Boring Machine: Defination, Introduction, working principle,Types of boring Machine, diagram of boring Machine,Chartersketch,Parts of boring Machine, Application, advantage, disadvantage.

Introduction:-

The boring Machine is one of the vertalilc Machine toll used to enlarge already drilled hole.
   Boring operation can be performed on lathe as that of turning where tool is stationary and workpiece is rotating,in case of boring is rotating and workpiece is stationary.






Types of boring Machine:-

1. Horizontal Boring Machine (HBM)    fig 1
2. Vertical Boring Machine (VBM)          fig 2
3. Precision (jig) Boring Machine(PBM) fig 3


Parts of Boring Machine:-

1. Head stock
2. Column
3. Runway
4. End support
5. Table
6. Saddle 

Application of Boring Machine:-

1. Horizontal Boring Machine can be used to drill,bore,rim holes
2. Batch production where workpiece is less
3. Machining types parts like gear boxes and engine block
4. For flat surface 
5. Forming Operation
6. Turning cylindrical surface
7. Boring by tool head
8. Boring by boring bar
9. Taper turning
10. Cutting off and necking

Advantage of Boring Machine:-

1. Efficiency is good
2. Great investment
3. Longer life time
4. No foul odor and no noise pollution
5. Fast cutting speed
6. Make several cut at a time
7. Mass production

Disadvantage of Boring Machine:-

1. Intial cost is high
2. Skilled labour required
3. Offer limited flexibility
4. High backup system is required
5. Offer only fix circular geometry and tunnel diameter

Electric discharge Machine: Introduction,working principle,parts,types of EDM,components,application,advantage,disadvantage,EDM

Image
Introduction:- Electric discharge Machine is the process of metal removal from the work surface due to an erosion of metal caused by electric Spark discharge between the two electrode tool and the work piece. Electrical Discharge Machining is also called or known as Spark machining, spark eroding, burning, die sinking, wire burning or wire erosion. This spark near to 8000 to 12000ยบ C. Parts of Electrical Discharge Machine :- • DC Power supply   •Voltmeter •Ammeter •Tool •Die-electric fluid •Pump •Filter •Servo- controlled feed •Fixture •Table Working of Electrical Discharge Machine :- It consists of an electric power supply, the dielectric medium, the tool, workpiece, and servo control. The workpiece is connected to the positive terminal and the tool is connected to a negative terminal of the DC power supply. An air gap of 0.005 to 0.05 mm is maintained between the tool and the work. The die electric fluid which is non-conductor of electricity is...

Abrasive Jet Machine: Introduction, Working principle, working process,parts, Application, Advantage, disadvantage, diagram with suitable name

Image
Introduction:-   It is the process of impinging the high speed stream of abrasive particles by high pressure gas or air on the work surface through a nozzle and metal removal occurrs due to erosion caused by high speed abrasive particles.       In this Machining,the abrasive particle size is 10-40 micros.      Jet velocity will be 150 to 300 m|sec. And it is used to superalloys. Parts of Abrasive Jet Machine:- 1.  Gas supply 2. Filter 3. Pressure gauge 4. Regulator 5. Mixing chamber 6 . Nozzle Working Principle of Abrasive Jet Machine:- The figure shown is the above Abrasive jet Machining. It consists of a mixing chamber, gas filter, pressure gauge, regulator, and the nozzle. The filtered gas at a pressure of 2 to 8 kgf/cm2 is supplied to the mixing chamber containing the abrasive powder and vibrating at 50 Hz, where it mixes with abrasive particles and then enters into the connecting hose. The abrasive and gas mixture c...
