Abstract
Introduction. The paper examines the technological process for producing carbide circular saws. Unlike cutting with conventional tools, sawing is a complex process. The paper indicates the most common types of sawing. Structural spring and tool steels are used in the production of circular saw bodies. Steels alloyed with chromium, vanadium, tungsten, molybdenum and manganese are selected to achieve the necessary physical and mechanical qualities. These elements increase heat resistance, heat resistance and strength of circular saws. Additionally, to alleviate tension and dissipate heat during operation, compensators of diverse configurations are incorporated into the bodies of circular saws.
The aim of research is to describe the process of optimizing the technology for manufacturing circular saws exemplified by LLC PCC «Mahagoni» enterprise.
Research outcomes. The company LLC PCC «Mahagoni» is one of the leading enterprises in the manufacture of carbide circular saws. The company previously produced both monolithic and composite circular saws. Since 2000, the company has been producing only carbide circular saws with external diameters from 160 to 630 mm and internal diameters of 30, 32 and 50 mm with carbide plates made of steel grades VK6, VK8 and VK15. The company manufactures circular saws equipped with cleaning knives composed of carbide alloys. The company attaches the carbide plates to the body using two methods: the teeth are affixed using electrocontact soldering, while the cleaning plates are bonded via induction soldering employing calcined borax flux and L63 solder. Two types of solder are used - tape and wire-shaped. Steel grade 65G, which combines both rigidity and plastic properties, was chosen for the manufacture of circular saw bodies. This steel grade for circular saw bodies, calcined borax flux, and L63 solder yields products with superior physical and mechanical attributes at a moderate cost.
Conclusions. L63 solder containing over 20 % zinc enhances surface wettability, reduces soldering temperature, and increases the strength of the soldered joint.
