Pre-turned steel parts: BLANKS
Areolas. Areolas.
This is our solution to reducing the high costs of steel and lathe machining of forgings.
These are pre-turned steel parts, after rough turning on vertical and horizontal lathes. We deliver semi-parts with only 3mm allowance.

Benefits of using rough turning parts: shells and bores
Large steel parts are most often made from forgings, whose irregular surface requires roughing at very slow feeds. This generates high production costs.
In the case of shells and lathings, such a cost does not arise, it is possible to perform a quick turning process. In the case of rolled forgings, the process is simpler, but their price is higher.

Competitive steel price
The price of steel for sheaths and borings is still lower than that of locally purchased steel products, even when long-distance transportation costs are added.

Roughing included in the price
We perform the roughing process, which allows us to save time and money – approx. 30% of the cost of turning.

Allowance max 3mm
The shells have a 3mm allowance layer, which can be easily removed on a regular lathe and the part given its final dimensions.

What parts can be produced from blanks and how to size them
We supply steel shells and borings from which rings, shafts, sleeves, rollers, eccentrics and many other products can be produced.
Below we present sample details ( these are not the maximum available dimensions ) and the recommended dimensioning method.
Dimensions include 3mm allowance for surrounds.

Transport and packaging
The casings and the rolls are prepared for sea and road transport. They are stored in wooden boxes, covered with a layer of grease and wrapped in protective foil.
The method of protection allows the elements to be stored for a long time, and thanks to appropriate impregnation, the casing and the fillet do not rust.
