General lathe is a horizontal lathe that can process various types of workpiece such as shaft, disk, ring and so on. It is often used to process the inner and outer rotating surface, end face and various internal and external threads of the workpiece. It adopts the corresponding cutting tools and accessories, and can also carry out drilling, reaming, tapping and knurling. Ordinary lathe is the most widely used lathe, accounting for about 65% of the total lathe class, because its main shaft is placed in a horizontal way, it is called the horizontal lathe.

Structure function

The main components of the CA6140 general lathe are: headstock, feed box, slide plate box, tool rest, tail frame, light bar, lead screw and bed.

Headstock: also known as the headstock, its main task is to the main motor from the rotating motion through a series of variable speed mechanism to make the spindle to get the required positive and negative two kinds of steering speed, while the headstock out of part of the power to move into the box. The middle spindle in the headstock is the 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 is reduced, the use value of the machine tool will be reduced.

Feed box: also known as the cutter box, the feed box is equipped with a variable speed mechanism of the feed movement, adjust the variable speed mechanism, you can get the required feed or pitch, through the light bar or lead screw movement to the tool carrier for cutting.

Lead screw and light screw: used to connect the feed box and the slide plate box, and transfer the motion and power of the feed box to the slide plate box, so that the slide

Live center

The crates gain longitudinal linear motion. The lead screw is specially used to turn all kinds of threads and set up, in the other surface of the workpiece turning, only the light screw, not the lead screw.

Slide box: it is the control box of lathe feed movement, which is equipped with a mechanism to change the rotating movement of the light bar and the lead screw into the linear movement of the tool rest. Through the light bar transmission, the longitudinal feed movement, horizontal feed movement and fast movement of the tool rest are realized, and the tool rest is driven by the lead screw to make longitudinal linear movement, so as to turn the thread.

Tool rest: the tool rest component is composed of several layers of tool rest. Its function is to clamp the tool and make the tool feed longitudinally, laterally or diagonally.

Tailstock: the rear center for positioning support, and drilling tools such as drill and reamer can also be installed for drilling.

Bed: the bed body is mounted on the main parts of the lathe, so that they work in an accurate relative position.
