MANUFACTURING PROCESS OF THE PISTON-CYLINDER ASSEMBLY

PISTON

The piston body is the most fundamental part of the piston-cylinder assembly. It is the base on which the rest of the components are assembled. During the operation of the lift, the need for a flawless "cooperation" between the cylinder and the piston body requires high accuracy of its mechanical operation. This results to the avoiding of leakage and other problems.

The first stage of the engineering of the body is the cutting of the tube at the required length according to each order. The stage of its alignment follows up, being performed into special hydraulic presses, and the welding of the micro-components at its two edges, with an automatically programmed welding machine.

The micro-components of the piston (plug, bottom, bottom ring, etc) are manufactured by massif steel in programmed CNC lathes and state-of-the-art engineering centers, in order to achieve high productivity, perfection in terms of component clearance and their exchangeability.

At the next stage, the most important stage of the manufacturing process, the piston is forwarded to the place of the final grinding of its external surface.

Aiming at the improvement of its flexibility of the manufacturing process and the increase of its production volume, the company has obtained state-of-the--art finishing grinding machines. The installation of the machines mentioned before, given that it is fully programmed and incorporates automatic feeding, directly resulted in the innovation, increase and improvement of the offered products.

The final engineering is performed by a Honing programmed machine, that makes possible the achievement of a perfect roughness of surface (2-3 m), as well as eliminating completely the oval shape.

CYLINDER

The cylinder is the external part of the piston - cylinder assembly and creates the envelopment into which the piston moves. The stages of its manufacturing process are similar to the piston stages, excluding the stage of final grinding of the external surface. The head, that carries the tightness and drive components, is adjusted to the upper extremity and is manufactured on CNC lathes.

The final stage, before the storage, is the assembling of the piston - cylinder assembly. According to the European lift regulations (ΕΝ 81.2) and the quality control procedures that are defined by the ISO 9001 Quality Assurance System its testing in high pressure (80 - 100 bar) is required. When the testing is finished, the piston - cylinder assemblies are dyed externally and forwarded to the prefabricated products store.
