CNC lathe manufacturers DESCRIPTION Speed ​​and Feed unreasonable amount of tap breakage caused
    When processing problems, the majority of domestic users is to reduce the cutting speed and feed rate is reduced, so that efforts to promote tap lower thread precision of its production is thus considerably reduced, which increases the surface roughness of the thread, the thread threaded aperture and precision are impossible to control, of course, inevitable glitches and other problems. However, the feed rate is too fast, resulting in excessive torque can easily lead to broken tap. Attack when cutting machines, usually steel material is 6-15m / min; quenched and tempered steel or hard steel material is 5-10m / min; stainless steel 2-7m / min; cast iron 8-10m / min. When the same material, whichever is the higher value of small diameter tap, tap diameter whichever is lower.
    Operator technique and skills did not meet the requirements: more of these problems, we need to make a judgment or operator feedback to the technician, but the vast majority of domestic operators inadequate attention. For example, when machining a blind hole threads, when the tap is about the moment of contact hole bottom, the operator did not realize, based upon the tapping speed yet reached the bottom of the hole when the feed, or poor chip forced to tap into the lead break . Proposed operators to strengthen accountability.
    The scrapping of expensive components and then had to be scrapped, substandard products into the defective had to throw away. Thus, large-scale enterprises to large, expensive, precision machining of workpieces, even spend the high price of imported taps are not made in China, because once broken taps, scrapped parts, the cost is considerable.
