THE DFM modular system and the small rodless DGC drive are top contenders at Festo .
As part of a full range of guided drives, they both replace elaborate user-fabricated solutions and save space as well.
The drives feature a maximum speed of 1.5m per second and end-position accuracy better than 0.5mm, offering high dynamics and precision.
As a pneumatic driving force, both the DFM-B piston rod drive with two guide rods parallel to the piston rod and the DGC, a new compact rodless drive, demonstrate a clearly distinct objective. Both can be ideally used for simple handling units.
The DFM-B is an all rounder with single axis and simple multi-axis applications in the field of handling and assembly technology.
New modular functions including shock absorbers (YSRW) and adjustable end-position cushioning (PPV) facilitate higher speeds and reduced cycle times, as well as reliable cushioning of moving loads at increased speeds.
Optional fine adjustment of the stroke is of particular interest to engineers, assuring individualised, yet simple adaptation of strokes to end-positions.
Configurations with strokes of up to 400mm and piston rod diameters of 20, 25, 32 and 40mm, as well as high torque and force resistance can be implemented in an individual fashion by the four bearings per drive unit and either plain bearing or ball bearing guides.
Various supply air and mounting options, and the SMx-8 proximity sensor which is standardised for the entire range of Festo cylinders, are important DFM features.
As a rodless standard drive, the DGC supports the continuously growing performance requirements typical of multi-axis equipment concepts.
The smallest drive of its type available on the market is furnished with a guide as standard equipment and is practically leak-free.
The stainless steel slide and the ball bearing guide provide the DGC with added precision.
A mounting concept in the form of a dovetail connector is offered for simple installation and outstanding rigidity.
In the 8 and 12mm diameter products the guided drive can be used either as a basic drive, or with recirculating ball bearing guide.
As a guided drive, the high load capacity unit is used primarily in special machinery manufacturing where emphasis is placed upon short lead times, long service life, maintenance-free operation and high load capacities.
With its minimal dimensions, outstanding performance characteristics and excellent repetition accuracy, this drive unit is extremely suitable for the electronics, light assembly, pharmaceuticals and precision engineering industries.
