model introduction
CNC lathe is currently one of the more widely used CNC machine tools. It is mainly used for cutting inner and outer cylindrical surfaces of shaft parts or disc parts, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, cylinders, and conical threads. It can also perform grooving, drilling, reaming, and reaming. Hole and boring etc. The
CNC machine tool automatically processes the processed parts according to the pre-programmed processing program. We compile the machining process route, process parameters, tool motion trajectory, displacement, cutting parameters and auxiliary functions of the part into a machining program list according to the instruction code and program format specified by the CNC machine tool, and then record the contents of the program list On the control medium, it is then input into the numerical control device of the numerical control machine tool to direct the machine tool to process the parts. The
CNC lathe is composed of CNC device, bed, headstock, tool post feed system, tailstock, hydraulic system, cooling system, lubrication system, chip conveyor and other parts.
parallel double-spindle CNC lathes
CNC lathes are divided into two types: vertical CNC lathes and horizontal CNC lathes. The
vertical CNC lathe is used for the turning of disk parts with a large turning diameter. The
horizontal CNC lathe is used for turning processing of long axial size or small disk parts.
horizontal CNC lathes can be further divided into economical CNC lathes, ordinary CNC lathes and turning machining centers according to their functions.
Economical CNC lathe: A simple CNC lathe formed by reforming the turning feed system of an ordinary lathe with a stepping motor and a single-chip microcomputer. The cost is relatively low, the degree of automation and functions are relatively poor, and the turning precision is not high. It is suitable for turning processing of rotary parts with low requirements.
Ordinary CNC lathe: a CNC lathe that is specially designed in structure according to the requirements of turning processing and is equipped with a general CNC system. The CNC system has strong functions, high degree of automation and machining accuracy, and is suitable for turning processing of general rotary parts. This CNC lathe can control two coordinate axes at the same time, namely the x-axis and the z-axis.
turning center
turning processing center: On the basis of ordinary CNC lathes, C-axis and power head are added, and more advanced machine tools also have a tool magazine, which can control the three coordinate axes of X, Z and C. The linkage control axis can be Is (X, Z), (X, C) or (Z, C). Due to the addition of the C-axis and milling power head, the processing functions of this CNC lathe are greatly enhanced. In addition to general turning, it can also perform radial and axial milling, surface milling, and holes and diameters whose center line is not at the center of rotation of the part. Drilling and other processing of holes.
hydraulic chuck and hydraulic tailstock
hydraulic chuck is an important accessory for clamping workpieces during CNC turning. Ordinary hydraulic chucks can be used for general rotary parts; for parts where the clamped part is not cylindrical, it is required Special chuck is used; spring chuck is required when directly machining parts with bar material. For parts with a large ratio of axial size to radial size, it is necessary to use a live center mounted on a hydraulic tailstock to support the end of the part to ensure the correct processing of the part. The tailstock has ordinary hydraulic tailstock and programmable hydraulic tailstock.
CNC bearing lathe
universal tool holder
CNC lathe can be equipped with two tool holders:
special tool holder: developed by the lathe manufacturer itself, the tool holder used is also special. The advantage of this tool holder is low manufacturing cost, but lacks versatility.
Universal tool holder: The tool holder is produced according to certain general standards (such as VDI, German Engineers Association). CNC lathe manufacturers can choose and configure according to the functional requirements of CNC lathes.
milling power head
CNC lathe tool holder installs the milling power head to greatly expand the processing capacity of the CNC lathe. Such as: using a milling power head for axial drilling and milling of axial grooves.
CNC lathe tool
when turning parts on the CNC lathe or turning machining center, it should be based on the lathe tool holder structureAnd the number of tools that can be installed, reasonably and scientifically arrange the position of the tool on the tool holder, and pay attention to avoid interference between the tool and the machine tool, the tool and the workpiece, and the tool when the tool is at rest and working. The
machine tool composes the
host, which is the main body of the CNC machine tool, including the machine body, column, spindle, feed mechanism and other mechanical components. It is a mechanical part used to complete various cutting processes. The
numerical control device is the core of the numerical control machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software, used to input digital part programs, and complete the storage and data of input information The transformation, interpolation calculation and realization of various control functions.
drive device, which is the drive component of the CNC machine tool actuator, including the spindle drive unit, feed unit, spindle motor and feed motor. Under the control of the numerical control device, it realizes the spindle and feed drive through the electric or electro-hydraulic servo system. When several feeds are linked, the processing of positioning, straight line, plane curve and space curve can be completed. Z1z
auxiliary device, some necessary supporting parts of the index control machine tool, to ensure the operation of the CNC machine tool, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange tables, CNC turntables and CNC indexing heads, as well as cutting tools and monitoring and testing devices.
programming and other ancillary equipment can be used to program and store parts outside the machine.
Since the Massachusetts Institute of Technology in the United States developed the world’s first CNC machine tool in 1952, CNC machine tools have been widely used in the manufacturing industry, especially in the automotive, aerospace, and military industries. CNC technology is used in both hardware and software. In terms of development, there is rapid development.
