Precision equipment model customization manufacturer
1、 Project positioning and technical roadmap
This plan adopts a dual presentation method of "structural anatomy+dynamic demonstration" to reproduce a certain type of precision CNC machine tool at a scale of 1:25. Through modular disassembly design, the core components such as the spindle transmission system, guide rail feed mechanism, and tool magazine are highlighted, and basic actions such as spindle rotation and tool magazine tool change are synchronously simulated.
Core production indicators
Static restoration degree ≥ 92% (based on 3D scanning comparison)
Dynamic system failure rate<0.5 times/demonstration cycle
Interactive components account for over 40%
2、 Implement the process in stages
1. Precision casting stage
Metal skeleton forming: The brass base is cast using the lost wax method, and the flatness error is ensured to be ≤ 0.02mm through CNC precision milling
Application of composite materials:
Guide rail system: chrome plated aluminum oxide ceramic treatment
Protective cover: 0.5mm acrylic vacuum hot bending formed
Operation panel: UV printed imitation metal brushed texture
2. Mechanical transmission system
Micro harmonic reducer: 3D printed planetary gear set (module 0.3)
Linear module: self-made cross roller guide rail, matched with 0.15mm stainless steel ball holder
Pneumatic components: Integrated solenoid valve control with a Φ 2mm miniature cylinder
3. Surface finishing
Etching process: Chemical etching of nameplates and dials (minimum line width 0.1mm)
Multi layer spraying:
Primer: Epoxy resin conductive coating
Topcoat: two-component polyurethane matte paint
Protective layer: Nano scale oil repellent coating
3、 Dynamic System Integration
1. Electromechanical control system
Main control unit: STM32F407 core board
Sensor network:
Hall element detects spindle speed
Micro photoelectric switch positioning knife magazine
Strain gauge monitoring cutting simulation load
2. Human computer interaction design
7-inch capacitive touch screen embedded in console
Tri color LED working condition indicator light group
Physical emergency stop button (with self-locking function)
