Custom Flexible Shafts

Custom flexible shafts are available from S.S. White Technologies, St. Petersburg, FL. Flexible shafts transmit rotary motion much like a solid shaft, but can be curved over, under, and around areas in ways a solid shaft cannot. This allows the minimally invasive applicator systems to position the proximal and distal ends of an implant (an anchor) within a blood vessel and to deploy the spiral anchor into the vascular wall. Flexible shafts are commonly used in surgical applications, especially in surgical power tools and tools used in minimally invasive procedures. Typical uses include handheld screw drivers, heart valve repair, laparoscopic and endoscopic surgical equipment, and robotic assisted surgery technology.

CT Software

Volume Graphics, Charlotte, NC, has released the latest generation of its software for nondestructive quality assurance with industrial computed tomography (CT). VGSTUDIO MAX software is used for the analysis and visualization of industrial CT data and covers all requirements related to metrology, defect detection and assessment, material properties, and simulation. Using Version 3.3, users can determine the surfaces of multi-material components, export measurement and analysis results to store them centrally in quality-management software, automate inspection processes more flexibly based on text recognition, and translate real CT data into volume meshes for simulation.

Variable Drive Measurement

Mahr, Providence, RI, has added a variable-drive series that enables roughness and contour measurements to be performed on the same machine. With the MarSurf VD, the operator can easily and quickly change between a high-precision roughness probe system or a highly dynamic contour probe system, depending on the measuring task. The new variable drive series combines contour measuring and the surface finish measuring into a single unit. It is available in drive unit sizes of 140 and 280 mm, which allows for the measurement of larger parts or a series of smaller parts staged together. The series also significantly increases the speed of all moving axes to reduce the cycle time of the measurement process.
