2.2 Construction of a drilling machine

2017-2-24  Portable drilling machine can be carried and used anywhere in the workshop. It is used for drilling holes on workpieces in any position, which is not possible in a standard drilling machine. The entire drilling mechanism is compact and small in size and so can be carried anywhere. This type of machine is widely adapted for automobile built-up work.

Principle of mechanical automatic control of drilling

1. A double differential gear linked to the cutting head effects autocontrol of the drilling process in either rotary or rotary-percussive machines, and ensures withdrawal of the bit when jammed. 2. A machine with rotary action and autocontrol in terms of the drilling velocity, feed force, and torque on the bit, intended for drilling deep boreholes, can be constructed by using a mechanical
