How We've Helped Our Clients Succeed
Challenge
An automotive client needed a high-volume production run of custom stainless steel sensor housings with complex internal grooves and external threads.
Solution & Result
We utilized our CNC lathes with automated bar feeders to run the parts lights-out, achieving a 20% cost reduction and delivering 20,000 perfectly consistent parts on schedule.
Challenge
A communications company required a series of brass RF connectors with extremely tight concentricity tolerances (±0.005mm) for optimal signal integrity.
Solution & Result
By using our high-precision Swiss-style lathes, we were able to hold the critical concentricity and deliver parts with a superior surface finish, significantly improving the client's product performance.
Challenge
A machinery manufacturer needed a complex drive shaft made from 4140 alloy steel, requiring both turning and milled features like keyways and flats.

We produced the part in a single setup on our multi-axis turning center with live tooling. This "done-in-one" approach guaranteed perfect feature alignment and reduced the lead time by 40% compared to using separate machines.
CNC Turning FAQ
What is the main difference between CNC turning and milling?
In turning, the workpiece rotates while a stationary tool removes material, which is perfect for creating cylindrical parts. In milling, a rotating tool removes material from a stationary workpiece, which is better for creating prismatic shapes, pockets, and holes.
What is "live tooling" on a CNC lathe?
Live tooling refers to powered, rotating cutting tools (like end mills and drills) mounted in the lathe’s turret. This allows us to perform secondary milling, drilling, and tapping operations on the part without moving it to a separate milling machine.
What is the maximum diameter and length you can turn?
Our turning capabilities can accommodate parts with diameters up to [Insert Max Diameter, e.g., 400mm] and lengths up to [Insert Max Length, e.g., 1000mm]. Please contact us for specific inquiries.
What is Swiss-style turning?
Swiss turning is a specialized type of CNC turning where the workpiece is fed through a guide bushing. It is ideal for producing very small, long, and slender parts with extremely high precision.
What kind of tolerances can you achieve with CNC turning?
We can consistently achieve diametrical tolerances of ±0.01mm (±0.0004″). For critical features, even tighter tolerances are possible depending on the material and part geometry.
What is a bar feeder, and what is its advantage?
A bar feeder is an automated system that continuously feeds long bars of material into the CNC lathe. This allows for uninterrupted, “lights-out” production of thousands of parts, which significantly reduces the cost per part for high-volume orders.
