CNC Drilling And Tapping Machine to the process of automatically completing drilling and tapping using a CNC machine tool (CNC). CNC drilling and tapping are very suitable for precision machining, especially for processes that require surprise operations, rapid production, and continuous repetition. This equipment adopts a centralized drilling and tapping process design, which effectively improves the operating efficiency and speed of tapping operations and can process metal materials. CNC drilling and tapping rely on the CNC system to control the movement of the machine tool. The CNC system receives the machining program (usually G code) and converts it into motion instructions for the machine tool. The basic structure of the equipment is precision cast with high-quality HT300 cast iron, equipped with a BT30 model spindle with a speed of up to 20,000 rpm, a powerful 5.5 kW motor, and a 21T servo-driven disc tool magazine, which shortens the tool change time to 1.8 seconds.
Characteristics of CNC drilling and tapping
1. The machine tool adopts a mechatronics design to achieve intelligent control, with a simple and stylish appearance, mature structural design, and more intuitive and convenient user operation.
2. The machine tool can perform three-coordinate precise control through mechatronics design to ensure high-speed processing stroke and excellent processing accuracy.
3. The spindle adopts a variable frequency speed regulation system to achieve step-less speed change, replacing the traditional fixed speed setting, and improving the flexibility and efficiency of processing.
4. The machine tool is equipped with complete protective measures to ensure smooth movement, reduce noise, enhance waterproof, rust-proof, and chip-proof capabilities, and improve the durability and reliability of the machine tool.
5. The CNC drilling and tapping machine adopts an imported CNC system and supporting drivers and motors, which can achieve high-precision three-axis linkage.
6. This machine is suitable for complex, multi-process, high-precision processing tasks that require multiple types of ordinary machine tools and a variety of tools and tooling, or batch parts that can only be processed after multiple clamping and adjustments.

6. High positioning accuracy: The positioning accuracy reaches ±0.005mm, which ensures the accuracy of processing and is suitable for processing tasks with high precision requirements.
Working Principle of CNC Drilling and Tapping
CNC drilling and tapping is to form circular holes and threads on materials or workpieces through computer-controlled machine tools. The goal of CNC drilling is to form circular holes in materials or workpieces while tapping is to form threads in the drilled holes. In CNC drilling, twist drills are usually used, while the tool of choice for tapping is a tap drill. In rigid tapping, the feed amount of the drilling axis corresponding to one rotation of the spindle must be equal to the pitch of the tapping to maintain synchronization between the rotation of the spindle and the feed of the feed axis.
