2. What is lathe
A machine for shaping wood, metal, or other
material by means of a rotating drive which
turns the piece being worked on against
changeable cutting tools.
3. What can be produced using a Lathe
โข Shafts,Bushings,Sleeves,Bolts,Nuts,Pistons,Ra
ms,Pump,parts,Electric motor parts, Aircraft
parts, Train parts, Ship parts.
4. Hazards associated using a lathe
There are multiple
hazards when using a
lathe they can vary from:
โข Clothing are caught or entangled in the moving parts of the lathe E.g. chucks, lead and
feed screws, drive gears and the work piece.
โข Being hit by a lose objects like chuck keys, swarf and tools.
โข Using the wrong tools or using them incorrectly and polishing techniques.
โข Getting hit by a piece of the lathe that was not secured
โข Exposed chuck can cause entanglement
โข Using old or warn tools on the lathe which can cause tool failure or the tools becoming
projectiles.
โข Removing swarf/cuttings from the machining with hands which can cause cuts or
infections.
5. What is a mill
โข A milling machine is a drill designed to
machine metal, wood, and other solid
materials. Can be automated with a computer.
milling machines can be positioned in either
vertical or horizontal to carve out materials
based on a pre-existing design
6. What can be produced using a
mill?
- A mill can be used to produce many
things. An example of some things are;
Brackets, fasteners or they can even be
used to refine features on parts.
7. Hazards associated with using a mill
โข Need to keep hands at a safe distance due to
rotating parts.
โข Eye protection to prevent swarf in your eyes
โข Donโt wear and jewellery in case it gets caught
8. What are the main differences
between a lathe and a mill
โข Lathes spin the material, whereas a milling
machine uses a spinning tool for various
cuttings. A lathe has only 2 axis but a mill can
have 3,4 or 5
