Description

(54) МЕТЧИК(54) METER

рочнение поверхностного сло  с оптимальными параметрами.Optimization of the surface layer.

По мере внедрени  метчика в заготовку вступают в работу следующие зубь  (третий, четвертый и т.д.).As the tap is inserted into the workpiece, the next teeth (third, fourth, etc.) come into operation.

Последний зуб заборной части метчика окончательно формирует резьбовой профиль в детали методом плас .тической деформации. Как только образована резьба на всей длине обрабатываемого отверсти , вывинчивают метчик. Величины деформируемого и нарезаемого, слоев определ ютс  величиной затыловани  ц формой и парамЪтрами заборной части метчика.The last tooth of the intake part of the tap finally forms the threaded profile in the part using the method of plastic deformation. As soon as a thread is formed on the entire length of the hole being machined, the tap is unscrewed. The sizes of the deformable and cut layers are determined by the size of the form and parameters of the intake part of the tap.

Такое конструктивное выполнение метчика обеспечивает повышение качества резьбы.Such constructive performance of the tap provides improved thread quality.
