Sensor Components  Manufacturers, Traders, Suppliers

CNC-machined sensor components require high precision and dimensional stability to ensure accurate sensing and reliable performance. These parts often feature complex geometries and tight tolerances, with materials like aluminum, stainless steel, or titanium chosen for their thermal stability, corrosion resistance, and strength. Sensor components are critical in industries such as automotive, aerospace, medical devices, and industrial automation, where miniaturization and surface finish quality are also key considerations.

1. Material Selection
Aluminum (e.g., 6061, 7075): Lightweight, excellent machinability, and good thermal conductivity.
Stainless Steel (e.g., 304, 316): High strength, corrosion resistance, and durability.
Titanium (e.g., Grade 2, Grade 5): High strength-to-weight ratio and corrosion resistance.
Plastics (e.g., PEEK, Delrin): Electrical insulation and lightweight, suitable for non-conductive applications.
Copper Alloys (e.g., C11000): Excellent electrical and thermal conductivity.
2. Machining Challenges
High Precision: Sensor components often require tolerances within ±0.01 mm.
Complex Geometries: Intricate designs with thin walls, small features, and tight clearances.
Surface Finish: Smooth finishes (Ra < 0.8 µm) are often required for functional and aesthetic purposes.
Material-Specific Issues:
Aluminum: Soft and prone to burrs.
Stainless Steel: Hard and abrasive, leading to tool wear.
Titanium: Low thermal conductivity, causing heat buildup.
Plastics: Low melting point and prone to deformation.
3. Tool Selection
Tool Material: Carbide or diamond-coated tools for durability and precision.
Tool Geometry: Sharp cutting edges and polished surfaces to reduce cutting forces and improve finish.
Coolant: Use water-soluble coolants or air blast for effective heat dissipation.
4. Cutting Parameters
Cutting Speed (Vc):
Aluminum: 200-500 m/min
Stainless Steel: 50-150 m/min
Titanium: 30-80 m/min
Plastics: 300-600 m/min
Feed Rate (f): 0.02-0.1 mm/tooth (lower for finer finishes).
Depth of Cut (ap): 0.5-2 mm (adjust based on material and tool rigidity).
Coolant: Essential to prevent overheating and improve tool life.
5. Surface Finish
Typical Ra Value: < 0.8 µm (often < 0.4 µm for functional surfaces).
Post-Processing: Polishing, anodizing (for aluminum), or coating for improved performance and aesthetics.
