CNC Machine Tool Safety
•All machine tools contain hazards from rotating parts; movement of belts, pulleys, gears, and chains;
high voltage electricity; compressed air; noise; and airborne dust, chips, swarf, coolant, and lubricants.
Basic safety precautions must be followed to reduce the risk of personal injury and property damage.
•Your local safety codes and regulations must be consulted before installation and operation of your
machine and CENTROID CNC control. Should a safety concern arise, always contact your dealer or
service technician immediately.
•Access to all dangerous areas of the machine must be restricted while the machine is in use. Ensure
that all safety guards and doors are properly in place during use. Automatically controlled machine
tools may start, stop, or move suddenly at any time. Do not enter the machining area when the
machine is in motion; death or severe injury may result.
•Personal protective equipment, particularly ANSI-approved impact safety glasses and OSHA-
approved hearing protection must be used. Proper handling, storage, use, and disposal of materials
in accordance with manufacturer's instructions and Material Safety Data Sheets (MSDS, or your local
equivalent) must be followed.
•DO NOT operate your machine or CNC control in explosive atmospheres or in environmental
conditions outside of the manufacturer's specified ranges. Electrical power must meet the
specifications provided by your machine and CNC control manufacturer.
•DO NOT operate your machine or CNC control if any safety systems are damaged or missing.
Excessively scratched or damaged windows and guards must be replaced.
•ONLY authorized personnel should be allowed to operate the machine and CNC control. Improper
operation can cause injury, death, and machine or control damage, and may void applicable
warranties.
•All electrical enclosures and panels MUST be closed and secured at all times except during
installation and service. Only qualified electricians and service personnel should have access to these
locations. Hazards arising from high voltage electricity and heat exist in the control cabinet, and may
exist even after the main disconnect is turned OFF.
•Improperly clamped or fixtured parts; improperly secured tooling; and broken parts, fixtures, and
tooling resulting from machining operations at unsafe feedrates and speeds may result in projectiles
being ejected from your machine, even through safety systems such as guards and doors. Always
follow safe and reasonable machining practices and follow all safety precautions provided by your
tooling and machine manufacturer.
•Ultimate responsibility for safe operation and maintenance of your machine and CNC control rests
with shop owners and machine operators. Before performing any work or maintenance all individuals
should be thoroughly acquainted with the safe operation of BOTH machine toolAND CNC control.
•Shop owners and operators are responsible for ensuring that shop and machine safety systems such
as Emergency Stop and fire suppression systems are present and functioning properly, as required by
local codes and regulations.
