Micro-diameter drill bit is commonly used in modern construction industry, a class of hardware tools, with a small diameter drill, home drilling a number of small-scale installation is particularly simple, but the quality of the drill bit and the stability of the use of performance To a certain extent determines the effect of its use, so in the use of micro-diameter drill bit showing some of the more satisfactory results, then in the course of the process must pay attention to its proper maintenance and care.

First, the daily storage

First of all, small diameter drill bit should be installed in a special package, to avoid vibration collide with each other. To check the concentricity of the spindle and the collet chuck and the clamp force of the collet often, poor concentricity will cause the small diameter small diameter drill bit broken drill and large aperture, the clamping force is not good will cause the actual speed and Set the speed does not meet the chuck and small diameter drill between the slip.

Second, the daily use

Use, remove the small diameter drill from the box should be immediately installed into the spindle collet chuck or automatically replace the drill bit magazine, used up should be immediately back into the box. Remember to ensure that the effect of vacuum drilling is good, because the vacuum wind can reduce the diameter of micro-bit temperature, while taking away the dust to reduce the friction temperature. In addition, the substrate stack includes upper and lower backing plates to be positioned and flattened in a hole-and-slot positioning system on a drilling machine table. The use of adhesive tape to prevent the micro-diameter drill bit in the tape so that the small-diameter drill bit adhesion chip, resulting in chip evacuation and broken drill.

Third, routine maintenance

Always check the spindle presser foot. Presser foot contact surface to be horizontal and perpendicular to the spindle can not be shaken to prevent drilling and hole drilled hole can usually use 40 times stereo microscope to check the micro-diameter drill cutting edge wear, when a long time without the use of micro-diameter drill bit Should pay attention to their maintenance, in case it has not been used for a long time rusting phenomenon.

The above is the science of small diameter drill daily storage, routine use and routine maintenance and maintenance methods, in order to ensure the performance of small diameter drill bit stability and working life, the majority of friends in the course of daily use must be detailed compliance The relevant recommendations of the text, must not carelessness throw free micro drill bit.
