Common faults and maintenance of servo motor system 1. Mechanical oscillation (during acceleration/deceleration) The common causes of such failures are: The pulse encoder is malfunctioning. At this time, check whether the voltage on the feedback line terminal of the speed detection unit has dr...... [Read More]

The machining accuracy of CNC machine tools is ultimately guaranteed by the accuracy of the machine tool itself. The accuracy of CNC machine tools includes geometric accuracy, positioning accuracy, repeat positioning accuracy and cutting accuracy. Geometric accuracy: also known as static accur......

01. The band saw blade tension is too small, causing the saw blade to slip off The first place to check is whether the band saw blade is tensioned. The most common cause of a band saw blade slipping is that there is not enough saw blade tension to keep it under tension. After a long period of ...... [Read More]

01. Cylinder crawling (The oil cylinder has the feeling of beating during the lifting process) 1) It may be that there is air inside during installation. Turn on the machine to adjust the stroke to the maximum to make it move quickly and forcibly remove the air. 2) The position of the oil cyli...... [Read More]

1. Turning The workpiece rotates, and the turning tool performs cutting processing with linear or curved movement in the plane. Turning is generally performed on a lathe to process the inner and outer cylindrical surfaces, end surfaces, conical surfaces, forming surfaces and threads of the wor...... [Read More]

As the name suggests, a horizontal lathe has 4 spindles: the 2 spindles in a sealed cutting environment are cutting while the 2 spindles outside the processing area are simultaneously loading and unloading workpieces. Therefore, the 4-axis lathe of the multi-spindle lathe can achieve almost &#...... [Read More]

The so-called multi-spindle lathe is to use 6 or 8 spindle stations to complete the station conversion through indexing: boring, turning, chamfering, tapping, slotting, drilling and other processing procedures are 6 goods 8 All stations are carried out at the same time, which can realize a hig......

1. Clamping method of cushion elastic gasket When grinding the above-mentioned sheet workpiece on a surface grinder, an elastic clamping mechanism is adopted to enable the sheet workpiece to be positioned and clamped in a free state. A layer of 0.5mm thick rubber is placed between the workpie...... [Read More]

1. The size of the workpiece is accurate, and the surface finish is poor The cause of the failure: the tool tip is damaged and not sharp; the machine tool resonates and the placement is not stable; the machine tool has crawling phenomenon; the processing technology is not good. Solution: Afte...... [Read More]

Grinder is a machine tool that uses abrasive tools (such as grinding wheels, abrasive belts, oilstones, and abrasives) as tools for grinding. There are many types of grinders. In order to facilitate management and use, our country has formulated relevant standards for the classification of gr...... [Read More]
