Material Expertise

 At Turntech Precision, we understand that material selection is critical to performance, reliability, and manufacturability. Our team brings deep experience in machining a wide range of materials — from corrosion-resistant stainless steels to high-performance engineering plastics — with tight tolerances and consistent quality.

Whether you're producing components for medical, food processing, marine, or high-precision industrial applications, we’re equipped to machine your parts right the first time, every time.

Stainless Steel Expertise

Stainless steel machining is a core strength at Turntech Precision. We regularly work with austenitic grades like 303, 304, and 316 series materials — each with unique properties requiring specific tooling, speeds, and strategies for optimal results.

Whether it’s for medical, food-grade, marine, or high-precision industrial components, we understand how to machine stainless efficiently, cleanly, and consistently.

 

Common Grades We Machine

303 & 303Cu

  • Excellent machinability due to sulfur content

  • Used in fittings, fasteners, and high-volume turned parts

  • 303Cu adds copper for improved surface finish and cold workability

  • Ideal for small, detailed parts requiring good chip control

See our breakdown on 303 vs 304.

 

304

  • Widely used, all-purpose stainless

  • Good strength and corrosion resistance

  • Preferred in food, medical, and structural applications

  • Less machinable than 303, but more weldable and formable

 

316 / 316L / 316F

  • Enhanced corrosion resistance for marine, pharma, and harsh environments

  • 316L: Low-carbon for welds and corrosion protection

  • 316F: Free-machining variant for tighter tolerance work

  • Optimized for smooth surface finishes and dimensional control

Process Expertise

Each grade requires a different approach — and we’ve dialed in the right parameters for consistent results. From small shafts to complex fittings, we deliver stainless parts with tight tolerances, clean finishes, and minimal variation.

Engineering Plastics Machining

Not all parts are best made from metal. At Turntech Precision, we specialize in engineering plastics — materials that combine low weight, chemical resistance, and electrical insulation with excellent wear and thermal performance.

These plastics are used across industries like medical, aerospace, automation, and semiconductor tooling, where metal simply falls short.

Because plastics behave differently under heat and tool pressure, we use dedicated setups, optimized tooling, and strict contamination control to ensure consistent results.

Materials We Machine

POM (Acetal / Delrin®)

High-Performance Plastics

PEEK

  • Excellent at high temps and chemically aggressive environments

  • Used for medical and aerospace components

Ultem® (PEI)

  • Strong, flame-resistant, and electrically insulative

Vespel®

  • Performs at extreme temps with excellent wear and dimensional control

Torlon®

  • Among the strongest thermoplastics; ideal for load-bearing parts

Semitron®

  • Cleanroom-ready and ESD-safe; used in wafer handling and testing

  • Stable, low-friction, and machinable

  • Used for gears, bushings, and valve bodies

Nylon (PA6 / PA66)

  • Lightweight and wear-resistant

  • Ideal for washers, spacers, and rollers

PTFE (Teflon®)

  • Inert, non-stick, and thermally stable

  • Great for seals and insulators

UHMW-PE

  • Low friction and high impact resistance

  • Common in liners, guides, and wear strips

Ready for Polymer Precision

Whether for 10 parts or 10,000, Turntech delivers reliable, high-performance plastic machining — ready for the most demanding applications.

Let us help you choose the right material and manufacture with confidence.

Consistent Results, Material After Material

Whether it's a medical fitting in 316L, a marine-grade shaft in 316, or a high-precision valve component in PEEK, we know how to manage material-specific behaviors like:

  • Work hardening in stainless steels

  • Burr control in free-machining grades

  • Chip evacuation and thermal expansion in plastics

We bring the right speeds, feeds, tooling, and handling strategies to each job, so your parts meet spec — no matter what they’re made of.
