Affordable Non Contact Laser Tool Setter

Laser tool setter description

■ The passage of a tool into the beam causes a reduction in laser light seen at the receiver, from which a trigger signal is generated. This latches the machine position at that instant, providing the information to determine a tool’s dimension. With approaches from several directions, tool geometry can also be accurately determined. These systems can also be used to detect broken tools, by rapidly moving the tool into a position where it should intersect the laser beam, if light reaches the receiver, the tool tip must be missing.
■ The non-contact laser beam can check very small tools quickly, reliably and without collision risk. Even the latest high hardness brittle cutting materials can be measured with this laser tool setting instrument system.
■ Because the tool is measured at the rated speed, the errors of tool, spindle and tool holder are all detected and can be corrected directly.

Innovative laser technology

■ The CNC system turns on the laser system through three enable signal lines.

■ The transmitter signal activates or disables the transmitter and turns the laser beam on or off. In order to minimize power loss (heating) and improve the available time, the laser diode can only be turned on during the measurement cycle.

■ When the receiver is enabled, the operating mode of the laser shutter is determined according to the corresponding measurement cycle.

After the transmitter and receiver are enabled, if the light received by the receiver is at least 75% of the maximum value, the output signal of the laser system is used as the trigger signal.

Laser Tool setting protective design

Mechanical protection

The lens of the laser system is strictly sealed through the antifouling gate of the mechanical sealing system to avoid the intrusion of coolant and chips. Only when measuring, the sealing system allows the optical system to emit a beam. The gate is pneumatically driven by a compressed air device.

Air sealing

The transmitter and receiver of laser light barrier are protected by ultra clean sealing air of compressed air device. It can effectively protect the optical system from splashing coolant
