What are the types of CNC lathes and what are their advantages?
First, according to the lathe spindle position classification:
vertical numerical control lathe. The spindle of the lathe is perpendicular to the horizontal plane, and a circular table of large diameter is used to hold the workpiece. This kind of machine tool is mainly used to process large complex parts with large radial size and relatively small axial size.
(2) horizontal CNC lathe. Horizontal CNC lathes are divided into flat rail Horizontal Lathes and inclined rail horizontal lathes. Its incline rail structure can make the lathe more rigid and easy to remove chips.
Two, according to the type of processed parts are classified:
(1) chuck type CNC lathe. This kind of lathe has no tail seat, suitable for turning disk type (including short shaft type) parts. Clamping mode for electric or hydraulic control, chuck structure with adjustable jaws or not quenched jaws (namely soft jaws).
(2) top CNC lathe. This kind of lathe is equipped with ordinary tailstock or numerical control tailstock, suitable for turning longer parts and disk parts with not too large diameter.
Three, according to the number of tool rest classification:
(1) single tool frame CNC lathe. CNC lathes are generally equipped with various forms of single tool holders, such as four-station horizontal transposition tool holders or multi-station turret automatic transposition tool holders.
(2) double tool frame CNC lathe. The double tool stands of this type of lathe are arranged in parallel or perpendicular to each other.
Four, according to the function of the classification:
(1) economic numerical control lathe. The simple numerical control lathe formed by using stepping motor and single chip microcomputer to transform the feed system of the common lathe has low cost, but the degree of automation and function is relatively poor, and the precision of turning is not high, so it is suitable for the turning of the rotary parts with low requirements.
(2) ordinary CNC lathe. According to the requirements of turning processing in the structure of the special design and equipped with a general numerical control system and the formation of numerical control lathe, numerical control system function is strong, the degree of automation and processing accuracy is also relatively high, suitable for general rotary parts turning processing.
(3) Turning processing center. On the basis of the ordinary CNC lathe, the power head is added, the more advanced CNC lathe with a knife library, can control the three axes. Due to the increase of milling power head, the processing function of this CNC lathe is greatly enhanced, in addition to the general turning can be carried out in radial and axial milling, curved surface milling, the center line is not part of the rotary center of the hole and radial hole drilling processing.
Five, Other classification methods
According to the different control methods of the CNC system and other indicators, CNC lathes can be divided into many kinds, such as linear control CNC lathes, two spindle control CNC lathes, etc.; According to the special or special process performance can be divided into thread CNC lathe, piston CNC lathe, crankshaft CNC lathe and other kinds of.
