Mawonekedwe ndi Kusankhidwa Kwa Bits Zoyikira Zolozera

Mawonekedwe ndi kusankha kwa ma index omwe amalowetsamo

Cholowetsa cholozera, chomwe chimatchedwanso shallow hole drill kapena U drill, ndi chida chogwiritsira ntchito pobowola mabowo okhala ndi dzenje lakuya kosakwana katatu. Zakhala zikugwiritsidwa ntchito kwambiri pazida zosiyanasiyana zamakina a CNC, malo opangira makina ndi ma turret lathes m'zaka zaposachedwa. pa. Chobowola nthawi zambiri chimakhala chokwera mopanda malire ndi zolowetsa ziwiri zolozera kuti zipange m'mphepete mwamkati ndi kunja, zomwe zimakonzedwa mkati mwa dzenje (kuphatikiza pakati) ndi kunja kwa dzenje (kuphatikiza khoma la dzenje), monga momwe tawonetsera patebulo lotsatirali. Pamene dzenje lalikulu ndi lalikulu, angapo masamba akhoza kuikidwa.

1. Gulu lazinthu Zoyika zolozera zitha kugawidwa molingana ndi mawonekedwe a tsamba, mawonekedwe a chitoliro, kapangidwe kake, ndi mawonekedwe ake.

(1) Malinga ndi mmene tsambalo lilili, lingagawidwe kukhala quadrangle, makona atatu, diamondi, hexagon, ndi zina zotero.

(2) Malinga ndi chitoliro chodziwika bwino chocheka, chikhoza kugawidwa m'mitundu iwiri: groove yowongoka ndi spiral groove.

(3) Malinga ndi mawonekedwe a kubowola chogwirira, akhoza kugawidwa mu mitundu iwiri: cylindrical chogwirira ndi Morse taper bit.

(4) Malinga ndi kapangidwe kake, itha kugawidwa m'mitundu itatu: mtundu wophatikizika, mtundu wanthawi zonse ndi mutu wodula komanso wodula thupi losiyana ndi kubowola.

2, mawonekedwe azinthu

(1) Yoyenera kudula mwachangu. Pamene Machining zitsulo, kudula liwiro Vc ndi 80 - 120m / min; pamene ❖ kuyanika tsamba, kudula liwiro Vc ndi 150-300m / mphindi, dzuwa kupanga ndi 7-12 nthawi wa muyezo kupindika kubowola.

(2) High processing khalidwe. Pamwamba pa roughness mtengo ukhoza kufika Ra = 3.2 - 6.3 um.

(3) Tsamba likhoza kulembedwa kuti musunge nthawi yothandiza.

(4) Kusweka bwino kwa chip. Gome lothyola chip limagwiritsidwa ntchito pothyola chip, ndipo ntchito yotulutsa chip ndi yabwino.

(5) Kuzizira kwamkati kumatengedwa mkati mwa shank yobowola, ndipo moyo wa bowolo ndi wapamwamba.

(6) Itha kugwiritsidwa ntchito osati pobowola komanso yotopetsa komanso yotopetsa. Nthawi zina, itha kugwiritsidwanso ntchito ngati chida chotembenuza.
