In small-scale industries and automobile maintenance shops, there are frequent needs of tightening and loosening of screws, drilling, boring, grinding machine. Huge and complicated designed parts cannot be machined with the help of an ordinary machine and further for every operation separate machine is required therefore increasing the number of machines required and increasing the area required for them to be accommodated and hence overall initial cost required is increased. 

In a single machine all the above specified operation can be carried out, i.e., after drilling, the drill head is removed from the barrel key and the required tools like grinding wheels, boring tool etc., can be attached, and the operation can be performed. By the application of pneumatics, the pneumatic cylinder with piston which is operated by an air compressor will give the successive action to operate this machine. By this we can achieve our industrial requirements.

WORKING PRINCIPLE

The compressed air from the compressor is used as the force medium for this operation. One Single acting and double acting cylinder is used in this machine .The air from the compressor enters into the flow control Valve. Air enters in to the barrel unit through one way and the other way of air enters to the solenoid valve. When air enters to the cylinder 1, due to pressure difference work blank is 41 clamped and when air enters to the other cylinder due to pressure difference drilling operation takes place as the drilling head comes down and drills the work piece. After this operation the cylinder releases the clamping and drilling head comes to its original position.

APPLICATIONS

•  Used in automobile workshops for drilling carburetor holes.
• Used in small scale industries.
• In welding shop for grinding.
• For performing the operations in huge numbers which cannot be done in ordinary machines. Since it’s portable.
• In such places where frequent change in operation is required.

 In the field of small scale industries and automobile maintenance shops it is very usefully for the workers to carry out a number of operations in a single machine. This also reduced the cost involved in the concern.
