Structural features
- Sturdy and durable materials: The main body of the tool setting arm is generally made of high-strength metal materials, such as aluminum alloy or high-quality steel, to ensure that it will not deform due to collision or vibration in a complex processing environment, affecting the measurement accuracy.
- Flexible joint design: Most tool setting arms have multiple movable joints, which can rotate freely within a certain range, so that the measuring probe can easily reach different positions of various tools to meet diverse measurement needs.
- High-precision sensor: The built-in sensor is one of the core components of the tool setting arm, and its accuracy directly affects the accuracy of the measurement results. High-precision displacement sensors, such as grating rulers or inductive sensors, are usually used to accurately sense tiny displacement changes.
Application scenarios
- CNC lathe processing: In CNC lathe processing, the tool setting arm can quickly and accurately measure the length and radius of the turning tool, helping the operator to quickly complete the tool setting work, reducing the preparation time before processing and improving production efficiency.
- Machining center operation: For machining centers, there are many types of tools. The tool setting arm can accurately measure different types of milling cutters, drills and other tools to ensure that the position and size of the tool are always accurate during multi-process processing.
- Mold manufacturing industry: Mold manufacturing often requires extremely high precision. The tool setting arm can monitor the wear of the tool in real time during mold processing, adjust the tool parameters in time, and ensure the processing quality of the mold.
Advantages
- Improve processing accuracy: By accurately measuring the tool parameters, the machine tool is provided with accurate tool compensation values, which effectively reduces the processing error and improves the processing accuracy of parts.
- Save time and cost: The fast measurement process and convenient data transmission greatly shorten the tool setting time, reduce the downtime of the machine tool, and improve production efficiency.
- Reducing labor intensity: The automated measurement method reduces the tedious operation of manual measurement and reduces the labor intensity of operators.
