Medical Device Manufacturing ในประเทศไทยโต 8-10% ต่อปี (ตาม industry reports) — ต้องการ precision machining + surface finishing ตามมาตรฐาน ISO 13485 และ FDA 21 CFR Part 820 · U-Bright Machine (YK7326 Grinding, SKS20 Straightener, CNC Finishing) complement eldec Induction Hardening เป็น integrated supply chain — บทความนี้โฟกัสที่ precision machining/finishing (ไม่ใช่ hardening)
U-Bright Machine สำหรับ Medical Device Supply Chain
- YK7326 Precision Grinding Machine — Orthopedic implant, Bone screw thread, Dental implant
- SKS20 Motor Shaft Straightener — Surgical motor, Bone drill, Dental handpiece
- CNC Turning/Milling — Surgical instrument components
- Surface Grinder — Flat instrument parts (retractors, scalpels body)
- Cylindrical Grinder — Shaft, rod, pin
Orthopedic Implant Precision Grinding
| Implant Type | Material | Ra Target | U-Bright Machine |
|---|---|---|---|
| Hip Stem (femoral) | Ti-6Al-4V, CoCr-Mo | 0.2-0.4 µm | YK7326 Cylindrical |
| Hip Cup (acetabular) | Ti alloy + UHMWPE | 0.2 µm | Spherical grinder |
| Knee Femoral | CoCr-Mo | 0.2-0.4 µm | Profile grinder |
| Knee Tibial | Ti alloy + UHMWPE | 0.3-0.5 µm | Surface grinder |
| Spine Pedicle Screw | Ti-6Al-4V | 0.4 µm | Thread grinder |
| Bone Plate | Ti, 316LVM | 0.4-0.8 µm | Profile + Surface |
Why Ra 0.2-0.4 µm สำคัญสำหรับ Implant
Surgical Motor & Bone Drill Shaft Finishing
หลัง Induction Hardening แล้ว shaft ต้อง straighten + grind ให้ได้ concentricity ±0.002 mm:
- SKS20 Motor Shaft Straightener — 190-600 mm workpiece, ±0.01 mm straightness, servo-controlled, 2,000-3,000 pcs/day
- YK-series Cylindrical Grinding — Post-straighten finishing to Ra 0.2-0.4 µm
- Centerless Grinding — High-volume micro-shaft (Ø2-8 mm)
Applications: Surgical motor rotor shaft (20K-80K RPM), Bone drill, Dental handpiece shaft, Orthopedic power tool
Bone Screw Thread Grinding
- Pitch accuracy ±0.01 mm
- Thread profile Ra 0.4 µm
- Core diameter ±0.03 mm
- Head recess (Torx/Hex) ±0.05 mm
- Tip self-tapping edge sharp
- Material: Ti-6Al-4V, 316LVM, PEEK
