How do you sharpen a cast-iron tool?
The tool should be chosen well, at least with YG6, the fine car is YG3. 2) the car knife takes the Angle of 0, the big cut open the rough and the negative Angle. The big round lone blade.
It's best to use YG, not at hand, YT5, YT15, and also able. Angle of knife: the front Angle can be worn 20 degrees - 25 degrees, a shallow and wide arc grooved. It is always important to pick 5 degrees of the blade. The rear Angle is 6 degrees -- 8 degrees, negative Angle 6 degrees -- 8 degrees. On the edge of the blade, you can grind a minus 5 degree negative, and the width of the blade is 0.2 to 0.4. The main deflection is 90-75 degrees for processing conditions. (this dao t = 3 -- 7mm, s = 0.3 -- 0.6 mm/n turns v = 50 -- 100 meters per minute.) the effect is good, and the chip does not splash.

The Turning tool is a tool for Turning the machine with a cutting part. Main job is to produce and processing part of the chip, including the blade, the structure of the chip broken broken or volume approach, chip removal, or let store the space of the chip, cutting fluid channel such as structural elements.
