一厘 (いちりん) = 1/10 of 1 minute (ichibu) = 0.3175mm
Both refer to the base material used for tapping.
SKS is an alloy tool steel.
・HSS is called high-speed tool steel.
The main difference between the two is the difference in high-temperature hardness.
In contrast to the cutting heat generated during tapping, HSS has a high high-temperature hardness even when the temperature rise
What kind of tap is Synchro Tap?
A synchro tap is a tap dedicated to a machine (also called synchronous, rigid, or direct) equipped with a complete lead feed mechanism that can accurately send one lead per revolution.
General-purpose taps have a margin on the outer periphery to ensure "self-guidance" during processing by the tap itself.
With a synchro tap
In addition, the actual tap product will display OH accuracy or RH accuracy.
In terms of OH accuracy, if one number goes up, how much will it be oversized?
P0.6 or less is 15 μm, and P0.7 or more is 20 μm.
In forming tap , it is 12.7 μm over. ( In forming tap , the expression of tap precision is RH precision.) )
Currently, the standard tap accuracy for aiming
What is the part with food?
The bite part is the name of a part of the tap, and the tip is shaped like a diagonal tip.
This part bites into the workpiece and processes the screw while cutting or raising it.
In the case of hand taps, #1, #2, and #3 are displayed on the case to indicate the length of the bite.
There is no indication of this on the actual product. The
New Roll Tap (NRT) and High Roll Tap (HRT) are both forming tap
While HRT is a rolled-finish tap with basic performance and is limited to sizes of M6 or less, NRT is a grinding-finished tap with a wide variety of tool base material , various coatings, application-specific specifications, and small diamet
