machine tools and improves the consistency of products.
(4) High processing efficiency of face milling machine
The automatic tool change of CNC machine tools makes the processing process compact and improves labor productivity.
There are many types of face milling machines, which are generally distinguished according to the layout and scope of application.
① Lifting table milling machine: there are universal, horizontal, and vertical types, etc., mainly used for processing small and medium-sized parts, and is the most widely used.
②Gantry milling machine: including gantry boring and milling machine, gantry milling planer, and double-column milling machine, both of which are used to process large parts.
③Single-column milling machine and single-arm milling machine: the horizontal milling head of the former can move along the column guide rail, and the worktable is fed longitudinally; the end milling head of the latter can move horizontally along the cantilever guide rail, and the cantilever can also adjust the height along the column guide rail. Both are used for machining large parts.
④The worktable does not lift the milling machine: there are two kinds of jug-shaped working table and round table, which is a medium-sized milling machine between the lifting table milling machine and the gantry milling machine. Its vertical movement is completed by the milling head rising and falling on the column.
⑤ Instrument milling machine: a small lifting table milling machine for processing instruments and other small parts.
⑥Tool milling machine: used for mold and tool manufacturing, equipped with various accessories such as end milling head, universal angle table, and plug, and can also be used for drilling, boring, and plunging.
⑦ Other milling machines: such as keyway milling machines, cam milling machines, crankshaft milling machines, roll journal milling machines, and square steel ingot milling machines, etc., are special milling machines manufactured for processing corresponding workpieces.
According to the control mode, milling machines are divided into copy milling machines, program control milling machines, and digital control milling machines. Face milling machine lathe operators should pay attention to the following items when operating to avoid danger.
(1) Wear tight protective clothing, do not open the cuffs, wear protective caps for long hair, and do not wear gloves when operating.
(2) The loading and unloading of the chuck on the spindle of the machine tool should be carried out after the machine is stopped, and the chuck cannot be removed by the power of the motor.
(3) It is best to use a protective cover for the protruding parts of the chuck, dial, and heart clamp that hold the workpiece, so as not to entangle clothes and other parts of the body.
(4) When clamping the workpiece with the center, the center should be the same as the center hole, and the damaged or skewed center should not be used. The center and the center hole should be cleaned before use. The top of the rear tailstock should be firm.
(5) When turning slender workpieces, the center frame or the tool rest should be used to ensure safety, and the part that grows out of the lathe should be marked.
(6) When turning workpieces with irregular shapes, a balance block should be installed, and the balance should be tested before cutting.
(7) The tool should be clamped firmly, the protruding part of the tool head should not exceed 1.5 times the height of the tool body, the shape and size of the gasket should be consistent with the shape and size of the tool body, and the gasket should be as few and flat as possible.
(8) Except that the lathe is equipped with an automatic measuring device in operation, the workpiece should be stopped to measure and the tool rest should be moved to a safe position.
(9) For the strip-shaped chips and spiral-shaped long chips that have been cut, use hooks to remove them in time, and it is strictly forbidden to pull them by hand.
(10) A transparent baffle should be installed in a suitable position to prevent the chips from hurting people.
(11) When grinding the surface of the workpiece with emery cloth, move the tool to a safe position, and do not let clothes and hands touch the surface of the workpiece. When processing the inner hole, the emery cloth should not be supported with fingers, a wooden stick should be used instead, and the speed should not be too fast.
(12) It is forbidden to put tools, fixtures, or workpieces on the lathe bed and the spindle gearbox. There are mainly the following aspects:
Before using a face milling machine:
1. Check important parts.
2. After cleaning the exposed rails, lubricate all parts as required
3. Run dry and see if the lubrication system is normal.
