The glass drilling machine is an industrial machinery and equipment. You must be careful when using it. You must master the methods of using the glass drilling machine and the precautions for the use of the glass drilling machine. First of all, before the work starts, the method of using the glass drilling machine is to inject lubricating oil into each oil filling part first, and clean the core material in the receiving drawer in time. Secondly, the precautions for the use of the glass drilling machine include: do not touch the moving parts when the machine starts, live parts, and emergency situations, immediately press the "emergency stop" button or pull down the air switch, etc. Let's continue to look at the specifics!1. How to use the glass drilling machineThe glass drilling machine is a machine specially used for drilling glass. It is mainly divided into: base, operating table, drill bit, motor, etc. The diameter of the drilling hole is large, and the overhang space of the machine base is large, which can drill holes in various sizes of glass. Work, the height of the worktable is low, the operation is convenient, and the lower drill bit adopts air pressure speed regulation, and the speed is stable. It is an ideal drilling machine for glass processing enterprises. So do you know how to use a glass drilling machine?1. When drilling glass, the lower drill bit is easy to crush the glass, so when drilling thin glass, the pressure must be adjusted very low, which can be changed in the range of 0.18 ~ 03MPa, and when drilling thick glass, the pressure can rise to about 0.46MPa .2. Before the start of each shift, lubricating oil should be injected into each oiling part first, and the tightness of the belt should be checked, whether the upper and lower drill shafts are running abnormally, and whether the drill bit is worn, and the work can be started after everything is normal.3. The core material in the receiving drawer should be cleaned in time, otherwise too much material accumulation will jam the receiving device. Especially when drilling large holes with a diameter greater than 100mmj, it should be cleaned every few holes drilled.4. When cleaning the core material, the receiver should be in the receiving position, so that the receiving drawer can be pulled out smoothly. Therefore, when cleaning the core material, the drill should be started to rotate. At this time, the receiver will be in the receiving position, which can be easily cleaned. material core.2. What are the precautions for the use of glass drilling machinesAfter understanding how to use the glass drilling machine, the precautions during use must also be clear:1. Pay attention to safety when debugging and using the glass drilling machine. Do not touch the moving parts and live parts when the machine is started.2. Do not put tools and other objects on the conveying rail and cover.3. In case of emergency, immediately press the "emergency stop" button or pull down the air switch.4. Pay attention to the grinding situation of the glass drilling machine at any time: the loss of the grinding wheel should be compensated by the feed in time.5. Keep the cooling water in the water tank sufficient and the water quality clean at any time, so as not to burn the grinding wheel and glass, and clean up the grinding impurities in the water inlet and outlet pipes in time to keep the waterway unobstructed.6. Before working, check whether the travel switches of all glass drilling machines work normally and whether the control direction is correct. If it is not correct or the control direction is wrong, it should be stopped immediately for inspection, otherwise the glass drilling will be fatally damaged.7. Do a good job of personal protection, wear goggles and cut-resistant gloves. Shoes and clothing with bare skin are prohibited to prevent cuts.
Glass cutting machine, as the name implies, is a machine used to cut glass, mainly used for glass processing and blanking. As a large-scale machine, glass cutting machine should pay attention to the correct operation method. When operating the glass cutting machine, you should take protective measures, turn on the power, and after starting the program, place the glass to be cut on the cutting table, fix the glass after positioning, and wait for it to automatically cut; remove the glass after cutting , clean the countertop and then proceed to the next piece of glass cutting operation. Let's take a look at the operation method and precautions of the glass cutting machine.1. What is a glass cutting machine?Glass cutting machine, as the name implies, is a mechanical equipment used to cut glass. It is a processing machine specially used for glass processing and blanking. composed of other parts.Second, the operation method of glass cutting machineThe glass cutting machine is a kind of large-scale machinery. When using and operating, pay attention to the correct operation methods and procedures. The method and steps of the correct operation of the glass cutting machine are as follows:1. Take safety protection measures, wear gloves, protective glasses, and special iron shoes.2. Turn on the power switch, start the ncstudio program, first all return to the mechanical origin, then return to the fixed point, then load the programs that need to be applied, and confirm these programs.3. Place the glass to be cut on the cutting table of the glass cutting machine.4. Press the blow button on the cutting machine, so that the glass can float on the cutting table and move freely for easy positioning.5. Position the glass on the cutting table, press the stop button to end the blowing function, then step on the suction switch with your foot, and use the suction function to firmly fix the glass on the appropriate position of the cutting table, which is convenient for cut.6. After the cutting is completed, press the stop switch to stop the suction function, and then turn on the blow switch.7. Turn on the blowing switch of the parting table, clean up the debris and dust on the table, and then move the whole cut glass to the parting table in parallel. Be careful during the movement.8. For the glass on the parting table, first clean the surrounding materials and place them in the designated corresponding positions, and then divide the whole glass into small pieces according to the cut marks.9. After distinguishing each small piece of glass, insert the frame vertically in a row. This process must not be omitted, and the vertical angle of the glass must be guaranteed.10. After a piece of glass is cut, use an air gun to clean the cutting table and the parting table of the cutting machine, and then you can place the next piece of glass for new cutting work.3. What matters should be paid attention to when operating the glass cutting machine1. When the glass cutting machine is in use, it is not allowed to plug and unplug the parallel cable connected to the computer, and do not plug and unplug any hardware equipment such as the control card. The computer or glass cutting machine shell should be grounded to ensure safety and prevent interference. The machine does not work Please turn off the power in time, and unplug the power plug when not in use for a long time.2. Before operation, turn on the power to return to zero, and then manually try various functions, including injecting cutting oil, whether the air pressure is normal, and whether the cutter head is worn or not.3. When loading a graph, make sure that the loaded graph is within the cutting range.4. Check the glass to be cut before cutting, and it is required that the appearance should not have white spots and scratches.5. When cutting, make sure that there is no one beside the y-axis.6. In principle, the glass cutting machine should not perform other operations during operation, and other non-emergency stop operations should be performed after the cutting is completed.7. After using the glass cutting machine to cut a piece of glass, clean the table in time to prevent glass chips from scratching the table.
The laser cutting machine is to focus the laser emitted from the laser into a high power density laser beam through the optical path system. The laser beam is irradiated on the surface of the workpiece, making the workpiece reach the melting point or boiling point, while the high-pressure gas coaxial with the beam blows the molten or vaporized metal away. With the movement of the relative position of the beam and the workpiece, the material is finally formed into a slit, so as to achieve the purpose of cutting. Laser cutting process replaces the traditional mechanical knife with invisible beam, which has the characteristics of high precision, fast cutting, not limited to cutting pattern, automatic typesetting to save materials, smooth incision, and low processing cost. Learn more about it in the next installment.First, the principle of laser cutting machineA laser is a kind of light that, like other natural light, is produced by the transition of atoms (molecules or ions, etc.). But it is different from ordinary light in that laser only relies on spontaneous emission for a very short period of time at first, and the subsequent process is completely determined by stimulated emission, so laser has a very pure color, almost no divergent directionality, and extremely high luminous intensity. and high coherence.Laser cutting is achieved by applying high power density energy generated by laser focusing. Under the control of the computer, the laser is discharged through pulses, thereby outputting a controlled repetitive high-frequency pulsed laser to form a beam with a certain frequency and a certain pulse width. The pulsed laser beam is transmitted and reflected through the optical path and focused on the On the surface of the processed object, tiny, high-energy-density light spots are formed, and the focal spots are located near the surface to be processed, melting or vaporizing the processed material at an instant high temperature. Each high-energy laser pulse instantly sputters a small hole on the surface of the object. Under the control of the computer, the laser processing head and the material to be processed perform continuous relative motion and dot according to the pre-drawn pattern, so that the object will be processed into desired shape.The process parameters (cutting speed, laser power, gas pressure, etc.) and movement trajectory during slitting are controlled by the numerical control system, and the slag at the slit is blown off by a certain pressure of auxiliary gas.Second, the main process of laser cutting machine1. Vaporization cuttingDuring the laser vaporization cutting process, the surface temperature of the material rises to the boiling point temperature so fast that it can avoid melting caused by heat conduction, so part of the material vaporizes into steam and disappears, and part of the material is ejected from the bottom of the slit by the auxiliary gas Flow blows away. Very high laser powers are required in this case.To prevent material vapor from condensing on the kerf wall, the thickness of the material must not greatly exceed the diameter of the laser beam. This process is therefore only suitable for applications where the exclusion of molten material must be avoided. This machining is really only used in very small areas of use for iron-based alloys.This process cannot be used, such as wood and certain ceramics, which are not in a molten state and therefore less likely to recondense the material's vapors. In addition, these materials typically achieve thicker cuts. In laser gasification cutting, optimal beam focusing depends on material thickness and beam quality. The laser power and the heat of vaporization have only a certain influence on the optimal focus position. In the case of a certain thickness of the plate, the maximum cutting speed is inversely proportional to the gasification temperature of the material. The required laser power density is greater than 108W/cm2 and depends on the material, depth of cut and beam focus position. In the case of a certain thickness of the sheet, assuming sufficient laser power, the maximum cutting speed is limited by the velocity of the gas jet.2. Melting and cuttingIn laser melting cutting, the workpiece is partially melted and then the melted material is ejected by means of an air flow. Because the transfer of the material occurs only in its liquid state, the process is called laser melting cutting.The laser beam coupled with a high-purity inert cutting gas pushes the molten material out of the kerf without the gas itself cutting. Laser fusion cutting can achieve higher cutting speeds than gaseous cutting. The energy required for gasification is usually higher than the energy required to melt the material. In laser melting cutting, the laser beam is only partially absorbed. The maximum cutting speed increases with increasing laser power and decreases almost inversely with increasing sheet thickness and material melting temperature. In the case of a certain laser power, the limiting factor is the gas pressure at the kerf and the thermal conductivity of the material. Laser fusion cutting can produce oxide-free cuts for iron and titanium. The laser power density that produces melting but not gasification is between 104W/cm2 and 105 W/cm2 for steel materials.3. Oxidation melting cuttingFusion cutting generally uses inert gas. If oxygen or other active gas is used instead, the material will be ignited under the irradiation of the laser beam, and a violent chemical reaction with oxygen will generate another heat source to further heat the material, which is called oxidative melting cutting. .Due to this effect, for the same thickness of structural steel, higher cutting rates can be obtained with this method than fusion cutting. On the other hand, this method may have a poorer cut quality than fusion cutting. In practice it produces wider kerfs, noticeable roughness, increased heat affected zone and poorer edge quality. Laser flame cutting is not good for precision models and sharp corners (risk of burning the sharp corners). Thermal effects can be limited using a pulsed-mode laser, where the power of the laser determines the cutting speed. At a given laser power, the limiting factors are the supply of oxygen and the thermal conductivity of the material.4. Control fracture cuttingFor brittle materials that are easily damaged by heat, high-speed and controllable cutting by laser beam heating is called controlled fracture cutting. The main content of this cutting process is that the laser beam heats a small area of brittle material, causing large thermal gradients and severe mechanical deformation in this area, resulting in the formation of cracks in the material. The laser beam can direct cracks in any desired direction as long as a uniform heating gradient is maintained.
