Accuracy, conditions and proper cutting parameters

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.

Titanium pipe in water purification Role

The main characteristics of titanium tubes for desalination:
Density, specific strength (strength / specific gravity) is high density metallic titanium 4.51g / cm3, higher than Al and less than steel, copper, nickel. The intensity ratio of the first metal but is located, is a stainless steel three times, 1.3 times the aluminum alloy;
Good corrosion resistance ) Titanium is a very reactive metal, which is very low equilibrium potential, thermodynamic corrosion tendency in the medium is large. But in fact the titanium is very stable in many media, such as titanium alloy plate in an oxidizing, neutral or weakly reducing medium such as corrosion resistant. This is because the titanium and has a great affinity for oxygen, air or oxygen-containing medium, the titanium surface layer of dense, strong adhesion, large inert oxide film to protect the titanium substrate corrosion. Even due to mechanical wear and tear will heal or regenerate quickly. This shows that titanium is a metal with a strong passive tendencies. Medium temperature below 315 ℃ titanium oxide film 3 is always kept this characteristic, a good heat transfer performance of metallic medical titanium plate, although lower than the thermal conductivity of carbon steel and copper, but the titanium excellent in corrosion resistance, so the wall thickness can be greatly thinned , and the surface of the heat exchanger and steam condensation droplets way, reducing the thermal group, so the surface is not scaling may also reduce the thermal resistance of titanium so that the heat transfer performance improved significantly

4 good heat resistance
The new long-term use titanium spring wire or higher temperature 600 ℃.
Good chemical resistance, low temperature performance as the representative of cryogenic titanium alloy, its strength with decreasing temperature increase, but the plastic change is not large.
Tensile yield strength of its performance close to that of titanium shows its yield ratio (tensile / yield strength) high, indicating that the titanium material difference in molding plastic deformation. Since the ratio of the yield limit of the titanium and the elastic modulus is large, so that resiliency titanium molding large.

titanium alloy plate and stainless steel plate What is the difference

If the titanium alloy plate shows only one kind of chemical elements from titanium composition. Titanium is very light.titanium foil for sale Commonly used in aviation. Medicine. And corrosion-resistant. So the value is more expensive.
Stainless steel is cheaper. Uses are more extensive. Why not rust stainless steel, adding more than 12.5% of chromium in iron and steel-related. Corruption and incompetence in the oxidative corrosion medium, chromium steel surface can quickly generate a dense layer of passivation film to prevent metal matrix is destroyed. When the chromium content above 12.5% ??when forming a dense layer of stable passivation film, rust resistance occurs leap forward in consolidation, the ability to greatly enhance corrosion resistance,titanium standard parts which is why the amount of chromium-containing stainless steels have a 12% For the above reasons.
Commonly used stainless steel 304 chemical elements for 1Cr18Ni9Ti which one seems to refer to the carbon content. Cr18 refers to the content of chromium. Ni9 refers to the nickel content is what you said above Ti titanium titanium alloy plate of the.
