高硬度鋼用底刃付きスレッドミル　at-2とは？ | オーエスジー

What is the thread mill AT-2 with end cutting edge for high-hardness steel?

It is a thread mill with end cutting edge for high-hardness steel.

Helical drilling and threading can be performed simultaneously in a single unit.

In the processing of screws on high-hardness materials, it is effective in solving the problems faced by customers.

 

Example of a tool for drilling and screwing more than 50 HRC

High-hardness processing is already greatly affected by instability.
Depending on the machine specifications, there is a range of conditions that we are not good at.
If the workpiece is removed, even a slight shift in the center will cause instability during machining.

New proposal: Simultaneous processing of helical drilling + threading
Thread Mill with end cutting edge for High Hardness Steel AT-2
A thread mill is a tool that uses helical machining of a machining center to perform thread machining.
By simultaneously drilling + threading, stable machining with reduced risk is achieved even for high-hardness steels that are difficult to process.

No pilot holes required

 

 

Advantages of pilot hole machining and threading at the same time

 

・Improvement of setup

There is no need to prepare a separate machining environment that should be prepared, such as a machine that is good at the recommended condition range and a suitable cutting oil.

All you need to do is prepare the range of conditions in the AT-2 condition table and the cutting oil (or air blow ).

・Since pilot holes and threads are processed at the same time, there is no risk of instability due to phase shift, such as removing the workpiece.

・Since the chips are also finely divided, the risk of sudden breakage can be suppressed.

・Tools can also be consolidated into one.

 

AT-2 for high-hardness steel: Specifications for high hardness

Dedicated to internal thread processing ( external thread cannot be processed)

The combination of these makes it possible to stably perform thread machining that requires harsh high-hardness materials and strict dimensions.

 

In addition to metric screws, tapered threads for pipes are also on sale.
