high speed CNC gear hobbing machine
- Product Details
- Company Profile
machine adopts the principle of generating method, and through the function of the electronic gearbox of the numerical control system(EGB), which is mainly used for machining all kinds of high precision spur gears, helical gears and turbines,drum gears, splines, etc. The machine tool has strong overall steel and stable precision, and can be used for high-speed dry cutting, high-speed wet cutting and hard tooth surface machining. It has widely used in cars, motor rate, motorcycle, motor reducer, hydraulic mercury and other industries of gear processing
?Machine tool bed is a high rigid cast iron base, with double wall structure, the overall rigidity is stronger, and the accuracy is more stable; ?Spindle (B axis) servo motor directly connected tool holder design, with locking mechanism tool holder, the overall rigidity is stronger; ?The work shaft (C axis) is directly driven by DD motor, which avoids the error caused by transmission and improves the accuracy and stability of the machine tool; ?The tool holder adopts balanced cylinder and motor-starting drive, which improves the stability of tool feed; ?With the secondary interface of special human-computer interaction, the operator is easy to learn and easy to use; ?Automatic tool channeling function: set reasonable parameters, realize fixed length and quantitative automatic tool channeling in the machining process, make the tool wear evenly and improve the tool durability; ?Fast fallback tool protection function: when the fault occurs in machining, the back key is clapped in time or the power is suddenly cut off, the work piece is synchronized with the tool and the tool is withdrawn to protect the tool from collision damage quickly; ?Secondary tool cutting device: gear rough rolling, secondary finishing after heat treatment, suitable for cutting hardness HRC57 soil 2 °hard tooth surface machining (optional);?The circulating oil is cooled quantitatively to ensure that the machine tools, gears and fixtures have good cutting ability and precision stability, and the machiningaccuracy can reach grade 6 of GB/T 10095.1 / 2008. the tooth surface roughness is Ra1.6μm.
