Used VIGERT YHK31125 CNC Gear Hobbing Machine For Sale

The YHK31125 CNC Gear Hobbing Machine is a highly specialized and precision machine tool designed for the manufacturing of gears. Gear hobbing is a cutting process used to create teeth on cylindrical workpieces, and this CNC machine automates and enhances the accuracy of this process. Here’s a detailed description of the YHK31125 CNC Gear Hobbing Machine:

1. Machine Bed and Base: YHK31125 CNC Gear Hobbing Machine. The machine features a robust and rigid bed or base, typically made of high-quality cast iron or steel. This construction provides stability and minimizes vibrations during the gear hobbing process, ensuring high precision.
2. Tool Spindle: The tool spindle is responsible for holding and rotating the gear hobbing cutter. It can rotate at different speeds and is driven by a powerful motor. The spindle speed is controlled by the CNC system to achieve precise gear cutting.
3. Workpiece Holding: The machine includes a workholding mechanism, often a chuck or fixture, that securely holds the workpiece in place. The workpiece rotates on its axis, and the cutter engages with it to cut the gear teeth.
4. Hobbing Cutter: The hobbing cutter is a specialized tool with multiple cutting edges or teeth designed to generate the gear teeth profile. These cutters come in various shapes and sizes to produce different gear types and sizes.
5. CNC Control System: The heart of the machine is its computer numerical control (CNC) system. The CNC system interprets G-code instructions and precisely controls the tool spindle’s rotation, workpiece movement, and feed rates. It also manages the indexing of the workpiece to produce the desired gear profile.
6. Automatic Tool Changer: Many CNC gear hobbing machines are equipped with automatic tool changers that can hold multiple hobbing cutters. This allows for the production of gears with different profiles without manual tool changes.
7. Axis Movements: The YHK31125 typically has multiple axes of movement, including X, Y, Z, and possibly additional rotary axes. These movements control the tool’s position and orientation, enabling the precise cutting of gear teeth.
8. Coolant System: YHK31125 CNC Gear Hobbing Machine. A coolant system is employed to dissipate heat generated during the hobbing process and to remove metal chips. The coolant helps extend the life of the hobbing cutter and improves surface finish.
