In construction machinery industry, some require that the traditional processing technique of higher longaxones parts is rough turn-smart car-thick
Several procedures such as mill-fine grinding.The polish of part finished surface is essentially relying on additional grinding machine and is realized with wheel grinding, and
The slender rod type part very big for some draw ratios, the such as piston rod of all kinds of hydraulic cylinders, will be received using plain wheel grinding
The restriction of the dynamic range of work, and because of the hardness is bigger of emery wheel, and contain impurity inside emery wheel, when in use, not only affect to add
Work precision, and axial workpiece can be also destroyed when serious, cause axial workpiece to scrap.Sbrasive belt grinding is just fine with its significant advantage
Appear foot, be ground relative to traditional grinding wheel cylindrical, endless abrasive belt is exactly enclosed within contact wheel and tensioning wheel by sbrasive belt grinding technique
It is cylindrical on, in the state of tensioning, make the abrasive band surface extremely delayed contact with the workpiece machining surface of high speed rotation, and one
Under fixed pressure effect, with a kind of process that the Relative friction motion for producing is ground to surface of the work.
Abroad, some industrially developed country developing rapidly due to all kinds abrasive belt grinding machine, the function of sbrasive belt grinding
Far beyond for the scope such as eliminate rust, roughly grind, polishing, machining accuracy is near or above the quality of wheel grinding.According to phase
Pass data is introduced, the yield ratio about 1 in the annual emery wheel in the U.S. and abrasive band:1, in famous Machinery Enterprises CatePiller
Company, sbrasive belt grinding just occupies an important position.In China, sbrasive belt grinding lathe is applied to before rust cleaning, deburring etc.
Operation of the phase without required precision, and it is few to be applied to usage quantity in terms of grinding is particularly high-precision grinding.Chinese patent is disclosed
A kind of external cylindrical superfinishing machine [Application No. 201510678151.7], including frame and workbench, workbench is provided with laterally leads
Rail, horizontal slide unit, traversing driving device, longitudinal rail, longitudinal slide unit and vertical shift driving mechanism；The side of horizontal slide unit is provided with

State is easily controllable, and the such as abrasion such as contact wheel 10, driving wheel, tensioning wheel of all pivoting parts is minimum, in addition the elasticity mill in abrasive band
Cutting effect can greatly mitigate or absorb vibration and the impact that grinding is produced, and grinding speed is stable, sbrasive belt grinding surface of the work matter
Amount is mainly manifested in that surface roughness value is little, and residual stress state is good, and surface changes without microfissure or metallographic structure
Phenomenon.So sbrasive belt grinding is very beneficial for strengthening workpiece surface, workpiece fatigue strength is improved.
Sbrasive belt grinding low cost, this is mainly manifested in, and sbrasive belt grinding equipment is simple, and abrasive band light weight grinding force is little, is ground
Vibrate in journey it is little, to lathe rigidity and intensity requirement all be far below emery wheel grinding machine.Sbrasive belt grinding is simple to operate, and non-cutting time is few,
Operation is very easy, from adjustment abrasive band is changed to the clamping of workpiece to be machined, can complete in a short period of time, sbrasive belt grinding
It is very safe, noise and dust it is little and easily controllable, environmental benefit Deng does not have the danger hurted sb.'s feelings.Due to being rubber contact wheel
10, the rigid shock that sbrasive belt grinding will not be as wheel grinding to workpiece, so processing noise very little.
From the angle of environmental protection, sbrasive belt grinding is extremely to be worthy to be popularized, and sbrasive belt grinding technique is flexible, strong adaptability, using sand
Band grinding can easily solve some unmanageable parts, the such as axial workpiece of overlength, super large.
Specific embodiment described herein is only explanation for example spiritual to the present invention.Technology neck belonging to of the invention
The technical staff in domain can be made various modifications to described specific embodiment or supplement or replaced using similar mode
Generation, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
