GIROUD

Mécanique de Précision SA
Dovetail or roller bearing slides, sledges, pneumatic insertion press, etc.

Machines, precision instruments, and other equipment with movable parts that have to travel in a precise straight or circular line with a minimum of backlash and friction. These prefabricated components are supplied ready for use and relieve designers of the need to keep “reinventing the wheel”.


GIROUD Mécanique de Précision SA
Established in 1968, Giroud Mécanique de Précision SA in Le Locle, Switzerland, designs, develops, and makes high-precision mechanical components, sliding stages that run on dovetails or on linear antifriction bearings, and various other products.


Separate elements…
Standard dovetail-type sliding-stage modules have a fixed baseplate on which a moving sledge travels, controlled by a micrometer gauge and vernier scale that measure in 10µm units. Lateral backlash is controlled by a gib strip that transmits the pressure of setscrews to the guide. The two main components, whose surfaces are all precision-ground, are made of GG25 cast iron.
The modules are available in seven sizes: 30, 50, 75, 100, 125, 150, and 200; each number refers to the stage width in millimetres. Depending on type, travel of the standard version varies from 10mm to 400mm. Despite being extremely compact in height, these elements are stiff and very precise.

… or combined systems
Two sliding tables above each other form a complete XY cross-slide that can be fitted either to a fixed base, or to a rotary baseplate with a protractor scale in 1° divisions along its circumference. Extra-thin cross-slides are also available, with heights from 26mm to 36mm, according to type.

Options
The basic equipment is supplied without holes for fixings. However, a special feature of Giroud production is its ability to supply any of its stages finished to customers’ special requirements.
Optionally, slide rails can be supplied with short verniers, handwheels, angular gears, blocking systems, central lubrication, and/or with bellows to protect the slide rail, but in that case the size of the bellows reduces the useful length of travel.

Another possibility, for example, is to combine the slide rails to form an XYZ triaxial system. Other types can be made to customers’ specifications, such as slide rails with built-in counters, sledges coupled to move in opposite directions, etc.

These slide tables are specially designed for applications that require incremental movement in the µm range, notably for straight-line travel under digital control, by prestressed linear antifriction bearings instead of conventional slide surfaces.
The drive is controlled by a high-precision micrometer gauge of 1mm thread pitch with a doubly prestressed nut that controls axial backlash. It eliminates backlash in the µm range in any geometrical direction and is thus is suitable for high-precision applications. In their basic configuration, these elements are supplied with protective bellows for the slide rails at the start and end of travel. These slide rails are 102mm wide and have an overall height of only 32mm; they are available for 25mm to 200mm travel.

Pneumatic insertion press
Giroud pneumatic insertion press are specially designed for the watchmaking industry. To ensure a gentle and deformation-free insertion of even the most fragile components, you can associate the press with a special designed control unit. Two types are available, each of which can be supplied with three different baseplates.


General note: All Giroud products can be adapted to specific requirements or made to order.
