Production service aspiring to perfection

We are happy to take on highly complex production assignments for our customers and to elaborate quality solutions which aspire to achieve perfection. Every division of ZELTWANGER Maschinenbau GmbH takes this ambitious aspiration as the quality standard for its day-to-day work.

But the most important factor in our company is its workforce: a rock-solid, totally reliable team of men and women whose commitment and enthusiasm for their work and the manufacture of top quality products spurs them on to achieve ambitious standards and ever higher performance with each passing day.

It is this motivation which has created scope for our extreme work time flexibility. We produce in two to three shifts six days a week.

Our entire technical innovative drive and resolute quality orientation are channelled into the production of challenging prototypes, complete assemblies, small-scale series and individual components.

Production processes

High-tech is the standard at ZELTWANGER Maschinenbau GmbH. This is reflected in our highly qualified team of specialists, in our logistical division of labour, and in our use of the very latest production processes and technologies.
Our machining centres and lines are programmed and controlled over a central network. Innovative 3D programming systems permit even the most complex workpiece contours to be machined.

In the metal cutting field, our CNC milling centres use 5-sided machining techniques. All our lathes are fitted with power tools and with a C and Y axis. Our products are characterized by optimum grinding results with millimetre range precision for the ultimate in productivity.

With our high-precision spark erosion cutting machines we also have the capability to manufacture custom-produced parts and small-scale series in-house.

Materials - broad selection, quick availability

Alongside our extensive ultra-modern machine outfit, we also benefit from a wide range of stocked materials in our automatic high-bay warehouse. These include all steel, titanium, stainless steel and high-strength alloys as well as all popularly requested aluminium alloys.

We also offer a raw material procurement and storage service to customer order.

Welcome to Zerspanungstechnik Beyer, your reliable contract manufacturer for machining solutions from overseas on beautiful Chiemsee. Since 2007, we have been specialists in manufacturing parts, whether prototypes, individual parts, small, medium or large series, we offer you the ideal solution for your project. With our CNC machining centers, we are able to make from all machinable materials (e.g. steel, stainless steel, aluminum, plastic, etc.) to implement your projects with maximum precision and reliability. Customer satisfaction is our top priority, which is why we also offer an associated measurement report for our workpieces, if required.
Don't hesitate to contact us, we will take care of your request.

We have been manufacturing for a wide range of customers and industries since 1992 - from the electronics, glass or automotive industries to mechanical engineering. State-of-the-art machines enable us to produce at the highest level of precision.

In the newly built production hall in 2000 we mill parts up to 3000x800x720mm, we turn with a bar diameter of 80mm, chuck parts up to 300mm in diameter and we grind with max. 800x500mm.
Series production is permanently checked in the measuring machine, measuring range 406x365x305mm. As a medium-sized company based in the Bavarian Forest, we and our employees are particularly challenged to assert ourselves on the market. For our production, this means being more perfect, cheaper and more reliable than the competition.
As a specialist in machining, ZTS manufactures turned and milled parts from non-ferrous metals, quality and stainless steels, plastics or high-alloy special steels.

Our production is geared towards small and medium series - therefore flexible and open to all customer requests.

Fast delivery on time, precisely machined parts, the highest quality and efficiency in production - these are the prerequisites for perfect cooperation.

Our special are spiral bevel gears untill 600mm diameter and grinded teeth from quality 5 or bader and spur or helical gears until 1.000mm diameter with grinded teeth from quality 6 or bader.

ZSO sees itself as a competent supplier and service provider in the metal Zerpanung (turning, milling, grinding) and component assembly.

In the area of contract manufacturing (turning, milling, grinding and surface treatment), we offer our services from small series to medium runs with great variety. Here, the annual volumes of 5,000 St. can (with high complexity, Dreh-/Frästeil 50 min processing time) vary up to 1.4 million St. (simple turned part, about 1.5 min. Processing time). The possible workpiece sizes reach the maximum diameter of 400 mm when turning. In radial grooves on the outer contour may occur reduction of the workpiece diameter.

During milling, we can work with our machining centers cube sizes up to 1000 mm.

We also perform desired by impermeability tests also.

The company ZSO GmbH is a company of senata GmbH (www.senata.de), an owner-managed medium-sized companies with a high share of equity.

The main sphere of business is a production of the assembled configurations with various numbers of parts accordingly to the technical documentation delivered by customers. The company owns the proper technology placed on the production area of 3600 m². The technology provides the possibility to machine the large sized objects as well. (Max. sizes: 5000 x 2500 x 2200 mm, the mass up to 10 tons). The achievable precision is IT7. The welding workshop is equipped with modern welding technology.

ZZ-products can be found both at home and abroad in all areas of machine and plant facilities.
