Keyway milling cutter how to process ~ such as how to lower the knife how to cut and so on ~ the more detailed the better how to determine the speed of the line
First with a good grinding center drill a row of points, pay attention to not too deep, and then use smaller than the keyway of the milling cutter to open thick, remove the excess material, and finally use new milling precision milling.
Under the knife, you use a larger tool (I process 3H7 with 2. 5 knives, 10 silk at a time) 50 times at a time. Your knife is tungsten steel or high-speed steel, tungsten steel with a diameter equal to 30000 divided by the speed. High speed steel is divided by 12000 by diameter equal to speed. I'm talking about all the data I see, and it's low carbon steel.
Keyseating slotting cutter diameter of 8 to 16 mm, can be directly on the center line of the axis after direct drilling to drill, the depth after the cross feed, until the required length. The wire speed is about 100 to 120, which is to say the speed of high speed steel milling cutters. If the diameter is small, a knife, it will not work, so that the processing of parts will be large at the end of the small, the width is not easy to guarantee.
