砂帶機(jī)做為一種常見(jiàn)的磨削拋光設(shè)備,在各個(gè)行業(yè)中有著廣泛的應(yīng)用.從外形,結(jié)構(gòu),大小等方面可分為手持式砂帶機(jī),臺(tái)式砂帶機(jī),立式砂帶機(jī)等,從驅(qū)動(dòng)方式來(lái)說(shuō)可分為氣動(dòng)砂帶機(jī),電動(dòng)砂帶機(jī).從砂帶機(jī)磨削形式上可分為接觸輪式砂帶機(jī),平磨墊板式砂帶機(jī),自由懸空式砂帶機(jī)等.又有簡(jiǎn)單手動(dòng)式砂帶機(jī)以及自動(dòng)化砂帶機(jī),機(jī)器人力控砂帶機(jī)等等。

As a common grinding and polishing equipment, sand belt machines?are widely used in various industries. In terms of appearance, structure, size, etc. they can be divided into hand-held?sand ?belt, desktop sand belt, vertical sand belt machines?etc. From the driving method, they can be divided into pneumatic sand belt, electric?sand?belt machines. From the grinding form of sand belt?machines, they can be divided into contact wheel sand belt, flat grinding plate?sand?belt, free-hanging sand belt machines?etc. There are also simple manual?sand?belt, automated?sand ?belt, robotic power-control?sand?belt machines?etc.　

而砂帶機(jī)廠家在行業(yè)內(nèi)得到越來(lái)越多的應(yīng)用,逐漸在很多工序中替代了傳統(tǒng)的砂輪機(jī)打磨方式,也主要是由于砂帶機(jī)和砂輪機(jī)相比有著以下幾個(gè)優(yōu)點(diǎn):

The sand belt machine manufacturers are becoming more and more used in the industry and gradually replacing the traditional grinding machine?and its?method in many processes. This is mainly because the sand belt machine and grinding machine have the following advantages:

一、砂帶機(jī)使用的砂帶做為涂附磨具,相比砂輪機(jī)使用固結(jié)磨具的砂輪來(lái)說(shuō),屬于一種彈性磨削,能更多的吸收打磨過(guò)程中的鋼性沖擊。

1、The belt used in the sand belt machines?is used as a coating abrasive tool. Compared with the grinding wheels that uses?consolidation?as an?abrasive tools, it is more an?elastic grinder?that can absorb more steel impacts during the grinding process.　

?

二、砂帶機(jī)使用的砂帶因表面磨料植砂方式的特點(diǎn),使得砂帶具有比砂輪更強(qiáng)的切削力,磨削比大大高于砂輪磨削,功率利用率達(dá)到96%,相對(duì)砂輪機(jī)的52%的功率利用率來(lái)說(shuō)更加的節(jié)能。

2、 Due to the characteristics of the surface abrasive sand planting method, the belt used has a stronger cutting force than the grinding wheel. The grinding ratio is much higher than the grinding wheel grinder?and the power utilization rate reaches 96%, which is more energy-saving compared to the power utilization rate of the grinding wheel machine of 52%.

三、砂帶機(jī)相比砂輪機(jī)來(lái)說(shuō),工磨削溫度更低,工件表面不易發(fā)生燒傷,形變,金相變化。

3:、Compared with grinding machines, the grinding temperature of belt grinder?machines is lower, and the surface of the workpiece is less prone to burns, deformation, and metallographic changes.

四、砂帶機(jī)相比砂輪機(jī)來(lái)說(shuō),因?yàn)樯皫П旧碣|(zhì)量較輕,系統(tǒng)的平衡性更易控制,不象砂輪機(jī)在使用過(guò)程中易出現(xiàn)動(dòng)不平衡現(xiàn)象。

4、Compared with grinding wheels, the belt itself is lighter and the balance of the system is easier to control, unlike the grinding wheels that are prone to dynamic imbalance during use.

五、砂帶機(jī)相對(duì)砂輪機(jī)來(lái)說(shuō)磨削線(xiàn)速度穩(wěn)定,不象砂輪一樣隨著使用外徑變化大,磨削線(xiàn)速度降低.在自動(dòng)化的打磨機(jī)構(gòu)中不需考慮磨削位置的補(bǔ)償變化.更利用自動(dòng)化的實(shí)現(xiàn)。

5、Compared with grinding wheels, the grinding linear speed of belt machines is?more?stable and unlike grinding wheels.?The grinding linear speed decreases as the outer diameter changes dramatically?as the grinding wheels. There is no need to consider the compensation change of grinding position in the automated grinding mechanism. It is more utilized to realize automation.

六、砂帶機(jī)相對(duì)砂輪機(jī)來(lái)說(shuō),耗材成本低,種類(lèi)多,可根據(jù)表面效果需要靈活更換砂帶,耗材的使用成本低。

6、Compared with grinding machines, the cost of consumables is low and there are many types?to choose from. The belt can be flexibly replaced according to the surface effect needs and the cost of consumables is low.

七、砂帶機(jī)相對(duì)砂輪機(jī)來(lái)說(shuō)設(shè)備成本低,尤其相對(duì)砂輪磨床來(lái)說(shuō).這是因?yàn)樯皫з|(zhì)量輕,法向磨削力小,振動(dòng)也小.對(duì)機(jī)床的剛性及強(qiáng)度及配裝精度要求遠(yuǎn)低于砂輪磨床。

7、The equipment cost of belt machines is low compared to grinding wheel machines?especially compared to grinding wheel grinders. This is because the belt is light in weight, the normal grinding force is small and the vibration is also small. The requirements for the rigidity, strength and assembly accuracy of the machine tool are much lower than that of grinding wheel grinders.

八、砂帶機(jī)相對(duì)砂輪機(jī)來(lái)說(shuō)安全性更高,因砂帶本身質(zhì)量較輕,磨削時(shí)的剛性沖擊小.工作噪音也小于砂輪磨削.即使砂帶斷裂也不象砂輪碎裂那樣有傷人的危險(xiǎn)。

8、The belt machine is safer than the grinding wheel. Because the belt itself is lighter in quality, the rigid impact during grinding is small and the working noise is also smaller than the grinding wheel. Even if the belt breaks, it is not as dangerous as the grinding wheel.

九、砂帶機(jī)相對(duì)砂輪機(jī)來(lái)說(shuō),工藝靈活性更大適應(yīng)性更強(qiáng).這是因?yàn)樯皫ハ骺梢愿鶕?jù)不同的需要改變打磨接觸形式,能更好的貼合及接觸打磨工作面。

9、 Compared with grinding wheels, belt grinding machines have greater flexibility and stronger adaptability. This is because belt grinding can change the grinding contact form according to different needs?and can be a better fit to the grinding working surface.
