A general road milling machine is an equipment for asphalt pavement maintenance and construction, mainly used to remove surface defects such as bumps, oil waves, mesh patterns, and ruts on asphalt concrete surfaces of roads and urban roads. Grinding down the damaged old road surface before laying a new one is one of the most economical and modern maintenance methods.

由于其設(shè)備工作效率高，施工工藝簡(jiǎn)單，銑削深度易控制，冷再生租賃之后操作方便靈活，操作性好，碾磨舊材料直接回收，在城市市政道路和高速公路養(yǎng)護(hù)工程中得到廣泛應(yīng)用。

Due to its high equipment efficiency, simple construction process, easy control of milling depth, convenient and flexible operation after cold recycling lease, good operability, and direct recycling of ground old materials, it has been widely used in urban municipal roads and highway maintenance projects.

根據(jù)銑削的形式，區(qū)分成冷銑式和熱銑式。冷銑型具有功率大、刀具磨損快、切削材料粒徑均勻等特點(diǎn)。它可以配備灑水裝置來噴水，應(yīng)用廣泛。產(chǎn)品已成為一個(gè)系列，由于增加了加熱裝置，熱銑型更為復(fù)雜，通常用于道路再生。

According to the form of milling, it can be divided into cold milling and hot milling. The cold milling type has the characteristics of high power, fast tool wear, and uniform cutting material particle size. It can be equipped with a sprinkler to spray water, and is widely used. The product has become a series, and due to the addition of heating devices, the hot milling type is more complex, usually used for road regeneration.

依照銑轉(zhuǎn)子的旋轉(zhuǎn)方位，劃分為順銑式還有逆銑式。在銑床運(yùn)行時(shí)，轉(zhuǎn)子的旋轉(zhuǎn)方向與砂輪的旋轉(zhuǎn)方向相同，為正銑型，反之為反銑型。

According to the rotation direction of the milling rotor, it can be divided into forward milling and reverse milling. When the milling machine is running, the rotation direction of the rotor is the same as that of the grinding wheel, which is a forward milling type, and vice versa.

根據(jù)銑轉(zhuǎn)子的位置，劃分成后懸掛式、中間懸掛式和后橋同軸式。后懸架類型是銑削轉(zhuǎn)子懸掛在后橋后部;中間懸掛類型是銑削轉(zhuǎn)子在前后軸之間;后橋同軸類型是銑削轉(zhuǎn)子與后橋同軸布置。

According to the position of the milling rotor, it is divided into rear suspension type, middle suspension type, and rear axle coaxial type. The rear suspension type is a milled rotor suspended at the rear of the rear axle; The intermediate suspension type is milling the rotor between the front and rear axles; The coaxial type of rear axle is the coaxial arrangement of milling rotor and rear axle.

根據(jù)銑轉(zhuǎn)子的工作寬度，可分為小、中、大三種類型。小型銑刨機(jī)的銑刨寬度為300-800mm，銑刨轉(zhuǎn)子的驅(qū)動(dòng)操作以機(jī)械為主，特別適用于占地面積小于100m2的地面加工;中型銑床的銑刨寬度為1000-2000mm，銑刨轉(zhuǎn)子的驅(qū)動(dòng)操作以液壓為主大型銑床的銑削寬度大于2000mm，一般與其它機(jī)床配合使用，用于石膏的仿形，銑床的傳動(dòng)方式以液壓傳動(dòng)為主。

According to the working width of the milling rotor, it can be divided into three types: small, medium, and large. The milling width of a small milling machine is 300-800mm, and the driving operation of the milling rotor is mainly mechanical, especially suitable for ground processing with an area less than 100m2; The milling width of a medium-sized milling machine is 1000-2000mm, and the driving operation of the milling rotor is mainly hydraulic. The milling width of a large milling machine is greater than 2000mm, and is generally used in conjunction with other machine tools for gypsum profiling. The transmission mode of the milling machine is mainly hydraulic transmission.

還有依據(jù)傳動(dòng)方式又能分為機(jī)械式和液壓式。銑刨機(jī)租賃公司的工程說到：機(jī)械工作可靠，維修方便，傳動(dòng)效率高，制造成本低，但結(jié)構(gòu)復(fù)雜，操作不輕，運(yùn)行效率低，牽引力小，適用于淺路塹的小型路面維修工作;液壓式結(jié)構(gòu)緊湊，輕便、柔性、牽引力大，但制造成本高，維修困難，適用于中、大型路塹和路面的深度養(yǎng)護(hù)。

According to the transmission mode, it can also be divided into mechanical and hydraulic types. The engineering of the milling machine leasing company states that the mechanical work is reliable, maintenance is convenient, transmission efficiency is high, manufacturing cost is low, but the structure is complex, the operation is not light, the operating efficiency is low, and the traction force is small, suitable for small road surface maintenance work in shallow cutting; The hydraulic structure is compact, lightweight, flexible, and has a large traction force, but it has high manufacturing costs and is difficult to maintain. It is suitable for deep maintenance of medium and large road cuts and pavements.
