Said into the electric tool grinder, there are generally two types of specifications, the short side of the fuselage switch type switch models with long handle refers to the fuselage. Often use big short version, the main common place for industrial grinding and cutting use. For grinder performance quality, 'a worker who continued to work sites were deeply understand:' carry stand, stand, high efficiency, long life 'and his focus points. Grinder status quo in the face of the traditional series motor on market Angle grinder, actual show in daily use, such as: multiple frequency change replace carbon brush, bearing, change of rotor, gear replacement and so on maintenance, be plagued by serious matter of the users in the process of using bother; And greatly increased the use cost of users, but also weaken the use value and it is difficult to achieve excellent cost effectiveness. Therefore, short shank type short power volume limitations; Long handle model by adding the practice of power increase volume, is neither desirable is wasted. So, in contrast, all of the grinder on the market, there are all kinds of short plate with each other. Strictly speaking, can reflect the superior performance and at the same time to excellent cost effectiveness has so far been outstanding models. As an integral part of hand-held electric tools how to effectively when it comes to boost industrial manufacturing? Intelligent tool, the essential difference between intelligent tool since the project will focus on the whole series brushless tools product research and development, and based on the independent core technology 'high speed high power density of single-phase plug-in brushless dc motor' this thing in the application of blank, started from mechanical reversing crossover to single-phase plug-in electronic commutation brushless dc electric tools. Also take the lead to achieve the breakthrough of traditional industry products intelligent tool series products. Intelligence tool concentrated in two aspects namely technical advantages and outstanding character, it has essential difference with the traditional electric tools. Place for Angle grinder application and practice analysis, the two aspects of working condition can clear on the product quality results. In the process of industrial application of Angle grinder, involved in the concentration of several application condition of the actual demand. Main use end: group users and the requirements of industrial use 1, large job shop place and large workpiece grinding work this kind of user is the mainstream of Angle grinding machine. Its characteristic is according to the division of daily production plan and shift operation dimensions, regularity of industrial use place. Use the type of work are heavy load type continuous operation, as well as in many objects for the workpiece in the grinding metal 'grinding' work as the goal of workers to work. Angle of grinding machine installation work in 'fiber resin colophon grinder' as the auxiliary materials. Gradually with the grinding wheel to the development trend of hard, will be directly diagonal mill overall performance quality put forward more requirements of the test. 2, and casting workshop and large workpiece grinding this kind of place in the workplaces where dust is relatively serious, grinding workpiece size is large, using load demand is bigger, continue to work for a long time, the environment temperature is higher. This is also the comprehensive performance of harsh consideration Angle grinder and durability using typical user place. Many ordinary grinder pass almost did not escape the life of the cycle time. Conclusion: on the mainstream use ordinary grinder are no exception, are to face, users in the use of the actual needs are not being met. The root of the problem mainly from three important aspects: one is the performance of the electric tool itself defects; The second is complementary makings quality selection and correct use. 3 it is caused by heavy load sustainable use high frequency fault as well as the use of high cost. The traditional electric tool comparative analysis of the traditional electric tool problem (A)How to achieve high quality cheap products? (2)Brand models how to break through the mechanical commutation of traditional technology bottleneck? (3)High temperature rise, in carbon brush, bearing, change the rotor, changing gear that is discarded. (4)Purchase cost-effective, the use of the high cost. The main performance parameters, the input power: W -, the output power between W: W -Work, stable power between W: W -(between WHead shell hot engine temperature high)Turn, no-load speed: -R/per minute (Heavy load falling damage % above), power supply frequency: HZ note: instantaneous power and high can continuous load assignment, or burning machine. In the use of these heavy load continuous operation based on the above, it is because the ordinary models cannot meet the needs of users, so will only be because power is too small and short shank type with long handle model; Because machines continuous hot avoid burning machine, the user can only be seen configuration exchange using two machines. A superior model, has been the mainstream user groups waiting handy thing in the world; Reality is the biggest key: many people overcome difficult have failed to satisfy the grinder achieve this type of the actual needs of users.
