Overall length is the total length of the tungsten carbide router bit between the two ends. Specially, the bit will typically go into the collet 1 inches or more, so during the actual practice the length of the bit that actually out of the collet should be taken into consideration.  


Chip load refers to the thickness of a chip which is formed in the material machining processes. Chip load plays a vital part, as the proper chip size will remove the hear and promote long tool life. If the chip is too small, heat is transferred to the cutting tool causing premature bit failure. Too high of a chip load will cause poor edge finish, and transfer cutting load or thrust to the part, possibly causing it to move. And when a cut is finished, the recommended operation condition is room temperature .

When people find tungsten trioxide film material has electrochromic properties, then they carried out extensive studies at electrochromic, photochromic Gaschromic discoloration film, and powder preparation and so on. What’s more it has achieved many fruitful results. Electrochromic material refers to a specific material be applied at a certain voltage and electric filed, the material’s color or transmittance will cause reversibly changes phenomenon. Amorphous tungsten trioxide film having high coloring efficiency, good reversibility, short response time, long useful life, low cost, coloring and fading ‘s optical change range wide and other advantages so it is considered to be the one of most promising electroluminescent material. WO3 electrochromic process is generally represented by the following formula: WO3 (transparent) + x (M ++ e-) ← → MxW6 + (1-x) W5 + xO3 (blue). The M + = H +, Li +, Na +, 0 <x≤1, e- is an electron. When the electron and ion implant into transparent WO3 film, the film was blue. When the ions and electrons are extracted, transparent films returns to its original state. This is due to partly +6valence of W6 + is reduced to +5 valence of + W5 which produce tungsten bronze MxWO3.

Precipitation method includes co-precipitation method and chemical precipitation method. Using precipitation method produce nano tungsten trioxide there will get a smaller powders particle diameter and more uniformity than using ammonium paratungstate producing tungsten trioxide powder. Prepared process as follows: First, mixing 1ml / L of Na2WO4 solution and Na2SnO4 solution then dropped this solution into boiling dilute H2SO4 with slowly, in this process should stirring constantly. Then aging, washing, filtering, drying and calcining to obtain SnO2-WO3 gas sensing powder materials. When doped 5% SnO2 additive can inhibit WO3 crystal grains to the growth and also can increase its gas sensing degree. Using chemical precipitation method to produce nano tungsten trioxide there is the process: Firstly, weighed 3.0g Na2WO3 and 0.005g one hundred and sixty thousand trimethyl ammonium bromides (CTAB) then make them dissolved in 10ml of distilled water. Then take 3ml solution dropwise adding to 5ml 3mol • HCL L-1with slowly. The solution was stirred for 1 to 2 hours after centrifugation the precipitate. With distilled water and acetone repeatedly washed it, and the resulting precipitate was placed in an oven at 80 ℃ dried to obtain precursor. Finally, the precursor was placed 300 ℃ muffle furnace, to obtain a nano tungsten trioxide.

Due to its high density, excellent absorption behaviour against radiation and environmental friendly characteristics, tungsten alloy can be widely used in radiosurgery tungsten alloy shielding.Radiosurgery is surgery using radiation,that is the destruction of precisely selected areas of tissue using ionizing radiation with tungsten alloy shielding rather than excision with a blade.

Radiosurgery tungsten alloy shielding is usually used to treat cancer.Radiosurgery tungsten alloy shielding is usually in stereotactic radiosurgery (SRS), the wordstereotactic refers to a three-dimensional coordinate system that enables accurate correlation of a virtual target seen in the patient's diagnostic images with the actual target position in the patient anatomy.
