What is a drilling milling machine
Drilling and milling machine is a small and medium-sized universal metal cutting machine tool, which can both horizontal milling and vertical milling. It is a general milling machine. The drilling and milling machines have a wide range. Machining machines mainly with drilling and milling functions can be called drilling and milling machines. Drilling and milling machine is a machine tool equipment integrating drilling, milling, tapping, boring and grinding. It is suitable for processing all kinds of small and medium-sized parts, especially non-ferrous metal materials; Plastic; Nylon cutting has the advantages of simple structure and flexible operation. It is widely used in single piece or batch mechanical manufacturing; Instrument industry; Architectural decoration and repair department.
It is suitable for drilling, expanding, tapping, reaming, boring and hole processing; For example, disc milling machine, angle milling cutter, forming milling cutter and vertical milling cutter can mill plane, inclined plane, vertical plane and groove. After the accessory vertical milling head is installed, it can be used for multi-directional milling. After the accessory dividing head is installed, it can be used for milling straight teeth, bevel gears and spiral teeth with a mold number of less than 3 mm The drilling and milling machine can not only complete the drilling and reaming of workpieces possessed by the drilling machine, but also complete the processing of plane and inclined plane of various workpieces. This kind of equipment is widely used.
The drilling and milling machine is a workbench that can move vertically and horizontally, and the spindle is arranged vertically. It is usually a desktop, and the head can rise and fall up and down. The spindle box can rotate 90 ° left and right in the vertical plane, and the worktables of some models can rotate 45 ° left and right in the horizontal plane. The worktables of most models can automatically feed the tool longitudinally.The structure of drilling and milling machine is composed of nine main parts: bed, base, triangle, worktable and sliding seat, sliding arm rotating seat, milling head, cooling and lubrication, electrical system and so on. The guide rail pair of the worktable is ground after ultra audio frequency quenching, with higher precision. The vertical spindle sleeve has manual and micro feed.
The bed is installed on the base, and the main motor is installed in the lower abdomen of the bed. It is transmitted to the I shaft through a pair of V-belt pulleys, enters the gear box of the bed, and is transmitted to the main shaft through six pairs of gears. The front end of the main shaft is Mohs No. 4 conical hole. Either the end milling tool handle or the tool bar can be installed. The other end of the long tool bar is supported in the bearing hole of the hanger, and the tool bar support is installed on the dovetail guide rail of the sliding arm.
The difference between milling machine and drilling and milling machine in structure: milling machine is mainly driven by gear. The drilling and milling machine mainly depends on the transmission of belt. The cutting capacity of milling machine is much larger than that of drilling and milling machine. The clamping tool range is also large and wide. Therefore, the processing capacity and scope are also large. Drilling and milling machines can only do some simple milling work. It is far from the function of the milling machine. The milling machine has an vertical milling head or a universal milling head. The direction of the milling head can rotate, but the milling head of the drilling and milling machine is dead and cannot move. The power of gear transmission is large and it is not easy to get stuck. It doesn’t matter if you eat a lot of tools. The belt driven tool is too small to feed. If you feed a little more, the tool will stop.
Turret milling machine is a kind of drilling and milling machine. In short, drilling and milling machine includes turret milling machine. Turret milling machine can also be called rocker milling machine, rocker milling, universal milling. The turret milling machine has the advantages of compact structure, small volume and high flexibility. The milling head can rotate 90 degrees left and right and 45 degrees back and forth. The rocker arm can not only stretch back and forth, but also rotate 360 degrees in the horizontal plane, which greatly improves the effective working range of the machine tool.
Drilling and milling machine can be equipped with automatic feed, dro, universal dividing head, rotary table, vice, clamping kit, etc. These devices greatly improve the working efficiency and application range of the drilling and milling machine. If you need a fully functional milling machine to process small and medium-sized parts, drilling and milling machine is a good choice. There are also CNC drilling and milling machines on the market.

What are the main matters and steps to use the drilling and milling machine? Check out some tips below.
- 1.First, check the empty position of the oil filling of the drilling and milling machine. Generally, it is at the top of the gearbox of the drilling and milling machine. Unscrew the oil plug, add lubricating oil and lithium grease, and add 2 / 1 of the oil window!
- 2.Install the power cord to keep the drilling and milling machine powered on normally (the machine tool must be grounded!)
- 3.Turn on the power supply, first use the work light to check whether it works normally, and then check whether the variable speed handle of the drilling and milling machine is combined completely according to the indication. After all checks, jog the spindle switch of the drilling and milling machine. After the sound is normal, you can start up and test run normally!
- 4.Steps for using the drill chuck: first, clean the oil and other residues in the inner hole of the spindle of the drilling and milling machine with a clean cotton cloth dipped in gasoline, then scrub the spindle extension rod, install it together with the drill chuck, gently install it into the inner hole of the spindle of the drilling and milling machine, tighten it with a 14mm diameter pull rod, clamp the drill bit, and then drill!
- 5.Use of milling chuck of drilling and milling machine: firstly, clean the oil and other residues in the inner hole of the spindle of drilling and milling machine with clean cotton cloth dipped in gasoline, and then scrub the main body of milling chuck, select the chuck of milling chuck to be used, put it into the chuck, unscrew the lock nut of milling chuck, put the chuck into the lock nut, and screw the lock nut to realize the operation function of milling keyway!
- 6.How to bore the drilling and milling machine: first, clean the oil and other residues in the spindle hole of the drilling and milling machine with a clean cotton cloth dipped in gasoline, install the boring bar into the inner hole of the drilling and milling machine, there is a square hole at the bottom of the boring bar, and install the boring cutter to realize the boring operation!
- 7.Drilling and milling machine how to tap: find a medium speed, select the spindle speed according to the tapping diameter, and use forward and reverse to realize tapping operation.(Note: no matter how to operate, the workpiece must be tightened to avoid serious consequences caused by workpiece rotation)
- 8.Maintenance of drilling and milling machine:
After using the drilling and milling machine for the first time for one month, replace the lubricating oil once, and keep the overall cleanliness of the machine tool. Before going off work every day, clean the guide rail of the drilling and milling machine once with a clean cotton cloth, and then apply engine oil to prevent rust!, At the hand wheel of the drilling and milling machine and the worktable of the drilling and milling machine, inject oil every shift to keep the hand wheel of the drilling and milling machine lubricated and prolong the service life of the drilling and milling machine. Whenever the machine tool is found to be faulty, it shall be stopped immediately for inspection, reported to the technology department and sent a professional mechanic for repair. Clean up after work and turn off the power supply.
