Standard Safety features for CNC Machining Centers
Gantry Guard - Single Table Machines
Gantry Guard - Twin Table Machines
The Gantry Guard delivers superior protection for single-table traveling-table CNC machines. Built with robust steel tubing, it encloses the work zone ahead of the gantry and shields operators from rapid machine movements. Securely attached, the guard features an emergency stop button for immediate response to hazards. Its steadfast presence ensures continuous safety and keeps the work area off limits during operation.
Note: This standard feature is not compatible with the Material Handling System (MHS), so users should consider alternative options if the MHS is integrated into the workflow.
The Gantry Guard for twin traveling-table machines delivers enhanced safety by offering all the protection features of the single-table version, plus expanded coverage for both left- and right-hand work zones. Each table benefits from its own frame guard, ensuring comprehensive shielding. The system adds an extra emergency stop button, improving operational safety. The fixed gantry guard effectively protects against high-speed motion of head assemblies, maximizing operator safety.
Safety Light Beam for Traveling Gantry
Safety Tape Perimeter
The Safety Light Beam system stops the machine if any object disrupts the beam. Its two emitter-receiver pairs cover the machine's front and rear. As the gantry moves, the beam follows, ensuring continuous monitoring. If the beam is broken, the machine enters feed hold mode and stops. To resume, remove the object and clear the alarm on the Human-Machine-Interface (HMI).
The Safety Tape Perimeter is a high-visibility, yellow-and-black-striped tape that marks the work zone around the machine. This safety feature visually indicates the machine's active area, serving as a clear warning to operators and personnel to maintain a safe distance. The tape is adhered to the ground and defines the work zone, helping prevent accidental entry into potentially hazardous areas.
Optional safety features for CNC Machining Centers
Light Curtains
Laser Scanners
The Safety Light Curtain is an advanced safety feature that detects any obstruction—meaning something blocking the path—such as a person or object, in front of the machine. For single traveling-table machines, one set of light-curtain components (transmitter, which sends an infrared beam; receiver, which detects the beam; and reflectors, which help direct the beam) is installed to monitor the right, left, and front sides. Twin-table machines use two sets of light curtain kits, each covering one side and the front of both tables, enabling pendulum processing mode, which allows one table to be loaded while the other processes. If the light curtain is disrupted by anything, the machine enters feed hold mode, stopping movement until the object is removed and the alarm is cleared from the HMI (Human-Machine Interface), the operator’s control screen. This system further enhances operator safety and prevents machine damage from accidental entry into the active work zone.
The Keyence Safety Laser Scanner System is an advanced optional safety feature that provides a large detection area per unit, ensuring comprehensive coverage of critical zones around the machine. Its dynamic drawing function allows marking specific areas for detection, enhancing the system’s flexibility. Multiple units can be incorporated to cover several zones simultaneously, making it ideal for complex machine layouts. The system’s target-discrimination capability ensures it can accurately distinguish between people or objects and non-hazardous items, such as dust, minimizing false alarms. Additionally, the system can be configured to record events, providing valuable data for safety monitoring. If a person or object enters a designated detection zone, the system immediately activates the feed hold mode, halting the machine’s motion and preventing potential accidents. To resume operation, the obstruction must be removed, and the operator must clear the alarm from the HMI, ensuring that the machine operates only in safe conditions.
Pressure Mats
Table Bump Strips
The Safety Mat System is an impact-resistant, pressure-activated safety feature that protects operators from injury during machine operation. The mats are strategically positioned on the floor around the machine to cover key areas of potential risk. For single traveling-table machines, the mats are placed in the front section surrounding the table. In twin-table machines, the mats are divided into two zones, covering the left and right sections of the front area. For traveling gantry machines, the mats cover the entire operator side of the machine. Whenever weight or pressure is detected on the mat, the machine enters feed hold mode to prevent further motion. Resumption of operations requires removing the obstruction and clearing any alarms on the HMI. The mats can also be customized to fit multiple zones and sizes to meet specific customer needs.
The Table Safety Bumper Strips are pressure-sensitive strips mounted on both the front and rear of the table. These strips are encased in a durable elastomer to withstand impact. When the sensor strips come into contact with any object or person, the machine will immediately enter feed hold mode to prevent further motion. To resume the operation, the operator must clear the obstruction and reset the alarm through the HMI. This feature ensures the machine halts quickly and reliably when necessary.
