CNC PRECISION TURNING

Spindles & Turrets

A lathe uses a spindle to hold and rotate the workpiece, which allows the cutting tool to remove material.

A turret holds multiple cutting tools and allows for rapid switching between tools which are held stationary against the workpiece to remove material. Some turrets themselves can move on multiple axes via CNC controls, giving greater freedom of motion for the cutting tool to create more complex shapes.

Advanced CNC turning machines can contain multiple spindles and multiple turrets which allows for very complex components to be machined with greater efficiency as both ends of the part can be worked on simultaneously.

EMI has more than a dozen CNC turning machines, some with multiple spindles and/or turrets and many with automatic bar feeders for automating long production runs. No matter the simplicity or complexity of your part, EMI can handle the job and will assign it to the appropriate machine to keep your costs low for any volume you need.

Our expertise allows us to machine parts with tolerances as tight as ±0.0001″ (±0.00254 mm).

Mill-Turn Centers

EMI's roster also includes a range of machines that combine both milling and turning.

As you might imagine, mill-turn centers include both milling and turning operations. Milling uses a rotating cutting tool on the workpiece, while with turning the cutting surface does not rotate.

The benefits of using a mill-turn machine are shorter cycle times, reduced material handling and increased precision for parts that require both operations.

EMI can select from more than a half dozen mill-turn centers on our floor to complete your complicated parts quickly and efficiently.

Horizontal and Vertical Turning Lathes

As with milling machines, the lathe spindles can be oriented either horizontally or vertically. Horizontal lathes are better suited for working on longer, thinner, higher production parts, while vertical tuning machines are preferred for larger and heavier workpieces where gravity can be used to help clamp it in place.

EMI has both horizontal and vertical turning machines so we can bring the right machine to bear to complete your project on time and on budget.
