A pipe cutting machine comprises a clamping device for holding a pipe to be cut and a pipe cutting apparatus for cutting the pipe by revolving a rotating disc-like cutting blade around the circumferential surface of the pipe held by the clamping device. The pipe cutting apparatus is provided with a revolution motion member of an annular shape rotatably supported by a support member secured to a main frame thereof for revolving a cutting blade around a pipe to be cut; an arm pivotally supported on one side surface of the revolution motion member at one end thereof and rotatably carrying the cutting blade at the other end thereof; a swing motion member of an annular shape rotatably supported by the support member in axial alignment with the revolution motion member for swinging the arm; a rotation motion member of an annular shape rotatably supported by the support member in axial alignment with the revolution motion member for rotating the cutting blade; and plural motors mounted on the main frame for respectively rotating the revolution motion member, the swing motion member and the rotation motion member through driving belts.

When a bonded substrate stack prepared by bonding a first substrate in which a single-crystal Si layer is formed on a porous layer, and an insulating layer is formed on the single-crystal Si layer to a second substrate is to be separated at the porous layer, serrate defects at the peripheral portion of the separated substrates are prevented. A fluid is ejected from an ejection nozzle (112) and injected into the porous layer of a bonded substrate stack (30) while rotating the bonded substrate stack (30) about an axis (C) in a direction (R), thereby separating the bonded substrate stack (30) into two substrates at the porous layer. When the peripheral portion of the bonded substrate stack (30) is to be separated, the ejection nozzle (112) is located within a range (B).

A tamper indicating closure comprising a base wall and a peripheral skirt having an internal thread adapted to engage the threads of a container wherein a tamper indicating band is provided on the skirt by a plurality of circumferentially spaced bridges. The band includes portions adapted to engage an annular bead on the container. The bridges are formed by using a primary knife having an interrupted cutting edge to produce a circumferential score in the side wall of the closure leaving spaced connectors or bridges followed by using a secondary knife having a continuous cutting edge to provide a continuous external score line and an accurately dimensional radial thickness of the bridges. In a preferred method and apparatus, the closures engage the successive primary and secondary knives and are moved such that the closures roll relative to the knives.
摘要:
A method of milling a large thread length with a thread milling cutter having a shank and a milling section having a plurality of rows of teeth arranged in each row one after another with at least two adjacent teeth in each row being separated, in an axial direction by a missing tooth space, with the method including positioning the cutter in a bore of a workpiece, with the cutter being adjusted in an axial direction and fed outwardly, forming a portion of the thread by imparting to the cutter rotational, axial feeding, and circular movements, and forming a further portion of the thread by imparting to the cutter a further circular movement corresponding to the tooth missing space, while continuing to impart to the cutter rotational and axial feeding movement.

An used PCB milling cutter reclamation method includes the step of processing the cutting tip and a part of the handle of the damaged PCB milling cutter to form a new cutting tip, the step of processing the end of the handle remote from the new cutting tip to form a round rod, and the step of fastening an end cap to the round rod, keeping the end cap in line as well as in flush with the periphery of the handle.
摘要:
A cutting knife arrangement employs a plurality of cutting knife inserts mounted on a common circular cylinder. Cutting knife inserts are mounted on a holder device secured to the outer periphery of the cylinder. The cutting knife inserts have a rectangular cross-section with each corner edge comprising a cutting edge. By indexing the cutting knife insert, different cutting edges of the same insert can be presented for use in a cutting operation.

A roll of web and a method of making it has a total web width that is divided into n+1 portions by n circumferential slits. Each portion has a width less than the total web width such that the sum of the width of the portions equals the total web width and such that each portion can be individually used as an independent roll of web. The portions are held together such as by a core or an unslit portion of the web at innermost wraps of web.
