Numerical control gear hobbing machine is a metal cutting machine tool that combines numerical control technology and inclined rail design, mainly used for machining 

various internal and external spur and helical cylindrical gears as well as other tooth shaped parts. It controls the relative motion between the tool and the workpiece through advanced numerical control systems,

Realize high-precision gear machining. Its inclined rail design enables the machine tool to adjust the position of the tool and workpiece more flexibly during the machining process, thereby meeting the machining needs of various complex gears.

The working principle of the CNC inclined rail hobbing machine is based on the hobbing method, which uses a hobbing tool as a cutting tool to cut the workpiece according to a predetermined trajectory. 

During the machining process, the gear hobbing tool performs a reciprocating cutting motion up and down,

Simultaneously perform rolling and oblique feed movements relative to the workpiece. By controlling the relative position and speed of the tool and workpiece through a numerical control system, 

high-precision gear machining can be achieved.

Operation steps of CNC gear hobbing machine:

1. Preparation work

Choose appropriate cutting tools and cutting fluids: Based on the gear parameters, materials, and requirements of the workpiece to be machined, select the appropriate gear hobbing tool and cutting fluid.

Conduct safety checks: Ensure that all components of the gear hobbing machine are complete, securely installed, and the circuit is normal. Check for any oil or electrical leakage in the equipment.

Clean the surface of the processed workpiece: Ensure that the workpiece surface is flat, clean, and free of debris to avoid affecting the machining accuracy.

2. Operation steps

Fixed machining workpiece: Fix the machining workpiece on the fixture and adjust the angle to ensure that the workpiece does not bounce or shake during the machining process.

Choose a gear hobbing tool: Select a suitable gear hobbing tool based on the gear parameters of the workpiece being processed, and install the gear hobbing tool onto the tool holder.

Equipment cutting fluid: Inject suitable cutting fluid into the gap between the workpiece and the gear hobbing tool to reduce cutting temperature and improve cutting accuracy.

Set processing parameters: Set processing depth, speed, and feed rate parameters according to processing requirements to ensure processing efficiency and quality.

Start the gear hobbing machine: Place the workpiece under the tool, press the start button to start machining, and closely monitor the machining status during the process.

Check machining quality: Observe machining quality in a timely manner during the machining process, adjust machining parameters or equipment settings in a timely manner if problems are found.

3. Precautions

Ensure safety status: Ensure that the gear hobbing machine is in a safe state before operation, and wear protective measures such as goggles and gloves during processing.

Strictly follow the process: Do not change the operation process arbitrarily to avoid equipment failure or personal safety accidents caused by improper operation.

Choosing appropriate tools and accessories: Using suitable tools and accessories can improve machining quality and equipment lifespan, while also paying attention to regularly replacing worn tools.

Timely cleaning and maintenance: After processing, thoroughly clean the machine, tools, and cutting fluid, keep the equipment clean, and replace faulty parts in a timely manner.
