Large scale grinding equipment processing refers to the process of efficiently and precisely machining the surface of workpieces with large dimensions, significant weight, hard materials, or complex structures using specialized grinding machines with high rigidity, high power, and high precision. This type of processing is widely used in fields such as energy equipment, aerospace, shipbuilding, heavy machinery, and rail transportation. Typical objects include water turbine rotors, gas turbine casings, large gear shafts, wind turbine spindles, nuclear power pressure vessel flanges, etc.
The stable grinding of large workpieces relies on the comprehensive capabilities at the equipment system level. Firstly, the machine tool body needs to have a large load-bearing capacity and excellent thermal stability, usually using an integral cast iron bed, a double column symmetrical structure, and an active temperature control system; Secondly, the grinding wheel spindle must balance high torque output and micrometer level rotational accuracy, often equipped with high-power electric spindles or hydrostatic bearing systems; In addition, intelligent CNC systems need to integrate multi axis linkage, adaptive feed, real-time error compensation, and online grinding wheel dressing functions to cope with process challenges under long stroke, variable curvature, and low rigidity working conditions.
Process optimization is the core link to ensure processing quality and efficiency. For different materials such as high-strength alloy steel, nickel based high-temperature alloys, or composite materials, it is necessary to match specialized abrasives (such as CBN or diamond), reasonable particle size and binder, and strictly control grinding parameters including linear velocity, feed rate, cutting depth, and coolant flow rate. In practice, strategies such as slow feed grinding, forming grinding, or high-speed deep cutting grinding are often used to significantly improve metal removal rates and shorten single piece processing cycles while ensuring surface roughness Ra ≤ 0.4 μ m and contour accuracy ± 5 μ m.

Our heavy-duty forging presses support open-die forging and deformation of large-section forgings, including discs, shafts, blocks, and custom components. This capability enables us to meet the demanding forming requirements of heavy industrial applications.
Heat treatment is a critical step in achieving the mechanical properties required for heavy-duty forgings. Our process capabilities meet the strength, toughness, and structural stability requirements for forged components used under demanding operating conditions.
We offer machining capabilities for large forged shafts and long cylindrical components, supporting both rough and finish machining. This capacity is suitable for stepped shafts, rotor shafts, rollers, and other heavy-duty forged shaft components.
Our machining facilities are capable of handling large ring-shaped forgings and circular parts that require precise turning, face machining, boring, and contour control. This capability is suitable for industrial ring blanks, heavy-duty circular parts, and machined ring forgings.
We offer machining solutions for heavy-duty cylindrical, hollow, and tubular forgings. This capability supports the machining of sleeves, cylinders, and other thick-walled forged components used in pressure vessels, rotating systems, and general industrial applications.
Quality control is integrated into our production process through the inspection and testing of forged and machined parts. Our capabilities help verify the dimensional accuracy, condition, and quality consistency of industrial forgings prior to delivery.
Finished forgings are properly protected and packaged to minimize the risk of damage during storage and transportation. Our packaging methods ensure the safe domestic delivery and export shipment of machined and high-value forged components.
