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 of roller grinding machines from Italy's ATOMAT and Germany's HERKULES companies, while also incorporating experience from similar machine tools of renowned domestic enterprises.
This series of machine tools is primarily used for the processing of roller profiles, and can also turn the outer diameter and roller necks of rollers. It is capable of machining similar roller components. Suitable for cutting materials such as cast steel, forged steel, alloy steel, chilled cast iron, nodular cast iron, and tungsten carbide roller rings. It is ideal for processing large-scale rollers like special steel, reducing costs and improving efficiency.
The CK84100 CNC roller grinding machine features an integrated 4+1 guideway structure. This means that the bed is horizontally arranged with four rectangular guideways, which separately provide movement and positioning for the saddle and tailstock. Additionally, an auxiliary guideway is set on the vertical face of the bed's front side to support the saddle. This design ensures better rigidity for the saddle and tool holder, enabling them to handle greater cutting torques.
The bed base guide rail is heat treated with integral ultra-audio frequency, combined with imported guide rail soft strips to ensure minimal wear and tear of feeding components, maintaining high precision and stability over the long term. The design features a certain height difference 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 and a sleeve axial extension adjustment structure. The tailstock main shaft has a cone bore of 100-1:5. The tailstock body is designed with an integrated structure, eliminating the disadvantages 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, which is used for setting and measuring the clamping force of the tailstock during the clamping of workpieces on the lathe, as well as for feedback. By adjusting the pressure sensor controller, the clamping force of the tailstock point on the workpiece can be automatically controlled and displayed. The release and clamping of the tailstock sleeve are automatically achieved through the hydraulic control system.
The tailstock sleeve is designed with a workpiece thermal deformation compensation mechanism. The axial length changes of the workpiece during the machine tool's operation are absorbed and compensated by the conical spring inside the sleeve.
