Cold ring rolling

Cold rolling summary

It repeats various improvement since 1982 to have appeared in the world in a current foundation stone than a longtime study, and the total output exceeds 700 and gets a great evaluation. I make an effort every day without breaking a progress posture based on these results consistently.
CRF takes an initial of COLD ROLLING FORMER and is the machine which let a meaning of the TOP of COLD ROLLING hold TCR. V means version up, and the number expresses the capacity of the machine. OR, IR, UC express the type of the sizing device incorporating.
A machine is the machine which it is cold by mandoreruto molding roll by cylindrical work basically, and rolling molds the inside and the outside as. I make approximately 20% of rolling in outer diameter, and the work expands it. The work had rolling of is had sizing of and drifts from a machine exit. These movement is automatically carried out from the entrance to the exit.
This plane can provide extremely high productivity. The machine is comprised of a body section and an attachment.
With the attachment an oil pressure tank and a rolling oil tank other; put it.
There are entrance Hopper, a palette inversion machine, washing, cooling, an oil skimmer, a centrifugal oil content separation machine, a measurement device as other special accessories.

Guidance of "the top cold rolling machine of NC servo specifications"

A cold roll machine NCRF machine is the top cold rolling machine of NC servo specifications.
In correspondence with complicated work thought to be impossible with the cold roll, I made possible limited production of diversified products, product precision up, large shortening at the preparation spare time.
As well as a V series machine, I can easily set roll forwarding speed, dimensions input, the clearance input with a touch panel monitor and can perform confirmation, the measures of the place by detailed error message smoothly.
I improve operability by the ITEM preservation by monitoring specifications remarkably and it is poor in the work by the data backup function and can perform the confirmation of blank dimensions or the review of the setting number by history confirmation of the processing defectiveness efficiently.
They assume a loader part servo specifications and are the high efficiency machine which performed precision up, the speedup of positioning, but the special specifications to be able to perform extension of the case life, shortening at rolling time are possible without installing an outer diameter measurement unit between sizing from rolling, and performing sizing by the NG work.

Characteristic

In comparison with a usual construction method high efficiency

Materials edible produce largely improves.
20% - 30% improve with the outer ring among others 35% with the pillow bearing outer ring.
Uniform high quality is provided.
METALFLOW which went into an external form form for rolling plasticity processing is provided, and there are few heat-treatment distortions, too. I am provided more than surface roughness ▽▽▽, and it is good for the seal part, and the R or other dimensions become stable orbit, and there is no processing leak.
The life of the tool (roll mandrel) gets longer because it is cold plasticity processing.
The environment in the factory improves. (mist dust does not appear)
There are few costs of equipment and finishes it.
There are few electricity bills and finishes it. (in CRF120 total electricity only 12.7kw)
It is the low noise.
Cycle time is short.
An interval is short at the time of making arrangements.
The processing of the outer ring in the bearing by the cold plasticity is a processing method looked forward to for a production engineer. That is because many advantages are included. I have many features up to large materials edible produce, shortening of the cycle time, reduction, quality of the labor cost particularly metallurgic improvement, production environment.

Security technology

A safe standard is severer than Japan, and, in Europe, a law not to let you import the machines which do not acquire CE marking is established.
The rolling machine of the mutual prosperity delicate work clears all of order, low voltage order, EMC orders at an opportunity and establishes a security technique accepted in the world.
