What is a bench drill? Bench drills are small drilling equipment, and the general processing range is below 25MM. The height is generally below 1.5 meters. Most of the height is 1 meter, which is mostly placed on the work surface, and the power transmission is mostly belt transmission. It is mainly used for small and medium-sized parts. It is used in mechanic workshops and machine tool repair workshops such as drilling, reaming, reaming, tapping, and scraping. Compared with the same type of machine tools at home and abroad, it has low horsepower, high rigidity, high precision, good rigidity, easy operation and easy maintenance. Features. The bench drill is powered by a motor and transmitted to the main shaft through a tower pulley through a variable speed. The outermost part of the main shaft is a sleeve that does not rotate and can only move linearly. There is a rack structure on it, which cooperates with the gear to form a longitudinal feed. Mechanism, the main shaft is installed in this sleeve, the main shaft can freely rotate in the sleeve, but the up and down movement of the sleeve will drive the up and down movement of the main shaft, the innermost one is longer. Use of bench drill Bench drills can be drilled and drilled, fixed on the tool table, which is more stable and stable, and the accuracy and accuracy can be higher. It is a processing machine. It is a sliding spline. The spindle can move freely up and down on the spline, but it must be connected with the spline. Rotating together, a hollow tower pulley is fixed on the upper end of the spline, and the power of the drill bit is transmitted from here to the main shaft through the spline.   Precautions for use of bench drill    1. Wear protective glasses and prescribed protective equipment when using a bench drill. It is forbidden to wear glove.    2. When drilling, the workpiece must be clamped and clamped firmly with pliers, clamps or iron. When drilling thin workpieces, the board must be underneath.    3. It is not allowed to use gauze to remove iron filings during drilling, nor to blow with mouth or wipe with hand.    4. At the beginning of drilling or when the hole is to be drilled, apply light pressure to prevent the workpiece from turning or throwing out. If necessary, add water to cool the drill hole.    5. During work, the work piece should be placed upright and the force should be even to prevent the drill bit from breaking.
