Drilling means the machine tool that mainly uses drills on the workpiece.Usually the drill head rotation is the main movement, and the axial movement of the drill is moving to the feed movement.The diamond machine is simple and the processing accuracy is relatively low. It can be drilled and blinded, and the special tool can be replaced.So what are the operating procedures for drilling machine?What are the categories?
Basic classification
The drilling machine mainly uses drills to process the large drilling tool beds of the workpiece (such as drilling, expansion, rectus, attack wire, pores, etc.) on the workpiece.Machinery manufacturing and various repair factories are essential equipment.According to the use and structure, it is mainly divided into the following categories
The workbench and spindle box can be moved vertically on the column for small and medium -sized workpieces.
Referred to as the Taid Diamond.A small vertical drilling machine with a maximum diameter of the drilling hole is 12-15 mm. It is installed on the fitter platform, mostly manual drills, and small holes used to process small workpieces.
Rocker
The spindle box can move on the rocker arm, the rocker arm can turn around and lift, and the workpiece is fixed. It is suitable for large -scale and porous workpieces, which are widely used in mechanical manufacturing.
Deep -hole drilling machine
Drilling the depth with deep holes drilling is much larger than the pores with much diameter (such as the deep -hole of parts such as barrels, cannons, and machine tools, and other parts., Forestrown with coolant.
Vertical drill
The conveyor device (input coolant in the internal tool to the cutting site) and the periodic deprilleration device.
Central hole drilling machine
For the central hole of the two ends of the shaft parts.
Drilling machine
The workbench can move vertically and horizontally.
Horizontal drilling machine
The main axis layout, the main axis box can move vertically.Generally, the processing efficiency of Plaid Drilling machine can be processed at the same time.
The operating regulations of the drilling machine
1. Before work, it is necessary to comprehensively check whether the operation agencies of each ministry are normal. Wipe the rocker rails with a fine cotton yarn and pote the oil according to the lubricant number.
2. The rocker and the main shaft box can be operated after each department is locked.
3. There must be no obstacles within the scope of the rockers rotation.
4. Before opening the drill, the workben, workpiece, fixture, and blade of the drilling machine must be found and tight.
5. Correctly select the main axis speed and the amount of knife in advance.
6. Beyond the workbench to drill, the workpiece must be stable.
7. When the machine tool is running and automatically entering the knife, it is not allowed to change the speed of the tightening. If the transmission can only be completely stopped by the main axis.
8. The loading and unloading tools and measurement workpieces must be performed in the shutdown. Do not use the workpiece to drill directly by hand, and do not wear glove operations.
9. When there is an abnormal noise in the work, it is necessary to stop and check the failure immediately.
Diamond bed maintenance and maintenance
Extend the life of the diamond machine components and the wear cycle of parts to prevent various failures and improve the average failure working time and service life of the drilling machine.
Maintenance cycle
Daily maintenance is performed by drilling machines after each work or work.Regular maintenance is regularly carried out by professional maintenance personnel, once or once a year.
1. There should be operating procedures for drilling machines: regular maintenance, maintenance, failure to record the protection site of the protection of failure;
2. Power requirements;
3. When the drilling machine is not used, it should be stored in oil seal, covering the sealing film outside; 4. Training and equipped with corresponding operators, maintenance personnel and programming staff.
Drilling machine cleaning
1. Wipe the drilling table, bed, guide rail, screw and operating handle.Keep the bed and the surroundings clean, without oil pollution;
2. Clear the impurities of the guide surface of the rail surface and the screw drilling residue; 3. Disassemble and clean the oil felt; 4. Remove the rust of the drilling machine to protect the spraying surface.
CNC maintenance
1. Strictly abide by the operating procedures and daily maintenance systems;
2. Prevent dust from entering CNC device: Floating dust and metal powder are likely to cause the insulation resistance between the components to decrease, thereby failing or even damaging components;
3. Clean the heat dissipation and ventilation system of the CNC cabinet;
4. Power grid voltage that regularly monitor the CNC system: 85%to 110%of the voltage range of the power grid;
5. Regularly replace the battery for memory;
6. Maintenance when the CNC system is not used for a long time: often power the CNC system or run the temperature of the temperature machine to run the drilling machine;
7. Maintenance of spare circuit board.
Component maintenance
1. Maintenance of the screw and rail
① Regularly check and adjust the axial gap of the silk nut to ensure the accuracy and axial stiffness of the reverse transmission;
② Regularly check whether the connection between the screw support and the bed is loose and whether the support bearings are damaged.If you have the above problems, tighten the loosening site in time to replace the support bearing;
③ Use the roller screw with grease to clean the old oil on the screw every six months and replace the new oil.Use lubricant lubricating drip screws to refuel once a day before working;
④ Pay attention to avoid hard dust or dandruff into the screw cover and the protective cover during work. The protective device should be replaced in time as soon as it is damaged.
2. Maintenance of active axis
① Regularly adjust the tightness of the spindle box and the main axis driver belt;
② Check whether the spindle is axial or not;
③ Check and adjust the spindle clearance;
④ Prevent various impurities from entering the fuel tank.Replace lubricating oil once a year;
⑤ Keep cleaning the main axis and the knife handle.The displacement of the hydraulic cylinder and the piston must be adjusted in time.
Pneumatic maintenance
1. Clear the impurities and moisture of compressed air;
2. Check the fuel supply of the oil fog in the system;
3. Keep the system sealing;
4. Pay attention to adjusting work pressure;
5. Clean or replace pneumatic elements and filter elements.
Cutting fluid supply and maintenance
1. Regularly clean the pump, filter, cutting liquid box.
2. Check whether the cutting liquid pipe and nozzle are unblocked and there are leaks.
3. Replace the cutting fluid regularly.
4. Check the concentration and pH of the cutting fluid regularly.
