CNC WIRE BENDING SERVICES
Start with a wire or tube having multiple machined features…
then bend the it so the features always emerge in the same location. That’s Marshall’s niche.
2D & 3D CNC WIRE BENDING AND TUBE BENDING FOR MEDICAL DEVICES
Marshall has been providing small diameter 2D/3D CNC wire & tube bending services since 2004. It soon became evident that a new underserved market opportunity had been discovered. Market demand inspired the development of proficiency in bending new materials, custom tooling and proprietary software. Marshall continued to expand their proficiencies in 2D and 3D wire & tube bending services and has become a premier provider to the medical device market.
CNC Wire & Tube Bending
CNC 3D bending of wire and tubing produces cost savings, faster prototypes, faster production and consistent quality.
We specialize in two specific forms of CNC bending at Marshall Manufacturing:
Marshall’s CNC bending machine uses two main bending modes: freeform bending and rotary draw.
Freeform bending pushes the product through two or more rollers, which put pressure on the sides of the part to create the desired curves. These rollers can be used to create a variety of complex 3D shapes as well, including helixes and curls. Rotary draw bending pulls the product around a second mandrel to achieve the desired bend. When required, these two forms of bending can be used together to process a single part. Explore the video above for specifics on how CNC bending machines operate at Marshall—and how our unique process delivers greater value and production efficiency for our medical customers.
More about Marshalls Capability
Many medical device components made from wire stock begin their processing in a CNC Swiss Machine. Required features for this type of a medical device component can include special turned diameters, milled flats, slots, grooves, knurling, cross-holes or axial holes. CNC Swiss machining can provide these types of features prior to the CNC 3D wire bending operation. At Marshall, this manufacturing technology can be used to craft custom 2D and 3D shapes in wire diameters ranging from .062 to .156 inches. Our CNC wire bending capabilities are compatible with a variety of materials, including stainless steel, titanium and many other metals—and support component lengths of 5.75 to 60 inches.
Medical device components made from tubing, which later require bending, often begin their processing in a CNC Laser Tube Cutting Machine. CNC laser tube machining is a very precise method for cutting features through the tubing wall prior to the CNC 3D bending process. CNC tube bending uses the same powerful bending technology to fashion metal tubes into specific shapes. Marshall Manufacturing offers custom 2D and 3D bending for tubes from .062 to .187 inches—allowing many features and configurations to be designed into these specialized components. Experienced in working with a variety of materials such as L605, MP35N, stainless steel with component lengths from 5.75 to 60 inches.
WHAT IS CNC BENDING?
Computer numerically controlled (CNC) bending is a unique manufacturing process that uses a robotic arm to push wire or tube through a series of servo-driven rollers to bend and form materials into specific configurations. At Marshall, our machines are capable of generating complex bends in both wire and tubing materials, bringing exceptional accuracy and repeatability to medical device component production.
Marshall’s automated CNC programmable bending system incorporates 2- and 3-dimensional precision bending for small-diameter, pre-machined wire and tubing. This advanced bending solution offers our medical customers; cost savings, improved production turn-around and consistent quality.
