Repair Swiss Danqing micrometer

Core features and advantages: High precision and high resolution typically have a resolution of 0.001mm (1 micron), and some models can even reach 0.0001mm (0.1 micron), which is much higher than the estimation method of ordinary mechanical micrometers. The measurement results are displayed directly in numbers, avoiding manual reading errors such as parallax and inaccurate estimation, greatly improving the reliability and repeatability of the measurement. Intelligent and multifunctional data output: Most models are equipped with USB or Bluetooth interfaces, which can transmit measurement data in real-time to computers or SPC (Statistical Process Control) systems, achieving automated collection and analysis of quality data. It is an important tool for modern digital factories. Preset functions: capable of relative measurement, data retention, capture of large/small values, tolerance zone judgment (qualified/out of tolerance indication), etc., with powerful functions. Unit switching: One click switch between mm and inch for easy use of different standards. Humanized design of large-sized LCD screen: clear and easy to read digital display. High level protection: usually with IP65 or higher dust and water resistance, it can adapt to harsh environments such as workshop oil stains and coolant. Power saving design: automatic shutdown function, long battery life. High quality material: The anvil and micrometer screw are made of hard alloy, which has good wear resistance; The ruler frame may be made of stainless steel or lightweight alloy, which is sturdy and rust resistant. Efficient and easy-to-use, fast measurement speed, no need to manually rotate the differential cylinder to a specific force, some models have quick action devices that can quickly approach the workpiece. The zeroing operation is simple, and the zero point can be easily set at any position, making it convenient for relative comparison measurements. The product line of typical models and types of Danqing micrometers usually covers various measurement needs: standard type: measurement range such as 0-25mm, 25-50mm, etc. Large digital micrometer: capable of measuring up to 1000mm or even larger, used for measuring large workpieces. Depth digital micrometer: used to measure hole depth, groove depth, and step height. Inner diameter digital micrometer: used to measure aperture and groove width. Three point inner diameter digital micrometer: determines the aperture through three measuring points for higher accuracy. Blade type/thin sheet type: used for measuring special parts such as narrow grooves and thread diameters. Compared with mechanical micrometers, Danqing digital micrometers have traditional reading methods such as digital direct reading, scale and differential cylinder, which require estimation and are prone to parallax. The accuracy/resolution is usually 0.001mm, and higher is usually 0.01mm (requiring estimation up to 0.001mm). Data transmission support is convenient for digital management, but it does not support manual recording. It has multiple functions (preset, tolerance judgment, etc.) and a single (basic measurement) operation speed. It can quickly return to zero and is relatively slow in environmental adaptability. It is dustproof and waterproof, and has strong adaptability. It is afraid of oil stains and dust, and requires careful maintenance. The price is relatively low. It depends on batteries and does not require power supply. Its main application areas include online detection of precision machining workshops such as CNC machining centers, lathes, grinders, etc. Quality Control (QC) and Quality Assurance (QA): Accurate dimensional inspection of finished products or incoming materials. Mold manufacturing and maintenance: Measure key dimensions such as mold cavity and ejector pin. Laboratory metrology: as a high-precision measuring tool. Research and Teaching: Used for experiments and teaching demonstrations that require precise measurements. Selection and use precautions: Accuracy and range: Choose the appropriate accuracy level and range according to your own measurement needs. Protection level (IP): Choose according to the usage environment, and it is recommended to have an IP rating of IP65 or higher for workshop environments. Data interface: If there is a data collection requirement, it is necessary to confirm that the interface type (USB/Bluetooth) is compatible with the existing system. Calibration and maintenance: Regularly use standard measuring blocks for calibration, keep the anvil surface clean, handle with care, and avoid falling and impact. When not in use for a long time, the battery should be removed. Brand and after-sales service: Choose legitimate channels to purchase, ensure product quality and reliable after-sales service, calibration service.
