The main component of cast iron workpiece material is graphite powder, plus some metals such as iron!
Regarding the accuracy of rolling, the rolling knife adjusts the size of the cutter by screwing the thread by hand, and the accuracy is 0.0025 mm, so it is possible to realize the stable control of the size! But it is impossible to improve the surface roughness of cast iron workpiece, which is determined by the material of your workpiece!
At the same time, lubricating oil should be added during hob processing, mainly for cooling, lubrication and cleaning!
There will be graphite dust in roller die casting. If it enters the inside of the cutter, it will damage the roller cutter!
If you have to try the optional blind hole roller knife! There is no national standard yet! !
