Guide to Maintenance of Glass Double Edgers: Ensuring Efficient and Precise Operation

 

Glass double edgers play a crucial role in the glass processing industry. They are capable of simultaneously performing fine processing such as grinding and polishing on two edges of glass, effectively improving the edge quality and production efficiency of glass products. However, recently, during the process of returning visits to customers' factories and providing after-sales services by Locke engineers and export business personnel, it was found that most of the machine's malfunction problems were often caused by the lack of reasonable maintenance. Therefore, in order to maintain the excellent performance of the glass double edger for a long time and stably output high-quality processing results, scientific and reasonable maintenance work is essential.

 

 

 

I. Daily Cleaning: Keeping the Machine Body and Working Area Clean

During the daily operation of the glass double edger, a large amount of glass dust will be generated. This dust will not only adhere to the surface of the machine body but also float to every corner of the working area. If not cleaned in time, the dust may enter key parts such as mechanical transmission components and electrical control systems, accelerating the wear of components, affecting the normal operation of the equipment, and even possibly causing electrical faults.

 

Therefore, after the work is completed every day, the operator must use a clean compressed air spray gun to comprehensively blow off the glass dust on the machine body, workbench, transmission track, and grinding wheel protective cover of the glass double edger. At the same time, the accumulated dust on the ground of the working area should also be swept clean in time, and the floor should be mopped regularly with a wet mop to reduce dust flying. In addition, the operation panel should be wiped with a soft wet cloth to prevent the accumulation of dust from affecting the operation sensitivity and display clarity.

 

II. Grinding Wheel Maintenance: Ensuring Grinding Performance and Precision

The grinding wheel is one of the core components of the glass double edger, and its condition directly affects the grinding effect and processing precision of the glass. During the processing, the grinding wheel will gradually wear out. When the wear reaches a certain degree, if it continues to be used, it will not only cause quality problems such as uneven grinding and scratches on the glass edge but also may cause the grinding wheel to vibrate when running at high speed, causing greater damage to the equipment.

The operator should regularly check the wear condition of the grinding wheel. Generally, it can be preliminarily judged by observing the processing quality of the glass edge. If burrs, increased roughness, or obvious uneven grinding marks are found on the glass edge, the grinding wheel needs to be checked in time. When the grinding wheel is worn to a certain limit, it must be replaced according to the operating procedures of the equipment. When replacing the grinding wheel, it is necessary to ensure that the specifications and models of the new grinding wheel match the equipment, and it should be installed strictly in accordance with the installation requirements. After installation, dynamic balance debugging is also required to ensure the stability of the grinding wheel when running at high speed.

In addition, in order to extend the service life of the grinding wheel, the grinding parameters such as grinding speed and feed amount should be reasonably controlled during the processing to avoid excessive wear of the grinding wheel. At the same time, attention should also be paid to keeping the grinding wheel clean to avoid foreign objects adhering to the surface of the grinding wheel and affecting the grinding effect.

 

III. Transmission System Maintenance: Ensuring Smooth and Stable Operation

The transmission system of the glass double edger mainly includes components such as motors, belts, chains, guide rails, and lead screws. Its function is to accurately drive the workbench and grinding wheel to move to achieve the double-sided processing of glass. The good condition of the transmission system is the key to ensuring the processing precision and efficiency of the glass double edger.

Regular lubrication of the transmission system is an important part of the maintenance work. For parts such as motor bearings, guide rail sliders, and lead screw nuts, appropriate lubricants should be selected according to the requirements of the equipment operation manual, and they should be added or replaced at the specified time intervals. For example, high-temperature grease is generally added to the motor bearings once every [X] months; an appropriate amount of lubricating oil should be dripped on the guide rail sliders every week. When adding lubricants, attention should be paid to cleaning the lubricated parts to prevent impurities from mixing in.

At the same time, the tension of belts and chains should be regularly checked. If the belt or chain is too loose, it will cause the transmission to slip, affecting the processing precision; if it is too tight, it will increase the load on the transmission components and accelerate the wear. Generally, the tension of belts and chains can be adjusted by adjusting the position of the tension pulley, and the inspection cycle is recommended to be once a week. In addition, it is also necessary to check whether there are foreign objects stuck in the guide rails, lead screws and other components, and whether there are scratches or wear on the surface. If there are any problems, they should be cleaned or repaired in time.

 

IV. Electrical System Inspection: Ensuring the Safe and Stable Operation of the Equipment

The electrical system is the "nerve center" of the glass double edger, controlling various actions and operating parameters of the equipment. In order to ensure the safe and stable operation of the electrical system, regular inspection and maintenance are required.

First, it is necessary to check whether there are any damages, aging, short circuits, etc. in the electrical lines. Especially in the parts where the equipment is often moved or vibrates greatly, such as the connection points of the power cord, control line and the machine body, more attention should be paid to the inspection. If the lines are damaged or aged, they should be replaced in time. For the parts that are prone to short circuits, measures such as adding protective sleeves and fixing the lines can be taken to prevent them.

Second, the working state of electrical components such as contactors, relays, inverters, motor drivers should be checked. Check whether these components have abnormal heating, contact erosion, parameter drift and other phenomena. If there are any problems, they should be repaired or replaced in time. At the same time, the dust in the electrical control cabinet should be regularly cleaned to ensure good heat dissipation conditions. It can be cleaned with compressed air or a small vacuum cleaner, and the cleaning cycle is recommended to be once a month.

In addition, in thunderstorm seasons or areas with large fluctuations in power grid voltage, a voltage stabilizer or overvoltage protector should be considered for the glass double edger to prevent electrical components from being damaged due to high voltage.

 

V. Precision Calibration: Maintaining the Stability of Processing Precision and Quality

With the increase in the usage time of the glass double edger, due to the wear of mechanical components, changes in the installation foundation, etc., the processing precision of the equipment may gradually decline. In order to ensure the processing quality of glass products, it is necessary to regularly calibrate the precision of the equipment.

 

Precision calibration work generally includes projects such as workbench flatness calibration, grinding wheel perpendicularity calibration, and grinding size precision calibration. Calibration work requires the use of professional detection tools such as marble slabs, right-angle rulers, and dial indicators. For example, when calibrating the workbench flatness, the marble slab can be placed on the workbench, and the height difference of different positions of the slab can be measured with a dial indicator. According the measurement result, the anchor bolts of the workbench are adjusted so that the workbench flatness meets the requirements.

The calibration cycle can be determined according to the usage frequency of the equipment and the processing precision requirements. Generally, it is recommended to conduct a comprehensive precision calibration once every months. If obvious deviations in the size precision, angle precision, etc. of the glass edge are found during the processing, targeted calibration work should also be done in time.

 

VI. Regular Comprehensive Overhaul: In-depth Inspection and Maintenance of the Equipment

In addition to the daily maintenance work, the glass double edger should also be regularly comprehensively overhauled. The comprehensive overhaul can generally be arranged once a year or the cycle can be appropriately adjusted according to the actual operation status of the equipment.

During the comprehensive overhaul process, each system and component of the equipment should be deeply inspected and maintained. In addition to the above-mentioned cleaning, lubrication, inspection, calibration and other work, it also includes the inspection of mechanical structural parts, such as whether the machine body frame is deformed, cracked, whether the connecting bolts are loose, etc.; the inspection of the cooling system, such as whether the coolant needs to be replaced, whether the cooling pipelines are blocked, etc.; the inspection of the safety protection devices, such as whether the switch of the protective door is flexible, reliable, whether the emergency stop button is normal, etc.

Through regular comprehensive overhauls, potential problems and hidden dangers of the equipment can be discovered in time, and effective measures can be taken to solve them, thus extending the service life of the glass double edger, ensuring the long-term stable operation of the equipment, and providing a powerful guarantee for the glass processing production of enterprises.

 

In conclusion, the maintenance of the glass double edger is a systematic and meticulous work, which requires operators and maintenance personnel to possess professional knowledge and skills and strictly follow the equipment maintenance procedures. Only by doing a good job in daily cleaning, grinding wheel maintenance, transmission system maintenance, electrical system inspection, precision calibration and regular comprehensive overhauls can the glass double edger always maintain a good performance state and create greater economic benefits for glass processing enterprises.
