AiVibeCNC Lathe (Turning Centre)
A CNC lathe rotates the workpiece in a spindle while a turret-mounted tool moves along the X (radial) and Z (axial) axes. Turning centres add driven tools, a C-axis and often a Y-axis or sub-spindle for complete machining.
In turning, the workpiece is held in a chuck, collet or between centres and rotated by the main spindle, while the control moves the cutting tool radially in X and axially in Z. Tools are held in an indexing turret. Turning centres add live, or driven, tools and a C-axis that positions the spindle so features such as cross holes and flats can be milled; Y-axis travel, sub-spindles and multiple turrets allow complete machining in one cycle. Swiss-type lathes move the bar through a guide bushing, which suits small, long and slender parts.
CNC lathes produce shafts, pins, bushings, flanges, fittings, valve bodies and other rotationally symmetric parts in industries from automotive to medical devices. Bar feeders, part catchers and robots allow long unattended runs.
Lathe programs commonly use constant surface speed so the spindle speed rises as the diameter falls, which makes a programmed maximum spindle speed essential. Chuck gripping force falls at high speed because of centrifugal force, so speed limits for the chuck and workholding in the OEM documentation must be respected. Tool nose radius compensation is needed for accurate tapers and arcs. Safety requirements for turning machines are covered by ISO 23125.
Key points
- The workpiece rotates while the tool moves in X (radial) and Z (axial)
- Turning centres add live tooling, a C-axis and often Y-axis or a sub-spindle
- Swiss-type lathes use a guide bushing for small, slender parts
- Constant surface speed needs a programmed maximum spindle speed
