Vertical lathe casting Also known as castings, large bed casting, a large gray iron castings, gray iron castings, machine tool bed standard, GB9439-88.

, Bed standard: GB9439-88

Second, the bed features:

(1) good wearability and weakening. As in cast iron with graphite to lubricate and oil storage, good resistance to abrasion. Similarly, due to a weakening of graphite is better than that of steel.

(2) process performance. Because of the high carbon content in cast iron, close to the eutectic composition, low melting point, good liquidity, shrinkage, so suitable for casting complex structures or thin-walled castings. In addition, because of easy to form graphite machining chip breaker, machinability is better than that of grey cast iron and steel. This factory also produces machine bed, large casting, State car castings and other castings products.

Gray cast iron Mainly used for machine parts and blanks, precision castings, can also be used directly as parts of the machine. Casting machinery products accounted for a large proportion, such as tractors, casting weight around the weight of 50~ 70%, 40~ 70% of agricultural machinery, machine tools, internal combustion engines up to 70~ in 90%. In all types of castings, castings of machinery most varieties, the most complex shapes, had the greatest amount, accounting for about 60% of casting production. Followed by metallurgy moulds and engineering pipeline.

Machine tool castings tempering purposes are as follows:

1. reduce brittleness, eliminating or reducing stress, there is a chamfer steel after quenching stress and brittleness, if not to temper tends to cause deformations in the steel and even cracking.

2. to obtain the required mechanical properties of the workpiece and workpieces quenched hardness and brittleness in order to meet the different requirements of various artifacts, can be adjusted by appropriate tempering tie to hardness, decreases brittleness and toughness needed to get the plastic.

3. stable size

4. annealing to soften some of the alloy steel, hardened (or fire) is often used after tempering, make appropriate aggregation of carbide in steel, to reduce the hardness to facilitate cutting.

5 machine tool castings production also needs normalizing
