If you’ve ever dealt with parts that don’t quite line up, require multiple operations, or need extremely tight tolerances, you already know how quickly traditional turning and milling can create problems. That’s exactly why the best machine shops rely on Y-axis CNC lathes to machine precision parts.
At QB Manufacturing, we’ve made large investments in Y-axis CNC lathes and Horizontal full 4-axis machines that allow us to combine turning and milling into a single, highly accurate operation - producing better parts, faster, and with fewer opportunities for error.
What Is a Y-Axis CNC Lathe?
A Y-axis CNC lathe is a type of turn-mill machine that allows milling tools to move off the centerline of the rotating part. Unlike traditional lathes that only turn parts symmetrically, a Y-axis machine can cut flats, pockets, slots, and drilled features - all without removing the part from the machine.
This makes it possible to produce complex components in one setup instead of three or four.
For manufacturers like you, that means:
Faster cycle times
Lower overall cost per part
Better concentricity
Tighter tolerances
Fewer handling errors
Why One-Setup Machining Matters
Every time a part is removed from a machine and reloaded, it introduces the possibility of misalignment. Even a few thousandths of an inch can cause:
Out-of-round features
Misaligned holes
Parts that won’t assemble correctly
By machining turning and milling features in the same setup, Y-axis CNC lathes maintain perfect alignment between all features - critical for precision components used in automation, packaging, food processing, and industrial machinery.
Did we mention it also saves time and money?
QB Manufacturing’s Y-Axis CNC Lathe Capabilities
QB Manufacturing operates two high-performance Y-axis CNC lathes designed for both precision and production.
DMG Mori NLX4000
20” diameter x 27” length capacity
6" partial thru hole
High-torque Y-axis milling
This machine allows our machine shop to produce large, heavy, or high-precision turned parts while also machining milled features without sacrificing accuracy.
(Faster and more economically)
DMG Mori NLX2500
14” diameter x 48” length
1"– 8" diameter steady rest
Full Y-axis milling
This lathe is ideal for long, slender, or complex shafts that require both turning and milling while maintaining tight straightness and concentricity.
CNC Horizontal Full 4 Axis
12,000 RPM Cat 50
31” working cube
Full B axis

When a Y-Axis Machine Shop Is the Right Choice
If your parts require any of the following, a Y-axis CNC machine shop is the best solution:
Cross holes or slots in turned parts
Flats or milled features on shafts
Multiple drilled or tapped features
Tight positional tolerances
High-volume repeatability
If you need your project done quickly and affordably
These are exactly the types of components QB Manufacturing produces for OEMs, automation companies, and maintenance departments that need parts that simply work.
Better Machines Mean Better Parts
Y-axis CNC lathes aren’t just faster - they dramatically improve quality. Fewer setups mean:
Fewer errors
Less scrap
Better consistency
Higher reliability in the field
And have we mentioned your jobs get done faster and more economically?
That’s why leading manufacturers choose a machine shop like QB Manufacturing when parts matter.
Work With a Machine Shop That Has the Right Tools
Not every machine shop is equipped to handle turn-mill work or complex multi-operation parts. QB Manufacturing’s investment in DMG Mori Y-axis CNC lathes allows us to take on challenging work that other shops simply can’t handle.
If your parts require precision turning, milling, or both - QB Manufacturing is ready to help.
