Description
Female Union Tee is a brass union tee product designed specifically for piping systems, characterized by all interfaces being female threads. This design not only facilitates direct fitting with external thread (male thread) fittings, but also enables easy disassembly and installation, making it suitable for occasions that require regular maintenance, inspection, or replacement of pipelines.
CNC is a technology that uses computer programming to control machine tools for precision machining. Its core is digital instructions to drive mechanical motion, replacing traditional manual operations.
Working principle of CNC:
Programming process:
CAD modeling: Design 3D models using software such as SolidWorks and AutoCAD.
CAM programming: Generate tool paths (such as Mastercam) and output G-code.
Post processing: Convert generic code into machine specific instructions (adapted to different controllers).
Processing process:
Tool alignment: Set the workpiece coordinate system.
Automatic processing:
Main spindle speed control (S command, such as S5000 representing 5000 revolutions per minute).
Feed axis: XYZ axis linkage (F command controls feed speed).
Real time monitoring, detecting tool wear, temperature and other parameters through sensors.

Main application areas of CNC:
(1) High end manufacturing
Aerospace: turbine blades (5-axis machining), fuselage structural components.
Automotive industry: engine cylinder block, mold (surface roughness Ra0.8 μ m).
(2) Precision components
Medical equipment: artificial joints (titanium alloy processing), surgical instruments.
Electronics industry: mobile phone casings (high-speed milling), chip packaging molds.
(3) Personalized customization
Artwork: relief carving (with a small tool diameter of 0.1mm).
Mold development: injection molds, die-casting molds (hardness HRC50 or above).
