1, the production of supporting. Line tap grinding with thread grinding steel wheel, or buy SB725F singlet grinding wheel. If the processing of non-standard, or low-volume, multi-specification production, it is recommended to select the adjustment convenient CNC tap grinding.
2, the type of tap. Straight Fluted Taps all Taps mill no problem. Processing spiral flute taps, taper pipe tap, squeeze the other types of taps, L tap to choose the correct model. If you tap the cut-off type complex
Like a round dome, trapezoidal, etc., then use the two-dimensional CNC dresser.
3, the production efficiency and accuracy. The multi-line tap grinding efficiency is the single-wire tap grinder 2-3 times, but the single-diamond pen trim the teeth more accurate than the effect of multi-wire steel wheel trim. Diamond line roller is the ideal.Think, the cut-off type efficiency and stability of high, but the price is not thin. To improve the accuracy of closed-loop system can be used, tap the pitch and cut precision can be increased one. Select the open-loop or closed loop is also very important.
4, the size of the processed tap. Tap medium and small sub three categories, M12 The following is a small tap, count medium-sized M12-M50, the M50 more than tap. The manufacturers for different range of development tools. Small tap grinding body

Small size, high efficiency, medium tap grinding to ensure that the machine strength, and efficient. Large tap, because the yield is low, generally universal thread grinding will be able to perform competently. In addition, the national standard on the M6 following tap did not even Grinding

Demand, but to get a good tap, tap of the M1 had to take relief grinding.
