Computer numerical control (CNC) machining is the process in which machine tools are used to remove material to make parts, also known as subtractive manufacturing. Most commonly, CNC machining is done with routers, lathes, and mills. Another form of CNC machining is electrical discharge machining (EDM), which uses electrical currents and dielectric liquids to pass current between electrodes and work pieces.
These processes allow a variety of different precision parts and shapes to be made in either plastic and metal and for prototype or production. The typical tolerances we hold can range depending on rapid prototyping and production as well as shape and material. We can regularly hold standard machining tolerances as low as +/-0.0005” and in certain applications within .0002” total tolerance.
No matter your industry, you can rely on our 5-axis CNC machining services, as well as our other advanced machine shop services. The team will optimize your project for production by creating cells for multiple operation production or for prototyping with fast and flexible changeouts that can run on multiple machines. Each project will have a project manager and an engineer working with you to find the best solutions for your project. Our equipment can handle a wide variety of materials, including titanium, stainless steel, Inconel® alloys, polycarbonate, polyvinyl chloride (PVC), acrylonitrile butadiene styrene (ABS), and polyetheretherketone (PEEK).
CNC milling is a very common process used to make rapid prototypes and production parts. Our CNC milling machines are 3- or 4-axis systems and include automatic tool changers that reduce setup and change over time between operations and parts. We dedicate our machines for ferrous and non-ferrous machining to reduce contamination of materials.
Most parts are created with material from sheets, bars, extrusions, forgings, or castings. CNC milling is best used with block-shaped geometries that require machined holes, faces, and features.
CNC milling is perfect for machining both small and large parts between 1” and 48” in length in all different plastic and metal materials.
CNC turning is another very common process used to make rapid prototypes and production parts. Our CNC lathe machines have bar feeders and automatic tool changers that allow for seamless production with less interruptions and breaks in cycles. Most parts are created with material that comes in bars, rods, and tubes. CNC turning is best used with cylindrical-shaped geometries that require inside and/or outside diameter surfaces machined to size and shape.
Our 9-axis CNC lathe with live tooling is a great option for producing production parts that require parts to be CNC turned and CNC milled in just one setup, which reduces cost and lead time while increasing quality by cutting out time-consuming and risky setups and operation changeovers.
Our CNC turning is ideal for parts with diameters >14" and >30" in length with all different plastic and metal materials.
True 5-axis CNC machining is a very specialized process with all five axes working simultaneously to make a complex part from a block of material. Examples of this are fan blades and compressor wheels, where they are made complete in one setup and at high speeds.
We operate the very best equipment in AgieCharmilles Mikron high-speed 5-axis CNC machines. Each machine is optimized for production with robotic pallet and tool change systems. These automation tools, along with IoT sensor technology, allow us to run lights out production.
5-axis CNC machining is a great option for production machined parts that require multiple setups, complex geometries, or just high-volume repeat production runs. Ideal parts are <14”, but larger parts can be made without using an automated pallet change system. Our equipment can handle all sorts of plastic and metal materials.
We make parts, tooling, and fixtures using our wire EDM, die sinking EDM, and hole drilling EDM machines. Our EDM wire and sinker machines and processes are NADCAP-approved for non-conventional machining. The NADCAP requires tightly controlled processes that can guarantee repeatable high-tolerance components. The EDM equipment we operate is specialized GF Machining Agie charmilles that leave incredible surface finish results with minimal recast layers.
Both wire EDM, using wire electrodes, and sinker EDM, using graphite electrodes, can remove excess material without much force. EDM is a great resource for machining all kinds of difficult geometries and metals, including difficult hardened metals.
In this competitive world with ever-changing technology, we need innovation partners that we can trust. Working with the team at The Technology House and Sea Air Space Machining & Molding over the past five years, I have grown to rely on their ability to deliver unique results and thus instruct my development teams to call them first. They constantly drive state-of-the-art solutions that exceed the expectations of our Medical Device Customers, delivering them at a great value!
