Why Choose Us for Custom CNC Machining?
Fast and Reliably Delivery
Iterate part designs quickly and accelerate product development with quick-turn parts. Our automated design analysis will help spot any difficult to machine features before your design is sent to the manufacturing floor and save you from costly reworks further down the product development cycle.
Manufacturing Analysis and Online Quotes
When you upload your 3D CAD file to request a quote, we'll analyze your part geometry to identify any features that may be difficult to machine such as tall, thin walls or holes that cannot be threaded.
Domestic Production and Support
Work with a trusted U.S.-based manufacturer and eliminate the risk of sending parts overseas. You can also call or email us at any time and we'll help with ordering parts, design feedback, material recommendations, and answer any questions.
Eliminate downtime spent waiting for parts and safeguard in-house machining with on-demand relief and infinite manufacturing capacity.
We stock more than 30 engineering-grade plastic and metal materials that are suitable for various part applications and industries. Materials range from plastics like ABS, polycarbonate, nylon, and PEEK to aluminum, stainless steel, magnesium, and copper.
CNC Machining FAQs
How much does CNC machining cost?
Prices start around $65, but vary based on complexity, quantity and lead time. The best way to find out is to submit a 3D CAD model and get an interactive quote with design for manufacturability (DFM) feedback. Because we use proprietary software and automated fixturing processes, there are no up front non-recurring engineering (NRE) costs. This makes purchasing quantities as low as 1 to 200 parts cost effective. Prices compared to 3D printing are comparable to somewhat higher, but machining offers improved material properties and surfaces.
What types of threading options are available?
We offer UNF, UNC, and metric threads for machining along with coil and key inserts (but do not supply or install the inserts). These are available on both milled or turned CNC parts. View this page to see our complete threading options.
What is the maximum part size for CNC machining?
Maximum part size will vary based on your selected material. Our largest part size offered is 22 in. x 14 in. x 3.75 in. (559mm x 356mm x 95.25mm) and is available in Aluminum 6061 and 7075. View this table to see maximum dimensions by material.
