A thread milling system includes a thread milling machine having a spindle; and a combination tool having a body and a reaming insert, the body having a first end and a second end, the body defining a securing pocket, the reaming insert secured proximate to the second end of the body and within the securing pocket, the second end of the body attached to the spindle.

A method of operating a thread milling machine includes securing a product in a securing mount proximate to the thread milling machine, the thread milling machine having a spindle; securing a combination tool to the spindle, the combination tool having a body and an insert, the body having a first end and a second end, the body defining a securing pocket, the insert secured proximate to the second end at a first side of the securing pocket, the second end attached to the spindle; and rotating the spindle.

An improved method of machines grooves forming Pearson notches in a pattern on hollow shell casings for munitions for at least one of increased functionality and/or performance. Rather than running a broach through a hollow casing, a CNC lathe with a multi-axis tool with cutting implement can precisely locate and form grooves along either an interior or an exterior surface of a hollow shell casing.

A combination tool for a thread milling system includes: a tool mount configured to secure the combination tool on a thread milling machine of the thread milling system; a body connected to the tool mount, the body having a first end and a second end, the body defining a securing pocket; and a reaming insert secured proximate to the second end and within the securing pocket.

The invention relates to a method for preparing the surface of a substrate (100) for the purpose of accepting and holding a coating sprayed by a plasma torch. Said method includes a machining phase and is characterized that it includes the following phases: producing, by means of a machining tool (200), at least one groove having at least one angled edge; offsetting the tool (200) by moving the tool relative to the surface of the substrate (100) in a direction perpendicular to the longitudinal axis of the groove and along a path shorter than the projected length of the angled edge; and using said tool (200) on the angled edge of the groove such as to subject said edge to stress and create another offset groove, and so on and so forth, such that the tool (200) irreversibly changes the shape of the ribs (111, 112, 113, 114) finally obtained between each groove, and said ribs adopt undercut surfaces.

A method and apparatus for processing workpieces to form parts. Tools associated with a multi-spindle machine may be positioned with respect to a plurality of workpieces on a fixture comprising a plurality of platforms and an adjustment system. Each platform may be individually moveable with respect to others in the plurality of platforms about a number of axes. The plurality of platforms may be configured to hold the plurality of workpieces in which each platform may be configured to hold a workpiece in the plurality of workpieces during operations performed by the multi-spindle machine. The adjustment system may be configured to move each of the plurality of platforms about the number of axes independently from the others in the plurality of platforms. The operations may be performed on the plurality of workpieces using the multi-spindle machine and the fixture to form a plurality of parts.

In a method for producing a cavity (14) in a stator of an eccentric screw pump, material is removed in the interior of a stator blank (10) by means of a tool (11). In order that very long stators can be produced in one production operation, the tool (11) performs a rotational motion through a first shaft (12) and an eccentric motion around a second shaft (13), during which the stator blank (10) and the tool (11) are moved toward each other. A device for performing the method comprises (a) a bearing shaft (3) that can be coupled with its drive end to a first drive and that is rotatable around its longitudinal axis by means of the first drive; (b) a drive shaft (4) that can be coupled with its drive end to a second drive and is arranged in a borehole of the bearing shaft (3) and is rotatable around its longitudinal axis by means of the second drive form-fitting and relative to the bearing shaft (3), and (c) a machining tool (5), which is rotationally fixed connected to the machining end of the drive shaft (4) that can be inserted into the cavity and can be driven rotatably via the drive shaft (4) around the longitudinal axis of the drive shaft (4). The longitudinal axis of the drive shaft (4) intersects the longitudinal axis of the bearing shaft (3) at a point or is arranged askew to the longitudinal axis of the bearing shaft (3).
