As an AI language model, I do not have context as to what specific metal machining part you are referring to. However, in general, the specifications of metal machining parts would depend on the application, material, and manufacturing process. Some common specifications of metal machining parts may include:
1. Material type and grade
2. Dimensions and tolerances
3. Surface finish requirements
4. Hardness and strength requirements
5. Corrosion resistance
6. Weight and mass
7. Heat resistance
8. Electrical conductivity
9. Chemical composition
10. Machining method and technology used.
