Machine tool castings More for the bed, columns, beams, bases its reasonable structure, process performance, processing more convenient. horizontal bed accompanied by horizontal accuracy of tool holder tool holder-raising campaign, generally used for large or small sized precision CNC lathe CNC lathe layout.
Machine tool castings (bed casting) (castings) using heat treatment processes, eliminate internal stress. more stable to use for a long time.
Standard: GB9439-88
Features: wear, elimination earthquake sex good, process performance good, gray mouth cast iron containing carbon volume than high, close Yu total crystal components, so melting point compared low, liquidity good, contraction rate small, more suitable Yu structure casting complex or thin-walled casting. graphite makes cutting processing Shi easy formed broken chip, gray mouth cast iron of can cutting processing sex to above steel. pouring early sand type strength high conducive to cast iron solidification process of graphite of expansion, effective to elimination shrinkage, shrink pine defects, achieved gray cast iron, ball ink casting less take mouth, no take mouth casting.
Machine tool castings (castings) relationship between strength and hardness: relationship exists between the hardness and strength of cast iron, and its empirical formula is:
A ... When you o more than 196N/mm square meters and HB=RH (fly 00+0 4380b) (B1).
B. When 0 ≥ 796N/mm square meters, and HB=RH (44+O 7240b) (B2).
Foundry machine castings, large machine tool castings, gantry machine tool castings, vertical lathe machine tool castings, castings. machine tool castings in lost foam casting process. single weight up to 80 tons of machine tool castings. 200,HT250,QT400,ZG450 machine tool castings made of grey iron and so on.

Machine tool bed castings As a large cast to undergo heat treatment in order to improve their performance, improve inner quality. heat treatment processes is very important in machinery manufacturing, compared to other processing, heat treatment does not change the shape of the workpiece and the overall chemical composition, by changing the internal quality of the workpiece, changing the chemical composition of castings, to improve performance. the purpose of tempering is to eliminate internal stress quality.

Our products are divided into two series:

(1) heavy machinery products: various models of the new type single or double column vertical lathe, test pads box, designed and manufactured according to customer needs. heavy, large, medium size CNC machine tool, vertical lathes, machine tools, metal bed, non-standard casting machine tool bed castings, beam gantry milling machine, cast iron mechanical slide unit; Boring machine bed castings, bearing cast, fencing wire base, with heavy iron, nodular casting, the road squats, weight iron and other products of the processing system design and installation.
(2) machine measuring: cast iron flat platform, Assembly flat, carved line flat, cast iron table, cast iron set disc, fitter underlined platform, test flat, welding flat, riveting welding flat, marble flat, machine table flat feet, party box, aluminum magnesium flat feet, granite flat, granite measuring, flat feet, square, feet,, machine pad iron (adjustment pad iron, earthquake pad iron)
