CNC Turn-Mill Machining Services | Multi-Axis Turning

Complex Geometry. One Setup. No Compromise.

When a part needs turned diameters, milled flats, cross-holes, and off-center features — and tolerance stack-up from multiple setups isn’t acceptable — turn-mill is the answer. MicroPrecision’s multi-axis turn-mill centers handle complex geometry in a single chucking, eliminating re-fixturing error and compressing lead time.

The Turn-Mill Problems We Were Built to Solve

The Issue: “The part needs turned and milled features but we’re getting re-fixturing error”

The Fix: One Setup. One Reference. Zero Stack-Up.

Our turn-mill centers complete turned diameters, milled pockets, flats, cross-holes, and off-center features in a single chucking. The part never leaves the spindle until it’s done — so positional relationships stay exactly where the print says they should be.
The Issue: “We’re juggling two shops and the lead time is killing us”

The Fix: Done Here. Shipped From Here.

Turned and milled features under one roof means one purchase order, one lead time, and one quality record. No hand-offs, no re-inspection at a second shop, no lost time.
The Issue: “Our current shop can’t hit the tolerances on the off-center features”

The Fix: Multi-Axis Precision Is What These Machines Are Built For.

Our turn-mill centers run live tooling with full Y-axis capability. Off-center bores, radial holes, and milled flats hold the same tight tolerances as the turned diameters — because they’re cut on the same machine, referenced to the same datum.

Where Turn-Mill Is the Right Tool

Hydraulics | One Part, Every Feature

Valve bodies and manifold components with ported cross-holes, turned sealing diameters, and milled mounting flats. Turn-mill produces these complete — no secondary operations.

Medical Equipment | Positional Accuracy That Protects Patients

Actuator housings, locking mechanisms, and pivot components where off-center features must relate precisely to turned diameters. Re-fixturing introduces risk. We eliminate it.

Automation | Complex Parts, Consistent Quantities

High-mix automation components that combine multiple feature types in a single part. Turn-mill keeps your per-part cost down without sacrificing the geometry your assembly requires.

Oil & Gas | Exotic Alloys, Complete Features

Downhole and offshore components in Inconel, Monel, and titanium — machined complete in a single setup to avoid re-fixturing high-value raw material.
