    摘要： The invention relates to a metal-cutting machining process for a semi-finished product having a predetermined shape and at least one machining surface which has the steps: applying a protective foil having a predetermined elongation at break to the at least one machining surface with a predetermined adhesive force, placing a metal-cutting tool in a predetermined position above the machining surface, exerting a predetermined mechanical force in a predetermined direction for a predetermined length of time to the tool for carrying out a metal-cutting process on the semi-finished product and lifting the tool from the at least one machining surface after the predetermined length of time. In order to protect the semi-finished products from damage through the machining residues and at the same time not to impair the drilling performance, according to the invention through the adhesion an adhesive force is produced between the protective foil and the machining surface of substantially 10 N/25 mm and a protective foil is used which has an elongation at break of between 80 and 120%.

    摘要： The multi-purpose plumbing tool is designed specifically for use with copper tubing to enable cutting and preparation of cut ends and associated fittings for soldering on a job site. Basically, the tool includes a frame supporting a motor driven high speed circular pipe saw. A handle and pipe vise structure in turn is pivoted as a unnit to the frame in such a manner that a pipe gripped in the vise can be swung downwardly and forwardly into engagement with the circular saw blade and thereby cut. The same motor driving the saw blade is utilized to drive rotary wire brushes for cleaning the outside of cut ends of the pipe and the inside of fittings. Appropriate deburring and reaming operations are also performed by these rotating structures. Finally, flux applicator heads are provided to treat the cleaned pipe end surfaces and inside the fittings with appropriate flux paste preparatory to soldering, these flux applicator heads being held on the frame and supplied by paste from a cartridge carried in the frame.
