First, the use of drilling and milling machine
Drilling and milling machine is a machine tool that integrates drilling, milling, boring and grinding. It is suitable for processing various small and medium-sized parts, especially It is non-ferrous metal material; plastic; nylon cutting, has the advantages of simple structure and flexible operation, and is widely used in single-piece or batch machinery manufacturing; instrument industry; building decoration and repair departments.
The drilling and milling machine is a small and medium-sized general-purpose metal cutting machine, which can be used for horizontal milling and vertical milling. It is suitable for drilling, expanding, reaming, boring and hole processing; such as with wafer milling machines, angle milling cutters, forming milling cutters and end milling cutters, it can mill planes, inclined surfaces, vertical surfaces and grooves. After installing the attachment end milling head, it can be used as multi-directional milling work. After the attachment indexing head is installed, it can be used for milling of spur gears, bevel gears and helical gears with a touch of m=3 mm or less. Because this machine tool is widely used, it is suitable for general repair and tool workshops; it is suitable for single-piece or small batch production workshops.
The structure of this machine tool is composed of nine main components, including bed, base, triangle, worktable and sliding seat, sliding arm swivel seat, milling head, cooling and lubrication, and electrical system. The bed is installed on the base, and the main motor is installed in the lower abdomen of the bed. It is transmitted to the I-axis through a pair of V-belt pulleys into the bed gear box, and is transmitted to the main shaft through six pairs of gears. The front end of the main shaft is a Morse No. 4 taper hole. The end mill shank can be installed, and the tool holder can also be installed. The other end of the long tool holder is supported in the bearing hole of the hanger, and the tool holder bracket is installed on the dovetail guide rail of the sliding arm.
2. Operation steps of universal drilling and milling machine
1. Preparation before operation
Power supply Whether the switch is turned on; whether the work object is clamped; whether the lubricating oil on the guide rail surface of the workbench meets the requirements, and check whether the oil pump of the gear box is automatically filled with oil.
2. Operation steps
Press the “green” start button to make the spindle run; press the “red” button to stop the spindle.
3. Abnormal handling
Press the “red” button or cut off the power supply if an abnormal situation occurs during operation; if it is found that the automatic cutting tool fails, stop , please check with the relevant technical personnel.
4. Precautions
Clamping tools, cutting tools and workpieces must be firm and reliable, and must not be loose.
When tightening, adjusting, shifting, measuring workpieces, upper and lower workpieces, and tools, it must be stopped; during cutting, the head and hands should not be close to the milling surface: when removing and unloading the workpiece, the tool must be removed. When the knife is being moved, it is not allowed to stop, the knife can not be too violent, and it is not allowed to change the feeding speed suddenly; Only brushes are permitted.
3. Daily maintenance of drilling and milling machine
1. Clean the exterior and dead corners of the machine, disassemble and wash each cover, and require clean inside and outside, no rust, no yellow robes , The paint sees the natural color and the iron sees the light. Clean the rail surface and remove the burr on the work surface. Check and fill up screws, handballs, and hand boards, and check the flexibility and reliability of each handle.
2. Maintenance of the spindle feed box: check the oil quality, keep it in good condition, and the oil quantity meets the requirements. Remove burrs from spindle taper holes. Clean the hydraulic transmission system, oil filter screen, and adjust the oil pressure.
3. Inspection of rocker arm and lifting and clamping mechanism of drilling and milling machine: Check and adjust the lifting mechanism and clamping mechanism to be sensitive and reliable.
4. Inspection of the lubrication system of the drilling and milling machine: cleaning the linoleum requires complete oil cups, smooth oil passages, and bright oil windows.
5. Check the cooling system of the drilling and milling machine: clean the cooling pump, filter and coolant tank. Check the coolant line and make sure 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 door cover of the electrical appliance, and check whether the electrical connectors and electrical components are loose or aged. Check that the limit switches are working properly. Whether opening the door and power off will work. Check whether the hydraulic system is normal and whether there is oil leakage.
