The hottest hard material processing tool

Hard material processing tools
the tools used for hard material processing can use the contour finishing milling cutter f2139 of wxk15 and CBN blades, small modular tools with threaded connections, small modular tools with thermal expansion connections, etc. in addition, there are also integral carbide milling cutters and integral carbide drills made of wxk15 and wxk35, The whole carbide tool coated with thicker CBN (different from the coated CBN with thickness of micron, we call it package CBN)
in order to ensure that when machining hard materials, due to the high strength of the material, the cutting force for the high-performance plastic solution of the battery shell rises sharply, which leads to excessive deformation of the tool bar under the action of huge cutting force (although most of this deformation can be recovered after the cutting force is eliminated), Walter company has developed a new type of contour finishing milling cutter f2139, a small modular tool with threaded connection, The small modular cutters connected by thermal expansion have introduced the structure of integral cemented carbide tool bar
due to the different characteristics of steel and cemented carbide elastic dies, such as convenient operation, reasonable design, simple structure and so on, the degree of deformation between them is very different. We know that the elastic modulus of steel and cemented carbide are: e steel = 210000 n/mm
e cemented carbide = 600000 n/mm
according to the formula: F = f · L/(3 · e · I)
we can see that the deformation of the steel cutter bar is 3.5 times that of the overall cemented carbide
as for the integral milling cutter manufactured by xkw15 and package CBN method, Walter's specifications are as follows:
ball end milling cutter, straight groove 2 teeth, material wxk15, f3-f10
ball end milling cutter, straight groove 2 teeth, material package CBN, f6-f10. First of all, consider whether the installation of the main body of the impact tester is vertical
ball end milling cutter, chute 4 teeth, material wxk15, f3-f10
curved surface milling cutter, straight groove 2 teeth, material wxk15, F6.-f10
surface milling cutter, Straight groove 2 teeth, material package CBN, f is a common experimental machine manufacturer, 6-f10
curved surface milling cutter, chute 4 teeth, material wxk15, f10
and rebig's DCX products, the minimum diameter of ball end milling cutter is 1mm, and the minimum diameter of end milling cutter is 3mm. (end)
