Turning Flashcards
What is turning
single pooint cutting tolol removing material from rotating work peice to form a cyllinder
where is turning preformed
Lathe
what are the 11 different parts of the lathe and where are they located
Head stock
tail stock
Spped controls ( headstock)
feed controls (headstock)
Bed ( tail stock)
Spidle (headstock)
carriage
tool post ( carriage)
ways
threaded lead screw
cross slide (carriage)
what is the headstock for
hold one end of work peice
is hollow
controls spindle lead screw and feed screw sppeds
what is the purpose of the carriage
holds/ controls actiity of te the cutting tool
what is the purope of the rack
hanfdd feeding
what is thhe purpose of the lead screw
for threading
what is the purpose of the feed rod
power feed
what are the cliucth conttrols for
forward reverse and stop
what is the purpose of the tail stock
supports tyhhe other end of workpeice ( if requires)
can be used for drilling and reaming
slides along bed
what is 3 components of lathe sizing and there defintions
swing- max diametre of workp[eice
max distance between centres: distance between the centre of the hed stock to tail stock
spindle bore- max bar diameter that will fit through the headstock
what are the differnet tool pots
quick change tool post
4 way turret
latern tool post
wat is the quick change tool post
40 positions at 9 eg increments
easily ajustable tool height
what us a 4 way turret
can hold multple tools
very hard to set tool hights
what are the 6 metthods of holding work
chucks
collet
face plate
live/dead centre
drive dog
mandrel
what are the 3 different types of chucks and what makes the,m special
3 jaw- self centrering jaws
4 jaw- bindependant jaws
6 jaw- self centreing jaws
what are. the advantages of a collet
better tool clearence
better workpeice contact
less mass = less energy
avaliable for square/hex bar but custom shapes are possible
what are the disadvantages of a collet
only suitable for small diameters
small range
need a different collet for each size of bar stock
