Table as an important part of the machine, but also affect important aspects of machining accuracy. Present a wide variety of table, traditional table can only be installed on a particular machine, along with science and technology with the times, their function is also from the traditional to the modern multi-unitary nature of the development of better, and now some of the work Taiwan, which not only can be installed in drilling, but also can be installed in the milling and boring machine and other machines. Through the design table, learn equipment modification program development, comparison, analysis, and perform the necessary calculations; through the transformation of the mechanical parts of equipment design, control equipment, a typical part of the calculation methods and procedures and the right architecture design; by design , establish the correct design ideas, develop their own ability to analyze and solve problems; to improve their application notes, standards of competence.  The design table is designed using low friction linear guides and pre
