What Is CNC Milling?
CNC milling is a way to cut metal and plastic into exact shapes. A computer controls spinning tools that remove material from a solid block. This makes your part match your design file perfectly. It's one of the most common ways to make custom parts. Hayward teams use our CNC milling for brackets, enclosures, housings, and custom fixtures.
We Fixture Your Blank
A block of metal or plastic is clamped onto the mill table in a vise or custom fixture.
Spinning Cutters Remove Material
Tools move along X, Y, and Z axes to carve pockets, slots, and surfaces layer by layer.
Your Part Comes Off the Table
We deburr, inspect, and measure every feature before shipping.
Built for Milling Projects
From simple brackets to complex 5-axis contours — one shop handles it all with precision and speed.
Multi-Axis Expertise
We handle simple 3-axis brackets and complex 5-axis sculpted parts on the same floor. Undercuts, compound angles, and deep pockets — no problem.
CMM Inspection
Every critical dimension is verified before shipping. Your receiving team gets a documented inspection report — no guessing, no shortcuts.
Material Versatility
Aluminum, stainless steel, titanium, brass, copper, Delrin, PEEK, nylon, and polycarbonate. Over 30 materials in stock and ready to mill.
Fast Turnaround
Upload your file and get a response fast. Most milled parts ship in 5–10 days. Rush orders in as few as 3 days. We communicate directly — no layers of sales reps.
From Simple Brackets to Complex 5-Axis Parts
Deep pockets, thin walls, and compound angles. We take on what others won't.
In Hayward, medical device companies drive demand for cnc milling. Local teams working with BioMarin Pharmaceutical and Impax Laboratories (Amneal) rely on precision 3 to 5-axis milling with tight-tolerance pockets and complex contours.
Hayward also has a strong industrial equipment presence that drives demand for precision 3 to 5-axis milling with tight-tolerance pockets and complex contours. Teams at Hayward Industries and Ghirardelli Chocolate (food processing) use our services for critical components. Hayward is home to Hayward Industries — a major manufacturer of pool and industrial water treatment equipment with precision-machined pump housings, valve bodies, and filtration system components.
In Hayward, semiconductor companies drive demand for cnc milling. Local teams working with Samsung Austin Semiconductor and NXP Semiconductors rely on precision 3 to 5-axis milling with tight-tolerance pockets and complex contours.
Hayward also has a strong defense presence that drives demand for precision 3 to 5-axis milling with tight-tolerance pockets and complex contours. Teams at BAE Systems and Elbit Systems of America use our services for critical components. Austin's defense ecosystem blends technology and manufacturing — BAE Systems' Austin campus builds electronic warfare and intelligence systems, Elbit Systems of America operates locally, and a grow...
3-Axis Milling
Flat surfaces, pockets, slots, and drilled holes. Works great for brackets, mounting plates, enclosures, and any part with features on one side.
Most common4-Axis Milling
Parts that need cuts on multiple sides without removing them from the machine. Faster delivery and lower cost for angled or wrapped features.
Multi-side access5-Axis Milling
Complex curves, undercuts, and sculpted surfaces. Our 5-axis machines cut from almost any angle. Fewer setups, tighter tolerances.
±0.0005" capableLarge Format Milling
Parts up to 24" x 18" x 12". Oversized brackets, plates, and housings with the same precision as smaller parts.
Up to 24" travelMicro Milling
Fine features down to 0.005" with tight tolerances. Perfect for small medical devices, electronics, and intricate mechanical parts.
0.005" featuresHigh-Volume Production
From 1 prototype to 5,000+ production parts. Optimized toolpaths and fixturing keep quality consistent across every piece.

What Engineers Say About
Working With RivCut
Real reviews from real engineers. Every project matters — including yours in Hayward.
We went through two shops before finding RivCut. Night and day difference. Parts come in right. Communication is clear. They held ±0.002" on a titanium bracket that two other shops couldn’t get right.
Aerospace PartsThey caught a tolerance issue in our drawing before production started. That saved us a full revision cycle and three weeks of delays. You don’t find that kind of attention to detail at most shops.
Medical DeviceWe needed fast turnaround on 5-axis parts for a new enclosure. RivCut delivered in 6 days. Quality was excellent. These guys move fast without cutting corners.
