Processes and manufacturing capabilities

The Stero GmbH offers your product from a single source. Machined or without cutting machined metal parts to additional services such as surfaces, assembly and logistics transactions.

CNC turning
Production lot: 100 - 50,000
Size range: 5 - 65 mm, length 350 mm

All of our CNC lathes are equipped with integrated rear-face machining and driven benenen tools. This with up to 11 axes equipped machines have also partly on B + Y axes.Therefore, we are able to completely restore even the most complex turned parts with low tooling costs without further post-processing

Curve knitted Euere lathes
Production lot: 50 - 1 million units
Size range: 1 - 36 mm, length up to 1000 mm

Turned parts with mild to moderate difficulty are made on our cam-controlled automatic lathes. Thread milling and Polygon are made in addition to the normal turning.

Plain turning
Production lot: 100 - 50000 pieces
Size range 5-26 mm, length up to 280 mm


In the long range of rotation, our machines are also equipped with integrated rear-face machining, driven tools and Y axis.

Mill
Our CNC machining centers with pallet changer and 4 Axes equipped. Changes to both the rotating parts from our own production as well as the use of components of our customers.

Processing examples:

Post-processing of Kokillengußartikeln
Post by diecast parts
Post-processing of cold formed parts

We manufacture from individual parts to complete machines.

Above all devices, equipment and small series (bis. about 500 pieces). Competent and with great experience, we work every day creative solutions to clients at home and abroad.

We like to go unconventional paths.

Not just on principle. From experience we know that often just lead them to the goal. We see complex and unusual tasks as challenges, which are particularly exciting. And on whose solution we are really proud of.

Down to the smallest detail.

Precision Machined develop, manufacture, we measure and assemble for you machines, devices and components - because they can look very closely.

What can we do FOR YOU?

Basically EVERYTHING that you need for making your products or even the product itself:

Machines, devices, assemblies or just items: After our design or customers, including functional test and acceptance report (mechanics)

from small parts to large part
Small parts min.3 x 3 x 3 mm and up to 0.3 g
Large parts max. 8000 x 2000 x 1000 mm and up to 6000 Kg
Even "problem parts" of lot size from 1 to 200

CNC turning and milling parts in 4 - and 5 - axis machining or multi-sided machining in one clamping position. For everyone, including stainless, high strength and hardened steels, aluminum, non-ferrous metals and plastics, including fiberglass-reinforced

Basic frames and components made of steel or aluminum welded construction or cast version. fully assembled mechanical structures with high precision (15 microns) for various applications

Workpiece-related fixtures with unit weights up to 6000 kg (hydraulic and / or mechanical) for multi-sided machining and multiple voltage according to our own design or customer specifications

* 4-WAY JIG
* 1-UP JIG
* SWING CLAMPS
* MANUAL CLAMPING DEVICE

Device body (tombstone / rake / tension towers)

Teaching and prototypes

Mechanical assemblies and components for machine tools and measuring machines manufacturers such carriage, brackets, recordings etc.

3-D machined parts, mold frames and accessories for the tool and mold according to drawing and record

Special parts and unique items according to sample or drawing

One of our specialties is the Hard Milling and Boring workpieces made of hardened steel or titanium

Since 1988 we have been a recognized workshop for mentally handicapped people who, due to the type and severity of their disability, cannot be employed on the general labor market, or can no longer or not yet be employed again.

In our metal processing we have the possibility to produce turned and milled parts on modern CNC lathes and the 3-axis machining center. In addition, we can offer cuts on vertical circular saws and band saws.
In addition to metal processing, we have several assembly and packaging groups at our site where parts can be assembled and packaged.

compensatory levy

According to the Social Security Code (SGB) IX § 71, every company with at least 20 employees is obliged to employ severely disabled people. The employment rate is 5%, so that for every 20 employees, one severely disabled person has to be hired. If this percentage is not reached, a monthly compensatory fee must be paid.

An order placed with the St. Josefs-Werkstätten Plaidt helps you to minimize these costs or save them entirely, since you can offset 50% of the work included in our invoice amount against the compensatory levy to be paid.

The respective amount is shown separately on the invoice and can therefore be used immediately as a certificate for the integration office.

With our extensive expertise and many years of experience, we offer you professional solutions in the areas of CNC turning, CNC milling and welding as well as tailor-made mechanical engineering and construction.
