Dongguan Changxinda Precision Technology Co., Ltd. specializes in CNC precision machining of aluminum 7075 optical adapter rings for measurement instruments and optical equipment. Manufactured using advanced 4-axis and 5-axis CNC milling centers, these precision adapter rings deliver the dimensional accuracy and surface flatness demanded by modern optical and measurement systems. The ring-shaped design with center through-hole and multiple mounting holes makes them ideal for lens mounting applications where precise alignment and stable positioning are essential.
The aluminum 7075 alloy offers exceptional strength-to-weight ratio, excellent mechanical stability, and superior dimensional stability under varying environmental conditions. With high tensile strength and good fatigue resistance, aluminum 7075 provides the rigidity needed for optical systems to maintain precise alignment during operation. The material also exhibits excellent machinability, allowing Changxinda to produce adapter rings with ultra-flat end faces and precisely positioned mounting holes required for accurate optical performance.
Precision is fundamental to optical adapter ring performance. Changxinda's CNC milling operations achieve tolerances of +/-0.01 mm on critical dimensions, ensuring consistent optical alignment across production batches. End face flatness is controlled to extremely strict standards, typically achieving flatness within 0.01-0.02 mm across the mounting surface. This level of flatness is critical for optical systems where any deviation can cause focal plane distortion, image quality degradation, or measurement errors in precision instruments.
The center through-hole design accommodates light transmission and lens mounting, while the multiple mounting holes around the circumference provide secure attachment to optical assemblies. These mounting holes are precision machined to exact positions and sizes, ensuring that the adapter ring aligns correctly with corresponding optical components. The surface finish is controlled to high standards, with machined surfaces exhibiting smooth, uniform textures that minimize light scattering and ensure secure lens seating.
Production flexibility is a key advantage. Changxinda supports the full production lifecycle from prototype development to mass production. Quick-turn prototyping enables rapid design validation and optical testing, while scalable production capacity accommodates batch orders ranging from small series to large quantities. Each optical adapter ring undergoes rigorous in-process inspection and final quality verification using coordinate measuring machines, optical flatness measurement equipment, and precision gauges, with statistical process control applied to critical dimensions.
Dongguan Changxinda Precision Technology Co., Ltd. is ISO 9001:2015 certified and committed to delivering precision machined components that meet the highest industry standards. With a team of more than 30 experienced professionals and comprehensive 4-axis/5-axis CNC machining capabilities, the company provides fast delivery, responsive communication, and reliable quality that has resulted in many successful cooperation cases with satisfied customers worldwide. Whether you need prototype quantities or large-scale production, Changxinda delivers CNC precision machining excellence tailored to your optical adapter ring requirements.
Q1: What materials are available for optical adapter rings?
A: Aluminum 7075 is our standard recommendation for its excellent strength-to-weight ratio and dimensional stability. We also work with aluminum 6061, brass, and other materials based on customer requirements.
Q2: What flatness tolerance can you achieve?
A: Our CNC machining achieves flatness within 0.01-0.02 mm on end faces. We can discuss tighter flatness requirements for specific applications based on your optical system needs.
Q3: What is the typical lead time?
A: Lead time depends on order complexity and quantity. Prototypes typically take 2-3 weeks, while production orders range from 4-8 weeks depending on batch size and specifications.
Q4: Do you provide design support?
A: Yes, our engineering team offers design for manufacturability (DFM) feedback, optical alignment consultation, and process optimization recommendations to help improve your product performance.
Q5: What surface treatments are available?
A: We offer various surface treatments including anodizing (Type I, II, III), powder coating, and custom finishes. Anodizing is commonly used for optical adapter rings to provide corrosion resistance and improved wear properties.
Q6: Can you handle both small and large production orders?
A: Yes, we support the full production range from prototype quantities (5-20 pieces) to small batches (20-100 pieces) and mass production (100-10,000+ pieces). Our flexible production capacity accommodates various order sizes.
Q7: What quality documentation do you provide?
A: We provide material certificates, dimensional inspection reports, flatness measurement reports, first-article inspection reports, and other quality documentation as required by your quality system.
Q8: What measurement equipment do you use for inspection?
A: We use coordinate measuring machines (CMM), optical flatness measurement equipment, precision gauges, and surface roughness testers to verify dimensional accuracy and surface quality of optical adapter rings.
Q9: How do you ensure consistent optical performance across batches?
A: We implement statistical process control (SPC) on critical dimensions, conduct in-process inspections, and perform final CMM verification. Optical flatness measurements ensure consistent alignment performance.
Q10: What industries do you serve?
A: We serve optical equipment, measurement instruments, medical devices, semiconductor, aerospace, laser, automation, and many other industries requiring precision machined optical components.
