CNC-MILLING PARTS - The CNC milling is divided into two fields. Milling automotive parts in bigger volumes often made from castings or forgings. The second focus is on complex milled parts for mechanical engineering, for hydraulic components and for aviation and airspace in medium and small series. The ORCA-group has a modern park of machinery. This includes CNC milling centers with up to 260 tool holders and 5 axis simultanious machining and also universial CNC turning/milling centers. To fulfill the necessary demands in processing and programming the production is supported by modern CAD/CAM systems. 3D CNC measuring machines and a variety of modern testing equipment are used to ensure the highest quality standards.

GEARING TECHNOLOGY - The competence of the ORCA-group in the gearing technology is focused to the production of different types of gears, pinions and worms from module 0,2 up to module 4,0. Modern hobbing machines as well as turning machines with special equipment are used in production. The measuring is supported by several two flanks master gear devices, Klingelnberg P26 and Gleason MP150.

GRINDING/ FINISHING - The ORCA-group localized the whole grinding technology at the Zisterer GmbH plant. The high performance needed for hydraulic components guarantees a high quality standard and result in a top class machinery and measure equipment as laser measuring devices, profile testing equipment and roughness measuring units.

|Ultrafine grinding e.g. Strausak T70||bearing shaft Ø 0,5 mm - Ø 6,0 mm|
|Shaft and ball-finishing e.g. Supfina - Thielenhaus||Ø 6 mm - Ø 50 mm, length 250 mm|
HONING - this special process allows to finish very accuarate diameters with a defined surface-roughness also in heat treated parts as gears, sleeves, valves and hydraulic components. The majority of the honing machines are equipped with a automatic robot loading system. For tolerances under 0.01 mm, measuring systems are used in the process.
PROFILE-ROLLING-TECHNOLOGY - Next to the classic machining processes, the ORCA-group also uses the forming technology by profile rolling machines. The profile rolling is used for rolling threads, worms in full material and optimazing of pre-milled tooth flanks. This technology has been successful approved especially during the manufacturing of drive worms.
For this technology, the ORCA-group uses profile and thread rolling machines PR 15 HP from "Profiroll".
HEAT TREATMENT/ COATING - a lot of our products are highly stressed and used in applications allowing no wear. Therefor heat treatment and coating is a common process. The ORCA-group has long experience with these complex technologies and together with our reliable suppliers we support our customers for their requirements. The treatment used for automotive, hydraulic or aviation products often are very different. This is the big challenge of the ORCA-group generating synegies between our competence centers. Additionally the ORCA-group uses different surface treatments in-house as barrel finishing, polishing, sandblasting and tempering after heat treatment. Our company location in Pila / Polen has its own maschinery of hardening furnaces for case hardening, annealing, tempering and aging.
ADDITIONAL INFORMATION - The ORCA-group evaluates their suppliers looking at their quality systems and the performance of their deliveries.
ASSEMBLIES - many customers appreciate the manifold opportunities of assembling work realized by the ORCA-group. In coordination with our customers the necessary testing and gaging devices will be specified and constructed.
MASCHINERY/ ENGINEERING - the ORCA-group is able to build its own assembly lines. Therefore the in-house engineering and the well equiped tool shop are mandatory. This of course is also very helpful for any trouble shooting.
production / machinery
The production focuses of the ORCA - group are aligned to the respective requirements in the areas of expertise. The aim is to produce effective and economically optimized conditions in each production area.
For this a total of approximately 15.000 square meters of production space is given to fulfill future requirements such as economy, enviromental protection, sustainability etc. All production areas are logistically and ecologically optimized for examples the plants are equipped with modern ventilation systems, chip deposal facilities and crane installation.
In our production areas adequate production equipments, machine equipments and measuring instruments are availabel for the respective tasks to ensure the necessary flexibility and reliability in our productions, machine groups are preferably the same type and bundled in respective manufacturing sectors.
