How to choose the best glass edging machine in 2021?
Glass edging machine is one of the earliest and largest amount of mechanical equipment in glass deep processing equipment. With the continuous development and growth of the glass deep processing industry, there are more and more types and specifications of glass edging machines. Today, I will start with the types and characteristics of edging machines, how to choose the best one for 2021, and take you to learn more about glass milling machine!
1. The main types and characteristics of glass edging machine
To choose an edging machine, you must first understand the types and characteristics of the edging machine. The following are the main types:
1. Single-arm special-shaped edging machine (abbreviated as special-shaped machine or single-arm machine)
The main feature of the special-shaped machine is its wide range of uses and low price. The special-shaped machine can grind straight edges, rounded edges, duckbill edges, and beveled edges; it can grind round workpieces, as well as elliptical and special-shaped workpieces. Install the master mold on the independent suction cup, and use the special-shaped machine to grind some irregularly shaped workpieces. The special-shaped machine has a simple structure and relatively low manufacturing cost, so the price is relatively cheap, and the general domestic machine can be bought for about 5000 bucks.
2. Straight-line edging machine
The linear edging machine has three characteristics: one is that it has a single purpose and can only grind all kinds of straight edges; the other is continuous grinding and the production efficiency is high; the third is that it can grind large flat glass. Straight-line edging machine is the edging machine with the most varieties and specifications among all kinds of edging machines. According to the different straight edges that can be ground, it can be divided into the following three types:
(1) Straight edge grinding machine (referred to as straight edge machine)
The straight edge machine can only grind the flat bottom and two corners of the glass. According to the number of grinding heads, there are several models such as three, five, eight, nine, ten, thirteen, and fourteen grinding heads. Generally speaking, the more the number of grinding heads, the higher the grinding accuracy and production efficiency, and the higher the price of the machine. The computer-controlled straight edge machine (generally the number of grinding heads is ten or more) is more expensive. In recent years, a dual-purpose straight edge machine that can grind the bottom edge and 45° bottom edge has appeared in the market, and the amount is relatively large. There is also an edging machine that can grind one or two sets of angled bottom edges, called a multi-stage edging machine. There are many grinding heads of this model, which are generally controlled by computer, and the equipment price is relatively high.
(2) Straight line circle (referred to as round edge machine)
The round edge machine can grind the round edge, duckbill edge of glasses, and it is often used in the processing of furniture and glass. There are also several types of round edge machines, such as three, five, six, seven, eight, and nine grinding heads.
(3) Straight line beveling machine (abbreviated as beveling machine)
The beveling machine is generally used to grind the bevel of 3-20 degrees of glass. Some beveling machines can also grind 45 degrees bevels. The beveling machine is divided according to the number of grinding heads, and there are also models of seven, eight, nine, ten, eleven, and fourteen grinding heads. In recent years, another kind of beveling machine that can grind various wave patterns on the beveling edge of glass, called the wave beveling machine.
3. The profiling machine (referred to as the profiling machine)
The profiling machine uses the template to accurately position, and can accurately grind the straight edges, round edges, duckbill edges, beveled edges of round or special-shaped glass. The glass grinds by this kind of edging machine has accurate shape, uniform size, and higher production efficiency. The use of the profiling machine requires the production of special templates. When there are many types of products, not only the cost of making the templates is higher, but also the management and replacement of the templates are more troublesome. Therefore, this model is suitable for not many varieties of production, but the production volume is very large. The profiling machine also has several models such as single-head, double-head, four-head, and six-head.
4. Internal round edging machine (referred to as internal round machine)
The internal circular machine is characterized by its simple structure and low price, but its use is relatively single. It is mainly suitable for processing the periphery of a circle (it can be a perfect circle, an ellipse or a special-shaped circle). At present, the internal circular machine produced by some domestic factories has a long swing arm, which increases the swing range of the grinding head. This type of machine can not only grind the inner circle, but also the outer circle. It is also called the inner and outer circle edging machine.
5. Straight-line double-sided grinding machine (referred to as double-sided grinding machine)
The feature of the double-sided grinding machine is that it can grind the two opposite sides of the glass at the same time, with good processing accuracy and high production efficiency, which is suitable for mass production of glass edging. According to the performance of the double-sided grinding machine, there are two types: double-straight-edge edging machine and double-round-edge edging machine. Among them, the double-straight-edge edging machine is more common. According to the width of the glass, the double-sided grinding machine can be divided into two types: small and medium size, large size. Those with a maximum grinding width of less than two meters are called medium and small double-sided grinders. The grinding heads are equipped with four, six, eight, and twelve grinding heads. The largest grinding width of two meters or more is called a large double-sided grinding machine. The grinding head is equipped with 16, 20, 22 grinding heads, etc. Large-scale double-side grinders are generally computer-controlled, with a high degree of automation, and are suitable for grinding large-size flat glass. However, this type of equipment is more expensive.
6. Other edging machines and special edging machines
In addition to the edging machines introduced above, there are also some edging machines with simple structure and single purpose, such as chamfering machines, small disc machines, and polishing machines. In addition, there are some special edging machines that specialize in processing certain products, such as car rearview mirror edging machines, wash basin edging machines and so on.
Second, the choice of edging machine
1. Choose a manufacturer
Although there are nearly a hundred manufacturers of edging machines out there, there are only about 10 manufacturers like Trueprocnc with large production scale, stable product quality, perfect after-sales service system and high reputation. You must choose these manufacturers first when buying. In addition, if you need to purchase more types and quantities of edging machines, it is best to use the same manufacturer.
2. Choose the type of edging machine
There are many types of edging machines, and how to choose depends on the characteristics of the processed products and the scale of production.
Taking the rounding machine as an example, the edging machines that can grind the rounded edges include special-shaped machines, linear rounding machines, profiling machines, and straight double-sided rounding machines. How to choose must be combined with the requirements of processed products. If the designed and processed product is round, oval or other special-shaped glass, you can only choose a special-shaped machine or a profiling machine (because the straight-line rounding machine cannot grind round or special-shaped workpieces). If there are many types of products designed and processed and the batch size is small, it is more appropriate to choose a special-shaped machine; if the types of products designed and processed are small and the batch size is relatively large, it is more appropriate to choose a touch machine. If the designed and processed product is rectangular or rectangular glass, you can only choose straight-line round-edge machine or straight-line double-round-edge machine (because special-shaped machines and profiling machines generally cannot grind straight-line round edges). When the product accuracy requirements are not very high and the production batch is not too large, you can choose the general straight edge rounding machine (because its price is lower); if the product accuracy is high and the production batch is also large, choose the straight double-sided circle Edge machine is more suitable.
Third, the use of edging machine
The correct and reasonable use of the edging machine can not only ensure the normal production, but also prolong the life of the machine. Here is an introduction to the matters needing attention in the correct use of the edging machine.
1. For all newly purchased edging machines, be sure to read the instruction manual before using it. After understanding the transmission principle of the machine, the functions of various handles, handwheels, electrical buttons, waterway and airway regulating valves, and mastering the knowledge of machine maintenance, you can operate the machine.
2. The quality of the grinding head of the edging machine has a great influence on the grinding quality of the glass. The position of the grinding head and the moving gap have been adjusted before leaving the factory. Generally, do not move the rest except the forward and backward grinding heads during use. , So as not to affect the grinding quality. In addition, the back position of the grinding head is not easy to be too large, otherwise the waterproof cover will be easily damaged, causing water leakage, and the motor is likely to burn out.
3. Adequate cooling also has a greater impact on the grinding effect. Always check the cooling pipeline for blockage. Especially the pipeline of the linear edging machine is easy to be blocked by the bristles, and it is not easy to be noticed after blocking, which will cause insufficient cooling and affect the quality of edging.
4. The CVT used by the edging machine must be in the open state when adjusting the speed, otherwise the CVT of the edging machine will be easily damaged.
5. Precautions when using the special-shaped machine: ① Whether the height of the suction cup of the special-shaped machine worktable is consistent has a greater impact on the grinding effect. When assembling, the manufacturer has carried out self-grinding on the five sets of suction cup holders, and selected the suction cup glue with the same thickness to keep the height of each suction cup consistent. Therefore, do not disassemble the suction cup under normal circumstances. If the suction cup glue is damaged, you must choose the same thickness to replace it. ②After the vacuum pump of the special-shaped machine is used for a period of time, the vacuum degree will drop (that is, the suction power will drop) due to water intake and other reasons. Therefore, pay attention to check and eliminate the fault. Otherwise, the machine will work under the condition of insufficient suction, which will affect the grinding quality, on the other hand, it is also prone to safety accidents.
6. Precautions when using the linear edging machine: The working method of the linear edging machine (straight edge machine, round edge machine, beveling machine) is to clamp the glass through the front and rear pressure plates and drive its linear motion for grinding. Two points must be paid attention to during use: ①The joint surface of the front and rear pressure plate and the guide rail should be frequently lubricated, otherwise the normal service life of the machine will be affected due to the premature wear of the front and rear pressure plate and the working surface of the guide rail. Although some models have automatic lubrication devices, you should always check whether the lubrication pipeline is unblocked; ②The clamping force should be appropriate when clamping the glass, too loose will affect the grinding quality, and too tight will increase the load of the machine, which is easy to produce the phenomenon of shaking and crawling, it is easy to pinch the glass when the glass is thinned. The clamping force can be tested with a slightly larger glass clamp on the machine, that is: clamp the glass in the middle of the machine, move the glass with both hands in the stopped state, and feel that the clamping force is adjusted to the degree when the hands can't move it.
7. Precautions when using the profiling machine: ①The profiling of the profiling machine has a great influence on the grinding accuracy. The working surface that depends on the template must be made of accurate shape and size, and the finish must be high. If it is shaped by template, the transition must be smooth. ②When replacing the template and the suction cup, be sure to keep the working surface of the suction cup level, otherwise the grinding quality will be affected.
8. Precautions when using the double-side edging machine: ① The double-side edging machine is a higher-grade edging machine. It is best to appoint two or three people to operate it to ensure correct operation. ②When there is an error or failure in the procedure of the double-side grinding, it is best to ask the original manufacturer to send someone to repair and debug. Under normal circumstances, do not disassemble and repair, so as not to mess up the procedure and cause the production to stop.
