What are the types of milling machines
Milling machine is a machine tool for milling and processing with milling cutters.In addition to being able to milling planes, grooves, wheel teeth, threads, and flower keys, it can also process more complex facial surfaces. The efficiency is higher than the plans. It is widely used in the mechanical manufacturing and repair departments.
The earliest milling machine was the American -owned horizontal milling machine created in 1818; in order to milling the spiral groove of the tingling drill, American Brown created the first universal milling machine in 1862, which is the prototype of the lifting table milling machine; in 1884A semi-automatic milling machine appeared in the 1920s of the 2020s, and the workbench used the gear to complete the automatic transformation of the feed-decisive or decisive or decisive-decisive-decisive-in-the-purpose automatic conversion.
After 1950, milling machines developed rapidly in the control system, and the application of digital control greatly increased the degree of automation of milling machines.Especially after the 1970s, the digital control system and the automatic knife system of the micro -processing machine were applied to the milling machine, which expanded the processing range of the milling machine and improved the processing accuracy and efficiency.
There are many types of milling machines. Generally, they are distinguished in the form of layout and the scope of applications. The main inclusions are littering and milling machines, dragon door milling machines, single -column milling machines and single -arm milling machines, instrument milling machines, tool milling machines, etc.
The lifting table milling machine has a universal, horizontal and vertical type, which is mainly used for processing small and medium -sized parts, the most widely used; Longmen milling machines include Longmen milling beds, dragon door milling machines, and double -column milling machines.The horizontal milling head of the column mill can be moved along the pillar guide rail, and the workbench is used as a vertical feed. The vertical milling head of the single -arm milling machine can be moved horizontally along the cantilever rail, and the cantilever can also adjust the height along the column guide rail.Both single -pillar milling machines and single -arm milling machines are used for processing large parts.
The instrument milling machine is a small lifting table milling machine, which is used to process the instrument and other small parts; the tool milling machine is mainly used for mold and tool manufacturing.Drilling, scooping and intercepting.Other milling machines also include key slot milling machines, cam milling machines, crankshaft milling machines, rolls axle and milling machines, and square steel ingot milling machines. They are all special milling machines manufactured for the corresponding workpiece.
Security rules
1. The loading and unloading workpiece must be removed. The head and hands must not be close to the milling noodles.
2. When using the Xu Zheng milling machine, you must slowly enter or shake in your hands. You are not allowed to move in. When you walk, you are not allowed to stop.
3. Pay attention to whether the handle of the Xu Zheng milling machine will hit when quickly entering the knife.
4. The knife is not allowed to be too fast, and it is not allowed to change suddenly.
5. The upper and lower and measured workpieces, adjusting the tool, and tightening change must stop the Xu Zheng milling machine.
6. Disassemble the vertical milling cutter. The work table should be padded with wooden boards, and the milling cutter is removed.
7. It is strictly forbidden to touch the hand or knife with a cotton yarn, and prohibit the knife tray with your hands.
8. In general, a jack can only be clipped at a time.Because one or more workpiece is clipped at a time, even if the clip is tight, it is very strong when the knife is rough, and the two workpieces are easy to slide, causing the workpiece to fly out, the knife is broken, and the injury is injured.
Maintenance
The scope of homework operation of milling machine milling machine
1. Clean work of bed and components, cleaning iron dandruff and surrounding environmental hygiene;
2. Check out the oil planes, not below the oil label, and add lubricating oil in all parts;
3. Moisturizers, clamps, and quantity.
The scope of the operation of milling machine
1. Clean and adjust the workbench, screwpad and pillar inlaid;
2. Check and adjust the clutch;
3. Clean the three -way guide track and oily felt, the inside and outside of the motor, the inside and outside of the machine, and the attachment clean;
4. Check the oil road and add the lubricating oil;
5. Tighten the screws of each ministry.
The scope of the exercise of milling machine insurance
