Hydraulics

MAPAL offers bespoke complete machining processes for functionally relevant parts in mobile hydraulic working loops and steering circuits. In addition, the innovative and value-adding process solutions have proven popular for manufacturing components for stationary hydraulics.

(1) Hydraulic valve housing: Machining solutions for hydraulic valve housing

Everything depends on the main bore. Manufacturing valve housings
is the supreme discipline in the world of fluid power. For years, MAPAL’s
expertise has been in demand for the spool bore. The gap dimension
with the spool depends on the accuracy of this bore, so that the
hydraulic oil can only flow in the required direction without
leaking. This is very narrowly defined in modern hydraulic
valves. The roundness, cylindrical form, straightness
and surface finish of this bore are therefore crucial.

Basic procedure – analysis of the machining process

As technology partner, MAPAL supports customers with regard to complete process design. The experts pay particular attention to the cost drivers here, which can often be found in the function-relevant bores. Based on the respective honing procedure, the part requirements and lot sizes, MAPAL designs the perfect machining strategy in dialogue with the customers.
One objective unites all activities: designing the most economic process, starting with piloting, boring and semi-finish machining up to the efficient honing process.
(2) Control block: Control block

The hydraulic control block connects diverse valves and control components. These are installed in or mounted on the control block, which acts as a control and distributing system in hydraulic circuits.

(3) Axial piston pump: Axial piston pump

Axial piston pumps and motors together are referred to as axial piston machines. An axial piston pump transforms mechanical energy into hydraulic energy and an axial piston motor transforms hydraulic energy into mechanical energy.
Axial piston machines are characterised by a high degree of stability and good interior sealing, which allows high pressures.

(4) Orbitrol: Lenkorbitrol

Das Lenkorbitrol ist das zentrale Steuerelement hydrostatischer Lenkungen. Der von einer Hydraulikpumpe geförderte Volumenstrom wird entsprechend der Bewegung am Lenkrad in die Arbeitsräume eines Hydraulikzylinders geleitet, der die Achsschenkellenkung betätigt. Für die dauerhafte Funktion der Lenkungen wird ein Prioritätsventil eingesetzt.

Grundlegende Vorgehensweise – Analyse des Bearbeitungsprozesses

Als Technologiepartner unterstützt MAPAL den Kunden bei der kompletten Prozessgestaltung. Dabei achten die Experten besonders auf die Kostentreiber, die oftmals in den funktionsrelevanten Bohrungen vorzufinden sind. Ausgehend vom jeweiligen Honverfahren, den Bauteilanforderungen und Losgrößen, gestaltet MAPAL im Dialog mit den Kunden, die perfekte Bearbeitungsstrategie.

Ein Ziel vereint alle Aktivitäten: den wirtschaftlichsten Prozess, beginnend beim Pilotieren über das Aufbohren und die Semi-Finish-Bearbeitung bis hin zum effizienten Honprozess auszulegen.
