现今纳米(1nm=10~(-9)m)技术领域的研究大多从现有技术起步,通过技术精化使加工精度接近10—0.1nm的极限。 英国Cranfield Precision Engineering公司近年来在纳米技术领域取得不少新进展。该公司销售工程师LesleyAsque指出:“在该领域,一切都必须极为精密。譬如说,切深控制不仅涉及到机械学,而且涉及到了电子学。”该公司为Gleason齿轮公司开发的螺旋伞齿轮加工控制系统就是一个例证。 Lesley Asque说:“Gleason公司认为,由于螺旋伞齿轮加工涉及10或12个不同坐标轴,故用传统CNC无法加工。我们为此进行了可行性研究,认为可将螺旋伞齿轮机床的控制轴数降到6个。”
Nowadays, nanotechnology (1nm = 10 ~ (-9) m) mostly starts from the prior art and researches the precision of the technology to approach the limit of 10-0.1nm. Britain Cranfield Precision Engineering Company made a lot of new progress in the field of nanotechnology in recent years. Lesley Asque, a sales engineer at the company, said: “Everything in this space must be extremely sophisticated, for example, depth-of-cut control involves not only mechanics but also electronics.” The company developed helical bevel gear for Gleason Gears The system is an example. Lesley Asque said: “Gleason believes that spiral bevel gear processing with conventional or CNC can not be processed because it involves 10 or 12 different axes, we conducted a feasibility study that the helical bevel gear machine can control the number of axes Drop to 6. ”
