Custom CNC Turned Milled 6061 Aluminum Cylinder Featuring Seal Grooves
Product Overview
The OEM Grooved Stepped Cylinder is a CNC turned and milled cylindrical body built for guided fit and sealing duty. External stepped diameters and multiple seal grooves are turned for concentricity, while a through bore with an internal step carries the mating component. Radial cross-holes are milled in controlled setups so their position holds true to the turned datum. Machined from 6061 aluminum, the part combines a high strength-to-weight ratio with good corrosion resistance and clean machined surfaces. The thin-wall open end is produced with light-pass strategies and supported fixturing to control deflection. Groove count, groove dimensions, bore geometry and hole positions are produced to your drawing, with inspection reports available on request.

Manufacturing Capability
·Turn and Mill in Controlled Setups — Stepped diameters, grooves and bores turned for concentricity; cross-holes milled in setups that hold their position to the turned datum.
·Thin-Wall Control — Light-pass strategies and supported fixturing control deflection on thin-wall sections and long slender bodies.
·Seal Groove Accuracy — Groove width and depth produced to drawing so seals seat correctly and hold pressure.
·Bore Accuracy — Through bores and internal steps finished for consistent mating fit and concentricity.
·Production Scalability — From single-piece prototypes to small-batch and high-volume production on the same line and the same tolerance standard.
Quality Control
·Three-Stage Inspection — First-article, in-process and final inspection performed on every order; dimensional reports issued with each shipment.
·Tooth Form Verification — Tooth form and keyway geometry checked against drawing tolerances; inspection results available on request.
·Runout Checks — Bore-to-pitch-circle runout verified to keep the gear running concentric on the shaft.
·Material Traceability — Mill certificates for 321 stainless steel available on request.
·Protective Packaging — Individual wrapping and partition packaging keep tooth flanks and edges free of transit damage.
Buyer Benefits
·Faster Time to Market — Same-day quotes and 3-7 day prototype delivery compress your development cycle.
·Lower Total Cost — Free DFM feedback flags thin webs, deep keyways and tight tooth tolerances before machining, eliminating costly rework.
·Dependable Quality — ±0.01 mm standard tolerance with tooth-form and runout verification on every shipment.
·Positive Torque Transfer — Keyed bore hub drives the shaft without slip and holds alignment through load cycles.
·Heat and Corrosion Resistance — 321 stainless steel resists oxidation and intergranular corrosion in demanding service conditions.
·Single-Point Accountability — One factory controls turning, hobbing, milling, EDM and inspection, so one call resolves any issue.
