Equipped with a Siemens 828D CNC system and servo motor drive. The machine tool design thoroughly analyzes the technical performance indicators and innovative mechanical structure forms of roller grinding machines from Italy's ATOMAT and Germany's HERKULES companies, while also incorporating experience from similar machine tools of well-known domestic enterprises.
This series of machine tools is primarily used for the hole shaping of rolling mill rolls and can also turn the outer diameter and roll necks of rolling rolls. It is capable of machining similar roll components. Suitable for cutting cast steel, forged steel, alloy steel, chilled cast iron, nodular cast iron, tungsten carbide roll rings, and various other materials, it is ideal for processing large-scale rolling rolls such as special steel, reducing costs and enhancing efficiency.
The CK84100 CNC roller grinding machine features an integrated 4+1 guide rail structure, with four rectangular guide rails horizontally arranged on the bed body to provide motion and positioning for the saddle and tailstock, and an auxiliary guide rail is set on the vertical front surface of the bed body to support the saddle. This ensures improved rigidity for the saddle and tool holder, enabling them to handle greater cutting torques.
The bed基准guide rail is treated with integral ultra-audio quenching, paired with imported guide rail soft strips, ensuring minimal wear and movement of all feeding components, maintaining high precision and stability over the long term. A certain height difference is designed between the saddle guide rail and the tailstock guide rail to prevent chips and coolant from entering the saddle guide rail.
The tailstock features an independent rotating main shaft + sleeve axial extension and adjustment structure. The tailstock main shaft cone hole is 100-1:5. The tailstock body is designed with an integral structure, eliminating the drawbacks of traditional upper and lower split structures, such as unstable precision, poor load-bearing capacity, and reliability issues.
The lathe tailstock is equipped with a high-performance pressure sensor for the setting and measurement of the clamping force during workpiece mounting on the lathe, as well as feedback. The pressure sensor controller can be set and adjusted to automatically control and display the clamping force of the tailstock point on the workpiece. The release and clamping of the tailstock sleeve are automatically achieved through the hydraulic control system.
The tailstock sleeve is designed with a thermal deformation compensation mechanism for workpieces. During the machine tool's operation, the axial length changes of the workpiece are absorbed and compensated by the conical spring inside the sleeve.
