Drilling and tapping machine is a metal cutting machine tool and CNC machining equipment, with a style and function similar to a machining center, but slightly smaller than a machining center. Generally, the stroke does not exceed 800 * 400. Although it can be used for boring and milling, it cannot perform heavy load machining such as strong milling. It is mainly used for drilling and tapping. Usually, a turret type tool magazine is used, and the fast moving speed is generally faster than that of the machining center. Similar to machining centers, the spindle usually adopts a direct connection type, the tool library adopts a turret type, and the spindle taper is BT30. It is generally used for drilling and tapping, and can also be used for milling and boring. The rigidity of the whole machine is weaker than that of the machining center, but the speed is faster!
Drilling and tapping machines can mass produce and process small hardware parts, such as drilling, tapping, and milling. Therefore, the rotational speed is relatively fast, resulting in rough threads. The rotational speed of the tapping machine is relatively slower, so the threads produced are relatively smooth. Drilling and tapping machines are mostly desktop machine tools, mainly used for drilling, tapping, and chamfering. The machining center has additional functions such as milling and grinding.
The drilling and tapping machines mainly include commonly used models such as T5, T6, and T7. They are all high-speed drilling and tapping machines designed for the 3C industry, with high speed, efficiency, precision, and reliability as their main characteristics. Their main advantages are special spindles and high bearing rigidity; Spindle 20000/24000/rpm, 21T tool magazine; Widen the saddle and ensure the stability and weight of the herringbone column; The main engine weighs 3.3 tons, which is more than 50% higher than its peers; Autonomous T80 system, safety guarantee, unrestricted control of more than 5 axes.
When choosing a machine tool model, we first need to understand the material, size, and required accuracy of the workpiece we need to process. Only with a clear understanding can we better choose the machine tool model that suits us. What to pay attention to when choosing a milling machine:
1. The size of the workbench and the stroke parameters of the spindle X/Y/Z;
2. Machine Tool Type: Determine whether the structure of the workpiece being processed is long or short guided
3. The hardness of the processed workpiece: For steel parts with higher hardness, it is necessary to choose a machine tool with a better spindle;
4. The production volume of processed workpieces: It is a large batch of CNC milling machines that can be directly selected for specific purposes. If it is a small to medium batch or small parts processing, then a regular milling machine can be used;
5. Precision of machining workpieces: CNC milling machines can be selected for those with higher requirements;
6. The distance between the upper and lower turntables of the machine tool: to determine the height of the lower mold (forming mold);
7. Types of Workpieces: There are many types of workpieces on the market that can be selected according to customer requirements
8. The size of the workpiece: For smaller workpieces, you can choose a commonly used milling machine model; For workpieces with high requirements, a specific milling machine needs to be selected;
The characteristics of machining workpieces: For example, CNC milling machines choose appropriate system milling equipment based on the characteristics of the workpiece. For ordinary milling machines, consider the selection of rotary tables and other data references;
