The ETC-3F electronic tool setting tool is specially designed for machining on the machine in the machining center, CNC boring and milling machine. The tool setting is characterized by the ability to realize the tool length and diameter. Since the result of tool diameter direction tool setting on the machine tool is closest to the actual working condition of the tool, the effect of this tool setting is even more practical than the dedicated tool presetter. Please read the relevant instructions in our product catalog for the specific structure, accuracy and practical methods of this tool holder. Third, about the picking up of the power supply, cable and signal of the tool Brass Floor Drain,4 Inch Brass Floor Drain,Shower Brass Drain,Anti Odor Floor Drain Brass Kaiping City Jinqiang Hardware Products Co.,Ltd , https://www.kimpowerdrain.com
The ETC-3L electronic tool setter is an upgraded product that adds the wired output function of the tool to the ETC-3F tool setter. It is specially designed to meet the requirements of users who want to automatically implement the tool setting process. For example: CNC Machine tool manufacturers, special machine tool manufacturers and machine tool users with certain technical capabilities. Since the use of this tool holder is not detailed in the product sample, the signal output of the ETC-3L electronic tool setter and how it is connected to the CNC system are as follows:
First, about the ETC-3L function
Static tool length setting (tap, drill, etc.); multi-point rotary tool and single-point tool length setting (disk milling cutter, large tool, etc.); rotary tool multi-point and single-point tool diameter setting (keyway) Milling cutters, masts, etc.; fully automatic measuring cycle program including tool change, positioning and offset correction; tool breakage detection by length or diameter measurement; tool damage detection in sequence can identify broken tools and avoid scrapping of workpieces; The length and diameter are detected to identify the tool and the tool is misplaced. The ETC-3L tool holder has a weak protection structure that can be swung to prevent damage to the product in the event of a collision.
Second, about the output of the signal
There is an XS12JK-4P/Y standard socket at the position near the bottom of the ETC-3L electronic tool holder. Each tool holder is equipped with a four-core cable (5 meters in length or according to user requirements). One end is a standard plug that mates with the tool holder socket. A special circuit is provided inside the tool holder for outputting the state signal of the tool and the tool holder when the tool is placed. To ensure the safety of the tool circuit, the signal is isolated at the port of the output signal by the optical element. The output status signal is: when the tool is not in contact with the tool holder, the working state can measure the output photoelectric coupling signal to be high level (about 5V); once the tool is in contact with the tool holder, the tool will generate sound and light prompts. At the same time, the output photoelectric signal can be measured as a low level.
There is no power supply inside the ETC-3L electronic tool setter. The tool setter needs the user to provide external power supply (5VDC, 30-40mA) through the cable. Four ends are provided on the other end of the cable provided by the tool setter, with identification instructions. It is the positive and negative of the power supply and the positive and negative of the output signal. The pickup of the output signal requires the user to load the resistance on the two signal output lines and control the current through the signal output line to not exceed 30 mA (5 VDC), and the user can obtain the signal by measuring the change in voltage across the resistance.
Fourth, the use of the output signal of the tool
The output signal of the ETC-3L electronic tool setter is mainly used as the numerical control system to perform automatic acquisition of the coordinate values ​​related to the tool parameters and the external interrupt signal for the necessary parameter setting work during the tool setting. The interrupts required by different CNC systems are required. The specific requirements of the signals are not necessarily the same. Taking the FANUC CNC system as an example, the interrupt signal should meet the following requirements: 24VDC, 16mA or more. When using the ETC-3L electronic tool setter, the user should change the output signal of the tool sharpener through an appropriate circuit to meet the interrupt signal requirements of the CNC system input. The specific connection position of the signal input can be known by referring to the CNC system connection manual.
Fifth, on the realization of automatic tool setting
When using the ETC-3L electronic tool setter, the user or the machine tool builder must first fix the tool holder on the machine table and use the standard bar to use the standard tool bar to use the ETC-3F electronic tool setter. The center coordinate value of the knife ring is measured, and the coordinate value of the top surface of the knife ring is measured. Then, by reading the programming manual of the numerical control system, the variable parameters corresponding to the diameter and length of the tool and their address numbers are found, and then the program of the tool setting operation is written by using the macro function of the numerical control system. In the programmed program, the combination of the stepping function and the tool parameter setting function (for example: G31 command in the FANUC CNC system and G40, G41, G42, G43, G44, G49) realizes the automation of the tool setting process.
Sixth, about the protection of the knife
ETC-3L electronic tool setting device is equipped with integral protective cover and steel material, which can protect the tool holder from damage during the cutting process, effectively preventing the damage caused by iron filings during the machining process. Remove the knife and replace it with the protective cover.
The use of automatic tool setting not only improves efficiency, but also eliminates the effects of human factors, which is conducive to ensuring product quality. In particular, automatic tool setting is an integral part of the advanced manufacturing technology being developed, which is conducive to improving the competitiveness of enterprises.
