PCD and CBN tools - Guhring

Advantages of PCD and CBN toolsPowerful and economicalTools with PCD and CBN cuttingedges are the ideal solution fordifficult-to-machine, highly abrasivematerials. These tools achievehighest quality and economicefficiency. The result: Long tool life,highest surface quality, optimalprocess reliability and repeatability.CFK is probably the most suitablefuture material applied in the aircraftindustry thanks to its high rigidityand low weight. A consequenceof this development is the difficultmachining. The abrasive wear leadsto a visible rounding of carbidecutting edges within a short time(fig. 2). This results in the fibres nolonger being cut but squashed andthen being ripped from the laminate(delamination).The range of application of ourPCD tools begins with applicationsthat have the highest demands onsurface quality.However, in order to take fulladvantage of their performancepotential, the customer‘sproduction must fulfil certainminimum requirements. Thisincludes applying the tools on rigidand vibration-free machines as wellas highly accurate spindle bearingsor slide ways respectively.Figure 1: PCD toolConvincing, wear-resistant diamond cutting edgePCD tools do not display the typicalinitial wear (fig. 1), but guaranteeno delamination tendencies duringthe machining process thanks to theextremely resilient diamond cuttingedge.Figure 2: CarbideVisible rounding of cutting edge after short time8 GUHRING PCD and CBN tools
