The Difference Between Grinding Machine And Milling Machine

Grinding Machine is mainly used in the super precision machining, in the process of super-precision processing, grinding machine is a common and very important processing methods, and his advantage is that the fine level of processing is very high, the scope of the processing materials is very broad. But the traditional grinding methods also have many drawbacks: such as processing efficiency is very low, the processing costs are relatively high, processing precision still with gaps and processing quality with instability and so on shortcomings. The mill is very widely used in the grinding and processing of mineral materials within the metallurgical, chemical, building materials, mining and other variety of the fields.

Which the control system in the grinding machine, the use of PLC technology as the core of the main control, mainly through text display interfaces for human-computer dialogue. Through the dialogue of this interface and machine, the machine gives more accurate information in the maintenance, operation, there are failures, and other aspects of the equipment; man-machine dialogue interface more intuitive and convenient, simple control of the program, there are very simple to manipulate. Full consideration to the manipulation of people not particularly under normal conditions of misuse, it's operation has no effect. Able to reach a new type grinding machine has improved compared to conventional grinding machines exist a variety of shortcomings, to effectively improve the overall level of the grinding process, to ensure the quality of finesse are processed in the processing of the grinding machine also a significant processing cost of greatly reduced, further increase the overall efficiency of the processing, making grinding technology to further the practical use, it can be more conducive to the promotion and application of the grinding machine, the effective promotion precision processing technology, advanced manufacturing technology development, greatly enhanced the strength to compete in the processing manufacturing industry, especially for revitalizing the northeast old industrial base has a very important significance.

The mill is widely used in the milling and processing of materials within the fields of metallurgy, chemicals, building materials, mining and other minerals. It is mainly based on a variety of different materials in the original fine required by discharging materials fineness, milling machine can be divided into Raymond mill, high pressure hanging roller mill, high pressure micro-powder mill, Straight Centrifugal Grinder, Super Pressure Trapezium Mill, three-ring medium speed mill these six kind types.

The maintenance of vibration grinding machine

Today, there are an increasing number of processing enterprises in the production process applied to the vibration Chemical Equipment. In the operation process of the normal vibration grinding machine, generally do not carry out routine maintenance and maintenance, so long down, vibration grinding machine will be some failures, which delayed the normal production work, affecting work efficiency, improve enterprise production and processing costs, reducing the company's profit margins, making the products in the market and declining competitiveness, which is not conducive to good development.

According to all the experience obtained in the process of production operations in the use of vibration grinding machine, we concluded that the following must be noted that maintenance issues:

The core components of the vibration grinding machine is the vibration motor, a vibration grinding machine failures are mostly motor abnormalities, so we have to be concerned about the routine maintenance of the motor vibration grinding machine. A special motor is the motor of the vibration grinding machine, it requires great attention to the lubrication of motor bearings, the use of lubricating oil must be appropriate, the use of lubricants more each week to give him a shot once a high-temperature lubricants. The small vibration grinding machine, its capacity in 50 to 150 liters, lubricant each time the best injected into the 100CC is appropriate, the Dayou gun to squeeze 30 or so; medium vibration grinding machine, it capacity of between 150 to 350 liters of lubricants each injection to 200CC is appropriate, that is, extrusion in Dayou gun case 60 under; large vibration grinding machine, its capacity of 350 liters more each lubricating oil should be injected to the 300CC is appropriate, that is, extrusion in Dayou gun case 90 under.

In addition, the power cord of the vibration grinding machine motors need to be reinforced, waterproof, and other measures to increase the power cord should pack a layer of waterproof and wear-resistant hose, this can prevent the power cord to be worn, resulting in leakage phenomenon of trip Basket Mill equipped with a frequency converter, be sure to ground wire.

The analysis of three main grinding polishing techniques

At present, the types of Wet Grinding and polishing products are very many on the market, from the technical principle, usually we can approximately divided them into three types:

First, physical grinding. Finished by physical grinding the grinding particles of irregular diamond-shaped state, finesse types of machines ranging from coarse to fine at all levels are relatively complete, and very good physical grinding. Oxidation scratches effect, is the market mainstream grinding and polishing technology. With angular coarse abrasives will always be making unnecessary secondary minor scratches to produce, which requires the operator to a grinding, or two or more grinding in operation, you need more detailed down makes the program very complex, and at the same time inevitably cause a certain degree of damage on the paint. Too frequent use of such abrasive Super Mill, can cause the paint is more dependent on the polishing and waxing, varnish layer will be further behind the thinner, making the brightness of the original paint greatly reduced.

Second, the physical grinding and covered grounding. Through physical grinding and covered grinding to grind out the finished products, just throw after crude scratches hour gone, and accompanied by a bright effect, but in the sunlight, there will be more obvious minor scratches on the optical rotation have occurred the reasons for this phenomenon, a considerable portion of the scratches on the wax or oil composition of the resin filled, not the true meaning removal, because of oil is too large, polished hair ball movement routes would make its produce the optical rotation lines. This polishing is very easy cleaning two or three times, scratches will be the re-emergence, has strong nature of the deception induced.

Third, compare the top rare grinding technology, delay broken polishing techniques. Broken abrasive polishing techniques showed a delay of round glass beads, will not cause secondary grinding scratches on the surface of the workpiece, while the temperature of the paint is not able to effectively carry out a more subtle and deep polishing, this polishing technology to ensure the effect, Basket Mill is also the maximum possible reduction in polishing paint damage.
