Ki jan yo rezoud pwoblèm nan deformation pwosesis nan presizyon wonn asye ba

Anvan pwosesis la, asye a se izotèmikman rkwit (tankou 860 degre austenitization + 650 degre izotèrmik transfòmasyon) nan rafine grenn yo pèl nan mwens pase 10μM, ak estrès la rezidyèl ka redwi a mwens pase 80MPA, redwi a (50MPA, redwi a (50MPA, yo ka redwi a. Adopte spheroidizing rkwir fè karbid yo esferik ak diminye rezistans a nan deformation plastik pandan koupe . apre pwosesis ki graj, estrès sekou rkwir (550 degre × 3H) se ranje yo lage koupe estrès . MM-MM-MM/FINISHING ALWODANS {{{ yon sèl-fwa koupe konsantrasyon estrès .

When cutting, carbide tools (such as YW1 brand) with a rake angle of 10°-15° and a main deflection angle of 75° are used to reduce radial cutting force by more than 30%; BTA drill + 20MPa high-pressure cooling is used for deep hole processing to reduce drill bit deflection. The slender shaft (length-to-diameter ratio>15) sèvi ak yon ankadreman sant + yon ankadreman disip pou sipò jwenti, ak pwen sipò mete chak 150-200 mm, epi li se Runout radial kontwole nan 0 . 005mm; Pati mens-miray ranpa yo sèvi ak enstalasyon plastik likid, respire presyon (presyon mwens pase oswa egal a 5MPa), ak deformation nan blocage ka mwens pase 0.002mm.

Rail yo Gid zouti machin yo modènize nan BEARING<5μm). Precision machining needs to be carried out in a constant temperature environment of 20±0.5℃. The lead screw is equipped with a grating scale closed-loop feedback (resolution 1nm), and the thermal deformation error is ≤0.001mm/m. After machining, the size can be further stabilized by low-temperature aging (120℃×24h) or shot peening (forming a 0.2-0.3mm compressive stress layer) to ensure that the deformation is controlled within the tolerance of 1/3 (such as φ50h6 shaft diameter deformation ≤0.003mm).
