Connecting Sleeve/Sensor Housing CNC Machining For Precision Instruments & Automation Equipment
Custom CNC Machining — From Your Drawing to Finished Parts
This Connecting Sleeve / Sensor Housing is a core structural and precision-mounting component designed for precision instruments, automation equipment, sensor mounting assemblies, and high-accuracy positioning systems. It is manufactured by our in-house CNC Machining (50 Lathe + 4-Axis Machining Center) process from 7075 aluminum alloy with T6 solution heat treatment to achieve high strength, precise concentric geometry, and reliable dimensional stability under operational loads. The use of 7075-T6 aluminum provides an excellent balance of tensile strength comparable to mild steel, superior fatigue resistance under cyclic loading, and excellent machinability for fine tolerances.
Matech's one-stop approach, covering raw material sourcing with mill certificates, CNC turning and 4-axis machining center operations (internal bore, external profile, mounting threads, sensor window features), T6 solution heat treatment, bead blasting + matte natural anodizing surface treatment, concentricity and dimensional inspection, and engineered packing, ensures this connecting sleeve offers excellent concentricity accuracy, tight dimensional tolerances on bore and mounting interfaces, and a ready-to-install finish — performing reliably in demanding precision instrument and automation applications.

Our Advantages
Technical Advantages
Raw material warehousing, CNC turning & 4-axis machining centers, heat treatment, surface treatment, and inspection lab — all centralized under one roof. No subcontracting for any process step. From certified bar stock to finished and anodized part, we maintain full control over lead time, multi-process sequencing, and final quality.
Before the first chip is cut, our engineering team reviews your drawing for machining feasibility. We provide feedback on concentricity requirements, tolerance stack-ups, thread specifications, and suggestions to optimize internal bore-to-external profile alignment. Combined with in-house CAM programming for 50 lathe and 4-axis machining centers, we ensure efficient toolpaths and consistent concentricity from first article to production batch.
We specialize in high-precision cylindrical and housing components — such as sensor housings, connecting sleeves, precision bushings, and mounting adapters. Our 50 lathe and 4-axis machining center capabilities deliver fine surface finishes (Ra 0.8µm and below on mating surfaces), tight concentricity tolerances (within 0.02mm), and precise thread quality verified by thread gauges. We are experienced with 7075-T6, 6061-T6, 316 stainless, and other high-performance alloys.
Service Advantages-总部接待区 1 拷贝
Material Advantages
All 7075 aluminum bar stock is sourced from certified mills. Every piece of material arrives with mill test certificates (EN 10204 3.1) stating heat number, chemical composition, and mechanical properties. We verify incoming material against these certificates before it enters production — no unverified material ever reaches your part.
Material batch integrity is maintained from raw stock to finished part. We tag and segregate material by heat/lot number through sawing, machining, heat treatment, and anodizing stages. We deliver a complete traceable dossier — mill cert, T6 heat treatment record, anodizing thickness report, concentricity inspection data, and final dimensional report — all linked to the original material lot.
We machine a wide spectrum of engineering materials — aluminum alloys (7075-T6, 6061-T6), stainless steels (304/316/17-4PH), carbon & alloy steels (45#, 40Cr, 4140), titanium, and engineering plastics (POM, PEEK, PTFE). Your material specification, whether a standard grade or a niche alloy, is well within our experience.
Service Advantages
A dedicated project manager oversees the entire process — from design review to final delivery — ensuring efficient communication at every stage and a single point of contact for all technical and commercial matters.
Quotations are typically provided within 24–48 hours. Production progress is updated regularly through photos and production data, with continuous customer feedback collection throughout the project. For precision concentric components, first-article inspection reports including concentricity measurement and surface finish verification are provided before batch production begins.
Full batch traceability and 24-hour response to quality-related issues ensure reliable post-delivery support. Flexible MOQ with pilot order options available for new machining projects.
