CNC Machining Capabilities

CNC Milling

CNC Milling

CNC milling employs a subtractive method, utilizing both 3-axis and 5-axis indexed milling techniques to carve out final parts from solid blocks of plastic and metal.
CNC Turning

CNC Turning

CNC turning with live tooling merges the functions of a lathe and a mill, enabling the machining of parts with cylindrical attributes directly from metal rod materials.

Why Choose Us for Custom CNC Machining?

Advanced Capabilities

Access a range of manufacturing enhancements including anodizing, precise tolerances, and competitive volume pricing through Hubs' extensive network of manufacturing partners. Discover options for plating (such as black oxide and nickel), Type II and Type III anodizing, and chromate coating for bulk orders. Benefit from tolerances as precise as ±0.001 inches (0.020mm) and cost savings on machined parts with larger quantity orders, resulting in reduced per-part costs.

Material Selection

Our inventory encompasses over 30 engineering-grade plastics and metals, tailored for diverse part applications across multiple industries. This selection includes materials such as ABS, polycarbonate, nylon, PEEK, along with metals like aluminum, stainless steel, titanium, and copper, catering to a wide range of manufacturing needs.

Fast and Reliable Delivery

Speed up your product development and refine part designs rapidly with our fast-turnaround parts. Our automated design analysis identifies any features that may be challenging to machine before your design reaches the manufacturing stage, preventing expensive modifications later in the product development process.


CNC (Computer Numerical Control) machining is a manufacturing process that uses computer-controlled machine tools to shape material into precise parts. It works by converting a digital model into a set of computer instructions, which control the cutting and shaping tools to create the part from a solid block of material.

Our CNC machining services can handle a wide range of materials, including metals like aluminum, brass, copper, stainless steel, and plastics such as ABS, polycarbonate, nylon, and PEEK. This versatility allows us to cater to various industries and applications.

We accept several 3D CAD file formats, including STEP, IGES, and STL. These formats allow us to accurately interpret your design into machinable parts.

Yes, we are equipped to handle both small-scale prototype projects and large-scale production runs. Our flexible manufacturing capabilities allow us to provide you with precisely what you need, whether it’s a single prototype or thousands of parts.

Our CNC machining services can achieve tight tolerances typically within ±0.005 inches (±0.127mm). However, tolerances may vary based on the material and part complexity. We strive to meet the specific tolerance requirements for your project.

We aim to provide quotes within 24 hours of receiving your CAD files and project specifications. Complex projects may require additional time for accurate quoting.

The lead time for CNC machined parts depends on the complexity of the parts and the volume of the order. Typically, our lead times range from 1 to 3 weeks. We also offer expedited services for urgent projects.

Yes, PCBPit offers a variety of finishing services, including anodizing, plating, powder coating, and painting. These finishes can improve the appearance, corrosion resistance, and surface hardness of the machined parts.

We adhere to strict quality control procedures throughout the machining process, including material inspection, in-process inspections, and final dimensional and visual inspection. Our commitment to quality ensures that your parts meet both our standards and yours.

Absolutely. Our engineering team can review your designs and suggest modifications that can improve manufacturability, reduce costs, and maintain the integrity of your parts. This collaborative approach helps ensure the success of your project.
