Machine tool castings It is more suitable for large-scale workstations. The bed, pillars, beams, and pedestals have reasonable structure, good process performance and convenient processing. The horizontal bed is equipped with a horizontal tool holder to improve the movement accuracy of the tool holder. Large CNC lathes or small precision CNC lathes layout.
Machine tool casting (bed casting) (large castings) using heat treatment process to eliminate the stress within the casting. Long-term use up more stable.
Standard: GB9439-88
Features: wear resistance, shock resistance is good, the process performance is good, gray cast iron carbon content is relatively high, close to the eutectic composition, so the melting point is relatively low, good fluidity, shrinkage is small, more suitable for structural casting complex or thin Wall castings. Graphite makes the cutting process easy to form chip breaking, gray cast iron cutting workability is higher than the steel. Casting early sand strength is high in favor of cast iron solidification process of graphitization expansion, effectively eliminate shrinkage, shrinkage defects , To achieve gray cast iron, ductile castor less riser, no riser casting.
The relationship between the strength and hardness of the machine tool castings (large castings): the correspondence between the hardness and the strength of the cast iron, and the empirical relationship is:
A. When O ≥ 196N / mm ㎡, HB = RH (fly 00 + 0 4380b) (B1).
B. When 0 ≥ 796N / mm ㎡, HB = RH (44 + O 7240b) (B2).
Casting Machine Tool Casting, Large Machine Tool Casting, Gantry Machine Casting, Vertical Machine Tool Casting, Large Casting. Machine Tool Casting Uses Die Casting Process. Machine Tool Casting Weight can reach 80 tons. Machine tool casting material gray iron 200, HT250, QT400, ZG450 and so on.

Machine tool bed castings As a large casting to be heat treated to improve its own performance and improve the inherent quality of the heat treatment process is very important in the manufacture of machinery, compared with other processing technology, heat treatment does not change the shape of the workpiece and the overall chemical composition, by changing The internal quality of the workpiece, change the chemical composition of the casting, to improve the use of performance. The purpose of tempering is to eliminate the internal stress quality.

I plant products are divided into two series:

(1) heavy machinery products: various types of new single and double column vertical lathe, test car box, according to the needs of customers design and production.
