Mainly use a knife to cut the prefabricated holes in the workpiece.Generally, the sword rotation is the main movement, and the movement of the knife or workpiece is moved.It is mainly used for processing high -precision holes or one -time positioning to complete multiple holes. In addition, it can also be engaged in processing other processing planes related to pore essence.So what are the operating procedures of the bed?How to maintain the bed?
The operating rules of the bed bed
1. Comply with the general safety operation procedures for milling workers.Wear labor protection supplies in accordance with regulations.
2. Check whether the connection between the operating handle, switch, knob, fixture mechanism, and hydraulic piston is in the correct position, whether the operation is flexible, and whether the safety device is complete and reliable.
3. Check whether there are obstacles within the effective operation range of each axis of the machine tool.
4. It is strictly forbidden to use machine tools.Select the rational cutting speed and feed volume according to workpiece materials.
5. When loading and unloading heavier workpieces, a reasonable patch and hanging method must be selected according to the weight and shape of the workpiece.
6. The spindle rotates. When moving, it is strictly forbidden to touch the spindle with your hands and the tools installed on the main axis.
7. When replacing the tool, you must stop it first. After confirmation, you can change it. You should pay attention to the damage of the blade when replacing.
8. Forbidden the rail surface and paint surface of the stepping equipment or place items on it.It is strictly forbidden to knock on the workbench or direct workpiece.
9. After the new workpiece enters the processing program, it must check the correctness of the program to simulate whether the running program is correct. It is not allowed to perform automatic circulation operations without testing to prevent the machine tool from failing.
10. When using a flat rotor radial cutting frame separately, you should first return the rod to zero, and then use the M43 to replace it to the flat tray method under the MDA mode.Tight -loading has been released.
11. When a spin station (axis) is required at work, it should be ensured that it will not encounter other components of the machine tool when rotating, nor can it encounter other objects around the machine tool.
12. When running the machine, the rotating silk shaft, light rod, main shaft, and flat spinning disk are prohibited. The operator shall not stay on the mobile parts of the machine tool.
13. When the machine is running, the operator is not allowed to leave the job or take care of it without authorization.
14. Abnormal phenomena and noise occur during the operation of the machine tool. It should be stopped immediately to find out the reason and deal with it in time.
15. When the main axis box of the machine tool, the workbench is in or close to the limits of the motion, and the operator shall not enter the following areas:
(1) Between the bottom surface of the spindle box and the bed;
(2) Between the axis and work;
(3) When the shaft is extended, it is between the bed or the work table;
(4) between the workbench and the spindle box;
(5) When the axis is rotated, the rear tail tube is between the wall and the fuel tank;
(6) Between the workbench and the front column; (7) Other areas that may cause squeezing;
16. When the machine tool is shut down, the workbench must be returned to the middle position, the rod is returned, and then the operating system is exited, and the power is cut off.
Maintenance of bed beds
The maintenance work of maintenance work is mainly to pay attention to cleaning, lubricating and reasonable operations.Daily maintenance work is divided into the following three stages:
1) Before the start of work.Check whether the components and mechanisms of the machine tool are intact, and whether the position of each handle is normal; clean the machine tools, observe the lubrication devices, and directly pour the machine tool guide surface. The low -speed air runs for a certain period of time.
2) During the work process.It is mainly to operate correctly. The machine tool is not allowed to work in overload. Rough processing cannot be used for precision machine tools.During the work process, it was found that there was any abnormal phenomenon in the machine tool, and it should be stopped immediately.
3) After the work is over.Wash the machine tools in each part of the machine, move each mobile component of the machine to the prescribed position, and turn off the power.
First -level maintenance
After the bed generally stipulates that after 800h, the operator is mainly based on a first -level maintenance, and the maintenance work must be carried out after cutting off the power supply.Let ’s take the bedding bed in this type as an example to illustrate the content and requirements of the first -level maintenance of the bed.
1) External maintenance.Mainly remove the surface dirt and rust of the machine tool, and keep the transmission cleaning.The surface and cover of the machine tool should be rustless and non -macular; scrubbing the exposed screws, light bars and racks; supplement each handle, screw, nut and other parts to keep the appearance of the machine tool clean.
2) Sub -box and feed gearbox maintenance.Open the dust cover of the main axis box and check the V -belt and the main shaft box clamp the lever.Clean each filter and oil tank; check the tightness of the balanced hammer wire rope; scrubbing the stirring plate sliding and adjusting the inlaid.
3) Workbenters and rail maintenance.Over the scrubbing workbench, check the adjustment of the iron and inlaid gaps; check whether the guide rail is pulled, light the burrs and wipe the guide rail.
4) Standing pillars for maintenance.Wipe the bearing seat and guide surface to check and adjust the inlaid gap.
5) Lubricating system maintenance.Clean the custard and oil grooves to keep the oil holes and oil circuits unblocked.Clean the cooling pump, filter and cooling box.Clean the filter to ensure that the oil cups are complete and keep the oil -standard oil windows bright.
6) Maintenance of electrical parts.Clean electric box and electric motor.Check the location of the electrical device to ensure that the electrical device is fixed, safe and neat.The operating system, finally cut off the power.
Precautions
Metal cutting machines have implemented the quality license system for export products, and products that have not obtained the quality license of export products are not allowed to be exported.Except for the clear requirements during order, the equipment parameters, British -made, power supply voltage, weeks, and random attachments, and machine tool colors must be clearly stipulated.
