Machine Parts

Precautions of a Lathe milling machine: 1.      Switch on machine check its running. 2.      One should ensure that machine is switched off at main switch. 3.      Always machine must be lubricated where it is also should be cleaned. And also should remove all metal chips for machine with particular attention in sideways. 4.      Mount cutters after thoroughly cleaning the bore, keyways and boss faces ensuring that cutter is clear of the surface of the workpiece. 5.      Safety guard must be fixed. 6.      Set up for all controls such as rate of feed, speed of cutter and rate of feed. 7.      Cutting fluid nozzle must be adjusted to right position when coolant is required. 

There are four types of work holding devices is more used such as  1.      Plain Vice:  It is one of the common work holding devices which is hardiest. Plain Vice can be fastened to the table with the jaws or at the right angle to the –T slot.  2.       Swivel Vice:    Swivel vice is as like as plain vice where have only one difference between this two, swivel vice top part can be turned in complete cycle.  3.      Universal Chuck:    It is used for holding the round work piece.  4.      Dividing head:  Diving head used for turning and holding the job so that a number of equal spaced divisions or cuts can be around it. 

Grinding drill bit: The cutting tool used most often in the drill press are twist drills. The flutes of the drill are spiral shape   and as well as carrying savings away   from the cutting edge, they actually from the cutting edges of the drill. As with any other cutting edges of the drill. As with any other drill cutting tool the drill has cutting tool the drill has cutting angles clearance angles and rank angles these angles may need to be changed for the drill to be used on some materials such as gray cast iron, alloy steels or plastics. Precautions of   a grinding Machine: i.                    Must always safety glasses of the operation duration.  ii.                  One should be learnt how to test a wheel for soundness before mounting it.  iii....

Introduction of  grinding machine: Grinding Machine: A grinding machine is a machine which employs a grinding wheel for producing cylindrical, conical or plane surfaces accurately and economically and to the proper shape size and finished.   Grinding machine is a type of machining using an abrasive wheel as the cutting tool. The surface stock is either removed by feed the work against the revolving wheel against workpice.  Power transmission System of a Grinding Machine: Motor   →   Pulley     →   Pulley   → Grinding Wheel. Three essentials in sharpening a twist drill: i.                    Drill point angles must be equal where each is 59   ͦ   and total angle is 118 ͦ. ii.                  Cutting lips ...

Size of shaper machine: The size of shaper machine is determined by its maximum stroke in inches. The workpice is clamp to the table usually in a vice. The cutting tool and the table can move vertically. The table moves longitudinally under the cutting tool.  Drill press : Drill press is used for produced hole in inner surface or internally   which is one types of drilling machine.   Common machine shop operations : Drilling is the one of common machine shop operation such as reaming, counter sinking, counter boring and tapping also be one on a drill press. Operating in the machine quite easier. Power transmission of a shaper machine:  Motor → Pulley   →   Pulley → Gear box→ Pinion→ Pinion                                    ...
