Proceskenmerken van saai

Kotteren met één snijkant heeft de volgende kenmerken:

(1) Het aanpassingsvermogen van saai is sterk. Boren kan worden uitgevoerd op basis van boren, gaten gieten en smeden. Een breed scala aan haalbare maattoleranties en oppervlakteruwheidswaarden;
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. Echter, 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. Daarom, 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. In aanvulling, 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. Bij massaproductie, boring the bearing holes of the bracket and box body requires a boring die.
