The new tool presetter, which is being researched and developed recently, is not only limited to tool preparation, but is an important part of the overall function of the automated production system. It can be used with counting scales, laser length measuring systems, and tool identification systems. The production management system is used in combination to complete the transmission, calculation, and recording of measurement data.
(1) From measurement to data management
The tool presetter is a measuring device that can pre-adjust and measure the tool nose diameter, clamping length, and input tool data into the NC program of the machining center. With the widespread use of NC machine tools equipped with multi-tool automatic tool changers, the market for high-precision, high-efficiency tool presetters continues to expand.
In order to achieve high-precision and high-efficiency cutting, many users use the two-sided positioning clamping tool system, and now also develop high-precision tool systems with a diameter jump accuracy of 2 μm or less. In order not to reduce the starting rate of the machine tool, it is required to complete the pre-adjustment and measurement preparation of the tool outside the machine; also the demand for the online pre-adjusting tool is also proposed.
(2) CCD type high precision tool presetter is becoming the mainstream model
The demand for CNC pre-calibration tools is constantly expanding. Automotive, semiconductor and other industries require tool presetters with higher precision and efficiency. A CCD-type tool presetter that can achieve higher measurement accuracy is replacing the traditional projection tool presetter as a mainstream product.
In order to pursue high efficiency, high precision and high starting rate of machining centers, more and more users use tool presetters equipped with CCD digital cameras as high-precision products, which are easy to use and versatile. The projection tool presetter is used as a standard product.
(3) Pursuing products with versatility and high efficiency
The tool presetting instrument produced by Osaka Industrial Machinery Co., Ltd. is equipped with a CCD digital camera, which can achieve repeatability of ±3μm without the operator's visual adjustment of the curve. Even with contact measurement, the minimum reading value can reach 1μm. The knife holder uses needle roller bearings (patented product), the friction is small, the rotation is light, and the maximum value of the tool can be measured by one rotation, which can greatly improve the working efficiency. Any point measurement, R measurement and angle measurement can be completed by simple operation of the mouse. In addition, by switching the image, the damage and wear of the tool tip can be verified. If the support software is used, the tool data can be transmitted to the machine tool through the PC. The problem of manual input of data is complicated and causes input errors.
