Lathe & CNC Operation SWMS

Lathes and CNC machines perform turning, milling, drilling, and grinding operations at high rotational speeds that create entanglement, swarf ejection, and coolant mist hazards. Manual lathes are particularly dangerous because the rotating workpiece and chuck are exposed to the operator, creating entanglement risk from loose clothing, gloves, and hair. CNC machines operate within enclosed guards but present hazards during setup, tool changes, and first-article inspection when doors may be opened. Metalworking fluid mist from flood coolant systems causes occupational asthma, dermatitis, and hypersensitivity pneumonitis in workers with sustained exposure.

section 26a binding

Yes — effective 1 July 2026. Non-compliance is admissible as evidence of breach.

Hazards

HazardConsequenceLikelihood
Entanglement in rotating chuck, workpiece, or spindleScalping, amputation, deathPossible
Swarf ejection at high velocity during machiningEye injuries, lacerations, embedded metal fragmentsLikely
Coolant mist inhalation from metalworking fluidsOccupational asthma, hypersensitivity pneumonitis, dermatitisLikely
Workpiece ejection from chuck due to inadequate clampingProjectile impact, fatal head injuriesUnlikely
Hand contact with rotating cutting tool during CNC setupLacerations, finger amputationPossible
Noise exposure from machining operationsNoise-induced hearing lossLikely

Controls (Hierarchy of Controls)

Ensure all CNC machines have interlocked guard doors that prevent operation when open
Prohibit loose clothing, gloves, jewellery, and loose hair near rotating lathe components
Install chuck guards on manual lathes to contain workpiece ejection and swarf
Provide mist extraction systems on all machines using flood coolant to control metalworking fluid mist
Implement a metalworking fluid management program with concentration monitoring and biocide treatment
Use safety chucks with workpiece clamping verification on all manual lathes
Lockout and tagout machines during tool changes, setup, and maintenance
Provide impact-resistant safety glasses and face shields for all machining operations
