A drilling device is provided and has a driving assembly disposed on a base for rotating a plurality of drills. As such, a plurality of drills can be actuated synchronously at a time point to effectively improve the production efficiency and reduce the drilling cost.

A drive multiplying device for simultaneous drilling of multiple holes includes a housing. A drive shaft is rotationally coupled to and positioned through a first face of the housing. A first end of the drive shaft extends from the first face of the housing. A plurality of second shafts is rotationally coupled to and positioned through a second face of the housing. A first terminus of each second shaft extends from the second face of the housing. A gear set is positioned in the housing and is gearedly coupled to the drive shaft as well as each of the second shafts. The first end of the drive shaft is configured to couple to a rotary tool. The drive shaft is positioned to compel the gear set to rotate the second shafts. Drill bits coupled to the first termini of the second shafts are rotated concurrently with the drive shaft.

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.

The present application provides a chamfer removing device for wheels. The device may be used for removing a bolt hole chamfer on flange side of back cavity of a wheel in hub machining process. Drill bits are spaced a certain height from the flange side of the wheel by adjusting the relative height of an external thread guiding sleeve in an internal thread guiding sleeve, a motor and gears drive the drill bits to rotate, and a cylinder and a sliding box drive the drill bits to move up and down so as to realize chamfer removing function.

An equipment for a machining lathe with digital control comprising a movable carriage, a tool support system with integrated drive which is mounted so as to pivot on this movable carriage so as to be able to pivot about a pivot axis, as well as a device for actuating the tool support system with integrated drive with respect to the movable carriage. The tool support system with integrated drive comprises at least one mounting location to detachably receive a detachable accessory to support and drive a tool.

A two-hole core drilling machine of the invention includes a body, a vertically reciprocating carriage vertically reciprocably mounted to the body, a fixing plate coupled to one side surface of the carriage, to rotatably support a drive shaft of a motor, a pivoting plate fastened to the fixing plate under a condition that a pivot angle of the pivoting plate is changed, a moving plate fastened to the pivoting plate under a condition that a length of the moving plate from the pivoting plate is varied, a belt or chain mounted between a drive pulley coupled to the drive shaft and a driven pulley coupled to a driven shaft rotatably mounted to the moving plate, a first core bit coupled to the drive shaft, and a second core bit coupled to the driven shaft.

A system and method for installation of cabinet doors including a hardware installation kit. The hardware installation kit includes a door support, a multi-dimension spacer, a hinge spacer and a multi drill-bit jig. The door support and the multi-dimension spacer are used to support a cabinet door before being fixed to a cabinet. The hinge spacer is used to evenly place a hinge. The hinge is used to connect the cabinet door with the cabinet. The hinge is fixed through inserting fasteners thereto through the multi dill-bit jig.
