Flat bed CNC lathes are widely used in heavy-duty turning, and provide reliable, stable and powerful machining processes with high productivity. Heavy-duty and flatbed lathes have extremely high stability, but compared with inclined bed turning centers and vertical lathes, the possibility of tool replacement and indexing is more limited. The larger part/swing frame diameter and longer length make the stable fixed frame and tailstock standard fixtures.
It is generally believed that flatbed CNC lathes are easier to adapt to the loading and unloading of large parts. The "clearance" between the headstock and the bed can also be used to allow increased component swing diameter, which is called a "clearance bed lathe".
Large machines usually have a headstock with a large bore, and some headstocks can be equipped with dual chucks to allow the headstock to pass through.
The length of the bed is usually much more than four meters, and multiple fixing frames can be easily used. However, it should be noted that these are usually "fixed" stabilizing devices, and usually cannot be used in the same way as the hydraulically operated "through" type that is usually used on inclined bed machines or rotation centers (the inclined bed design can be simplified Axial positioning).
Not all flatbed lathes are equipped with a chip conveyor; therefore, always consider the possibility of chip removal. Sometimes front and rear conveyors are a good choice to reduce downtime.
Turning operations can be classified as heavy, requiring high stability, and the tool post design is often preferred over the head design. If the machine is to be equipped with a multi-tooth tool post, then the VDI dovetail (DIN 69881) provides extremely good stability and is still the most robust solution for demanding depths of cut, as well as providing sufficient clamping rigidity for long bars. Sizes 115 and 140 are commonly used; 140 is preferred for heavy boring bars and long bars.
Lathes and CNC machines with flat bed are among the workshop machines that can be used for a variety of machining purposes such as cutting, grinding, turning, drilling, shaping etc. The lathe works with various types of materials such as all kinds of metals. , wood and even plastic. It is one of the best workshop equipment that remains perfect for obtaining items with the right proportions.Thanks to several technological innovations, to meet the industrial requirements, the lathe has been equipped with computerized CNC technology.
A computerized numerically controlled or CNC lathe works with a modern concept, thanks to which the machining can be efficient and monitored. The flat bed CNC equipment is one of the two types of lathes, a flat lathe and an oblique lathe. CNC is the latest technology that works with the help of a computer on which you can monitor the performance of your computer hardware. The CNC lathe consists of two types of CNC flat bed lathes and CNC slanted bed lathes. Both types of CNC lathes are preferred for the enhanced applications they offer.
The CNC technology slant bed lathe and the flat bed lathe differ in terms of lathe bed alignment. The bed of foam is positioned sideways in an oblique bed lathe as it has proved to be very useful in producing simple Z-axis motion. The movement of the moving parts of the machine is stabilized in the oblique bed, which helps maintain accuracy in the machining process. The oblique position of the play promotes work, even under heavy loads. The assembly of the tool, the entire machine bed, and other maintenance roles is easy to perform in a slanted bed. On the other hand, the flatbed equipment comprises a lathe bed in a flat position in which the material must be properly positioned. The flat bed can be selected for design with variations to support the light and heavy metal machining process.
● A flat bed lathe remains ideal to achieve the accuracy of rigid materials, while a skewed bed may be preferred to achieve Z-axis movement during machining
● A flat bed can be preferred for handling lighter and heavy duty materials, where as slant bed can work only for lighter material
● A flat bed is reliable than a slant bed in terms of low power consumption, higher range of productivity, stability and machining.
A slant bed lathe is relatively beneficial in loading, accessing and machining as it works only with lighter materials, whereas flat bed lathe requires the support of a skilled professional who can handle it properly.
