Технологические характеристики растачивания

Растачивание однолезвийным расточным инструментом имеет следующие характеристики::

(1) Адаптивность бурения сильна. Растачивание может осуществляться на основе сверления., литье и ковка отверстий. Широкий диапазон достижимых уровней допусков размеров и значений шероховатости поверхности.;
Except for the small and deep holes, almost all holes of various diameters and structures can be bored, as shown in Table 7-1.

(2) Boring can effectively correct the position error of the original hole. Однако, because the diameter of the boring bar is limited by the hole diameter, its rigidity is generally poor, and it is easy to bend and vibrate. Поэтому, the control of boring quality (especially for elongated holes) is not as convenient as reaming.

(3) The productivity of boring is low. Because boring requires multiple passes with a smaller depth of cut and feed to reduce the bending deformation of the tool bar. Кроме того, boring on boring machines and milling machines requires adjusting the radial position of the boring tool on the tool bar, so the operation is complicated and time-consuming.

(4) Boring is widely used in the hole processing of various parts in single-piece and small-batch production. В массовом производстве, boring the bearing holes of the bracket and box body requires a boring die.
