## Description

Normally Open Mach3 CNC Automatic Tool Sensor Gauge Changer CNC Z Axis Probe Tool Touch Sensor Setter Setting 4 Wires for CNC Router Engraver Machine

## Features

- 【Description】The tool setting instrument is a special tool setting instrument for the engraving machine machining center machine. The output signal of the tool setting instrument is received by the numerical control system and then the tool length setting, tool wear detection and tool breakage are detected by the program control. In the case of no vibration and malfunction, the thermal deformation of the machine can be corrected according to the rated voltage and current and the specified speed.
- 【Parameter】This is a normally open 4-wire high-precision tool setting instrument with a stroke of 5mm. The positioning accuracy is 0.001mm, the contact life is up to 3 million times, the contact force is 1.5N, and the contact rating: DC24V 20mA.
- 【Material】The housing material of this tool setter is made of 4S grinding grade material. The bottom magnet design can be directly connected to the machine and firmly adsorbed to the body. The contact material is made of super hard alloy, the design is exquisite and the installation is simple.
- 【Feature-1】This tool setting instrument is designed with dustproof and waterproof structure, which can still have strong durability under the condition of coolant and iron filings. It does not need a built-in amplifier and will not be caused deviations by the location temperature and power supply voltage fluctuations of the tool setting instrument, which can be directly input to the NC program.
- 【Feature-2】The tool setter will send out an alarm signal in time when it is over-travel to avoid other troubles caused by equipment operation. Moreover, the tool setter has strong anti-interference. The protruding sharp corner of the tool directly touches the tool tip related to the machining size, detects its value and size, and outputs the signal. It has higher accuracy than the average value obtained by converting the amount of light and electricity.
