The performance of an Electric Vehicle Power Unit is directly connected with critical tolerances. Tolerances drive opportunities for performance enhancement with cost reduction. The tests normally used to determine and validate tolerances are both expensive and time consuming with prototype parts. By replacing the initial tests with Digital Twin simulations, results can be obtained quickly, and at a much lower cost. This article discusses one of these tests and the results. 

JTEKT recently demonstrated a new double-disc horizontal grinder that simultaneously grinds both sides of silicon wafers to +/- 1 micron from as-sliced condition. The DXSG320 performance represents a massive improvement in accuracy and productivity over the single-spindle vertical grinders common in the chip industry today which grind to 3-4 microns, according to the company.

How can the protective layer be applied to the brake disk more quickly and more effectively? And how can it be made to stay on for longer? “The solution is intelligent coatings, as can be applied to brake disks using our AM coating system” says Dr. Géza Koscsák - the head of additive mat the Chiron Group. He has played a prominent role in developing the new system and reaching the decision to opt for the high-speed deposition welding process in his previous job as head of advanced development. 

Roundness testers, surface analyzers and lead angle detection inspection benches - instrumentation to measure roundness, cylindricity, surface finish and lead angle shaft seals have all existed separately for a long time. The Hommel-Etamic (HE) Roundscan system incorporates all these measurements into one robust automated inspection system for metrology lab and shop floor production applications.

esco, technology partner for process digitization in the gear and cutting tool industry, is expanding its software offering with the new eSkiving.FS module for effective feasibility studies in gear skiving. At the same time, the company is introducing ePP, a comprehensive software platform that includes eSkiving.FS to provide seamless support in all areas of the gear skiving process.

STUDER focuses on universality and speed with the uniLoad loading system. The automatic loading system enables users of the S31 and S33 external cylindrical grinding machines to increase quality and productivity.

Soft jaw blanks from Dillon Jaws feature a milled surface on the jaw end, opposite to the clamping surface, which serves as an easy-locating feature. 

GWJ Technology GmbH presents the new version of its system calculation software SystemManager as an extension of its well-known solutions eAssistant as a web solution and TBK as a classic desktop application.

DN Solutions introduces the new PUMA DNT 2100 and 2600. The DNT Series will replace the PUMA GT 2100 and 2600 models. The PUMA DNT Series is equipped with a powerful spindle, a redesigned turret body, and a live tool drive that guarantee powerful and precise machining and exceptional productivity. The design of the new machines focuses on convenient operation and easy maintenance.
