Очищенную от масла стружку помещают в пресс-форму. Количество порошка металла, необходимое дл заполнени пустот в стружке, определ ют с учетом насыпной плотности стружки, массы стружки, насыпной плотности порошка, осле засыпки порошка осуществл ют прессование. Способ обеспечивает повышение качества поверхности изделий: класс шероховатости изделий по предложенному способу 1U-11, по известному 1-2. 1 табл. СОThe invention relates to powder metallurgy, in particular, to a method for producing products from chip waste. The aim of the invention is to improve the quality of the surface of the products. Oil-cleaned chips are placed in the mold. The amount of metal powder required to fill the voids in the chips is determined taking into account the bulk density of the chips, the mass of the chips, the bulk density of the powder, and the powder is filled in after pressing. The method provides improved surface quality of products: the roughness class of products according to the proposed method 1U-11, according to the known 1-2. 1 tab. WITH
