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) 油圧バルブハウジング: 油圧バルブハウジングの加工ソリューション

すべてはメイン穴の加工品質に依存します。流体技術部品の加工において、バルブケースの製造は、最も高い精度が要求される分野です。ここでは長年にわたってマパールのスプール穴加工に関する技術ノウハウが必要とされてきました。スプールとスプール穴のギャップは、加工穴の精度に左右され、作動油は一定の方向にしか流れないようになっています。
最近の油圧バルブ穴は、加工公差の幅が非常に狭くなっています。そのため、加工穴の真円度、真直度、円筒度、仕上げ面精度はきわめて重要になっています。

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.
(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: Orbitrol

The orbitrol is the main control element of hydrostatic steering systems. Depending on the movements of the steering wheel, the volume flow produced by a hydraulic pump is directed to the working area of the hydraulic cylinder, which operates the Ackermann steering. A priority valve is used here to ensure steering system durability.
