The hole is usually matched with a moving journal or piston and other parts, mainly to support and guide the role. So, how to measure the size of hole parts?
    Hole detection method:
    1The hole of finished product production - smooth limit gauge detection
    2Medium and low precision holes - vernier calipers, inner micrometers, lever micrometers, etc., for absolute measurement

    3, high precision hole - mechanical comparator,aerometer, universal length measuring instrument or inductance micrometer measurement

    As a precision parts size pneumatic measurement equipment manufacturers, focusing on micro-precision, R & D and production of digital display pneumatic momentum meter, a variety of models, quality assurance, manufacturers direct sales, price concessions. Compared with the traditional electronic column measuring instrument, the digital display gas momentum meter has significant advantages.
