Vertical drilling machine
Vertical drilling machines are a common metal processing equipment widely used in industries such as mechanical manufacturing, automotive manufacturing, aerospace, etc. It is mainly used for drilling, reaming, and expanding processes. The working principle of a vertical drilling machine is to drive the spindle to rotate through an electric motor, which drives the drill bit to drill holes. The drill bit uses cutting force to cut metal materials, forming holes.
The role of vertical drilling machines in industrial processing mainly includes the following aspects:
Drilling processing: Vertical drilling machines are important equipment for drilling processing. It can drill various materials, such as metal, plastic, wood, etc., for manufacturing various products, such as mechanical components, automotive components, electronic products, etc. Drilling processing can meet the requirements of different workpiece apertures, depths, and accuracy.
Reaming processing: Vertical drilling machines can also perform reaming processing. Reaming is a process used to process threaded holes. By drilling and then using a reamer, precise internal threaded holes can be obtained, which are used for installing threaded connections such as bolts, nuts, etc.
Expanding processing: Vertical drilling machines can also perform expanding processing. Expanding a hole is a process of expanding the original aperture to the required size by drilling and using special tools for processing. Expanding holes can be used to adjust the aperture size and adapt to different assembly requirements.
Positioning processing: The workbench of a vertical drilling machine can move and fix in the up and down, front and back, left and right directions. By adjusting the position and angle of the workpiece, positioning processing can be achieved. Positioning machining can ensure the stability and accuracy of the workpiece during the machining process, and improve the machining quality.
Multi station processing: Vertical drilling machines can be equipped with multiple workstations, and through the switching of workstations, multi station processing can be achieved. Multi station processing can perform multiple processes on the same equipment, improving production efficiency and process accuracy.
The workflow of a vertical drilling machine:
Preparation work: Firstly, it is necessary to fix the workpiece to be processed on the workbench, usually using fixtures or fixtures to hold the workpiece to ensure its stability and accuracy.
Choose a suitable drill bit: Based on the material and processing requirements of the workpiece, choose a suitable drill bit. The diameter and material of the drill bit should match the workpiece to ensure processing efficiency and workpiece quality.
Adjusting the position of the drill bit: Adjust the position and feed depth of the drill bit according to processing needs. Usually, manual or automatic control systems are used to achieve this.
Start the drilling machine: Turn on the power and start the drilling machine. The motor drives the spindle to rotate, and the drill bit begins to rotate.
Feed drill bit: Control the feed device to slowly feed the drill bit above the workpiece. The feed speed should be moderate to ensure cutting efficiency and workpiece quality.
Start drilling: When the drill bit contacts the surface of the workpiece, appropriate cutting force is applied to gradually penetrate the workpiece and form a hole.
Cooling lubrication: During the drilling process, it is necessary to use cooling lubricants to cool and lubricate the drill bit and workpiece, in order to reduce friction and heat, improve cutting efficiency and workpiece quality.
