Want to choose edge grinding machine, first to edge grinding machine understanding the type and characteristics. For doubleedge grinding machine machine model at present domestic no unified layout norms, so this paper no longer lists mechanical model. 1, single-arm abnormity doubleedge grinding machine (hereinafter referred to as abnormity machine or single arm machine) The biggest characteristic of special-shaped machine is used widely, the price is cheap. Abnormity machine can grind straight edge, also can ground round edge, duck lips, still can grind tapered side plain wheels; Can grind workpiece, also can whet circular ellipse and abnormity workpiece. In independent chuck modeling, filled with special-shaped machine can grind some irregularly shaped workpieces. Abnormity machine simple in structure, manufacture relatively low cost, so the price is cheaper also, general GuoChanJi two thousand yuan can be bought. 2, linear edge grinding machine The characteristics of linear edge grinding machine has 3: it is to use more onefold, grinding various linear edge; only 2 it is grinding, the production efficiency can be continuity higher; Three is bigger flat glass grinding size. Linear edge grinding machine is all kinds of edge grinding machine kinds and sizes most doubleedge grinding machine, according to the edge of the straight line can grinding different, it can divide again as follows three: (1) linear edge grinding machine (hereinafter referred to as straight edge machine) Straight edge machine can only grinding glass edges and flat, according to two edges, there are three grinding head count points, five, eight, nine, ten, 13, 14 ground top several models. Generally speaking, grinding head count is more, grinding accuracy and efficiency of the machine is taller, accordingly the higher price. And computer control straight edge machine (general mill in ten or are broken down by more than ten) is the price higher. In recent years, domestic market appeared again a kind already may be grinding pan edge, and may be grinding 45 ° hemline amphibious straight edge machine, dosage is more also. Another can whet a group or two groups to each Angle hemline is edging machine, called multi-stage edge grinding machine. This machine for grinding head more, general computer control, equipment value is relative taller. (2) linear circular (hereinafter referred to as round margin machines) Round the edge roller can grinding glass edge, duck lips round in furniture, glass processing with more. Circular edge machine also has three, five, six, seven, eight, nine ground top several models. (3) linear beveling machine (abbreviation beveling machine) Beveling machine for grinding commonly 3 ~ 20o of the hypotenuse of glass. Now, some beveling machine can also be grinding 45 ° of the hypotenuse of. Beveling machine press grinding head count points, also has seven, eight, nine, ten, eleven, fourteen grinding top models. In recent years and appears on a glass on the hypotenuse of wave patterns of grinding, beveling machine called wave beveling machine. (4) linear bilateral doubleedge grinding machine (hereinafter referred to as bilateral mill) The characteristics of bilateral grinding machine is also the two edge grinding glass, processing precision, high production efficiency, suitable for large quantities of glass edging production. Bilateral mill by use performance points have double straight edge doubleedge grinding machine and double circular edge doubleedge grinding machine two kinds, including double straight edge doubleedge grinding machine with more. Bilateral mill press grinding glass width can be divided into two kinds of medium and large. Biggest in two meters below the grinding width called medium and small bilateral grinding machine, grinding head configuration has four, six, eight, and twelve ground top. Biggest in two meters and grinding width two meters above called large bilateral mill, grinding head configuration has 16, 20, 22 ground top. Large bilateral mill is commonly computer control, automation degree is higher, suitable for grinding large size plate glass, however, this equipment are expensive. Three, inner circle edge grinding machine (abbreviation is semi-atuo machine) The characteristics of semi-atuo machine is simple in structure, low prices, but it is a single, mainly is suitable for machining circle surrounding (may be positive, but oval or round profiled circle). Now the domestic some factory in circular machine, swinging arm longer, make grinding head swinging increased range. This model not only can whet, also can hold concurrently semi-atuo external circular grinding, also known as inside and outside round edge grinding machine. 4, other edge grinding machine and special edge grinding machine In addition to the above the edge grinding machine is introduced, besides some simple structure, USES a single edge grinding machine, such as chamfering machine, small round slice machine, polishing machine, etc. There is also some special processing some product special edge grinding machine, such as auto rearview mirror edge grinding machine, lavabo doubleedge grinding machine, etc. 5, import edge grinding machine JinKouJi high precision, good quality, efficiency and service life is much higher than domestic machine. But JinKouJi expensive, generally for domestic similar machine price 3 ~ 10 times. Import doubleedge grinding machine from Italy production more, quality is better also. Another comes from South Korea and Taiwan with the edge grinding machine and more. 6, modeling edge grinding machine (abbreviation modeling machine imitation shape machine) Modeling machine using the template accurate positioning, can accuracy grinding round or shaped glass straight edge, round the edges, duck lips, beveling etc, this edge grinding machine grinded glass shape accurate, high efficiency unification, the production size. Use modeling doubleedge grinding machine needs to prepare special template, when production of a long, not only higher cost of making stencil and management, replacing template also a trouble, so the machines are suitable for production of small, but production batch big glass processing. Modeling machine is also a single head, double head, four, six top several models, including four and six modeling machine can be a grinding now domestic doubleedge grinding machine manufacturers have nearly hundred, but which produce larger scale, stable product quality and after-sales service system, credibility higher manufacturers only more than 10 factories, we should first choice when buying these manufacturers doubleedge grinding machine, for these factories though edging machines in price than small factory is higher, but the quality and after-sales service to much better than the small factory, more comfortable with it. Even in use appear some technical problems, these manufacturers will also help you out in time. General under warranty are free, charge cost warranty appropriate. If already purchase of machinery and equipment are not satisfied, can also return or replacement. In addition to special explanation is, if you want to buy doubleedge grinding machine type and quantity is more, had better be to choose the same manufacturers. Because doing so in the future production, management, maintenance, and convenient because many are batch purchase in price and service, also can get more favorable, the author for many glass products factory understand found, many manufacturers use production equipment are produced in a handful of equipment factory. If the glass products grinding accuracy requirement is not too high, can consider to buy a small factory edge grinding machine. This saves purchased equipment investment, because of the small factory price relatively cheap, machine than giant general can production low 10% ~ 20%. If the glass products processing, the larger scale, and more sufficient funds to glass products, production batch of high accuracy requirement, can consider buying a big several imported edge grinding machine. JinKouJi though expensive, but it high machining accuracy, low failure rate, the key moments to play advantage. Some manufacturers of imported doubleedge grinding machine used ten years still in use, and the processing precision is still better than domestic machine high. So in a sense to buy JinKouJi is quite cost-effective.
