The tool axial and radial runout accuracy is also important. For example, if the blade is not correctly installed in the cutter, the cutter around the cutting edge will quickly damage. When cutting titanium bar for sale, a number of other factors, such as poor tool manufacturing tolerances, wear and tool damage, the handle has a defective or poor quality, spindle wear, etc., will largely affect the tool life. Observations show that in all cases the processing underperforming, 80% are caused by these factors. Although most people prefer the positive geometry tool, but in fact slightly negative rake angle geometry of the tool can be removed with higher feed materials and feed per tooth of up to 0.5mm. But this also means that you must maintain optimal steady state, that the machine should be very strong, and the fixture should be extremely stable.
In addition to the Plunge milling (preferably circular blade) outside, you should try to avoid using 90 main angle, this usually helps to improve the stability and overall performance obtained, when used in shallow depths cut especially in the case, in When deep cavity milling, a recommended practice is to use the tool connected to the handle variable-length tool, rather than using a single length of the long knives in the whole process.
Adjustment of the cutting parameters to overcome lower vibration due to the amount of feed per tooth caused by traditional solution, but this method is not appropriate because it would have catastrophic cutting tool life and influence. Indexable insert cutting edges require a certain amount of rounding to increase the cutting edge strength and better coating adhesion.
When milling titanium bars, at least to the minimum required for tool feed amount of work - usually each tooth 0.1mm. If you throw vibration trend, the blade is damaged or shorten tool life issues will be inevitable. Possible solutions include accurate calculation of the amount of feed per tooth, and make sure it is at least 0.1mm.
It may also be lower spindle speed, in order to achieve the initial feed rate. If you use the smallest amount of feed per tooth, and the spindle speed is not correct, then the impact on the tool life can be as high as 95%. Lower spindle speed usually improves tool life.
Once established stable condition, can be a corresponding increase in spindle speed and feed rate to get the best performance. Another approach is to remove some of the blade from the cutter blade or select containing less cutter.
