Know-how advantage and quality standards
We have more than 50 years of experience in technically demanding design and manufacturing of cylinders. The heart of our production are state-of-the-art CNC processing machines and CNC lathes. On top, we work with three complete processing machines up to a component length of 3000 mm, equipped with universal milling spindle, chuck and counter-chuck for automatic workpiece transfer, steady rests as well as automated tool change from a storage with 100 tools. Our own grinding, honing and polishing machines complete the high level of vertical integration and guarantee the highest quality standards in production.
ISO certified cylinder production
ISO-certified cylinder manufacture
Our comprehensive machine tool complex in a manufacturing area of 2500 m2 is specially suited to the manufacturing of standard, industry-related and customer cylinders for industrial applications up to 10000 mm stroke and 1500 mm piston diameter. This allows us to guarantee rapid order processing even for large projects.
Depending on the number and size, piston rods are machined on cycle-controlled lathes or CNC lathes and ground if necessary. Even long and large cylinder tubes are turned in the house completely outside and inside - with boring bar and anti-vibration holder - and honed to the finest surface roughness.
Cut-to-lengh parts or stroke-independent parts, such as heads, plates, ball joints, guide bushes and pistons, are manufactured on state-of-the-art turn-mill centers with complete machining. Boring mills and CNC machining centers in combination with classic CNC lathes prove themselves for large crosspieces. The quality assurance of the production parts is handled directly by the machine operator. For serial parts, the actual dimensions for serial number tracking are logged. Plasma cutting, automated sawing and welding systems round off the machine spectrum on the blank side. All parts are deburred, meticulously cleaned and preserved.
Cleanliness is paramount in the assembly. Depending on the size, we assemble our cylinders separated from the production in our own assembly hall on work benches or hydraulic vices in horizontal or vertical position. The intermediate parts from the production, purchased parts, seals and guide belts are stored according to the FIFO principle in an automated warehouse lift, from where the picking of the parts for assembly takes place.
Basic and topcoat paints according to customer requirements are handled in the in-house paint booth. Cylinders with a length of up to 12 m are no problem for our double cabin with upstream washing and degreasing cabin. An own drying cabin ensures the efficient and high-quality processing of high layer thicknesses.
All hydraulic cylinders are statically tested for maximum pressure, tightness, pressure retention and ease of movement according to specified test plans. The results are documented in the test report. Automated inspection of repeat parts and batch-related item logging are proven features of our self-developed test bench. Permanent monitoring of product and process quality according to ISO 9001 is a matter of course.
