The WSE Maryland Machine Shop
The Whiting School of Engineering Maryland Machine Shop is operated by the Office of the Dean of the Whiting School of Engineering. Until August 2011, the shop's Senior Instrument Designers, Walt Krug and Mike Franckowiak, had a combined total of 88 years of custom machining service between them, and, a combined total of 64 years spent at Johns Hopkins University. After 37.5 years at the Maryland Machine Shop Walt Krug recently retired. He is greatly missed.
Mike Franckowiak continues at the Machine Shop and has a new partner - Frank Cook - who most recently worked at the Applied Physics Lab. Each Senior Instrument Designer brings a wide array of skills and abilities to handle the most complicated of engineering research ideas, prototypes and inventions. The Machine Shop is located on the ground floor of Maryland Hall in Room 30 and handles work from all over the Johns Hopkins University's enterprises including JHU-Homewood and JHMI-SOM. Additional research and project work also comes to the Shop from sister-institutions in the Baltimore area, including Loyola College and the University of Maryland.
For all interested Faculty, Staff and Students please contact Shop personnel by e-mail or telephone - lhb@jhu.edu or 410-516-7146. Further, you may make an appointment or stop by the Shop in-person to discuss your project.
To request services please complete a Service Request form and seek budgetary approval from your Department or Center Administrator prior to submitting the request to the Maryland Machine Shop.
"Before any project leaves the Shop, it must work for the purposes intended." - Walt & Mike, 2011

Below are examples of work carried out by the Maryland Machine Shop. Their skills stretch across a wide array of abilities - from mm sized medical device instruments to huge component parts of a Fluid Dynamics Lab's axial pump facility.

Image-Guided Intra-Cavity Robots for Prostate Interventions
Dr. Russ Taylor
MRI-guided Prostate Robot design modifications & fabrication - Walt Krug & Mike Franckowiak
Computer-Integrated Surgical Systems and Technology are developing systems that augment the physical and sensory performance of a surgeon during the performance of a procedure. These systems are designed to work cooperatively with the surgeon in a dynamic or context-dependent fashion.These pictures show a high-dexterity "snake" robot and gripper for minimally-invasive surgery. Each robot end effector has 7 degrees of freedom (in-out, rotation, 4 bending directions, and gripper). The discs in the shaft of the instrument are approximately 4 mm in diameter and the gripper is approximately 5 mm. Further information »
Laboratory for Experimental Fluid Dynamics
http://web.jhu.edu/fluid_dynamics/index.html
This laboratory examines a wide range of problems involving complex flows and particle dynamics. We have developed and implemented quantitative flow visualization techniques for laboratory and field applications including PIV, film-based and digital holography, holographic PIV, microscopic holography and pressure measurement techniques.
