our special machines series have been projected and developed for roller burnishing technology (also called surface rolling), which is used on cylindrical, conical, or disk shaped workpieces. the tool resembles a roller bearing, but the rollers are generally very slightly tapered so that their envelope diameter can be accurately adjusted. the rollers typically rotate within a cage, as in a roller bearing. 我们的特殊设备系列采用了滚柱磨光技术（也叫表面滚压），用于圆柱形，圆锥形或圆盘形工件的表面处理。模具类似于滚柱轴承，但是滚柱一般略呈锥形，使其包络直径可以精确调节。滚柱通常在一个笼子里旋转，作为一个滚柱轴承运转。 the le series is a range of hydraulic precision burnishing machines which are used for super finishing plunge rolling as well as throughfeed operations on cylindrical surfaces, in some cases on slightly conical pieces. this series includes three machine sizes and offers a choice of burnishing force from 400 to 1000 kn, covering a range of diameters from ?=2mm to ?=165 mm, 4 sizes of heads are available: 该le系列是通过切入滚丝和贯穿进给操作在圆柱体表面或略呈锥形工件进行超精加工的一系列液压精密磨光机。这一系列包括三种机械尺寸，并有磨光力范围从400到1000千牛可选，覆盖直径范围从?=2mm至?=165毫米可选，4种尺寸的模具可选： · from 2 mm to 6 mm · from 6 mm to 20 mm · from 20 mm to 40 mm · from 40 mm to 60 mm le60 le100 le150 max pressure(kn) 大压力 400 600 800 max workpiece diameter(mm) 大工件直径 65 100 165 max plunge length (mm) 大进给长度 45 45 60 weight (kg) 重量 1200 1400 1700 product description产品描述 the machine is provided with one head size, chosen by the customer during the order, it can be equipped with special equipment for rolling particular or long pieces (bars). the le series can be equipped with plc or cnc control unit. 此机器只提供一个头部尺寸，由客户在订购的时候选择，它可以为特殊滚丝或长工件（棒）配备特殊设备。le系列可以配备plc或cnc控制单元。 burnishing advantages磨光优势 · outstanding surface quality杰出的表面质量 · high precision高精度 · improved mechanical properties of material提高物料的机械属性 · low cycle time 缩短循环周期 · low cost production per part降低部件生产成
