Distance adjustment

distance compensation

Distance adjustment in machine and system construction is the bridging of gaps between individual components or between the floor and the machine foot. Intermediate layers and underlays made of metal sheet and plastic can be used to optimally orient machines and components. The slotted and precision shims are placed for precise fit between components or between the machine foot and the surface on which it rests. This offers the advantage of allowing the adjustment procedure to be carried out very flexibly without removing individual machine components and grinding or otherwise machining them.

Vertical distance adjustment at the machine foot

Vertical distances between the machine foot and floor are generally bridged with standard slotted shims (precision plates). Slotted shims are available as solid sheets or edge-bonded parts under the brand names peel-plate, single-plate, and vario-plate. The thicknesses of the individual plates range from 0.05 mm to 20 mm. The solid precision shims can be used individually or, for finer intervals, in combination. Edge-bonded sheet packages offer the advantage of being usable in their entire thickness or, if the thickness is too great, allowing simple reduction by removing individual sheets.

Horizontal distance adjustment between components

For the bridging of horizontal gaps, individual precision shims that are perfectly adapted to the individual components are used. These bridging plates are made either of solid sheet or of peelable laminated shim stock or laminated plastic. The minimum thickness of the individual sheets is 0.05 mm. Laminated shim stock is available at foil thicknesses of as low as 0.025 mm. The standard materials for precision shims are stainless steel, steel, aluminium, and brass. Peelable parts can also be manufactured as light, easily peelable layers of plastic.
