A method of preparing organic and natural material for making teeth and typical dental devices or appliances having sufficiently hard and durable chewing surfaces, obtained from sustainable resources.

An element with an insertion groove and a dismantling groove. A method for providing a dismantling groove in an element for a product to be assembled by a plurality of elements locked by a locking arrangement including a flexible tongue. The method includes providing an insertion groove and a dismantling groove in the same element. The dismantling groove extends along the element between a first side and a second side and is configured for receiving the flexible tongue of the locking arrangement for locking the element to another element having a tongue groove. The dismantling groove is provided in the element such that it extends from the first side to the insertion groove and along a portion of the insertion groove, and is configured to receive a dismantling tool for dismantling the element from the other element.

A core support system includes a support structure. The support structure includes a frame and a support member having a saturatable engagement layer disposed over the frame. A method of machining a core material includes applying a fluid to an engagement layer of a support structure and saturating the engagement layer with the fluid, disposing a core material on the engagement layer, causing the fluid to freeze to secure to the core material to the support structure, machining the core material, melting the frozen fluid to release the core material from the support structure, and removing the core material from the engagement layer.

Lithium silicate materials are described which can be easily processed by machining to dental products without undue wear of the tools and which subsequently can be converted into lithium silicate products showing high strength.

A golf club head includes a heel portion, a toe portion, a hosel, and a striking face. The striking face includes a plurality of scorelines each having an average depth no less than about 0.10 mm, a plurality of micro-grooves each having an average depth no greater than about 0.010 mm, and a plurality of textured surface treatment regions superimposed on the micro-grooves so as to at least partially intersect the micro-grooves.

A golf club head and a method of manufacturing a golf club head are described herein. The golf club head comprises a club face with a face portion, and grooves positioned on the club face. The grooves each comprise a bottom, a first side wall adjacent the bottom, a second side wall adjacent the bottom, a first top radius adjacent the first side wall, and a second top radius adjacent the second side wall. The club face further comprises a second portion positioned between the face portion, and the first top radius and the second top radius. The second portion of the club face allows for the grooves to appear visually wider to a player, which can provide psychological effects to benefit performance, while still conforming to USGA groove widths standards.

Provided is a mobile CNC machining machine which is designed to machine a rotor of a turbomachine, wherein the turbomachine is a rotor of a steam turbine, including an x-axis, a y-axis and a z-axis which are arranged perpendicular to one another, a baseplate, a stator which is arranged on the baseplate and is movable relative to the baseplate along the x-axis, and a tool module which is held on the stator and is movable along the y-axis and along the z-axis and is designed to accommodate a machining tool wherein, guided along a circular-arc-shaped convex guide disposed on the stator, the tool module is movable about a c-axis which extends parallel to the x-axis; in that the z-axis intersects the c-axis; and in that the y-axis extends tangentially to a circular path, of which the c-axis is the center point.

The invention relates to an interchangeable milling adapter (20) for a work table (60), which comprises a receptacle (21) for a milling machine (70) and an angular adjustment (22). At the same time, an angular position (WP1, WP2) of the receptacle (21) in relation to the work table can be adjusted using the angular adjustment (22). Furthermore, a work table, a milling unit and their use for adjusting a milling machine are described.

A method for providing a dismantling groove in an element for a product to be assembled by a plurality of elements locked by a locking arrangement including a flexible tongue is disclosed. The method includes providing an insertion groove and a dismantling groove in the same element. The dismantling groove extends along the element between a first side and a second side and is configured for receiving the flexible tongue of the locking arrangement for locking the element to another element having a tongue groove. The dismantling groove is provided in the element such that it extends from the first side to the insertion groove and along a portion of the insertion groove, and is configured to receive a dismantling tool for dismantling the element from the other element. An element with an insertion groove and a dismantling groove is also disclosed.

Provided is a method of manufacturing an elbow, including: a first cutting step of cutting a material by relatively moving a cutting section of a cutting tool, which is formed of at least a part of a substantially spherical shape, along an inner side surface of the elbow to be finished in a direction from a first end surface to a second end surface of the material; and a second cutting step of cutting the material by relatively moving the cutting section along the inner side surface of the elbow to be finished in a direction from the second end surface to the first end surface of the material.
