Provided is a hole drilling machine and the method for drilling an oval hole and an inner-diameter-changing hole by means of the hole drilling machine, the machine and the method being configured so that the oval hole can be shaped with high accuracy and drilling of a complicated hole such as the inner-diameter-changing hole can be performed with high accuracy. A hole drilling machine 100 includes a spindle 101 and an auxiliary spindle 120 holding both end portions of a processing tool 102 having a cutting blade 103. The spindle 101 includes a spindle drive motor 106 configured to rotatably displace the processing tool 102 on a circular path, and a tool turnable-drive motor 105 configured to spin the processing tool 102. The auxiliary spindle 120 includes an auxiliary spindle drive motor 120b. In the auxiliary spindle drive motor 120b, a tool fitting portion 120a in which a tip end portion of the processing tool 102 is slidably fitted is synchronously rotatably driven on the same circular path as that for the spindle 101. A table reciprocatably-displacing mechanism 111 is provided between the spindle 101 and the auxiliary spindle 120. The table reciprocatably-displacing mechanism 111 reciprocatably displaces a work piece WK in an X-axis direction perpendicular to an axial direction of the spindle 101.

A robotic forming system and method for forming a tapered hole in a workpiece include a housing and a nose extending from the housing. The housing defines an internal chamber. A vacuum gate is in fluid communication with an internal cavity of the nose. A seal is within the nose. A first spindle includes a first operative head. The first spindle is retained within the internal chamber. The first spindle is configured to be moved between a first stowed position within the housing and a first operating position in which the first operative head extends into the nose. The first operative head is configured to form an initial hole within the workpiece. A second spindle includes a second operative head. The second spindle is retained within the internal chamber. The second spindle is configured to be moved between a second stowed position within the housing and a second operating position in which the second operative head extends into the nose. The second operative head is configured to modify the initial hole to form a tapered hole.

A key cutting machine is provided. The key cutting machine comprises a rotary cutter, an anvil and control circuitry. The rotary cutter is for cutting into the blade of a key blank. The anvil is for stabilising the key blank whilst the rotary cutter is cutting the key blank. The control circuitry is configured to: cause at least one of the anvil or the rotary cutter to move, such that the anvil is located substantially at a first face of the blade of the key blank and the rotary cutter is located substantially at a second face of the blade of the key blank, the second face of the blade of the key blank being on an opposite side of the blank to the first face; and cause the rotary cutter to cut into the second face of the blade of the key blank.

Provided is a hole cutting apparatus for forming a hole in a glass laminate substrate including a substrate, an adhesive layer, and the glass layer which are sequentially stacked. The apparatus includes a rotatable body, and a cutter coupled to a lower portion of the body, configured to form a hole in the glass layer by cutting the glass layer and at least a part of the adhesive layer and to deburr a surface of the hole, and including a cutting portion having a cross-sectional area in a horizontal direction that gradually decreases in a downward direction.
