Problems solved by technology

However, during the production process of these turning knives, the knife body and the blade are welded, and the materials of the blade and the knife body are different. When welding, there will be a problem of weak welding, which increases the difficulty of welding.
In order to solve the welding problem, blade manufacturers can only reduce the content of hard alloy at

Abstract

The invention discloses a turning tool for machining an ultrathin broad-width polytetrafluoroethylene thin film. The turning tool comprises a pressing knife, a blade and a lower knife body, wherein the blade is fixed on the lower knife body in a detachably movable connection manner; knife slots for mounting and fixing the blade are formed in the lower knife body; locking bolts are arranged on oneside of the knife slots of the lower knife body; and the blade is fixed on the lower knife body through the locking bolts. The pressing knife and the lower knife body are respectively connected and fixed with a lathe through fixing bolts; bolt slots convenient for adjusting fixed positions are respectively formed in the pressing knife and the lower knife body; and the blade is made of hard alloy.According to the turning tool for machining the ultrathin broad-width polytetrafluoroethylene thin film, the blade is fixedly clamped between an upper knife body and the lower knife body through bolts, so that reliable fixing of the blade can be realized, and the problem on welding of a conventional knife body and the blade is solved. The service life of the turning tool can be effectively guaranteed; and furthermore, the tool cost is reduced, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of turning tools, in particular to a turning tool for processing ultra-thin and wide polytetrafluoroethylene films. Background technique [0002] Polytetrafluoroethylene (PTFE) is commonly known as the "King of Plastics". Among various plastics, PTFE has particularly superior characteristics. For example: its heat resistance, low temperature resistance, chemical resistance, electrical insulation and high frequency characteristics are particularly superior, and it also has unique non-adhesion, sealing, low friction and good aging resistance. If carbon black, glass fiber, carbon fiber, ceramic powder, molybdenum disulfide and other fillers are added to the processing of PTFE products, the product will further improve the compressive strength of PTFE, be more wear-resistant, enhance thermal conductivity, and reduce thermal expansion. And many other advantages, but also has creep resistance, chemical corrosion ...
