Many different types of lathes, depending on the purpose and structure of the lathe can be divided into: ordinary lathe, single spindle automatic lathes, multi-axis semi-automatic lathe, turret lathe, vertical lathe, profiling and multi-tool l athe and specialized lathe, CNC lathe and so on. Ordinary lathe, turret lathe and vertical lathes as universal lathes.thin section ball bearing
1. Ordinary lathe
Ordinary lathes such different lathe center height and center distance, can be divided into a variety of different specifications, such as the C6132, C6250. Addition to complete a variety of rotary turning of the workpiece, but also turning a variety of threads, such as metric thread, inch thread, the thread of the analog-to-digital pitch thread and face threads. The ordinary lathe has been widely used in machining.china bearing supplier
2. Turret Lathes
In order to adapt to mass production and improve production efficiency, developed on the basis of the ordinary lathe turret lathe. The main difference with ordinary lathe turret lathe structure: turret lathe turre t tool in place the ordinary lathe tailstock, some and rotary turret instead of the ordinary square turret lathe tailstock. Parts can be processed by conventional lathe, turret lathe can be processed, but the hexagonal lathe, thread machining required tap or die. Turret lathe process characteristics, it is suitable for processing more complex shapes trapezoid small parts of the surface. Available turret lathe machining these parts, unique turret installation step required tool and molding tool, followed by the cutting of the workpiece, in Hex car bed knife turning shorten the cutting time. Horizontal and vertical iron block certain extent the types of machine tools, the need to spend more time processing control, and therefore not suitable in single and small batch production.grinding spindle
3. Vertical Lathe
The main feature of the vertical lathe spindle perpendicular to the table and workpiece cl amping workbench. Vertical lathe suitable for the processing of large diameter, short length, the heavy workpiece, This is because in the vertical lathe, the clamping of the parts, is looking more convenient to better withstand the force, and the rotation between the table and the base rail, smooth movement when working, and thus higher machining quality, but such parts on the ordinary lathes and face lathe, is difficult to ensure the quality.
Vertical lathe can be divided into two kinds of single-column vertical lathe double column vertical lathe. Single column vertical lathe generally have a vertical turret and a side head, two turret has a separate feed box, can be used alone or at the same time work for the vertical and horizontal passes. Large vertical lathe specifications, generally two uprights. In order to facilitate the processing double column vertical lathe beams generally have two vertical turret and one side of the turret. Greater double column vertical lat he in both column one on each side of the turret.
4. CNC lathe
CNC lathe lathe evolved, and program control system on the host, the procedure laid down by the program control command machine action to complete the entire process cycle.roller bearing co
CNC lathe now has spread to the microcomputer control, CNC lathes There are two broad categories, one is a simple microcomputer control machine tools, the other for the computer-controlled machine tools. CNC lathe work operations, according to the input program instructions and the calculation result is input to the drive means. Working step member (aspect pallet) control the drive means is in accordance with the instruction operation, the calculation result is input to the drive means, to control the drive means center drive device (stepping motor) driven by the mechanical transmission mechanism, to manipulate the machine work, to achieve a cutting mo tion . In addition, depending on the processing accuracy, the lathe is divided into ordinary lathes, precision lathes and precision lathes. Precision and high-precision lathe, usually it is the basis of the ordinary precision lathe, Geometric accuracy of machines, measures to reduce the effects of vibration and heat sources, and high performance bearings, machine tools with high machining accuracy.big ball bearing
