The invention relates to a method for monitoring a machining tool that is used for machining primarily metal materials, comprising a cutting tool, wherein the cutting force, feed force, and passive force can be adjusted during machining, and comprising sensors to measure forces. In order that machining can be stopped 2 to 60 seconds, preferably 2 to 10 seconds, prior to failure of the cutting body, the invention proposes that the sensors continuously sense at least one of said forces during machining and machining is stopped if a sudden reduction in the sensed force occurs.

The cerAMfacturing project will develop a completely new approach for ceramic multi material additive manufacturing which will allow series production of customised and multifunctional components for manifold applications for obtaining property combinations, like electrical conductive/electrical insulating, dense/porous or two-colored components. In five case studies demonstrators for personalized medical products micro surgical tools, implants, and remedies such as consumer products will be manufactured starting with the patient specific physical dimensions and ending with components validated under practically relevant conditions. For achieving these goals manifold tasks will be solved starting with method and device development. Especially suspension based additive manufacturing methods will be developed and qualified in cerAMfacturing, because this route promises a much better component performance in comparison to powder based methods. Multi material applications play a dominant role in the project. Beside ceramic/ceramic also ceramic/metal material combinations will be developed. For that purpose either additive manufacturing methods will be qualified or AM methods will be combined with conventional shaping routes like tape casting or ceramic injection moulding. The last mentioned combination of technologies will allow the individualisation of large series production components. Appropriate control methodologies to guarantee a high quality level of the custom made products will be implemented. The cerAMfacturing project will provide the technical equipment for combining AM steps with conventional ceramic shaping routes.

An instrument set for removing a ceramic cup insert (I) from a metal shell (2) of a hip-joint implant has a holding element (3), a securing device (4) connectable to the holding element (3), at least one spacer (5) and a head (6). Holding element (3) has at one end an adapter device (7) for securing the head (6). Head (6) has an adapter location (8) for securing adapter device (7). Holding element (3) has at another end a coupling device (9) for a tool for rotating holding element (3) about its longitudinal axis (10). Holding element (3) has an adjusting thread (11) on its circumferential surface. Securing device (4) has an inner thread and can be turned on the adjusting thread (11) in the longitudinal axis (10) of the holding element (3). Spacer (5) is arranged on the securing device (4).


A ceramic bone replacement material and to a generative method for producing said bone replacement material, in particular ceramic bone replacement materials used in implants and preferably in spinal column implants. Generative manufacturing methods make it possible to shape the structures of the bone replacement.

CeramTec GmbH | Date: 2014-04-07

A ceramic component to be securely connected to an additional component in force-locked manner. A joint prosthesis comprising a ceramic sphere (1), a metallic sleeve (2) and a base plate (3) with a cylindrical projection. The connection between the ceramic sphere and the base plate or shaft (7) is secured by a screw (6).


A package for receiving an adapter sleeve for a hip endoprosthesis, the hip endoprosthesis comprising a ball head which has to be pushed onto the adapter sleeve with a defined pushing-on force. For simplification and secure fastening of the ball head on the adapter sleeve, it is proposed according to the invention that a device for the mounting of the ball head on the adapter sleeve is integrated in the package and this device comprises indicating elements which indicate that the defined pushing-on force has been reached when the ball head is pressed onto the adapter sleeve. Preferably the package has indicating elements.

The invention relates to a hip joint prosthesis comprising a ceramic inner sliding cup that, on its outside, is surrounded by a plastic covering, for inserting into an outer metal cup or for directly implanting with the aid of bone cement. A ball head, which is mounted on a shaft, articulates inside the inner sliding cup, and said shaft can be anchored inside the femur. In order to increase the strength with regard to tilting and turning, the exterior of the sliding cut is provided with a structuring.
