This invention relates to a mechanism for scoring and splitting tiles usable on manual tile cutter machines of the type preferred for cutting extra-thick tiles.

The present invention discloses a pile head girdling device comprising a track arranged on a pile head and coaxial with the pile head, an electric saw installation base arranged on the track in a sliding mode, an electric saw support rotationally arranged on the electric saw installation base and an electric saw arranged on the electric saw support. The beneficial effects of the present invention are as follows: according to the solution, the electric saw cutting position on the pile head is effectively controlled on the same plane, thereby improving the quality of cutting the pile head; and the electric saw cutting position is guided and limited by means of the track, thereby improving the cutting efficiency and precision.

Provided are a method of full body cutting a brittle material without via the bend-breaking step, an apparatus of cutting a brittle material, a method of manufacturing a brittle material, and a cut brittle material. A method of cutting a brittle material, the method comprising: a conveyance cutting step of converging and irradiating an infrared ray to the brittle material linearly along a line using an infrared line heater while moving the infrared line heater relative to the brittle material in a direction along the line, thereby cutting the brittle material along the line.

Provided is a cleaving method for a glass film (G) including: cleaving, during conveyance of the glass film (G) in a predetermined direction, the glass film (G) continuously along a preset cleaving line (8) extending in a predetermined conveying direction (a) by a thermal stress generated through localized heating performed along the preset cleaving line (8) and through cooling of a locally heated region (H); dividing the glass film (G) in a width direction of the glass film (G); diverting, after the dividing, adjacent divided glass films (10), which are obtained by the dividing, so that the adjacent divided glass films (10) are separated in a front and rear direction of the adjacent divided glass films; and forming a predetermined widthwise clearance between the adjacent divided glass films after the dividing of the glass film (G) and before the diverting of the adjacent divided glass films (10).

A portable tile cutter includes a main unit having a base frame and a guard connected to the base frame, a cutter blade pivotally mounted at the guard, a driving unit connected to the guard and operable to rotate the cutter blade, a first handle connected to the driving unit, and a second handle connected to the guard and providing a grip. The component parts of the portable tile cutter are so arranged that moving one or both the driving unit and the second handle can achieve adjustment of the gap between the first handle and the grip of the second handle. Thus, the portable tile cutter can fit different users having different body sizes.

A scribing wheel for scribing a brittle material-made substrate. A disc-shaped scribing-wheel base material in use is so designed that a mid-portion of a disc periphery has the largest diameter. A diamond film is formed on the periphery by a CVD method. The periphery is ground in the middle so that a plane including a circle defined by ridge line becomes perpendicular to the central axis of the scribing wheel.

Provided are ceramic cutting methods and equipment: a beam irradiation unit for irradiating a beam of a wavelength absorbed by a pattern formed on an upper surface of a ceramic and partially absorbed by the ceramic; a coolant spraying unit for spraying a coolant onto the ceramic irradiated with the beam, wherein the pattern is removed by heating and cooling the ceramic , and is cut by reducing thermal damage by using the stress caused by the recrystallization of an upper layer or all of the ceramic or the stress generated by the thermal expansion and contraction of the upper layer or the entire ceramic, thereby recrystallizing the ceramic by heating and cooling the ceramic , or cutting the ceramic by heating until the ceramic melts, and cooling to apply thermal stress to the inside of the ceramic, followed by an additional separation process of a ceramic material without loss.

A method for processing a brittle plate includes a breaking step in which a pressing member for pressing a surface of the brittle plate and a support member for supporting a back face of the brittle plate are used to bend and deform the brittle plate and break the brittle plate along a score line formed on the surface of the brittle plate. The support member includes a flat portion that is arranged flat against one portion of the brittle plate to support the brittle plate, and a regulating portion that regulates a bending deformation shape of the brittle plate when the pressing member is pressed against a predetermined position of a remaining portion of the brittle plate. The breaking step includes breaking the brittle plate along the score line that is within the remaining portion of the brittle plate.

An automated glass scoring device and a pillar post are provided. The pillar post includes a body having a fluid inlet port, at least one internal passage, a fluid exit port, and a fluid flow metering element. At least a portion of the fluid flow metering element is disposed within the internal passage. The at least one internal passage provides a path for a fluid flow from the inlet port to the fluid exit port, and the fluid exit port is positioned such that the fluid flow exiting the fluid exit port exits in close proximity to the cutter wheel.

A field-pole magnet manufacturing apparatus manufactures magnet pieces that constitute a field-pole magnet arranged in a rotary electric machine by fracturing the magnet. This manufacturing apparatus includes: a support unit on which the magnet is placed; a fracture unit that is arranged opposite to the support unit across the magnet and is configured to fracture the magnet by pressing the magnet while in contact with the magnet; and a powder removal unit that is configured to remove crush powder produced by fracture of the magnet.
