Types of Taper Turning

Type of Standard Taper and their uses :- Machine part & tools having inside or outside taper are standardized to facilitate interchangiability of parts. Tapered surface which follow standard dimensions are called standard Tapers. Standard tapers are adopted by the Indian Standard institution for various tools and machine parts like drills, reamers, milling cutter shanks, arbors, lathe centres etc. The following are the common standard tapers in use. 1)  Morse Taper (MT) 2)  Brown & Sharp Taper (BS) 3)  Jarno Taper (JT) 4)  Metric Taper 5)  Pin Taper 6) Key and Key-ways Taper 7) Jacobs Taper 1)    Morse Taper ( MT)& their uses : It is the most commonly used standard taper in the industry. The Morse taper is denoted by the letters MT. It is a self holding taper. The Morse taper is available in eight sizes (MT0 to MT7). They are MT-0 ,MT-1, MT-2, MT-3 ,MT-4, MT-5, MT-6 & MT-7 . The included angle of Morse taper approximately...

What is meant by taper turning?

Definition of Taper : Gradually increase or decrease in the diameter along with the length of job is called Taper. Taper Turning : Taper turning is a machining operation that is gradually increase or decrease in diameter from one part of a cylindrical work piece to another part is called Taper Turning. Taper can be either external or internal. If a work piece is tapered on the outside it has external taper; if it tapered on the inside, it has internal taper. TAPER ELEMENTS: D = Big diameter d= Small diameter l= length of the taper L= Total length of job α = Half taper angle 2 α = Full Taper angle Expression of Taper and its Conversion: Taper can be expressed by – ·         Giving the big diameter, small diameter and the length of the taper. Conversion : Tan θ = D-d/2L ·         Mentioning the included angle of the taper in degrees. EX: 30° Taper angle ·     ...
