Serres Gear Factory has been a family business for over 50 years, always combining tradition and modernity in its services and products.

Therefore, the Serres gear factory is always very close to its customers and suppliers, as well as the delivery of high quality products.

As a medium-sized company - founded in 1996 - we have the most modern manufacturing techniques and practices in the production of dental and sprockets and employ qualified staff with many years of experience.

In addition to the standard chain and sprocket we manufacture custom-based sketches, drawings and patterns of our customers.

Our ambition is to be a reliable partner for our customers. We are sure to meet the demands placed on us in terms of quality and service.

The Zaron precision parts Eberswalde GmbH is a company of the metalworking industry, was established in 2002 (slewing bearings through spin-off from the DRE / CON GmbH). By means of a new manufacturing process precision workpieces are individually manufactured according to the specifications and designs of our customers. This newly developed broaching method is patented and protected internationally.

Our customers
Our customers are mainly in the areas of safety equipment, instrumentation, tools, and electrical engineering. Furthermore, we manufacture for companies in the automotive industry and its suppliers.

Toolmaking
Our in-house tool is used not only for its own broaching tools and devices, but also stands our customers with appropriate capacity.

Employee
Zaron employs a highly motivated and qualified staff, who has many years of experience in sophisticated metalworking.

Our innovative broaching method differs in many respects from the conventional spaces.The main difference is in the design of the tool. This consists of lined cutting plates, using shims gaps are created, each forming the chip chamber. All clamping stages are mounted in this way and connected by guide elements and fasteners to a stable Räumpaket. This simple geometrical construction of the cutting plates enables easy resharpening without special equipment.

Precision in tooling
The nuts and bolts when Zaron methods are the tools. The end product can only be a precision part, if there are already the tools. Is achieved the precision wire EDM machines. Corresponding to the finished contour of the finished part, the exact geometries of the individual cutting boards are fixed in the design and pass it directly to the machine for processing.

With our procedure can be produced virtually every conceivable profile contours, regardless of whether any serrations or symmetric or asymmetric contours.The design and manufacture of the tools is carried out by highly qualified personnel on CNC EDM machines in-house.

Our core business is the profiling of external contours in with the new broaching, including toolmaking. This process is in many cases an economical alternative to milling, planing and slotting of teeth and grooves or other profiles.

Products:
Synchronizer body: Clean the teeth and grooves in one setting. Outer diameter to 90 mm.
Contours: Symmetrical or asymmetrical.
Teeth
Gears and toothed segments.

Our services are in addition to the outdoor and indoor spaces:
- Wire EDM
- Surface grinding
- Turning
- Milling
- ECM deburring

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.

For over 25 years we have been active in the field of drive technology. In this time we have a lot of projects handled and expanded our expertise. Initially we were working as supplier of gearing elements for the engineering industry - we supplied standard parts from our catalog as well as custom-made according to the requirements of our customers. Today we have our priorities set increasingly in the field of electro-mechanical solutions for the realization of linear movements. With our ZIMM screw jacks modular system, we offer an extensive range of products to meet the needs and desires of our customers. The applications are so versatile that we only can give some classics, like eg theater and stage equipment, height adjustment of tables, platforms, conveyor belts, rollers and roller adjustment or precise positioning of loads in assembly and handling technology. The modular system offers you the opportunity to select from many standardized components - with the advantage of a short delivery time. In addition, we offer many additional components and possible solutions to you -

Our drive elements made of plastics are manufactured exclusively by injection, optionally at special rework in machining processes.

With our advanced injection molding machines and by ongoing investment in current technology, we are able, our products cost-effective and automated at the highest level to manufacture.

The injection molding process allows us to produce both parts with high accuracy as well as mass-produced in a short time.

The necessary tools for this are either already available or are prepared by Zipperle itself.

In addition, we also manufacture special parts in various geometries and in a variety of chemical-resistant plastics.

AKROTEC - a new material made of aliphatic polyketone (PK)
This material has high mechanical properties,
has very good chemical resistance and toughness
Shock loads, as well as a very high abrasion resistance.

We present in great detail the technological opportunities of one of the factories of ZMM Bulgaria Holding JSC, ZMM Nova Zagora which is specialized for the production of gear wheels – spur and helical gears.Factory is equipped with gear grinding machines type Reishauer and Okamoto and also well equipped control laboratory.
In February ZMM Nova Zagora, put into operation a new gear-grinding machine Niles ZE400/500 of the German company KAPP-NILES. The machine was purchased with the support of the Ministry of Economics and the Operational Program "Development of the Competitiveness of the Bulgarian Economy 2007-2013". It achieves quality 4 according to DIN 3962 for profile grinding of cylindrical gears with a maximum diameter of 500 mm. The machine is supplied with CAM software for creating a programs.
ZMM Nova Zagora produce mechanical multiple friction disks clutches, spare parts, sprockets, toothed belt pulleys, accessories and units (gear boxes) for metalcutting machines, agricultural machines, woodworking machines and other machine tools.
There is also workshop for thermal treatment as cementation and induction hardening. ZMM Nova Zagora is certified according ISO 9001:2000 and executes orders from European companies.
