Product Description
Electrogalvanizing Hexagonal Lock Nut Stainless Steel Screws And Nuts With Through Hole
The stainless steel hexagonal nut with through-hole adjustable screw. It is precisely processed by CNC.
Precision Instruments & Optical Equipment Applications
Practical Applications
- Microscope adjusting nuts
- Projector/lens fixing nuts
- Testing instrument locking nuts
- Laboratory precision platform assembly nuts
CNC Production & Processing Features
- Extremely high requirements for concentricity, flatness and perpendicularity (tolerance ≤ ±0.005 mm)
- Strict control over concentricity between internal threads and external contours
- Multi-reference surfaces and internal threads processed in single CNC clamping setup
- Fine-adjustment internal threads and limit slots for precision instrument requirements
- Materials include stainless steel and aluminum alloy with precision grinding
- Accurate positioning and reliable locking, preventing instrument accuracy degradation
- No displacement or shaking in precision-sensitive optical systems
- Smooth and consistent adjustment without jamming for high-precision requirements
Common CNC Machining Issues & Solutions
Accuracy Deviation Issues
- Repeated clamping causes out-of-tolerance concentricity and flatness
- High-precision fixtures and single-setup processing required
- Real-time dimensional monitoring to avoid thermal deformation deviations
Fine-Adjustment Thread Machining
- Precise lead control for internal threads in fine-adjustment nuts
- Strict control of thread machining accuracy with special taps
- Post-machining lead inspection for consistent adjustment feel
Surface Precision Grinding
- High-precision grinding machines with controlled speed and feed rate
- Surface roughness Ra ≤ 0.8 μm requirements
- Finishing after tapping to remove thread burrs
Limit Structure Machining
- Precise machining of limit slots to match instrument internal structure
- Travel testing after machining to avoid limit failure
- Ensures instrument adjustment accuracy
