Unequalled Flute Variable Helix Carbide End Milll For Titanium Alloy Wroking
Unequalled Helix Carbide EndMilll for Titanium Alloy
Titanium metal is difficult to process materials, and its main processing characteristics are as follows;
A, cut blade load heavy
It is mainly because its cutting deformation coefficient is small when processing titanium alloy, and the cutting force is concentrated near the cutting blade, which is easy to cause crash.
B. High cutting temperature
The titanium alloy is different, and the temperature of the cutting area is about twice as high as 45 steel.
C. Severe wear tools
Titanium is more active, and it is easy to form a hard and crispy expression with oxygen and nitrogen, which exacerbates the wear of the tool.
D, the rear knife surface friction is large
Selection of processing titanium alloy milling cutters and tools
Machining titanium alloy generally chooses hard alloy rods, such as tungsten cobalt hard alloys, and typical brands are YG8 and YG6X; when choosing a hard alloy titanium alloy knife, tungsten titanium or TIC and Tin should not be selected. Coating knife.
Secondly, processing titanium alloy knives can also choose cobalt -containing high -speed steel, aluminum or high -speed steel. However, the production efficiency of high -speed steel tool processing titanium alloy is low and easy to wear.
When processing titanium alloys, a smaller front angle should be selected, which can significantly improve the strength and anti -collapse ability of the cutting blade; choose a larger rear corner to reduce the contact area of the rear and transition surface and the processing surface of the processing. At the same time, the cutting speed of the tool can be moderately reduced, the amount of knife can be enlarged, and the amount of feed should be appropriate;
Cutting parameters of processing titanium alloy milling cutter (hard alloy);
Milling the skin; the milling speed is 18 ~ 24m/min, the amount per teeton is 0.10 ~ 0.15mm/z;
Rough milling; milling speed 36 ~ 48m/min, percentage of 0.10 ~ 0.15mm/Z, 1 ~ 4/mm side of the knife;
Square milling; milling speed of 38 ~ 70m/min, the amount per teeton is 0.04 ~ 0.08mm/Z, and the amount of knife is 0.5/mm on the side;
Secondly, when processing titanium alloys, you can choose to cut with water -based cutting fluid or no cutting fluid. Do not use fluorine -containing cutting fluid, not suitable for contact with aluminum, zinc, copper, tin, and its alloy
