The arrangement of the shaper machine is made as shown in the figure. It consists of the following parts. #1 Base. The base is the necessary bed or support required for all machines tools.; The base is hollow casting made of cast iron to resist vibration and on which all parts of the shaper are mounted.; It is so designed that is can take up the entire load of the …
As you can see the above diagram of Shaper machine, The tool is hold by Ram and workpiece is fixed over table. When we switch on the power the ram reciprocates with respect to the table that means the cutting tool cuts workpiece material in the forward direction and when moving return there is no cut.
2. Percussion drilling can in principle deal with most ground conditions. Can drill hundreds of feet (one well hand-drilled in China in 1923 was over 4000 feet deep). 3. Can drill further into the water table than dug wells, even drilling past one water table to reach another. 1. The equipment can be very heavy and relatively expensive. 2.

10. Working principle : A jackhammer operates by driving an internal hammer up and down. The hammer is first driven down to strike the back of the bit and then back up to return the hammer to the original position to repeat the cycle. The bit usually recovers from the stroke by means of a spring. The only energy involved in making a jackhammer pound up and down is …
