Precision CNC Machining for Large Components
Micromachining requires a high level of skill and expertise, not excepting CNC machining of large components that need specialized equipment large enough to process large-scale productions. Therefore, many industries rely on manufacturers like Runsom to fabricate oversized precision components that are too heavy to move quickly by a person alone, or too large to fit into a standard CNC machine.
Runsom Precision delivers precision CNC machined large components for diverse applications across a wide variety of industries. Our team of engineers and machinists can employ advanced machinery and the latest machining techniques to process complicated components with intricate geometries and high quality, whether you need prototype production or medium-volume production runs.

Aerospace Large CNC Machining
Some aerospace components have large internal cavities, such as compressor housings or engines. For instance, a CNC machine must core out a large block of material to produce the transmission casing for helicopter blades. This process consumes much time, incurs material waste, and causes residual stress in the part. Problems like deformation or warping would occur due to the residual stresses and influence the required tolerance and standard in return.
At Runsom, our machine shop has equipped with state-of-the-art 5-axis CNC machines with high performance and better control capabilities of power, speed, and force. That makes it possible to machine aerospace parts with thin walls in large sizes without applying too much force to deform them. Additionally, we can machine parts symmetrically using ADOC (axial depth of cut) or RDOC (radial depth of cut) to distribute forces and thus reduce residual stress.

Our Large Capacity Machining

Integrated Manufacturing Process
Runsom has the capability to offer an array of machining techniques such as milling, turning, drilling, threading, grinding, etc. Moreover, we also offer CAD design, reverse engineering, rapid tooling, secondary processing, and assembly.
Top-notch Machining Equipment
Our high-performance vertical and horizontal machining centers and large swing lathes allow us to produce components with dimensions up to 394” L x 138” W x 84” H. with a vast variety of metals like aluminum, stainless steel, brass, titanium, and plastics. And with our 5-axis boring capacity accommodating materials up to 50 tons, we can make complex, large components with tight tolerance.
Guaranteed Quality
Our Coordinate Measuring Machine (CMM) is one of the basic working machines for product verification. We daily employ it to validate rapid prototypes and large machined parts with intricate geometries and tight tolerances.
The goal of the dedicated staff at Runsom is the pursuit of building high-quality products to fulfill clients’ requirements even beyond their expectations.
Convenient Transportation Services
Upon the completion of the manufacturing of large components, we can deliver them to your location with safe and fast transportation for your convenience.

Why Choose Us?
Component manufacturing is an arduous process from precision and stress to tooling and tolerances. All of these challenges are magnified when parts are heavy and large. It’s a daunting task for some shops that just move the material around. But at Runsom, we’re proud of the efficiency and capacity of fabricating heavy-duty components to meet our customers’ requirements and needs. That means we have the confidence and capability to handle projects that may be too complex or difficult for other machine shops.
