VA Case Study::Implementation (header processing) rolling in (rolling processing) cutting processing heading

before
  【Problems in all cutting】
Production volume does not increase.
Surface accuracy in the hole is not out, additional work was required.
 


圧造

after
  【Improvement heading to processing (header processing)】
Significant mass production became possible.
Order to produce a mold, precision is stable.
Strength went up by work hardening.
It became a significant cost reduction.



VA Case Study:Implementation (header processing) rolling in (rolling processing) cutting processing heading

before
  【Problems in all cutting】
Quantity does not increase.
Cutting margin is more, it is costly.
 


圧造

after
  【Improvement heading to processing (header processing)】
The long tapered portion, which has been conventionally difficult to be processed in the heading.
I succeeded in mass production in the mold processing.
Significant mass production became possible.
Order to produce a mold, precision is stable.
It is no longer is a waste of material.
It became a significant cost reduction.



VA Case Study:Implementation (header processing) rolling in (rolling processing) cutting processing heading

before
  【Problem】
Because it was cutting all goods, it was minus the head, not the cross head.
For this reason, automation of the assembly could not be.
Since the tolerances of shaft diameter is severe, hange in iron material, were plated.


圧造+転造

after
  【Improvement to (rolling processing) rolling forging and processing (header processing)】
A combination of rolling and machining header processing, change to the cross hole,
Automated assembly of the user has been realized.
And meet the requirements in burnishing the shaft diameter tolerance, it was changed to + iron plating.
I have achieved a significant cost reduction.



VA Case Study:Implementation (header processing) rolling in (rolling processing) cutting processing heading

before
  【Problem】
Handling of the press of the conventional discrete components was done by hand.
Continuous operation for a long period of time is difficult and costly.
There is a risk of injury.

after
  【Improvements to the transport by automatic machine】
We have developed a dedicated automatic transfer machine, to allow continuous operation.
Installed upstream supply device, and the container placed downstream, and also allows continuous operation unattended.
Work efficiency is up, the risk to workers also died.
Cost reduction was achieved by reducing labor costs.

    製品搬送自動化による生産効率改善


VA Case Study:Implementation (header processing) rolling in (rolling processing) cutting processing heading

before
  【Problem】
Material is titanium, and processing in all cutting.
Quantity does not increase, and an increase in cost.
 


圧造+転造+切削

after
  【Improvement to cutting and processing (rolling processing) rolling forging and processing (header processing)】
I was changed to heading + rolling + cutting.
Cutting portion is reduced, the quantity is also now up, I contributed to the cost down.



VA Case Study:Implementation (header processing) rolling in (rolling processing) cutting processing heading

before
  【Problem】
Traditionally, processing of different shaped parts has been difficult in the heading. Therefore, it has been cut.
The increase in cost.
 


圧造

after
  【Improvement heading to processing (header processing)】
The devised transportation, it was possible heading.
Became a cost reduction.



VA Case Study:Implementation (header processing) rolling in (rolling processing) cutting processing heading

before
  【Problem】
Hekusurobu can not be processed at all cutting.
Since the screw portion is short, it is impossible to grip the groove processing.


圧造加工(ヘッダー加工)転造加工(ローリング加工)切削加工にて実現

after
  【Improvement to (rolling processing) heading (header processing), rolling】
I processed the head in the heading.
I will be heading longer threaded portion.
Were successfully automated by chucking the threaded portion.
Then, grab a chuck over again, cutting the length of the screw, we screw processed by rolling.
