A working head for a machine tool with non-orthogonal axes, with a support movable along three Cartesian axes, includes a first body mounted to the support to rotate about a first polar axis parallel to one of the Cartesian axes, a second body mounted to the first body to rotate about a second polar axis tilted at a predetermined first angle from the first polar axis, a tool holder electrospindle designed to be coupled to the second body, and an automatic connection system of the electrospindle to the second body. The connection system includes a plurality of pins, which can selectively fit into corresponding seats on the second body or on the electrospindle for centering and locking. Each seat has a collet that is shaped and selectively movable along its axis to exert a radial locking/unlocking action on the pin. A method of locking/unlocking an electrospindle to/from a working head.

A newly configured centerpoint drill and a drill attachment device that can be attached to a conventional cordless drill include configurations that require a user's hand to be in direct alignment with the keyless chuck of the drill to enable a user or operator to apply maximum pressure or force during use of a drill to reduce time and effort spent by a user/operator.

A combined type angle head milling cutter is configured to machine mounting faces of an axial bearing. The combined type angle head milling cutter includes an angle head body, a lock nut, first slotted countersunk head screws, a first hexagon socket head cap screw, a first flat key, semicircle seal covers, first angular contact ball bearings, a cutter handle shaft lower adjusting pad, a cutter handle shaft, a cutter handle shaft upper adjusting pad, a bearing cover plate, a first bevel gear, a first spring washer, a second bevel gear, a bevel gear adjusting pad, an orientation shaft, cutter shaft inner-side seal covers, second hexagon socket head cap screws, a cutter shaft outer-side seal cover, a second slotted countersunk head screw, a small seal ring and the like.

An angle head attachment of a machine tool may include a main shaft, a bevel gear, a spindle and at least one idle gear module. The main shaft may be rotated with respect to a first direction. The bevel gear may be configured to convert a rotary force of the main shaft into a rotary force rotated with respect to a second direction substantially perpendicular to the first direction. The spindle may be rotated with respect to the second direction by the rotary force of the bevel gear. The idle gear module may be interposed between the bevel gear and the spindle to transmit the rotary force of the bevel gear to the spindle. The rotary force of the main shaft may be transmitted to the spindle through the at least one idle gear module so that the angle head attachment may have a slim structure.

Disclosed herein is a tool-inclining system, which is characterized in that it is provided with a structure that is simple, compact, and able to operate according to an altogether reliable mode of operation. The system comprises: a base for securing said system to a structure that is to carry said tool, such as a robot arm; a support on which said tool is to be fixed, said support being configured in such a way that said tool fixed to said support defines a working axis (S); a connection member for connection of said support to said base, said member allowing a given angular movement of said support so that said working axis displaces, starting from a neutral position, according to a tilting movement; and fluid countering means or elastic countering means, which act on said support so as to exert an action that counters said tilting movement.

The invention is a boring machine including: a guide rail linearly extending in one direction; a main part slidably mounted on the guide rail; a sleeve extending from the main part in a plane substantially parallel to the guide rail; and a rotatable face plate mounted at a distal end of the sleeve; wherein a deflection-compensating wedge plate is provided between the distal end of the sleeve and the rotatable face plate.

A power tool is provided and may include a motor, an output shaft, a neck portion, and a collar portion. The output shaft may be driven by the motor. The neck portion may be configured to receive a removable attachment accessory. The neck portion may define a first diameter and may include a plurality of indexing features. The collar portion may be supported by the neck portion. The collar portion may include an outer circumferential surface defining a second diameter that is greater than the first diameter. The outer circumferential surface may include at least one recess.

A tool (100) for working the internal bore of a tube comprises a motor (10), having a housing with a rotary output; a housing sleeve (14a) and shaft (22); a first bearing housing (16), having a rotatably journalled first spindle (102), mounted on the housing sleeve; and an end sleeve and shaft connected to a tool head. The motor output drives, along a common axis (1), the housing shaft, first bearing spindle, end shaft and tool head. A change mechanism (56,58) is in the tool head to change direction of said drive to transverse said common axis. An output (60) is adapted to receive a tool bit. Gauge means (18,18) is disposed on said tool head and is adapted, in use, to bear against the bore of the tube and maintain the tool head located radially with respect to the tube axis; and support means (24,24) is disposed on one or more of said housing shaft, first bearing housing and end sleeve adapted, in use, to bear against the bore of the tube and support the tool. A long length of tool can work the inside of long tubes.

An offset-angle extension device for a power tool includes an elongated body having a power tool mounting end and an angle adapter end. A bearing housing with a handle is located between and connected to the power tool mounting end and the angle adapter end. The bearing housing includes a bearing that receives a bit extension rod therethrough. A tool mounting rod extends from the bearing housing to the power tool mounting end and connects to the power tool. The bit extension rod extends from a chuck of the power tool, through the bearing and connects to an offset-angle angle adapter.
