船舶和潜艇制造

为了满足船舶和潜艇应用的苛刻要求，制造出来的部件需要有极高的质量、耐用性、精度和可靠性。

鱼雷发射管对准

一种易于操作的方法，用于检查鱼雷发射管的直线度和直径，精度在 0.05 mm（0.002 英寸）以内。

这种方法无需使用长而笨重的塞规，并且在进行检查时无需将船舶停靠在干船坞区。记录的数据被用来制作发射管的内部轮廓图，以便与模板进行比较，模板规定了鱼雷顺利通过发射管所需的轮廓。

潜望镜对准

潜望镜是潜水艇的眼睛。轴承错位的潜望镜需要电机提供更多的动力来克服阻力。由此产生的功率激增会产生更大的噪音，导致很容易被敌方的搜索艇发现。

潜望镜被安装在位于潜艇鳍部和耐压壳结构中的一系列轴承中。这些轴承的对准是至关重要的，任何不对准都会导致潜望镜变形，并可能损坏轴承本身。

船舶/发动机对准

造船厂和轮机工程师都很清楚，验证船舶推进装置是否正确对准是一个很大的挑战。具体挑战是调整船舶发动机相对于螺旋桨轴系和艉轴管的位置。该方法的原理是设置一个与发动机轴线同轴的测微准直望远镜。

方向舵轴承对准

望远镜形成的直线视线可以用来对准船舵中的轴承。

‘P’ 支架

在与物体碰撞后，必须检查发动机/齿轮箱、螺旋桨轴轴承和“P”支架轴承是否仍然对准。一个镜靶被同时安装在可调节的支架上和齿轮箱的主轴上。装有灯箱的望远镜被设置在 90 方向上，与镜靶成一条直线。

Refurbishment of Diesel Engines using Boring Bar

A common use of boring bar alignment is refurbishment of large diesel engines such as ship and locomotive engines. The problem involves worn bearings needing to be realigned before being rebushed and the bush recut using a boring bar.

The solution, a reference line of sight is made by sighting through the front and rear bearing. Bushes (shells) are then placed in each of the bearings, and all aligned in anticipation of the boring bar. Normally a hollow boring bar is used, and wire targets are placed inside the bar at regular intervals to monitor its straightness as it moves into and along the engine bearings. Wire targets are often used because they do not have any glass and therefore do not refract the light and cause optical errors. If glass is used light will be refracted through each target and error produced.

Without moving the telescope, the telescope is refocused on the boring bar at the various cutting positions to ensure the boring bar is travelling in a straight line and that any sag is removed. A camera system with dedicated software makes the adjustment of the boring bar easier since the image can be viewed by the operator as adjustments are made.

In some rare cases, a solid boring bar is used. Here a mirror target can be put onto the front nose of the boring bar and the telescope used in auto-reflection or autocollimation mode. In these modes a mirror target enables the telescope to be put in line and square to the boring bar.
