Cast iron table, also known as iron platform / cast iron plate, fitter table, the machine table for a variety of inspection, precision measurement reference plane, mainly for the dimensional accuracy of the measurement of the mechanical workpiece datum inspection, inspection of parts or deviant behavior, and make precision crossed, in the machinery manufacturing inspection is the most indispensable benchmark measuring plane. Machine table also called cast iron table, cast iron castings machine table, the product is made of high-strength cast iron HT200-250 face hardness of HB160-210. Advantage of the machine table (cast iron table): 1, the lowest temperature coefficient, cast iron table basically not affected by temperature. 2, almost no maintenance, can be quickly and easily clean / wipe, good stability and accuracy. 3, is always the hardest surface. 4, the smooth "bearing" surface, vain earth, wear non-magnetic. 5, precision measuring tools, instruments, using high-quality "Jinan Green" stone grinding machined and hand-made. 6, the machine table (cast iron table) resistant to moisture, corrosion casting machine, not oiled, no rust, no fade. My company has a high level of management, technical force, the detection means perfect, sophisticated equipment, advanced manufacturing technology, product research and development using CAD technology, the company's products are all manufactured in accordance with national standards and processing, non-standard products according to drawings. Product qualification rate has been above 97% since the first half of 2003 reached 98.78 percent pass rate.
