Friction stir welding (FSW) joins aluminum components in the solid state, avoiding the melting, porosity, and distortion common in fusion welding. At XY-Global, FSW is performed in-house alongside CNC machining, allowing sealed aluminum enclosures and housings to be welded and finish-machined in a single controlled workflow. This article explains how FSW works, which aluminum grades and joint types it suits, and how combining it with CNC machining improves dimensional stability for sealed, high-integrity parts.

Titanium offers a combination of properties — high strength-to-weight ratio, low thermal expansion, excellent corrosion resistance, and biocompatibility — that makes it the material of choice for demanding applications in medical devices, aerospace systems, optical instruments, and precision industrial equipment. However, those same properties make titanium significantly more difficult to machine than aluminum or steel. Achieving tight tolerances and good surface finish on titanium requires specific tooling, cutting strategies, coolant management, and process knowledge that differ substantially from standard CNC machining practice. This article explains what precision titanium CNC machining involves, why titanium presents unique process challenges, which alloys are most commonly used, and what to look for in a machining supplier for titanium components.

Sourcing a custom lens barrel manufacturer is not the same as buying a standard optical component off a catalog page. Custom lens barrels must meet a specific combination of bore diameter, thread form, surface finish, material, and surface treatment requirements that vary by application — and the manufacturer's ability to interpret a drawing, raise DFM issues early, and hold tight tolerances consistently across a production run determines whether the project succeeds. This article explains what to look for in a custom lens barrel manufacturer, how the custom production process typically works, and what to evaluate before placing an order.
