The double head boring machine is a high precision machine tool used to process large or complex holes. It is widely used in aviation, automobile, metallurgy, machinery manufacturing and other industries. It generally has two independent processing systems, which can process two holes of the workpiece at the same time, improving production efficiency and processing precision. This article will introduce the operational skills of a double head boring machine and answer some common questions to help operators improve work efficiency and reduce breakdowns.
1. Basic Operational Skills
1. Install the workpiece correctly
When using it, first ensure the installation accuracy of the part. The workpiece must be placed accurately on the workbench or stand, ensuring that it is parallel to the centerline of the boring machine spindle. You can ensure that there is no deviation in the workpiece by using special measuring tools such as dial gauges, center feelers, etc. Incorrect installation can lead to machining errors or even damage to tools and machine tools.
2. Select the appropriate tools and cutting parameters
It is often used to process workpieces with larger hole diameters, therefore the choice of tools and cutting parameters (such as rotation speed, feed, etc.) is very important. Tool selection should be determined based on the workpiece material, hole size and processing requirements. Cutting parameter adjustment should be combined with the tool material and workpiece hardness to avoid excessively high or low rotational speed and feed rate to avoid wear of the tool or substandard processing quality.
3. Reasonably adjust the functions of the machine tool
During the processing process, the operator should reasonably adjust various functions of the double head boring machine according to different processing needs. For example, adjust the boring head stroke, cutting depth, feed rate, etc. Reasonable adjustments can ensure smooth treatment and improve treatment efficiency. For complex processing tasks, it is also possible to achieve the best results through multiple adjustments and step-by-step processing.
4. Check the condition of each component of the machine tool
Before starting processing, the operator should check various components of the double head boring machine, especially whether the movement of the spindle, tool holder and worktable is stable and whether the lubrication system is stable. The oil works properly to avoid malfunctions during treatment. . At the same time, regular cleaning of dust and chips on the machine tool will help extend its service life.
5. Operational safety awareness
During operation, the operator must maintain a high degree of safety awareness at all times. Wear appropriate protective equipment such as safety glasses, earplugs, work clothing, etc. to ensure your personal safety. When changing or adjusting tools, make sure the machine tool is stopped and all locking devices are tightened in place before use.
2.FAQs
1. Vibration or noise increases during treatment.
Answer: Increased vibration and noise are usually caused by unstable tools or parts, improper cutting parameters, loose or damaged machine tools, etc. First, check the tool for wear or instability and replace or adjust it if necessary. Second, check if the part is firmly installed and make sure the device and part are in the correct position. Finally, check if the various parts of the machine tool are loose, especially the connection between the spindle and the tool holder. Adjusting cutting parameters, such as reducing cutting depth or feed rate, can help reduce vibration.
2. What should I do if the position of the processed hole is offset?
Answer: Hole position deviation may be caused by incorrect workpiece clamping or insufficient alignment accuracy of the machine tool. First, check the installation accuracy of the part and use the appropriate measuring tools to ensure that the part is aligned with the spindle. Second, check the calibration of the machine tool to ensure that the spindle and power system of the machine tool are in good condition. If the problem persists, machine accuracy calibration or repair may be necessary.
3. The machined surface is rough, how to improve it?
Answer: There can be many reasons why the machined surface is rough. First, check if the tool is dull or damaged. Dull tools can cause uneven cutting and affect surface quality. Second, check whether the cutting parameters are reasonable. Excessive cutting speed and feed can cause surface roughness. The rotation speed and feed speed can be adjusted appropriately to ensure a smooth cutting process. Additionally, the choice and use of lubricating oil is also crucial. Proper lubrication can reduce friction and improve processing quality.
4. The tool wears out too quickly, how to extend the life of the tool?
Answer: Excessive tool wear is usually caused by improper cutting conditions, poor selection of tool materials, or excessive workpiece hardness. First, check if the cutting parameters are appropriate. Excessive rotational speed and feed will increase tool wear. Second, choose a tool suitable for the material of the workpiece. Carbide tools are generally suitable for processing hard materials. Finally, maintain an adequate supply of cutting fluid. The function of cutting fluid is cooling and lubrication, which helps reduce tool wear.
5. The cutting force is unstable during processing. How to solve this problem?
Answer: Unstable cutting forces can be caused by unstable tools, weak workpiece mounting, or improper cutting conditions. First, make sure the cutter is securely installed and check if it is badly worn. If the feed rate is too high or the cutting depth is too large, these parameters can be adjusted appropriately to reduce the cutting force. Also check the tightness of the part to ensure its stability.
