The CNC gear hobbing machine adopts advanced CNC systems and servo motors to control circumferential and radial feed, suitable for large-scale rough and precision machining in professional factories such as automobiles, motorcycles, machine tools, and gears. It is particularly suitable for internal and external cylindrical gears, double and multiple gears, sector gears, intermittent gears, and pre modified gears with a taper within ± 30 °. Special attachments can be added to CNC gear hobbing machines, which can also process helical gears, shaft gears, bevel gears, drum gears, etc. It is easy to operate and has low dependence on manual technology.

Machine characteristics of CNC gear hobbing machine:

1. Machine tools have good rigidity, strong vibration resistance, and high dynamic accuracy

This machine tool adopts the popular column feed method, and the high inertia column feed can ensure higher rigidity of the machine tool compared to the small inertia workbench feed. The main components of the machine tool, such as the bed, column, and tool holder, are made of high-quality gray cast iron, with suitable wall thickness, reasonable rib layout, and sufficient overall quality, greatly improving the stiffness and vibration resistance of the machine tool, ultimately ensuring high dynamic accuracy of the machine tool.

2. Machine tools have high work efficiency and good accuracy retention

The main moving component of the machine tool - the tool holder component adopts self-developed and obtained the national ZHUAN LI static pressure guide rail and static bearing, making the machine tool have high speed, high precision, and high stability; The spindle and other components have the characteristics of no wear, long service life, and good accuracy retention, and have the level of domestic LING XIAN technology.

3. The transmission accuracy of machine tools is high, and the working accuracy is good.

The transmission chain of the machine tool is simple, and all main movements are directly connected to the motor for transmission. The radial feed motion adopts precision ball screw transmission, which has high positioning accuracy and repeated positioning accuracy; The rotary motion of the workbench and cutter shaft adopts high-precision worm and worm gear transmission, with high indexing accuracy and smooth operation; The machine tool guide rail adopts the current XIN wear-resistant coating technology, which has good friction performance, eliminates the crawling phenomenon of the guide rail at low speeds, and provides appropriate damping for the system. It is a new structure currently used in CNC gear hobbing machines.

4. Comprehensive protection considerations, convenient operation and maintenance

This machine tool is a vertical vertical layout structure, equipped with a separate electrical cabinet (using a layout structure with an operating table attached to the side of the electrical cabinet, effectively improving the space utilization of the machine tool), a hydraulic station, a lubrication station, and a magnetic chip conveyor. The machine tool structure layout is reasonable, the work area is protected and safe, the operation is convenient, and the maintenance is simple. When designing machine tools, the principles of ergonomics are utilized to meet the performance requirements of the machine tool while fully considering factors such as the operator's work habits and fatigue limits, so that the operator can work in a safe and comfortable environment as much as possible. At the same time, the control system of the machine tool also has strong protection functions, and it will immediately stop and alarm in case of faults such as overtravel, overload, loss of pressure, or other faults, ensuring the safety of the machine tool.
