Characteristics of CNC deep hole drilling machines

CNC Deep Hole Drilling is a machine tool used for deep hole processing. It has the characteristics of fast, accurate and stable deep hole processing. Widely used in mold manufacturing, machinery manufacturing, automobile manufacturing and other industries.

CNC deep hole drilling machine is a machine for processing cylindrical deep hole parts. It can drill buried holes, step holes and buried holes, and can also carry out smooth extrusion processing. For short workpieces (1-4m), the double cone disk tightening method is used, and the oil is supplied by the oil dispenser. Use push boring as the boring method. As for the chip removal method, forward chip removal is used, which is suitable for mass production and can also be used for small batch production of parts.

The influence of the CNC machine tool used in the machining process on the choice of tool type (drill, Turning tool or Milling cutter) for the CNC deep hole drilling machine. High-productivity tools such as high-speed cutting tools and large-feed turning tools can ensure the rigidity of the workpiece system and the rigidity of the CNC deep hole drilling machine tool system.

There are two types of CNC deep hole drilling machine tools: general type, special type and ordinary lathe. In order to facilitate cooling and chip removal, the deep hole drill bits are all arranged horizontally. The main parameter of the deep hole drill bit is the large drilling depth. Automatic tool feeding requires selecting the feed speed and adjusting the travel limit block. Manual feed is generally carried out according to the principle of gradual pressure increase and pressure reduction to avoid accidents caused by excessive force.

CNC deep hole drilling has a wide range of applications, mainly in the following aspects:

Mold manufacturing: Molds are the core of precision parts, and the requirements for hole processing in molds are often very strict. The CNC deep hole drill's high precision, automatic compensation of upper and lower knives, and automatic programming can meet the needs of various mold processing, including plastic molds, die-casting molds, stamping molds, etc. Using CNC deep hole drilling for efficient and high-quality mold processing can greatly improve the efficiency and quality of mold manufacturing and meet the requirements for mold processing accuracy in different industries.

Machinery manufacturing: CNC deep hole drilling can be used to process deep holes in mechanical parts, such as engine blocks, oil supply system parts, transmission system parts, etc. The deep hole processing accuracy and efficiency of these parts have an important impact on the performance and service life of the entire machinery.

Automobile manufacturing: Automobile manufacturing requires a large amount of deep hole processing, such as steering shafts, steering mechanism housings, etc. CNC deep hole drilling can complete these processing tasks efficiently and with high precision, improving the quality and performance of automobiles.

Aerospace: Parts such as thrusters and landing gears in the aerospace field also require deep hole processing. CNC deep hole drilling can meet these high-precision and high-efficiency processing needs.

There are significant differences between CNC drilling machines and CNC lathes in many aspects:

Working principle: CNC drilling machines mainly use drill bits as the main processing tools to process workpieces by drilling or reaming. CNC lathes use cutting tools as the main processing tools to process workpieces through cutting, milling and other methods.

Processing objects: CNC drilling machines are mainly used for drilling, reaming, reaming and other operations, and are suitable for processing workpieces with smaller hole diameters and larger depths. CNC lathes are suitable for processing circular or conical workpieces with larger diameters, such as shafts, hubs, flanges, etc.

Processing method: CNC drilling machine feeds the drill bit along the axis of the workpiece to be processed and rotates it to achieve operations such as drilling or reaming. The CNC lathe clamps the workpiece to be processed, places the tool on the workpiece, and realizes operations such as cutting and milling through the rotation of the workpiece axis and the movement of the tool on the surface of the workpiece.

Mechanical structure: The mechanical structure of CNC machine tools mainly consists of basic parts, main transmission system, feed transmission system, rotary table and other mechanical functional accessories. Since CNC machine tools use servo motors and apply digital technology to realize direct control of the working sequence and motion displacement of the machine tool's execution components, the transmission structure of the traditional machine tool has been canceled or partially eliminated, so the mechanical structure has been greatly simplified.

The advantages of CNC deep hole drilling are mainly reflected in the following aspects:

High precision: CNC deep hole drilling can be controlled by computer programs to achieve high-precision deep hole processing. Its drilling depth, diameter and other parameters can be accurate to the millimeter level, improving processing accuracy and product quality.

High efficiency: CNC deep hole drilling adopts advanced drilling technology and automatic control technology, which can complete a variety of complex hole processing tasks in a short time, greatly improving processing efficiency. At the same time, through the control of the CNC system, the effect of processing multiple holes at the same time can be achieved, improving processing efficiency and production capacity.

Integrated processing: In addition to deep drilling, CNC deep hole drilling can also perform reaming, tapping, Grinding and other functions to meet the needs of various workpiece processing and form an integrated processing solution. Improved production efficiency and product quality.

High degree of automation: CNC deep hole drilling has a high degree of automation, which reduces the impact of human factors on the processing process and improves the stability and reliability of the processing process.

Reducing costs: Although the equipment cost of CNC deep hole drilling is relatively high, its long-term production efficiency and reduced worker costs will also greatly reduce processing costs and have high investment value.
