Why not just the surface of a ceramic lathe
It is suitable for machining various internal and outer surface. The machining precision range is IT13 ~ IT6, the surface roughness Ra is 12.5 ~ 1.6. (2) the structure of the tool is simple and easy to make, making it easy to make reasonable choices according to the processing requirement. It is also convenient to grind and remove the blade
The structure, material and production of the pieces are more adaptable and widely used. In addition to cutting various kinds of steel, cast iron and non-ferrous metal, it can also be used for turning glass, rubber, nylon and other non-metal. For some not suitable for grinding non-ferrous metal diamond tool can be used for fine turning, can obtain high machining accuracy and small surface roughness values. (4) in addition to the allowance for rough surface uneven, the vast majority of turning for cutting cross section such as continuous cutting, therefore, the change of cutting force is small, smooth cutting process, is good for high speed cutting and strong cutting, high production efficiency.
Ceramic knife has the very high hardness, suitable for machining hardened workpiece, if you are used to turning the following HB300 artifacts, effect is not ideal, and it is a huge waste. 2. Ceramic cutting tool generally has a lot to rake Angle grinding, that is very sharp, and ultra-high hardness is accompanied by high brittleness, thus should maintain high cutting speed and small cutting depth, such as turning diameter of 50, HB300-350, I will choose the rotating speed of 1000-1200, fine car allowance of 0.08-0.2, 0.05 0.1, feed surface quality should be no less than grinding. 3. Usually in the sense of turning processing (with ceramic cutting tool), the surface roughness can reach 1.6 and 0.4, but it is not able to completely replace grinding, for mechanical precision lathe relative to grinding machine is not an order of magnitude, processing of the workpiece in shape and position accuracy is not too good. So, be able to do not grind the car to make, the mill still must grind, cannot be lazy. I can only say so much, I hope I can help you.
How much is your allowance? And what materials are you working on? Is it ceramic or metal? Ceramic machining hardening materials of high hardness in general. Main processing easy car iron metal ceramics, such as 45 # fine car. Your car is not light could be less allowance leave, should be in 15 to 30 or so.
