Parts accuracy depending on relevant control. 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.
