Spindle box: also known as the headstock, its main task is to pass the rotating motion from the main motor through a series of speed change mechanisms to make the spindle obtain the required forward and reverse rotations at different speeds, and at the same time, the spindle box separates part of the power Transfer the movement to the feed box. The main shaft in the headstock is a key part of the lathe. The smoothness of the spindle running on the bearing directly affects the processing quality of the workpiece. Once the rotation accuracy of the spindle decreases, the use value of the machine tool will decrease.
Feed box: also known as the knife box, the feed box is equipped with a speed changing mechanism for feeding movement. Adjust the speed changing mechanism to obtain the required feed amount or pitch, and transmit the movement to the knife through a smooth rod or a lead screw. Rack for cutting.
Lead screw and smooth rod: used to connect the feed box and the slide box, and transmit the movement and power of the feed box to the slide box, so that the slide box can obtain longitudinal linear motion. The screw is specially set for turning various threads. When turning other surfaces of the workpiece, only the smooth screw is used, and the screw is not used. Students should distinguish the difference between the light screw and the lead screw based on the content of the slide box.
Slide box: It is the control box for the feed movement of the lathe. It is equipped with a mechanism that converts the rotary motion of the light rod and the lead screw into the linear motion of the tool post. The longitudinal and lateral feed motion of the tool post is realized through the light bar transmission. And rapid movement, the tool holder is driven by the lead screw to make a longitudinal linear movement, so as to turn the thread.
Tool holder: There are two layers of skateboards (medium and small skateboards), bed saddle and tool holder body. It is used to install the turning tool and drive the turning tool to move longitudinally, laterally or diagonally.
Tailstock: Installed on the bed rail, and move longitudinally along this rail to adjust its working position. The tailstock is mainly used to install the rear center to support longer workpieces. Drills, reamers, etc. can also be installed for hole processing.
Bed: It is a large basic part of the lathe with high precision guide rails (mountain guide rails and flat guide rails). It is used to support and connect the various parts of the lathe, and ensure that each part has an accurate relative position when working.
Cooling device: The cooling device mainly pressurizes the cutting fluid in the water tank through a cooling water pump and sprays it to the cutting area to reduce the cutting temperature, wash away the chips, and lubricate the processed surface to improve the service life of the tool and the surface processing quality of the workpiece.
