Boring and milling machine milling machine, also known as flat-bed table, boring and milling work units, mainly used for machining the work plane, above the hole and the T-slot, for a fixed workpiece, and iron filings produced when cleaning processing. Floor boring machine table of the chemical composition of the casting line HT250 standards and achieve the mechanical performance test standards. 
 Material: high-strength cast iron HT200-300 face hardness of HB170-240, after two manual processing (annealing 600 degrees -700 degrees artificial and natural aging 2-3 years) use of the product accuracy and stability, good wear resistance. 
 Casting, the outside does not allow loose, blisters, pores, slag, cracks and other casting defects. 
 Foundry furnace of the casting were well marked with the same number in One piece oven with cast test bars. 
 Each furnace test bars were doing chemical analysis and mechanical properties testing, and issue a valid report. 
 Casting non-machined surface to clear the sand. Etc. 
 Accuracy of drawings produced by three of the milling machine table (flatness and straightness of the standard T-slots for the state three criteria, namely, two standard 2-fold), as the level of flatness can be detected together, T-slot straightness ray tube collimator can be detected. 
 Table surface may not have serious impact on the appearance and performance of the sand hole, holes, cracks, slag, shrinkage, scratches, bumps and other defects. 
 Boring and milling machine is used as a dedicated platform for the cast iron table boring machine platform. Boring machine is mainly used in boring tool boring machine on the workpiece, usually, boring tool rotation-movement, boring tool or workpiece movement of the feed movement. Its precision and surface quality than drilling. Boring is the major processing parts of large equipment box.
