Titanium alloy precision machinery parts processing characteristics and the process improvement of titanium alloy is a kind of high strength, good heat resistance and corrosion resistance of materials.
Its in damp environment, its corrosion resistance is far better than stainless steel material, widely used in precision aircraft engine compressor components.
Each material has its characteristics, then in precision machining
, the machining titanium alloy have some characteristics, what problems will meet again?
In when the force is committed to precision machining of 15 years, processing this kind of parts, especially thin disc ring kind of precision machinery parts processing, basically has the following three aspects: first is the deformation, stress especially reinforced slot for thin wall structure in various places, if improper clamping force or jig location selection, are easy to make the parts precision machining process of deformation, thus affecting the workpiece dimensional accuracy and shape accuracy;
Followed by the thermal deformation: titanium alloy material thermal conductivity is relatively poor, if local heat cutting is not timely send out, will cause thermal deformation after precision machinery parts processing, resulting in parts size is out of control;
The third is the vibration deformation: the cutting force (
Especially the radial cutting force)
Vibration, impact, it is easy to size accuracy, precision machining parts, precision and surface roughness.
Titanium alloy precision parts
machining parameter selection principle is: rough machining, give priority to in order to improve the productivity, considering efficiency and processing cost;
Semi-finishing and finish machining, should be in guaranteeing precision machinery parts processing precision, surface roughness and machining quality under the premise of both cutting efficiency, production efficiency and processing cost, make the cutting tool and machine tool cutting effect.
Turning is proportional to the cutter diameter, commonly is inversely proportional to the cutting depth.
In the actual machining process, can pass for the cutting tool, the voice visual tools and precision parts material cutting condition and so on, timely adjust process, processing way can be divided into two kinds of, shun milling and inverse milling.
Considering the relative movement between the coefficient of friction, the driving part clearance, movement of inertia and the relationship between damping ratio and can climb milling machining method to improve the efficiency of precision machining.
