CNC Machining Services for Production Parts
Mastro Machine Shop supports OEMs from new part development through stable repeat production. We also support existing production parts when customers need a new source or additional capacity.
With years of machining experience and ISO 9001 quality control, we focus on consistent quality, reliable production, clear communication, and responsive support from development through repeat production.
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.
Heat Treatment
We support a range of heat-treatment and hardening processes, including vacuum heat treatment, nitriding, induction hardening, laser hardening, and QPQ, to improve hardness, wear resistance, and durability for production parts.
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.
Aluminum
Lightweight and versatile, widely used for precision machined parts with anodizing and other surface finishing options.
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.
