1.Different working principles
Drilling machine is the drill bit as the main processing tool, using the way of rotating friction to cut the workpiece. When the drill rotates at high speed, the material in the hole of the metal workpiece is gradually whittled away to form the hole of the desired size and shape. It occupies a small area and has a slightly single function.
The milling machine uses the milling cutter as the main processing tool to cut or process the surface of the workpiece into the desired shape and size by rotating the milling cutter. The structure of the milling machine is varied, and the common ones are turret type and gantry type milling machines. Turret type milling machine has obvious structural advantages, simple structure, easy to operate, convenient, mainly for some small parts drilling and processing, not suitable for large parts processing. However, the gantry type milling machine makes up for the shortcomings of the turret type milling machine, it can process large parts and accessories, and adds the function of digital control, and does not need people to stand next to the operation of the machine tool, which is widely respected by customers.
2.Different processing methods
The drilling machine can only carry out simple linear drilling, and can not surface processing of the workpiece, while the milling machine can carry out a variety of processing methods, such as plane milling, three-dimensional milling, chamfering, slotting, etc. The milling machine allows the workpiece to be cut in multiple directions, with greater freedom than the drilling machine.
3.Different rigidity
The main processing method of the drilling machine is to apply pressure to the parts from the top end, the vertical force is very large, and the lateral load capacity is weak. The milling machine can not only apply pressure to the parts from the upper end, but also apply pressure to the parts from the side, good rigidity, simply put, the side load capacity is very strong. This is the biggest difference between drilling machines and milling machines.
4.Rotate speed and accuracy
First, the accuracy of the milling machine is higher than that of the drilling machine. The milling equipment of the milling machine can be moved on three axes at the same time, with higher accuracy than drill press production. Secondly, because the size of the milling machine is large, the weight is heavy, and it is usually installed on the floor, so the milling machine can be applied to high speed. The drill machine usually uses a low speed, after all, the size and weight of the drill machine are relatively small, and it is usually placed on the table and manually operated.
5.Different application range
Drilling machine is usually used for some simple drilling operations, such as metal parts, wood, plastic products and other materials drilling processing. The milling machine can handle more complex processing tasks, such as milling, grooving, engraving of various metals and their composite materials.
In summary, there are obvious differences between drilling machine and milling machine in working principle, processing method, rigidity, rotate speed, accuracy and application range. In the choice of use, it is necessary to select the appropriate equipment according to the specific processing needs to achieve better results.
