Axial run-out accuracy at bearing diameter in mm
Radial run-out accuracy in center in mm

Parts accuracy depending on relevant control to customer-specific requirements such as higher loads machining moments or permissible mass moments of inertia can be tailored to requirements other values are available on request subject to technical changes and printing errors
The theoretical loading of our tables is significantly higher as a rule of thumb it is not only the additional load that is decisive for durability and precision but rather the largest possible bearing diameter in relation to the worktop size

Swivel tables series DAT application field automation functions enable convenient clamping of workpieces on horizontal worktop processing in vertical worktop position optimal cutting removal version customized to your requirements
