• Vertical Mills
  Five vertical milling machines combined with machine fixtures and tooling increase the versatility of our milling machines. As a result, we can generate geometries as complex as conventional milling allows.
• Lathes
  Four engine lathes of various sizes are specially suited for high precision custom work. Capabilities range from turning large diameters (21") to holding extremely high tolerances.
• Multiple Welding Disciplines
  Our TIG (Tungsten Inert Gas), MIG, Plasma welding and cutting, Oxy-Acetylene and Arc welders allow us to weld a variety of materials including stainless steel, steel, aluminum and titanium. We are well versed in Brazing, silver soldering and tin soldering.
• Precision Surface Grinding
  Three types of grinders allow us to achieve lustrous surface finishes on hardened materials such as chromium cobalt, hardened tool steels, carbides and heat-treated stainless steels while holding extremely close tolerances.
• Surface Finishing
  The look of the final product is what matters giving devices a good looking outer finish we use either one of our two bead blasting methods. We have aluminum oxide beads that give a slightly dimpled finish, or silicon carbide chips that give a deeper etched finish. To add text or designs to any metallic face we have an electrical etcher that burns the desired display into the surface of the device. Polishing and buffing to mirror finish is our signature.
• Heat Treating
  With our high precision temperature-controlled programmable electrical furnace, we can provide a range of heat treatments for steel items up to 4" x 6" x 12". We also work closely with local heat treaters to fill voids where our capabilities leave off.
• Shears/Breaks
  Standard metalworking equipment is available for shearing, bending and forming sheet metal and bar stock.
• Plastic shop
  Our plastic shop is where most of the fabrication of acrylic, polycarbonate, ultem, polysulfone and other plastics is performed. The shop also handles wood in order to make fixtures or low devices for various research projects.

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.

Services Provided: Designed & Constructed Treadmill / Electrical / Machining / CAD / CAM Welding of Aluminum & Steel / Pneumatics.

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.
