定焦鏡頭和對焦環的CNC車削

Analysis of parts processing status As shown in Figure 1, the focusing tube (aluminum part) is processed with a straight arc-shaped wall groove and two spiral wall grooves on a turned cylindrical blank.
Part wall thickness is 4mm, available?
銑刀直接分層銑削溝槽, 但需要利用加工中心附加的第四軸或車削中心的C軸功能來實現. 本文使用的是車削中心工具機. 用簡單的夾具加工後發現聚焦管. 由於溝槽是穿壁加工而成，溝槽形狀較長, 僅使用軸向夾緊, 加工時因裝夾變形而無法保證坡口寬度.

產品分類: Turned Parts
品牌: 代加工
標準: 國家標準
材料: 6061 鋁
寬容: 正負0.01mm, surface oxidation, 無毛刺
規格: 根據要求, 來圖來樣加工定制
介紹: 專業五金配件加工廠

The groove width in the middle section of the straight arc groove can only reach 3.4mm, and the width of 4mm near the two ends of the groove cannot be guaranteed. Although the deformation of the chute is smaller, it cannot meet the size requirements. 因此, the height of the barrel column of the fixed focus lens has changed, and the degree of deformation is proportional to the axial clamping force. If the clamping force is too small, it will also cause relative rotation of the workpiece during milling. This fixture structure is only suitable for circumferential milling of shallow grooves, but not suitable for through-wall groove milling.
