Dear all,The difference in temperature between day and night gradually increased,
and it was time to feel the arrival of winter little by little.
Speaking of autumn, it is colored leaves. In recent years,
due to global warming, there are many areas where November isthe best time to see the autumn leaves.
Why don't you go and see the autumn leaves with your friends and family? 
By the way, thanks to you, Conic celebrated its 43rd anniversary on the 27th of this month! Thank you very much for your support and cooperation.
We are looking forward to continuing our business relationship!
This time, I will tell you about “Shichi-go-san” that is a Japanese traditional ceremony for children. “SHICHI-GO-SAN” (Standing for the ages of seven, five and three)
Shichi-go-san (standing for the ages of seven, five and three) isa traditional Japanese ceremony celebrating the growth of children
and wishing for their continued good health.
Girls celebrate when they’re three and seven years old,and boys celebrate at three and five years old.
Families all dress in kimonos for the Shichi-go-san ceremony
at the local shrine. At the shrine, the chief priest prays for eachchild’s healthy growth.
And when visiting the shrine for Shichi-go-san, you may receivea slender red and white stick-shaped candy called “Chitose ame”.
"Chitose" literally means one-thousand years, and this traditional candy
signifies a long life for the child. All children look forward to receiving“Chitose ame” very much. -------------------------------------------------------------------------------------------------------------------TOOL FOR THICK PLATE PUNCHING

Strengthen thecutting edge withexclusive design!

When punching thick plate, an exclusive designed tool withincreased cutting edge strength is effective to prevent problems
such as punch edge breakage!!

You can choose the punch
material. (D2 / M2)

POINT!

Guide has an easy to insert
taper.

POINT!

The guide hole firmly holds
the punch edge.

The die can be designed toshorten the effective blade
length and prevent
clogging of slug purring.

The second stage of thecutting edge is designed tobe thick to prevent it frombreaking.

POINT!

POINT!

Design the effective blade
length as short as possible.
It is also possible to design
the shortest blade lengthwith zero-grinding margin.
Please ask us about thepresence or absence of theblade tip taper.

1. We accept exclusive design. Please specify the processing conditions (plate thickness, material, etc.).
In addition to square and rectangle punches, round punches can also be manufactured. (It is also
recommended for Hot rolled steel T = 9 punch edge φ6, etc.)
2. This tool is not guaranteed to be “never broken”. In design, this tool incorporates measures to make it hardto break.
 Normally, for stable machining, a punch blade width (short width) of 1 or more times the platethickness for Mild steel and 2 or more times for stainless steel is required.

THE TOOL FOR THICK PLATE PUNCHING (* 1)
CAN BE USED IN THIS WAY!
(*1) Order tool designed based on meeting various conditions.

ADVANCED

You can also use it like this!

In the case of thin plates, it is common to form the workpiece into acylindrical shape with a burring tool and ensure the thickness of the numberof threads. However, in the case of thick plates, burring may be difficult.

Tool used in this test
PROTECH3 1-1/4”
Standard round set φ3.3 C = 0.3

After punching

Direct tapping
without burring

POINT!
By processing the clearance with minimal conditions,

C=1.3
There is almost nostraight part

C=0.3
There is enoughstraight part

(Usually, calculated asuitable clearance)(This experimentalclearance)

the taper of cutting and breaking is reduced on thepunched hole diameter, and a straight part for tapping
directly on the workpiece is secured.
