The reasons for the poor surface finish in titanium alloy component machining involve material characteristics, cutting parameters, grinding wheel selection, and various other factors during the processing. To improve surface finish, it is necessary to comprehensively consider these factors and take corresponding measures for optimization. The following aspects are involved:

Characteristics of Titanium Alloy Material:
The structure of titanium alloy material is relatively complex, and the material has high affinity. Atoms in the crystal lattice do not easily脱离 their original balanced positions. This causes the temperature to rise too rapidly during the cutting process, leading to accelerated tool wear, which in turn affects the surface finish.

Selection of Cutting Parameters:
The choice of cutting parameters, such as cutting speed, cutting depth, machine tool vibration, and feed rate, also affects the surface finish. Inappropriate parameters may cause vibration phenomena, leading to part deformation and consequently affecting surface quality.

Selection of Grinding Wheel:
During the grinding process, selecting an appropriate grinding wheel is crucial for surface finish. For example, the medium grain size and medium hardness of silicon carbide grinding wheels, as well as appropriate surface speed, may all impact surface finish.

Other Issues During Processing:
Problems such as over-etching, ash accumulation, striped spots, and incomplete removal of oxide scale may also lead to reduced surface finish in titanium alloy component machining.
