Our CNC Machining Equipment

CNC machining is a term that encompasses a wide range of subtractive manufacturing processes, such as milling, turning, and drilling. The machines employed in a CNC machining operation depend on the part and production processes. For example, the production of turned parts requires the use of a lathe or turning center, while the production of drilled parts requires the use of a drilling machine.

In addition to being classified based on the process performed, CNC machines can be categorized by the number of movement axes they have:

• 2-axis CNC machines: movement along X-axis and Y-axis
• 3-axis CNC machines: movement along the X-axis, Y-axis, and Z-axis
• 4-axis CNC machines: movement along the X-axis, Y-axis, and Z-axis and rotation around the X-axis
• 5-axis CNC machines: movement along the X-axis, Y-axis, and Z-axis and rotation around the X-axis and Y-axis

3-axis CNC machines are the most commonly employed as they can accommodate most standard machining needs. CNC machines with movement capabilities in four, five, or more axes are generally used in manufacturing operations involving more complex and intricate designs.

Our ISO 9001:2015 facility is stocked with a variety of state-of-the-art machining equipment, including the following:

These machines rely on GibbsCAM®, an advanced computer-aided manufacturing (CAM) system that guides the movement and operation of the machine tools. By using them, we accommodate machining requests involving the following:

• Processes: drilling, boring, counterboring, countersinking, reaming, and tapping
• Materials: a wide range of metals and plastics
• Tolerances: ±.001 inches for straightness and ±.0005 inches for concentricity
• Surface finishes: various 10-64 micro-finishes

The PEP Manufacturing team is fully dedicated to meeting every machining need. By partnering with us, our customers benefit from our:

• Extensive industry experience. We’ve been in business for over 20 years and have over 40 years of combined manufacturing experience.
• Commitment to quality. We ensure our machines are up to date and our employees are aware of any new machining practices. Additionally, our team continuously looks for ways to improve efficiency by reducing the amount of time and money that goes into each project.
