Precise Point Grinding

Jouhsen-bündgens has redesigned its PrecisionGrind PG6 needle grinding machine. It features a new saddle close to the grind stone that allows the machine to now also process short blanks in the required length. Workpieces no longer have to be cut to length after grinding, optimizing the entire production process. The machine is capable of process speeds of up to 600 parts per minute in a continuous grinding process. To achieve this, a transport wheel separates the blanks from the magazine and precisely positions them axially. The blanks...

Polishing Technology for Different Freeform Surfaces

The Hong Kong Polytechnic University (PolyU) has developed a novel curvature-adaptive multi-jet polishing (MJP) technology for different kinds of freeform surfaces, i.e., surfaces without symmetry axis, which are widely used in high end products such as compound lenses in 3D imaging, head-up display (HUD) lenses used in automotive, optical components for augmented reality and virtual reality headsets, etc. Time efficiency and surface quality improvement were the main goals of the technology research. "This technology can meet the stringent...

Deep Part Marking Capabilities Expanded

Marking hard materials with a deep mark is vitally important to manufacturers in many industries today. Processes like painting, plating, heat-treating and subsequent machining can make shallow marks disappear, and in a manufacturing environment that requires absolute traceability, the right marking process must be applied. "Columbia Marking Tools, Inc. has pioneered the application development of many of the marking processes used in manufacturing today, including enhanced versions of dot-peen marking, low-stress dot-peen marking, imp...

Parabolic Performance Cutting Tool Family Expanded

Hoffmann Group USA has expanded its tool family for Parabolic Performance Cutting (PPC) to include a new PPC indexable insert and GARANT PPC solid carbide barrel milling cutters for high-alloy and hardened steels. The PPC process represents a further development of ball-nosed slot drill cutting and is also known as barrel milling. It is primarily used for finishing free-form surfaces in machining tool building, tool making and die making and is designed to achieve either up to nine times shorter processing times or a significantly improved surf...

Validate Worker and Student Inspection Skills with New NIMS Credential

The National Institute for Metalworking Skills (NIMS) has launched a new credential to validate an instructor's or evaluator's parts inspection skills. According to Montez King, Executive Director of NIMS, "validating skills has become ever more important to employers and of course a necessity for educational institutions offering certificate-type training programs in manufacturing technology. For our current customers, this is a refreshing evolution in the certification process." Designed for manufacturers and schools, the ne...
