Burner caps (gas stove burner covers) are typically made of materials such as cast iron, stainless steel, or copper alloys, which have high hardness and heat resistance. Therefore, in CNC drilling, an appropriate solution is required to ensure machining accuracy and efficiency. Below are common CNC drilling solutions for burner caps:
1. Equipment Selection
CNC Drilling & Tapping Machine
Suitable for high-precision, multi-hole drilling with automated operation.
Improves production efficiency and ensures consistent quality.
Recommended equipment: DUOMI CNC drilling & tapping machines (e.g., XD series).
Laser Drilling Machine
Ideal for high-hardness materials and precision micro-hole processing.
Offers superior accuracy but comes at a higher cost.
High-Speed Drilling & Milling Center
Suitable for complex-shaped burner caps, enabling both drilling and post-processing, such as milling cooling grooves.
2. Tool Selection
Carbide Drill Bits (For cast iron, stainless steel, and copper alloys)
TiAlN-coated for enhanced wear resistance.
Coolant usage recommended to prevent overheating and extend tool life.
PCD (Polycrystalline Diamond) Drill Bits (For high-hardness materials)
Ideal for mass production, offering extended tool life but at a higher cost.
High-Precision Micro Drills (For small-hole drilling, e.g., diameters below 0.5mm)
Ensures fine detail and accuracy in micro-drilling applications.
3. Machining Process
Positioning & Fixture Design
Uses customized fixtures to ensure consistency for each burner cap.
Vacuum suction or special clamping systems prevent workpiece displacement.
Drilling Parameters (Example: Cast Iron Burner Cap)
Spindle speed: 8,000 - 15,000 RPM (adjustable based on material).
Feed rate: 100 - 500 mm/min.
Drilling method: Step drilling or high-pressure coolant drilling.
Deburring & Post-Processing
Deburring tools, sandblasting, ultrasonic cleaning, etc., ensure smooth hole edges.
4. Automation & Smart Manufacturing
Automated loading & unloading systems enhance production efficiency.
Vision inspection systems ensure precise hole positioning and diameter accuracy.
MES (Manufacturing Execution System) integration allows for real-time monitoring and production management.
