A turning center is an automated machining tool designed to machine cylindrical workpieces with high precision and efficiency. These machines combine the traditional functions of an engine lathe with the advanced capabilities of a CNC (Computer Numerical Control) system. This integration allows for the execution of complex and repetitive tasks with minimal human intervention, ensuring consistent quality and productivity.
Turning centers achieve high levels of accuracy and repeatability, which are essential for producing complex CNC turned parts. They reduce machining time and increase production rates, making them ideal for high-volume manufacturing. These machines are capable of performing a variety of operations, including turning, facing, threading, and drilling, making them suitable for a wide range of applications. Automation further minimizes the need for manual intervention, reducing the risk of human error and enhancing safety.
At our precision machining workshop in North East, PA, we utilize advanced CNC turning centers to deliver both custom machined parts and prototyped machined parts.
As a full-service CNC machine shop, Seymour Tool and Dye offers a range of HAAS turning centers to meet various needs.
The HAAS SL-20 is ideal for smaller workpieces, offering precision for light to medium-duty tasks and custom CNC parts with tight tolerances.
The HAAS SL-30 Big Bore is designed for larger workpieces, providing a greater diameter capacity. It is perfect for heavy-duty applications requiring robust performance and reliability.
The HAAS SL-30 offers greater flexibility in operations. It is well-suited for medium-sized workpieces, balancing capacity with precision for CNC turned parts.
The HAAS ST-30 is capable of handling a wide range of tasks with high precision. It is ideal for medium-duty applications, offering a good balance of size and capability.
The HAAS SL-40 model is designed for the heaviest and largest workpieces. It provides exceptional capacity and power, making it suitable for the most demanding machining tasks.

First, our experienced CNC machinists create a detailed program specifying the job requirements, including dimensions, cutting paths, and tool changes. This program is then uploaded into the CNC control system of the turning center.
Once the program is loaded, the machine turns the workpiece while cutting away excess material according to the programmed specifications. This process ensures consistent, precise shaping for every custom CNC part and reduces manual labor compared to engine lathes.
We can also integrate CNC milling services to complete features in a single workflow.
What materials can be processed in a turning center? Our CNC machine shop handles a variety of materials. Turning centers are commonly used on steel, iron, aluminum, and other metals. However, they can also be used on plastics and ceramics. What's the difference between turning and milling? A milling machine removes material by moving the shaping tool along a stationary piece of material. A turning machine, meanwhile, rotates the piece as the tool shapes it. We offer both turning and CNC milling services for complete, end-to-end projects. Can you machine complex shapes with a turning center? Yes! Turning centers can machine both simple and complex shapes. What are the most common applications for turning centers? Turning centers are most commonly used to make metal parts for the electronics, auto, and aviation industries. They can also be used to make toys and molds. Are there manual turning centers? A turning center combines the function of an engine lathe with the precision and accuracy of a CNC system. Therefore, our turning centers are all automated, operated by experienced CNC machinists.Turning Center
