The CNC horizontal lathe is a machine tool for turning workpieces mainly with turning tools. Drills, reamers, reamers, taps, slabs and knurling tools are also used on the lathe for the corresponding machining.
CNC horizontal lathe do not have a fixed spindle, but use a variety of tool heads mounted on a horizontal toolpost. These machines can accommodate a wide range of shapes and sizes and are designed to keep the workpiece clean during machining by gravity.
CNC horizontal lathe are usually divided into: horizontal lathes and vertical lathes above two types of lathes. Vertical lathes have a horizontal spindle, while horizontal lathes have a longitudinal spindle. But these structural differences have a significant impact on the function of the machine. While horizontal lathes may be popular, the advantages and possibilities of vertical lathes cannot be underestimated.
The CNC horizontal lathe is the kind we often see in the workshop. Its rotates a specific piece of metal in a cylindrical fashion and as the solid rotates, the CNC horizontal lathe machine uses tools to manipulate the material in order to give it the desired shape and form. Such machines also have a larger footprint than vertical CNC lathes. Even the chucks in horizontal CNC machines can hold objects vertically. These types of machines are usually used for lighter materials.
Horizontal CNC lathes offer a high degree of machining accuracy. These machines have better stiffness and vibration absorption and absorb the vibrations that remove deformation from the machine. The vertical machine bed aids chip evacuation. It is able to support cutting for long periods of time, thus simplifying the set-up of the operating tools.
2 CNC horizontal lathe machining accuracy standards
The method often used in control engineering for CNC horizontal lathes is to first build a simplified model that is as linear as possible and then to obtain approximate characteristics of the system on this basis. If necessary, further studies are carried out using more complex models. This step-by-step approach to approximation studies is a common method used in engineering. Mathematical models of CNC horizontal lathe control systems are not all rich control systems that can be treated with linearisation. For certain systems with strong non-linearities, it is better to use non-linear research methods to deal with them.
The current industry standard for machining accuracy of CNC horizontal lathes has professional standards for CNC horizontal lathe lift table machining centres. The standard stipulates that the positioning accuracy of its linear motion coordinates is 0.04 / 300mm, the repeat positioning accuracy is 0.025mm and the milling accuracy is 0.035mm. in fact, the factory accuracy of the machine tool has a considerable reserve, which is about 20% smaller than the error value allowed by the industry standard. Therefore, from the point of view of machining accuracy selection, a normal CNC horizontal lathe can meet the machining requirements of most parts. For parts with higher accuracy requirements, a precision CNC horizontal lathe should be considered.
CNC horizontal lathes are mainly composed of headstock, grinding wheel frame, tailstock and worktable in the production process. The CNC machining bed uses large round holes and shark fin shaped ribs. After long-term use, the machine tool has good dynamic and static rigidity. The table of the CNC horizontal lathe can be divided into upper and lower tables to grind conical surfaces. The machine base and table guideway are made of plastic guideway with low friction coefficient. The table is directly driven by servo motor to make the ball screw move, the movement is stable and reliable. The linear speed of the grinding wheel of the CNC horizontal lathe is less than 35m / s. The overall grinding efficiency is high when used. The bearing of the grinding head is a three-piece dynamic pressure bearing with a large envelope angle, with high rotational accuracy.
