Operating Principle of a CNC Valve Grinding Machine

A CNC valve grinder is a type of CNC grinding equipment specifically designed for precision machining of engine valves, primarily used to repair or machine valve tapers, stems, and end faces. Its operating principles are as follows:

CNC System: Programmable control of the grinding wheel feed rate, speed, and workpiece rotation speed enables high-precision grinding.

Grinding Wheel Dressing System: Utilizes a diamond roller to automatically dress the grinding wheel, ensuring grinding accuracy and surface quality.

Automatic Tool Setting and Measurement: Equipped with high-precision sensors, it automatically detects valve dimensions and adjusts grinding parameters in real time.

Multi-Axis Motion: Utilizing X- and Z-axis linkage, it performs combined grinding of the valve taper and stem, ensuring angular and dimensional accuracy.

 

Operating Specifications of a CNC Valve Grinding Machine

Pre-processing Preparation: Check that the valve is securely clamped to prevent loosening during machining. Select the appropriate grinding wheel and cutting parameters based on the valve material (such as stainless steel or heat-resistant alloy). Program Setup: Enter machining parameters such as valve taper angle and stem diameter for simulation verification. Set appropriate grinding wheel speed, feed rate, and coolant flow rate.

Processing: Enable the automatic tool setting function to ensure accurate positioning of the grinding wheel and workpiece. Monitor the grinding status to prevent overheating or vibration from affecting machining quality.

 

Features and Advantages of CNC Valve Grinders

High-precision machining: Taper angle accuracy reaches ±0.1°, and surface roughness Ra ≤ 0.4μm, ensuring valve sealing.

High Automation: Supports automatic loading and unloading, tool setting, and sand dressing, reducing manual intervention.

Efficient and Stable: Utilizes CBN or diamond grinding wheels for high wear resistance, suitable for high-volume continuous machining.

Adaptable: Capable of machining steel, alloy, and titanium alloy valves, meeting the needs of automotive, motorcycle, and marine engines.

Intelligent Detection: Optional online measurement system monitors machining dimensions in real time and automatically compensates for errors.
