■采用阶段法按13μm的公差幅度对标准有效直径设定精度等级。

■挤压丝锥系列的标准库存品可满足前JIS 2级内螺纹精度的要求。

■挤压内螺纹时，依被切削材质及切削条件不同，有时需要改变

丝锥的精度等级。

■可根据您的不同需求，制作标准库存品以外精度等级的丝锥。

■Tap limit of TAFLET is indicated by class number.

■The limits are established by increments of 13μm.

■Stocked sizes of TAFLET satisfy previous JIS 2 grade precision.

■You may change Tap limit to satisfy the precision because minor diameter is

　changed by tapping condition or work material.

■Tap limit does not guarantee thread limit for the internal thread after tapping.

底孔径咬合率

Percentage of thread engagement per diameter of prepared hole

● 内螺纹的挤压成形取决于被削材和切削条件等。上表中的底孔径作为参考。

● 底孔有弯曲、倾斜、中心位移等场合，易发生内螺纹精度不良和工具损伤等情况。请注意底孔的精度。

● The forming of the internal threads varies depending on the work material and tapping conditions. Use the diameter of prepared hole in the above table as a guide.

● If the prepared hole is bent, wavy, or misaligned, the internal threads may be inaccurate or the tool may be damaged. Pay attention to the accuracy of the prepared hole.

■ 丝锥精度不能保证内螺纹精度。

■ NACHI R grade indicates the accuracy grade of the effective diameter of the forming tap.

■ For the accuracy grade, the tolerance range is set step by step with respect to the standard effective diameter.

■ NACHI REG precision expresses REG:REGULAR as grade satisfies internal thread precision of previous JIS 2 grade or over.

■ Tap accuracy does not guarantee internal threads accuracy.

底孔径咬合率

Percentage of thread engagement per diameter of prepared hole

● 内螺纹的挤压成形取决于被削材和切削条件等。上表中的底孔径作为参考。

● 底孔有弯曲、倾斜、中心位移等场合，易发生内螺纹精度不良和工具损伤等情况。请注意底孔的精度。

● The forming of the internal threads varies depending on the work material and tapping conditions. Use the diameter of prepared hole in the above table as a guide.

● If the prepared hole is bent, wavy, or misaligned, the internal threads may be inaccurate or the tool may be damaged. Pay attention to the accuracy of the prepared hole.

■ NACHI R级表示挤压丝锥的有效直径的精度等级。

■ 精度等级是对应基准有效径设定的阶梯精度公差范围。

■ NACHI REG精度是前JIS2级等同或同等以上内螺纹精度得到的等级，作为REG（REGULAR的缩写）

■ 丝锥精度不能保证内螺纹精度。

■ NACHI R grade indicates the accuracy grade of the effective diameter of the forming tap.

■ For the accuracy grade, the tolerance range is set step by step with respect to the standard effective diameter.

■ NACHI REG precision expresses REG:REGULAR as grade satisfies internal thread precision of previous JIS 2 grade or over.

■ Tap accuracy does not guarantee internal threads accuracy.
