lathe is a machine that mainly uses turning tools to cut rotating workpieces and remove excess material. The lathe can also be used for end face, drilling, knurling, slotting, threading and other processing techniques. And CNC lathe machine FANUC refers to equipment controlled by computer equipment and information. The article introduces the structure of the difference between lathe and CNC lathe.
Lathe refers to a general-purpose basic machine tool used to perform various machining operations in any machinery industry. Due to its multiple uses and advanced forms related to computer numerical calculation systems, the direct program executed by the lathe is to remove excess material from the workpiece. Lathe applications may be associated with tools to rotate to perform specific operations and obtain the required dimensions.
Lathes can process various types of workpieces such as shafts, discs, rings, etc., and are often used to process the internal and external rotating surfaces, end surfaces, and various internal and external threads of the workpiece. You can also use the corresponding tools and accessories for processing. Drilling, reaming, tapping and knurling, etc.
What are the main structures of the lathe
Lathe is a widely used type of lathe, accounting for about 65% of the total number of lathes. They are called horizontal lathes because their main shaft is placed horizontally. The main components of the lathe are: headstock, feed box, slide box, tool post, tailstock, bald screw, screw and bed.
What is the difference between a CNC lathe and a lathe
Spindle box: also known as the spindle box, its main task is to pass the rotating motion of the main motor through a series of speed change mechanisms, so that the spindle can get the required forward and reverse rotation at different speeds. At the same time, the spindle box separates part of the power. Transfer the movement to the feed box. The main shaft of the headstock is the key component of the lathe. The smoothness of the spindle running on the bearing directly affects the processing quality of the workpiece. Once the spindle rotation accuracy is reduced, the use value of the machine tool will decrease.
Feed box: also known as the tool feed box, the feed box is equipped with a speed change mechanism for feeding movement. Adjust the speed change mechanism to obtain the required feed or pitch, and transmit the movement to the tool through a polished rod or screw. Frame used for cutting.
Lead screw and polished rod: used to connect the feed box and the sliding box, and transmit the movement and power of the feed box to the sliding box, so that the sliding box can obtain longitudinal linear motion. The screw is specially designed for turning all kinds of threads. When turning other surfaces of the workpiece, only the smooth screw is used, and the lead screw is not used.
What are the main structures of CNC lathes
CNC lathes have similar components to traditional lathes. Nevertheless, it has additional lathe components such as cooling system, chip conveyor and lubrication system to provide higher accuracy and efficiency.
Generally, there are two types of CNC lathes: vertical CNC lathes and horizontal CNC lathes. For disc parts with a large enough diameter, vertical CNC lathes are usually recommended. On the other hand, horizontal CNC lathes are more suitable for processing small discs or parts with long axial dimensions. Taking into account the purpose and function of CNC lathes, it can be further divided into ordinary CNC lathes, economical CNC lathes, and lathe centers.
Compared with lathes, CNC lathes have higher precision and efficiency. At the same time, the CNC lathe can perform various operations, which is not possible with the lathe equipment. The existence of multi-station turret or power turret enables CNC lathes to process oblique cylinders, straight cylinders, worms, grooves and complex workpieces. Technically speaking, CNC lathes are equipped with equipment that fixes the workpiece in a position defined by a pre-programmed machining program.
This article mainly introduces the difference between the structure of CNC lathe and lathe. By browsing the full text, you can understand that CNC lathe has higher precision and efficiency than lathe. At the same time, the CNC lathe can perform various operations, which is not possible with the lathe equipment.
