Disclosed herein is a scribing wheel having a predetermined thickness and a disk shape. The scribing wheel includes: a wheel body configured in such a way that at least a peripheral edge portion thereof is gradually reduced in thickness from the center to the radial outside; and a cutter part including recesses and cutting blade teeth which are alternately arranged along the peripheral edge portion. Each recess is formed by a combination of side recess portions formed in opposite side surfaces of the peripheral edge portion of the wheel body and an edge recess portion formed in the peripheral edge of the wheel body.

A cutter edge is caused to slide to generate a plastic deformation on a first surface of a brittle substrate, thus forming a trench line. The trench line is formed so as to obtain a crack-free state in which the brittle substrate seamlessly continues in a direction intersecting the trench line directly below the trench line. The crack-free state is then maintained. A crack of the brittle substrate in its thickness direction is extended along the trench line to form a crack line. The brittle substrate is divided along the crack line.

The invention relates to a cutting head (2) that includes sets of bearings comprising fixed bearings (31, 32) and an adjustable bearing (33) that act on races (11, 12) of a monoguide profile disposed on different planes. Each adjustable bearing (33) is mounted on a rocker (4) having a first end (41) rotatably mounted on a shaft (5) fixed to the cutting head (2), and a second end (42) that presses against an elastic element (6) situated between the second end (42) of the rocker (4) and the case of the cutting head (2), the elastic element (6) determining the pressure of the bearings (31, 32, 33) against the races (11, 12) of the monoguide profile (1).

A cutter head includes: a support platform; a double curved surface member mounted on the support platform and having a first curved surface and a second curved surface; a cutter wheel support member and a roller wheel support member moveably mounted on the support platform, respectively; a cutter wheel and a roller wheel mounted on the cutter wheel support member and the roller wheel support member, respectively; a first transmission mechanism mounted on the support platform, configured to be mated with the first curved surface, and connected to the cutter wheel support member, so as to transmit a movement of the double curved surface member to the cutter wheel; and a second transmission mechanism mounted on the support platform, configured to be mated with the second curved surface, and connected to the roller wheel support member, so as to transmit a movement of the double curved surface member to the roller wheel. The cutter head has a compact structure, and it improves the levelness of the cutter wheel and the roller wheel, and increases the mechanical precision.

A glass plate processing system includes a first aligning means. When first and second glass plates different upper and lower surface areas are processed, the first aligning means aligns a first side edge extending in a front-rear direction on one side in a width direction of a first glass plate to be processed first with a first side edge extending in the front-rear direction on the one side in the width direction of a second glass plate to be processed later. The glass plate processing system causes the first aligning means to align the first side edge of the second glass plate at a position of the first side edge of the first glass plate to perform processing on the second glass plate. The glass plate processing system shortens a moving distance and arrival time for a processing device and shortens cycle time of processing.

A method of fabricating a glass panel includes forming a non-chamfered glass panel by cutting a glass sheet. The non-chamfered glass panel is formed by cutting the glass sheet along a first sideline segment, cutting the glass sheet along a corner line segment set connected to the first sideline segment, and cutting the glass sheet along a second sideline segment connected to the corner line segment set. An extension of the first sideline segment and an extension of the second sideline segment intersect each other at a first interior angle narrower than 230?. The first sideline segment and the corner line segment set are connected at an interior angle wider than the first interior angle and 180? but narrower than 230?. The corner line segment set and the second sideline segment are connected at an interior angle wider than the first interior angle and 180? but narrower than 230?.

A glass-plate working apparatus 1 includes a cutting section 2 serving as a processing position for forming cut lines on a glass plate 5, a grinding section 3 serving as a processing position for grinding peripheral edges of the glass plate 5, a bend-breaking section 4 serving as a processing position between the cutting section 2 and the grinding section 3, and a glass-plate transporting section 6 for transporting the glass plates 5, and further includes a feed conveyor 7 disposed on the side of carrying in to the cutting section 2 and serving as a glass-plate carrying-in section, as well as a discharge conveyor 8 disposed on the side of carrying out from the grinding section 3 and serving as a glass-plate carrying-out section.

A cutting and separation head for manual ceramic cutters, including a body that carries a grip handle and a cutting tool, mounted on movable supports on longitudinal guides of the cutter, and able to rotate with respect to a first transverse rotary shaft; a separator provided with a foot, a class 1 lever, and a first coupling element in the separator that is couplable to a second coupling element in the body of the head; and a cam for releasing the first and second coupling elements, the cam being mounted on the body and relatively rotatable between a first position and a second position.

Embodiments herein relate to a workstation that includes a cutting tray and one or more rails. The workstation may include a perimeter cutting element configured to travel along the rails, and the perimeter cutting element may include a perimeter blade mounted at least partially within a perimeter cartridge. The workstation may further include a profile cutting element configured to travel along the rails, wherein the profile cutting element includes a profile blade mounted at least partially within a profile cartridge. Other embodiments may be described and/or claimed.

Cutting apparatuses and methods of use thereof are discussed. For example, the cutting apparatus may include a chassis with one or more substrate interfaces and a scribe guide. The cutting apparatuses also may include a plurality of support pistons, a deformable support, a locking mechanism, and/or an anchor extension. The support pistons may be adjustable to generally conform to a substrate, such as a non-planar substrate.
