The chip removal operation in threading with a tap seems simpler than operations with other cutting tools. However, removing the chips, lubricating the cutting edges, determining the relationship between speed and feed according to the tap pitch and such facts make tapping a complex operation. The prerequisites (tap selection, cutting conditions, etc.) must be determined in the best way for the tap to be used properly.
There are many parameters in the selection of taps. Cutting tool manufacturers present the features of the taps they produce to the user in tables. The Czech NAREX Zdanice Tap catalog provides easy and clear tabulation how to choose the most suitable tap with optimum cutting parameters. The most important issue after all those selections is the coating of the tap.
Despite the obvious advantages listed below, a quite low ratio of tap use in Turkish industry is coated. Increase in the application of this affordable technology, which increases tool life up to several times with only an extra payment of only small percentage compared to the uncoated tap price, will result in a serious cost reduction in the industry and save time. Apart from selling our products, we support them in choosing the most suitable product for their operations and using this product in the most efficient way. For this reason, in order to encourage the consumption of coated taps, we sell NAREX coated taps with very close price level of uncoated ones.
Advantages of TiN, TiALN, TiCN coats:
- More surface hardness
- Less friction coefficient
- Easier to cut without coolant
- Less coolant consumption
- Easy tapping in high speeds
- Higher wear resistance
- Much longer tool life
- Minimizing production stops caused by tool breakage or wear
- Lower unit cost
In summary, the use of taps TiN or TiALN coating and selecting the correct cutting parameters both extends tool life and provides double-sided economy by increasing tool performance and machining speed. The fact that there is not much difference between the prices of TiN or TiALN coated NAREX taps proves that using NAREX coated taps is the right choice most of the time.
