DVS UGrind DD/DDV
用于新型车辆技术的新款制造技术

DVS UGrind DD/DDV

目前没有任何产品如汽车和其零配件一样受到技术变化的影响。甚至连刹车盘都会受到生产技术必须满足的新要求的影响。

使颗粒物降至最少

汽车引起的颗粒物很大程度上来源于刹车磨损,不管是来源于刹车片还是刹车盘。生产更加耐磨的刹车盘,并且通过特殊硬质图层对摩擦表面进行处理,以便将颗粒物污染程度降到最低。

 防腐措施

虽然电动汽车也装有盘式刹车,但是它却很少被使用。不过它们的表面也与传统车辆刹车一样暴露在相同的天气条件下。所以很快就会引起生锈。这时候便采用覆盖在铸件上的特殊涂层来起到防护作用。随后就需要磨削技术。

低产高效

由碳陶瓷制成的刹车盘的重量只占铸件刹车盘重量的大概10%,它同时兼具更好的耐磨和刹车特性。这种类型的刹车盘也能在DVS UGrind DD/DDV上进行生产。

磨削铸铁刹车盘

通过定制车床工艺磨削传统铸铁刹车盘具有一系列优势。在砂轮磨损格外小,刀具成本相对很低的情况下,还能产生更高的精度和摩擦表面高达99%的接触面。

要点
01

极硬涂层的加工,例如碳化钨、氧化铝、碳化铬

02

磨削砂轮适用寿命长,刀具成本低

03

自动操作模式下的夹具快换

04

整条生产线最大限度的上游自动化和集成

05

精准的轴向跳动和平行度公差,以及大范围接触面

06

与车削相比,铸铁刹车盘磨削具有更高的效率和精度

The basis of the UGrind 800 DD

  • Same basis as the UGrind800
  • Two grinding supporters on the dovetail
  • The workpiece is clamped on the multifunction head or on a spindle and moves to the grinding supports
  • Automatic loading of the panes by robot possible

  • Machining on both sides

  • Machining of the friction ring surfaces on both sides in one clamping operation
  • All shape and position tolerances match each other
  • The counter-rotating movement of the grinding wheels achieves a cross-grinding, which is a quality feature for perfect flatness
  • Time saving -> increase in productivity due to double-sided processing.

  • Plane-parallel grinding of brake discs

  • Through two grinding supports
  • The grinding supports are movable and have a high-performance spindle
  • Grinding wheel diameter from 350mm - 400mm possible
  • Tensioning of the brake disc during machining with the same tightening force as on the car

  • Powerful drive thanks to powerful workpiece spindle

  • More powerful spindle replaces multifunctional head
  • Dressing/sharpening on cylinder between the two grinding supports
  • The measuring station is located on the right-hand grinding support
  • The variant with the more powerful spindle is especially suitable for hard-coated brake discs
