It tells in detail and shows how to make a Morse cone on a lathe, how to provide an exact Morse cone angle. The manufacture of a Morse cone is shown on the example of making mandrels with a Morse 1 cone for drilling chucks.
To make a cone, it is necessary to turn the upper slide to an angle of 1 ° 25´43´´. The problem is that the Morse taper angle is set to the nearest second, and for lathes, the reading scale has a division value of 1 °. The machine cannot provide accurate angular dimensions. But on the machine it is possible to make an exact feed over the limbs and to make accurate measurements on the indicator. Therefore, the angle can be provided indirectly by specifying linear values.
For an angle of 1 ° 25´43´´, the sine is 0.025. 48 mm feed is selected for this machine and this chuck. Then it is necessary to achieve such a position of the upper sled, when the condition will be satisfied: 48 mm of stroke and 1.2 mm of lateral displacement along the indicator. This will mean that the slide is rotated at an angle of 1 ° 25´43´´.
When the position of the sled is set, start sharpening the cone. The finished cone is checked for paint using a cone KM 1 and the fit of the cone is monitored. It is seen that the imprint is good everywhere.
Thus, setting the angle of rotation of the upper slide on the indicator allows you to sharpen the cone with good accuracy.
