Introducing product examples of gauges widely used for measuring products with various inner diameter standards.
We would like to introduce a product case of the "Expandable Mandrel" from Ito Precision Tool Manufacturing. This gauge is widely used for measuring products with various inner diameter standards. It is mainly used for inspecting and measuring gear runout, tooth profile, balance, pitch, and hob cutters. This product is called "expandable" because it can measure an expansion range of up to 25mm with a single unit, thanks to its inclined expansion principle. For the measurement method, simply insert the workpiece into the jaws of the mandrel and lightly tap the end face with a soft hammer to complete the operation. It can be used with all inspection machines if it is of the dual center type. 【Product Attributes (Specifications)】 ■ Product Classification: Gears ■ Industry: Automotive, Medical ■ Material: Aluminum, Stainless Steel ■ Measurement Items: Gear runout, etc. *For more details, please refer to the PDF document or feel free to contact us.
