The Mechanical Core is highly skilled in a variety of fabrication, customization and repair services for mechanical devices and equipment. We are proficient in precision machining of metals and plastics, welding of structural and exotic metals, instrument refurbishing and mechanical repair.
Our personnel can work from concept sketches to design and fabricate new devices, test research fixtures and equipment. Documentation of the newly created part or device is also available through two-or three-dimensional computer-aided design (CAD) drawings. We also use SolidWorks and AutoCAD software. CAD drawings can be converted into computer-aided manufacturing (CAM) programs that are directly fed into the Computer Numerical Control (CNC) machines to fabricate the desired parts or can also manufacture with a variety of manually machines depending on the complexity of the parts geometry.
The equipment at our disposal allows us to create high-precision devices for a wide variety of clinical or research applications. Examples of devices that have been produced by this facility include acrylic cranial windows, a brain tissue environmental chamber, a myocardium rapid-freezing device and a mitral valve repair frame. With the combination of our trained technicians and advanced equipment, we can help you develop a custom device that will enable you to complete projects or procedures. Some of our machining equipment include:
Packed into our 5000 square foot facility are four CNC vertical machining centers (VMC). SV-400 Mori Seike 5 axis Mill, a four axis Mori Seike SL-150 Lathe, 4 axis Mitsubishi Wire Electro Discharge Machine (WEDM) shown, Bridgeport EZ Path Lathe, Two Bridgeport EZ Path Mills, Three axis F1012E Precision Mill, 2 axis Precision Lathe, and a Hass VF2SS 4 axis vertical machining center.
Currently we use a Next Engine 3D laser scanner, Mitutoyo Profile Projector, Rockwell Hardness tester and a myriad of the regularly found machine shop inspection tools.
Instrument Manufacturing and Refurbishing
Old, dull and/or damaged instruments can be returned to like-new condition.
We sharpen, polish, weld, straighten and make replacements for broken or lost components. Instruments can be uniquely labeled using our etching process.
Custom instruments can be designed and manufactured, and we can make copies of discontinued items for clinical or research use. Most of our instrument services can be performed in one day or less if required.
Mechanical Device Design and Development
Core personnel can provide as much design assistance as is required. We accept jobs ranging from someone needing a simple part in a hurry to working with your detailed engineering drawings. We can provide input on materials, geometries, drive mechanisms and instrumentation. Often hand-drawn sketches are sufficient, but full computer-aided design capabilities are available.

The Mechanical Core designed and constructed an innovative treadmill that may help astronauts keep their motor skills sharp after long weightless journeys. The treadmill has two independently operated treads with actuators at each end that can raise and lower vertically, incline and decline, and change speeds. It also has a virtual reality screen that immerses the user into an environment ranging from walking down a path, stair climbing or hiking along a curved trail. Developed as a proof of concept, the device will let astronauts simulate a walk, for example, on the Appalachian Trail, walking up and down hills, around curves and occasionally stepping over rocks and logs. Whatever happens on screen is reflected in the speed and pitch of the treadmill. The treadmill was developed to address issues related to deconditioning of the neurovestibular system in weightless environments. The neurovestibular system consists of visual (eyes and perception), vestibular (inner ear and balance) and proprioception (muscles and position) signals and helps human beings maintain their balance and stability while walking and moving on Earth. But in space, this is a problem for astronauts as they do not know up from down since gravity is negligible. This produces visual disorientation, thinking things are upside down when they are not. It also causes space motion sickness and decreased coordination. Upon returning to Earth, astronauts have balance disturbances, disorientation, and impaired coordination and locomotion. Their bodies have to readjust upon entering space and returning to Earth.
