CNC Machining for OEMs and Manufacturers That Need Reliable Production Support
We work with OEMs, equipment manufacturers, and product companies that rely on outsourced CNC machining for ongoing production.
Our customers value consistent quality, responsive communication, and a manufacturing partner who can reliably support production — not simply a shop that machines parts to print.
When specifications change or production issues come up, we work with your team to resolve manufacturing details and help keep production moving with consistent quality from order to order.
One Reliable Source for CNC Production Parts
Mastro helps manage the manufacturing side of your CNC production parts, not just the machining itself.
We coordinate CNC machining, secondary processes, heat treatment, surface finishing, and inspection through one point of contact, helping reduce handoff issues and simplify overseas sourcing.
Our goal is to provide a dependable manufacturing source that can maintain quality, communication, and production consistency across repeat orders.
Core CNC Machining Capabilities

CNC Turning & Mill-Turn Machining
✓ Tolerance as tight as ±0.01 mm
✓ Precision turned and mill-turn components with milled flats, slots, cross holes, threaded features, and more
✓ Consistent dimensions and quality across repeat production runs
✓ Aluminum, stainless steel, steel, brass, titanium, and engineering plastics

CNC Milling & 5-Axis Machining
✓ Tolerance as tight as ±0.02 mm
✓ 3-axis, 4-axis, and 5-axis CNC milling for precision production parts
✓ Suitable for multi-sided parts, contoured surfaces, and reduced setup requirements
✓ Consistent machining quality for repeat production
Production Support Capabilities
Supporting processes and quality control to help maintain consistent quality across repeat production runs.
ISO 9001 quality control with routine in-process checks and final inspection, using appropriate measuring tools and inspection equipment. Inspection records and material certificates are available.
Automated loading helps run batch production more efficiently, reduce manual handling, and keep lead times and costs under better control.
We support anodizing, hard anodizing, plating, black oxide, sandblasting, polishing, tumbling, and other surface finishes for production parts.

Materials We Machine
We machine a wide range of metals and engineering plastics for CNC turned, milled, and multi-axis production parts.
Widely used for precision machined parts requiring strength, corrosion resistance, and durability.
Carbon, alloy, and tool steels for production parts requiring strength, wear resistance, hardness, or post-machining heat treatment.
Excellent machinability, good corrosion and wear resistance, and useful electrical conductivity for precision turned parts, fittings, connectors, valves, and repeat-production components.
High strength-to-weight ratio and excellent corrosion resistance for precision machined parts used in demanding, lightweight applications.
We specialize in machining POM, PTFE, nylon, PE, and other engineering plastics for precision components, with material options selected based on friction, chemical resistance, insulation, and weight requirements.
