Machine Tool Casting Horizontal bed with a horizontal placement of the turret to improve the accuracy of the movement of the knife, generally used for large-scale CNC lathes or small-scale precision, high precision, easy to operate, The layout of CNC lathes.
Machine casting (bed casting) (large castings) using heat treatment process to eliminate the stress in the casting. Long-term use is relatively stable.
Standard: GB9439-88
Features: Wear resistance, good shock absorption, good process performance, gray cast iron carbon content is relatively high, close to eutectic composition, so the melting point is relatively low, good fluidity, shrinkage is small, more suitable for structural casting complex or thin The castability of the gray cast iron is higher than that of the steel.The high strength of the sand in the early stage of casting is beneficial to the graphitization expansion of the solidification process of the cast iron, effectively eliminating the shrinkage and shrinkage defects , To achieve gray cast iron, ductile castings less riser, no riser casting.
Machine castings (large castings) the relationship between strength and hardness: cast iron hardness and strength of the relationship between the existence of the empirical relationship is:
A. When O≥196N / mm ㎡, HB = RH (flying 00 + 0 4380b) (B1).
B. When 0 ≥796N / mm ㎡, HB = RH (44 + O 7240b) (B2).
Casting machine tool castings, large machine tool castings, gantry machine casting, vertical lathe casting, large castings. Machine tool castings with EPC process. Machine tool castings can reach 80 tons of single weight. Machine casting material gray iron 200, HT250, QT400, ZG450 and so on.

Machine tool bed casting As a large castings to be heat treated to improve their performance and improve the quality of internal heat treatment process is very important in mechanical manufacturing, 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 castings, to improve the use of performance.The purpose of tempering is to eliminate the internal stress quality.

In progress Large machine tool casting , Due to machine tool design shape, wall thickness, cooling speed of different, will be in the machine tool castings, especially large-scale machine tool castings produced within the casting stress.This stress is not eliminated, will cast in the subsequent cutting or use of the process In order to eliminate the residual casting stress, should be used low-temperature annealing process of casting. Casting bed casting process should strictly abide by the tempering process for the deformation or fracture of castings, deformable parts should be added to the support bar; Hand on the back of the furnace thermometer, reasonable control of temperature, to prevent the temperature is too high or too low impact on the casting bed. Machine tool bed casting The product as a large castings must be aging treatment in order to improve their performance, improve the internal quality of machine bed casting in addition to a reasonable selection of materials and a variety of forming process, the heat treatment process is essential .Through the heat treatment process change casting Surface chemical composition, the internal fiber structure, to give or improve the performance of the castings, so that machine tool castings have the mechanical properties, physical properties and chemical properties, and heat treatment generally does not change the shape and overall machine castings Of the chemical composition of machine casting casting method commonly used: clay wet casting sand casting weight from a few kilograms to tens of kilograms, while the dry clay production castings can weigh up to one hundred tons.
