Machine Bed Delta-Tech Group, Hungary

Delta-Tech from Hungary required a stiff and vibration-damping machine bed for a special milling machine. The unique bed was made of NANODUR® UHPC, which was the best economic and technical solution. Steel rails and plates have been embedded for the subsequent precision works up to 0.01mm. The delivery period including form construction, coating and precision works was 11 weeks. More information about Delta-Tech see www.deltatech.hu.

Machine Bed Homag Group BMG 500

The milling machine for the wood processing industry is offered to the customers both with a bed made of Ultra High Performance Concrete with the special dampening recipe “SorbTech” and as welded steel construction. A You-Tube Video from Homag-Channels illustrates symbolically the damping effect of machine beds of that kind: Link to Video and link to Homag-Group Info about Homag. The beds are produced in a combi-mould with different lengths and widths.

Table for Testing Machine

Strama-MPS is a German producer for special machines and equipment. This 3.5m x 3.5m wide and about 14 tons heavy basic testing table is made of NANODUR® UHPC. It is stabil even when hot media with 140°C is permanently applied. Particual challenges was the precision machining of the stainless steel embedded parts. Link to Strama-MPS: www.strama-mps.de.

Measuring Element Polytec

Polytec Inc. is the market leader for non-contact laser based vibration and velocity measurement instrumentation. We produce several modells of UHPC-pillars up to a high of about 1m. Precision is 0.1mm directly out of the form -without further precision works. The double curved surfaces are coated. More details see www.polytec.de.

GEORG ultragind SG

GEORG from Germany manufactures high-performance machine tools. For a roll grinding machine with a precision within 5 μ for rolls weighing up to 5 tons, a rigid self stable concrete body was chosen as the machine bed. The flat guiding rails are integrated in the concrete and subsequently milled in a precision center. The machine bed has a length of 9 m and a weight of 32 tons. More information about the details at www.georg.com.

Maschine Bed Hueck Engraving

For the retrofit of a continous loop gring machine a machine bed was produced with UHPC mineralcast. The weight is over 45 tons, the length is 10 m. Durcrete was responsible for the design, the production of the rough body, the precision milling works and the special transports. More information at www.hueck-engraving.com.

Machine Bed Shandong DEED Precision Machine Tool, China

The Chinese machine tool manufacturer develops a Gantry-Machine in bridge construction with a movable crossbar. The fixed supports of the prototype with a weight more than 20 tons each were manufactured in Germany and shipped to China. Now the machine bed is produced in China, see www.deedmt.com.

Testing Table CEIT-IK4 Research Laboratory

CEIT-IK4 is a spanish reserach alliance with the University of Navarra. The institute needs a test bench with a natural frequency of 1,000 Hz. High speed tests up to 60,000 round per minutes will be performed . The test bench was manufactured with the new material E80. The stiffness is the same as a massive block of aluminium. The working table with T-nuts is made of stainless steel. Link to CEIT-IK4: www.ceit.es.
