A Metal Lathe is a tool to machine metal by rotating it against a stationary cutting tool.
Makespace owns a Warco metal lathe - a powerful, solidly built machine that can achieve micrometre-level precision.
In contrast to the freehand cutting typical of a wood lathe, a Metal Lathe constrains the cutting tools. This rigidity is how it is able to cut metal with high precision.
What can a Metal Lathe do?
Types of operation:
facing cuts, also known as cross-cutting
turning cylindrical bits
boring an internal hole
centre drilling to make accurate concentric features
cutting at an angle to make a taper or cone
chamfering sharp edges away
screwcutting to make threads
What can you make using a Metal Lathe?
What materials can you machine using the Metal Lathe?
The Makespace metal lathe can machine:
all ferrous (iron-based) materials except hardened steel
aluminium, brass, bronze, and copper
plastics such as Deltrin/acetal, HDPE, Nylon, Acrylic, PTFE
It CANNOT be used to machine e.g.:
glass, stone, or ceramics
hardened steel - it is too tough
fibreglass, Kevlar and carbon fibre-based composites - they produce toxic dust
rubber or similar soft materials
wood - should be turned on the dedicated Wood Lathe instead
The work pieces can be up to 65 cm long and up to 32 cm in diameter.
EXCEPTION: very thin and long material pieces (e.g. 65cm by 5mm diameter nylon) - they cannot be properly supported, which can be dangerous.
