Description
Technical field
The present invention relates to machining wastes collection technique field, is specially that a kind of machining uses garbage collection lathe.
Background technology
Machining refers to the process of be changed the appearance and size or performance of workpiece by a kind of plant equipment.By adding
Difference in work mode can be divided into machining and pressure processing.The production process of machine refers to make from raw material (or semi-finished product)
Into all processes of product.Include the transport and preservation of raw material for production of machinery, the preparation of production, the manufacture of blank,
The processing and heat treatment of part, the assembling and debugging of product, the content such as paint and packaging.The content of production process is quite varied,
Principle and method the tissue production of modern enterprise system analysis engineering and Instructing manufacture, production process are regarded as one with defeated
The production system for entering and exporting.In process of production, every shape, size, position and property for changing production object etc., makes it
Process as finished product or semi-finished product is referred to as technical process.It is the major part of production process.Technical process can be divided into again
The technical process such as casting, forging, punching press, welding, machining, assembling, manufacturing technology process generally refer to the machine of part
The summation of the assembling technology procedure of tool machining process and machine, other processes are then referred to as supporting process, such as transport, guarantor
Pipe, power supply, maintenance of equipment etc..Technical process is made up of one or several tactic processes again, a work
Sequence several work steps by being made up of.Process is to form the elementary cell of machining work process.So-called process refer to one (or
One group) worker, on a machine tool (or a job site), same workpiece (or simultaneously to several workpiece) is continuously finished
That a part of technical process.Form process be mainly characterized by do not change processing object, equipment and operator, Er Qiegong
The content of sequence is that the work step being continuously finished is walked under conditions of finished surface is constant, machining tool is constant, cutting data is constant
Knife is called impulse stroke, is that machining tool processes the work step once completed on finished surface.Formulate mechanical processing technique mistake
Journey, it must be determined that the workpiece will pass through the sequencing that several procedures and process are carried out, only list master operation title and its
The simple technical process of processing sequence, referred to as process route.Drafting for process route is the total arrangement for formulating technical process, main
It is the processing method for selecting each surface to want task, determines process in the processing sequence on each surface, and whole technical process
Number of number etc..Process route, which is drafted, must follow certain principle.
