Drilling and milling machines ultimately cannot do without daily maintenance

Drilling and milling machine is a machine tool equipment that integrates drilling, milling, boring, and grinding, and is used for processing small and medium-sized parts. Suitable for processing various small and medium-sized parts, especially for cutting non-ferrous metal materials, plastics, and nylon. It has the advantages of simple structure and flexible operation, and is widely used in single or batch mechanical manufacturing, instrument industry, building decoration, and repair departments.

Drilling and milling machine is a small and medium-sized general-purpose metal cutting machine tool that can perform both horizontal and vertical milling. It is suitable for drilling, expanding, reaming, boring, and hole processing. If circular disc milling machines, angle milling cutters, forming milling cutters, and end face milling cutters are used, they can mill flat, inclined, vertical, and groove surfaces. After installing the accessory end milling head, it can be used for multi-directional milling work. After installing the accessory indexing head, it can be used for milling straight teeth, bevel gears, and spiral teeth with a mold size of m=3 millimeters or less. Due to its wide application, this machine tool is suitable for general repair and tool workshops, as well as single piece or small batch production workshops.

Daily maintenance of drilling and milling machines:

1. Clean the surface and dead corners of the machine tool, remove and wash each cover, and ensure that the inside and outside are clean, free of rust, yellow robe, and the paint is visible in its natural color. Clean the guide rail surface and remove burrs from the workbench. Check and complete the screws, handball, and hand board, and check the flexibility and reliability of each handle.

2. Main spindle feed box maintenance: Check the oil quality, maintain it in good condition, and ensure that the oil level meets the requirements. Remove burrs from the spindle taper hole. Clean the hydraulic transmission system, oil filter, and adjust the oil pressure.

3. Inspection of the rocker arm and lifting and clamping mechanism of the drilling and milling machine: Check and adjust the lifting and clamping mechanisms to ensure sensitivity and reliability.

4. Inspection of lubrication system for drilling and milling machine: Clean the oil felt and ensure that the oil cup is complete, the oil circuit is unobstructed, and the oil window is bright.

5. Inspection of cooling system for drilling and milling machine: Clean the cooling pump, filter, and cooling liquid tank. Check the coolant pipeline and ensure that there is no water leakage.

6. Inspection of the electrical system of the drilling and milling machine: Clean the dust inside and outside the motor and electrical box. Turn off the power, open the electrical door cover, and check if the electrical connectors and components are loose or aging. Check if the limit switch is working properly. Does the power outage when opening the door work. Check if the hydraulic system is functioning properly, if there is any oil leakage, and if all electrical control switches are functioning properly.
