Thread grinding takes many forms, including internal grinding, CNC grinding and OD grinding. Many different industries benefit from thread grinding for their tools and machine parts. These items range from cavities to core pins and, depending on their use, need to be within certain tolerances. Here is a look at some of the industries that most commonly use thread-ground items.
Aerospace
Making planes and maintenance tools for these flying machines requires a high level of precision. Airplanes hold many lives and need to perform at the highest possible level. Internal grinding for sockets need to fit within a very small error range. Thread grinding with exact measurements can make joints for the attachment of wings, landing gear and a variety of other moving parts. Anywhere two or more pieces are attached with a bolt or screw require threading of some kind.
Medical
Like the aerospace industry, medical professionals and machines need to be in top condition. Internal grinding must be done to a high level of precision to prevent accidents and injury. From things as complex as an MRI to as mundane as a surgical lamp, internal threads keep moving parts within their intended range of motion.
Plastics
Factories and manufacturing lines that use plastic materials need accurately-drilled holes for their molds. These molds will have certain specifications far different from your average screw-hole and could require complex techniques to create. One such example would be a mold with multiple cavities as this would need more than a standard screw to make.
Internal threading is an important part of many industries, such as aerospace, medical and plastics. These industries require accurate threading for safety and proper manufacturing. Having the right size hole promotes less wobble and creates a tight fit, where desired. Local thread grinders may be able to tell you more and whether or not they can provide this service for your company.
