Inductive Fixture Hardening and Tempering Process for Dimensionally Accurate Parts
Automobile manufacturers increasingly require components with greater accuracy for use in sophisticated applications. To meet these increased requirements, press hardening was developed, and there are continued advancements in this field of applications. Inductive fixture hardening EMA-Indutec developed a new process that combines the benefits of induction heating/hardening with the advantages of a fixture or press […]
Nitrocarburizing Gears Using the ZeroFlow Method in Large-Volume Production
Retort-based nitriding and ferritic nitrocarburizing have been around a long time. Modern day challenges include providing known, repeatable hardness and surface case structures with the lowest possible investment and cost. While combining these factors may be difficult for equipment manufacturers, experience in designing equipment for challenging applications helps ensure meeting customer requirements. Here is a […]
Ion Nitriding of Ferrous and Titanium Alloys for Gear Applications
Thermochemical surface engineering is effective in improving the performance of various gears made of ferrous alloys [1-5]. The cost of machining typical gears during the manufacturing process often exceeds 55 percent of total cost, especially when there is significant grinding after carburizing the gears [5]. Therefore, improvements in the manufacturing of gears that can lead […]
Advanced Robotics Combined with Eddy Current Testing Offers Verification Methods for Heat-Treated Gears
Eddy current is a nondestructive testing technique proven for use in heat treatment and material structure verification. Modern multifrequency eddy current instruments can test for conditions such as misplaced case, shallow case, short heat, short quench, and delayed quench. Gears, bearings, axles, shafts, and other components are heat treated to develop the required strength and […]
Optimizing Case-Depth Uniformity in the Vacuum Carburizing Process
Over the past few decades, the vacuum carburizing process has been proven to produce superior part quality. In addition, the use of vacuum technology for carburizing has the most potential to improve the manufacturing process by reducing both processing time and the number of manufacturing steps required to produce a part [1]. These savings are […]
