Description

Известно, что наиболее у звимым местом резца  вл етс  его вершина. Прочность резца может быть увеличена, если передний угол около вершины сделать отрицательным. При удалении от вершины услови  отделени  стружки облегчаютс , поэтому нет необходимости делать отрицательный угол вдоль всей режущей кромки резца.It is known that the most prominent point of the tool is its tip. The strength of the tool can be increased if the rake angle near the top is made negative. When moving away from the tip, chip separation conditions are facilitated, so there is no need to make a negative angle along the entire cutting edge of the tool.

Дл  увеличени  стойкости резца предлагаетс  располагать заточной круг таким Образом, чтобы проекци  оси его возвратно-пр молинейного перемеш,ени  пересекалась с режущей кромкой, как показано на фиг. 1. В этом случае касательные к вогнутой поверхности на передней грани (фиг. 2) будут иметь вдоль режущей кромки переменную величину. Угол пересечени  проекции оси движени  с режущей кромкой и рассто ние этого пересечени  от вершины задаютс  в зависимости от качества обрабатываемого материала и условий работы .In order to increase the cutter's durability, it is proposed to position the grinding wheel in such a manner that the projection of its reciprocating and rectilinear axis intersects with the cutting edge, as shown in FIG. 1. In this case, the tangents to the concave surface on the front face (FIG. 2) will have a variable value along the cutting edge. The angle of intersection of the projection of the axis of motion with the cutting edge and the distance of this intersection from the top are set depending on the quality of the material being processed and the working conditions.

Предмет изобретени Subject invention

Способ заточки резцов с пластинками из металлокерамических твердых сплавов, отличающийс  тем, что при заточке резец устанавливаетс  таким образом, чтобы проекци  оси возвратно-пр молинейного перемещени  заточного круга пересекалась с режущей кромкой.The method of sharpening the cutters with plates of metal-ceramic hard alloys, characterized in that when sharpening, the cutter is set so that the projection of the axis of the return-straight linear movement of the grinding wheel intersects with the cutting edge.
