Description

Изобретение относитс к обработке резанием на токарных станках.This invention relates to machining on lathes.

Известен способ обработки деталей на станках токарного типа, сопровождающийс намеренным йагревом инструмента, например резца i. Однако при этом вследствие износа инструмента и наличи геометрических погрешностей самого станка обработанные детали имеют конусность.A known method of machining parts on lathes, accompanied by deliberate tooling, for example cutter i. However, due to tool wear and the presence of geometrical errors of the machine itself, the machined parts have a taper.

Предлагаемый способ позвол ет повысить точность обработки путем уменьшени конусности при точении.The proposed method allows to increase the machining accuracy by reducing the taper during turning.

Достигаетс это за счет того, что температуру нагрева резца регулируют в зависимости от величины конусности в соответствии с соотношением ДЕ.К , где А В - удлинение резца, К - конусност детали.This is achieved due to the fact that the heating temperature of the cutter is adjusted depending on the taper value in accordance with the ratio DE.K, where A B is the cutter elongation, K is the taper of the part.

Нагрев резца осуществл етс при помощи нагревател , питаемого от выходной части трансформатора, включаемого в световую сеть напр жением 220 В. Выходное напр жение трансформатора регулируетс в пределах 100-220 В. Тем самым в процессе резани непрерывно измен етс The cutter is heated with the help of a heater supplied from the output part of the transformer, which is connected to the light network with a voltage of 220 V. The output voltage of the transformer is regulated within 100-220 V. Thus, during the cutting process, the output voltage continuously changes.

на нужную величину удлинение резца. После обработки детали дл быстрого охлаждени резца через нагреватель пропускаетс охлаждающа жидкость (вода).to the desired value of the extension of the cutter. After the part has been machined, a cooling fluid (water) is passed through the heater to cool the cutter.

Обточка деталей с подогревом резца производитс в следующей последовательности .The turning of parts with a heated cutter is performed in the following sequence.

Claims

After machining the first workpiece without preheating the tool, the taper value is measured. From the measured taper value and the processing time of the workpiece, the determined voltage value is determined and set on the cutter heat control device. When processing the second and subsequent blanks, immediately after switching on the longitudinal feed of the machine to the cutter, the installed voltage is applied to the cutter, causing heating and lengthening of the cantilever part of the cutter in accordance with the ratio DB-K. After processing the workpiece, the voltage is released to enable the cooling of the tool. Formula izob Method of turning parts, including chip removal by heating
