The fully automatic horizontal glass four-sided linear edging machine is divided into three parts: the film entry table, the edge grinding frame, and the film discharge table. The film entry table and film exit table are used in conjunction with the edge grinding frame to grind glass. The edge grinding stand has 2 sets of grinding heads. Each group of grinding heads has two grinding wheels. The edge grinding process is simple. First, grind the head of the glass, then rotate the grinding head 90 degrees, and use the grinding wheel on the side to grind both sides of the glass. After that, the grinding head rotates 90 degrees again to grind the tail of the glass. , complete the entire edge grinding process. After grinding, the rotation returns to zero and waits for the next piece of glass to be ground. The craftsmanship is smooth and natural, and the fit is tight. It compresses the edge grinding time to the maximum extent and greatly increases the speed of glass edge grinding.

Glass edge grinding machine is one of the earliest and most widely used mechanical equipment among glass deep processing equipment. In recent years, with the continuous development and growth of the glass deep processing industry, there are more and more types and specifications of glass edge grinding machines, and the technology is becoming more and more advanced, and the functions are becoming more and more comprehensive. So, as a glass deep processing practitioner, how to choose the model that suits you among the wide variety of glass edge grinding machines? And how to use it correctly and reasonably?

To choose an edging machine, you must first understand the types and characteristics of the edging machines. The main types of glass edging machines are as follows:

1. Single-arm special-shaped edge grinding machine (referred to as special-shaped machine or single-arm machine), which can grind straight edges, round edges, duckbill edges, and bevel edges; it can grind round workpieces as well as Oval and special-shaped workpieces. Install a template on the independent suction cup and use a special-shaped machine to grind some irregularly shaped workpieces. Its structure is simple and the manufacturing cost is relatively low, so the price is also relatively cheap. Generally, domestic machines can be purchased for about 20,000 yuan.

2. Linear edge grinding machine. The linear edge grinding machine has three characteristics: first, it has a relatively single purpose and can only grind all kinds of straight edges; second, it can grind continuously and has high production efficiency; third, it can grind larger sizes. of flat glass.

Linear edge grinding machine is the edge grinding machine with the most varieties and specifications among all types of edge grinding machines. According to the different straight edges that can be ground, it can be divided into three types: linear edge grinding machine, linear circle edge grinding machine, and linear bevel edge grinding machine.

3. The template edge grinding machine can accurately position the template and can accurately grind the straight edges, round edges, duckbill edges, bevel edges, etc. of round or special-shaped glass. The glass produced by this edge grinding machine has an accurate shape. Uniform size and high production efficiency. This type of machine is suitable for glass processing that produces a small number of varieties but a large production batch. When purchasing, we must first choose edge grinding machines produced by manufacturers with larger production scales, stable product quality, complete after-sales service systems, and high credibility, because although the edge grinding machines produced by these manufacturers are more expensive than those produced by small factories, It is a bit higher, but the quality and after-sales service are much better than those of small factories, so you can feel more confident when using them. Even if there are some technical problems during use, these manufacturers will help you solve them in time. Generally, it is free during the warranty period, and the cost will be charged appropriately after the warranty period. In addition, it should be noted that if there are many types and quantities of edge grinders to be purchased, it is best to choose ones produced by the same manufacturer. This is because it will be much more convenient for future production, management, maintenance, etc., and because it is purchased in bulk, you can get more discounts on price and service.

4. Internal circular edge grinding machine. The internal circular edge grinding machine is characterized by its simple structure and low price, but its use is relatively single and it is mainly suitable for processing the periphery of circles.

5. The linear double-edge grinding machine is characterized by being able to grind two opposite sides of the glass at the same time. It has good processing accuracy and high production efficiency. It is suitable for large-scale glass edge grinding production. Double-sided grinders can be divided into small, medium, and large types according to the different widths of glass grinding. Those with a maximum grinding width of less than two meters are called medium and small double-sided grinders. Those with a maximum grinding width of two meters or more are called It is called a large double-sided grinding machine, and its grinding heads are equipped with sixteen, twenty, and twenty-two grinding heads, etc. Large-scale double-sided grinding machines are generally computer-controlled have a high degree of automation and are suitable for grinding large-sized flat glass. However, this equipment is relatively expensive.

6. Other imported edge grinding machines. Imported machines have good quality, and high precision, and their production efficiency and service life are much higher than domestic machines. However, imported machines are expensive, generally 3 to 10 times the price of similar domestic machines.

When choosing an edge grinder, you should pay attention to the following matters. When purchasing a machine, make a careful selection. It is best to ask the manufacturer to test-grind several types of glass with different thicknesses and sizes. In addition to observing the quality of the glass after grinding, you should also observe whether there are any abnormalities during the operation of the machine (such as vibration, water leakage, etc.). If any problems are found, the manufacturer must promptly solve them or make changes. When purchasing new equipment, relevant personnel in the factory should be sent to participate in the equipment operation training provided by the glass machinery factory, so that they can operate correctly and maximize the effectiveness of the equipment when used in the future. Sufficient spare parts are available to ensure production. When purchasing a machine, purchase more necessary accessories (such as pressure plates, suction cup glue, waterproof covers, and other vulnerable parts) to eliminate the impact on production caused by insufficient spare parts during the use of the equipment.
