CNC車床加工裝夾時的注意事項

數控車床的加工流程與一般車床相似. 然而, 因為CNC車床是一次性裝夾的, 連續自動加工完成所有車削工序. 所以, 應注意以下幾個方面:
1. 合理選擇切削量
切削參數的選擇是否 (美聯社, F, v) 是合理的, 對於工具機能否充分發揮工具機的潛力和刀具的切削性能以達到高品質起著非常重要的作用, 高產, 成本低、運作安全.
粗車削時, 首先考慮選擇盡可能大的車削深度ap, 再選擇較大的進給量f, and finally determining an appropriate cutting speed v. Increasing the turning depth ap can reduce the number of passes, and increasing the feed f is beneficial to chip breaking. 所以, it is beneficial to select the rough turning amount according to the above principles to improve production efficiency, reduce tool consumption, and reduce processing costs.

CNC車床裝夾設計

精車時, the machining accuracy and surface roughness are required to be high, and the machining allowance is not large and more uniform. 所以, when choosing the amount of cutting for finishing, it is important to consider how to ensure the quality of the machining, and on this basis, maximize the productivity. 所以, a smaller (but not too small) turning thickness ap and feed f should be used for fine turning. 並選擇高切削性能的刀具材料和合理的幾何參數，盡可能提高切削速度v.

2. 合理選擇工具
1) 粗車削時, 選擇強度高、耐用度好的刀具，滿足粗車時大車深、大進給的要求;
2) 完成車削時, 選擇精度高、耐用性好的刀具，確保加工精度的要求.
3) 為了減少換刀時間，方便對刀, 機夾刀片應盡可能使用.

3. 合理選擇燈具
1) 盡量使用通用夾具來裝夾工件, 避免使用特殊固定裝置;
2) 零件定位基準重合，減少定位誤差.

4. 確定加工軌跡
The processing route is the movement track and direction of the tool relative to the part during the processing of the index-controlled machine tool:
1) It should be able to ensure the processing accuracy and surface roughness requirements;
2) The processing route should be shortened as much as possible to reduce the tool idle travel time.

5. The relationship between machining track and machining allowance
現在, under the condition that the CNC lathe has not reached the popular use, the excess margin on the blank, especially the margin containing the forged and cast hard skin layer, should be arranged on the ordinary lathe for processing. If you must use a CNC lathe to process, you need to pay attention to the flexible design of the program.

6. Jig mounting points. 現在, 液壓卡盤與液壓夾緊油缸的連接是透過拉桿實現的. 液壓卡盤夾緊要點如下:
首先用活動手拆下液壓缸上的螺母, 拆下拉管, 並將其從主軸後部拉出, 然後用移動手旋下卡盤固定螺絲，即可取下卡盤.
