BW-Fixators®

Series RK:

When you need to align and (re-)adjust your machine most exact, the series RK is the right choice.

BW-Fixators® of series RK are easy to operate and precise in adjustment. The time for the alignment of e.g. a lathe will be reduced significant. If the machines needs to be re-adjusted because of foundation shifting or shrinkage, it can be done simply and fast. With a wide range of accessory and anchoring methods the series RK covers nearly any application.

BW-Fixators® of series RK fulfil all requierments, conditions and properties appointed by the industry. All load-bearing and moveable parts including guiding surfaces are made from high-quality lamellar grey cast iron. To ensure the smooth handling of this parts over years, they are treated with molybdenum disulfide.

1) BW-Fixators® are adjustable up to this load.
2) This is the standard factor for the determination of the BW-Fixator® size.
3) Found by applying a changing load equal to the recommended proportional machine load. The operating
range will be covered when the machine has beenlevelled and bound down with the anchor bolts.

Formula for calculating the Resilience of BW-Fixators® Serie RK

Note: The total of the forces a – e exerted must not exceed the permissible maximum load
a) Proportional machine load
b) Tensile force exerted by anchor bolt
c) Dynamic forces
d) Changing loads (moving machine parts or workpieces)
e) Forces counteracting moments

Determination of BW-Fixator® size
The proportinal machine load recommended is a function of the net weight of the machine devided by the number of support points (BW-Fixators®). For machinery with sizable variations in partial weight, it is the heaviest machine load that has to be devided by the number of bearing points and the resulting BW-Fixator® size has to be used everywhere under the machine.
