The machine tool bed castings are made of high-wear-resistance gray cast iron. By adopting a process that combines secondary artificial aging with natural aging, the internal casting stress is deeply eliminated. This controls the straightness error of the bed guideway surface within 0.005mm/m, providing stable benchmark support for the machine tool and effectively avoiding machining precision deviations caused by bed deformation.
Structurally, a staggered design of multiple transverse and longitudinal reinforcing ribs is adopted to enhance the overall rigidity of the bed. It can withstand the huge impact force and high-frequency vibration generated during the machine tool's cutting process, suppress bed deformation, and ensure the dimensional precision stability of the machine tool during long-term operation.
In addition, the mating surfaces of the bed castings with sliders and lead screws undergo precision milling and lapping processes, achieving a surface roughness of Ra0.4μm. This improves the fit with supporting components, reduces transmission gaps, further enhances the operational stability of the machine tool, and helps customers achieve efficient and high-precision machining production.
Our company has a raw material storage workshop of approximately 1,200 square meters, a model-making workshop (woodworking shop) of about 500 square meters, a casting workshop of around 4,000 square meters, a machining workshop of roughly 2,800 square meters, a heat treatment workshop of about 1,600 square meters, an office area of approximately 500 square meters, an environmental protection and public facilities area of around 1,500 square meters, and a reserved development area of roughly 1,300 square meters.
Our company is equipped with 2 medium-frequency induction furnaces (10 tons each), 1 bogie-type heating furnace (4m × 4m × 30m), 2 5-meter 5-axis gantry milling machines, and 3 2.5-meter vertical lathes. Its cooperative laboratory is capable of conducting chemical tests (including composition analysis and metallographic analysis) and is furnished with tension and impact testing equipment certified by ASME.
