概要
Feedback

当社非磁性のSUS303ステンレススチール製Ø38 mm(Ø1.5インチ)ポストには、大型で強度のある立体構造を組み立てる際に必要とされる基本的な構成要素部品が豊富に揃っています。このページに詳細を記したポスト製品には、多数のアクセサリを固定できます。当社のポスト、ポストスペーサ、ポストベースはステンレススチール製で、端の接続部分は強度と剛性を得るための大径リリーフカットが施されています。

Pシリーズのポストとポストスペーサは積み重ね可能で、組み合わせて使用することによって高さを調整できます。Pシリーズのベースを使うと、光学テーブルにポストを自由な位置に取り付けることが可能です。ポストの端にあるM6タップ穴によってしっかりとポスト同士を締め付け固定できるので、長くて剛性のあるポストを作ることができます。また、タップ穴にネジ-位置決めピン変換アダプタ(下記参照)を使用すると、ポストを固定する前に、取り付け面のタップ穴の上に自由に回転させて位置合わせすることができます。

What is the tolerance on the OD of this post? Thanks, Dan

Thank you for contacting Thorlabs. The outer diameter tolerance for the P200/M is 1.486±0.001 in. I have reached out to you directly regarding this. Additional data and specifications can be requested by reaching out to us at techsupport@thorlabs.com.

The solidworks files for all the metric posts will not load, file error. I do not have this problem with any other product I tried from the site

Response from Jeremy at Thorlabs: The SolidWorks files were created using SolidWorks 2016 and it will not open on older version of SolidWorks. To get around that, you can download and use the STEP files instead.

Response from Javier at Thorlabs to Vorvick: Thank you for following up with us. We will develop a solution in order to prevent deflection of the fork under the load of the screw. Please contact us at techsupport@thorlabs.com with your contact information so that we can keep you updated.

A response to Adam for Vorvick. Your are correct that the fork is bowing, but this really has nothing to do with the 3-point contact as you mentioned, rather it is caused by simple deflection of the fork under the load of the screw. In this case the fork bowed so much that the mid portion made contact with the mounting surface (optical table) and thus made it not usable. I suspect that this fork is made of aluminum and that combined with small clearance will casue this problem.

A response from Adam at Thorlabs to Vorvick: I would like to get more information about the clamping fork is being used. From the description, it almost sounds like you are experiencing a bowing issue which should not happen due to the three point contact that the design permits. I will email you directly to get more information.

fork is too flexible - touches table where the screw is - defeats the purpose - having to redo my setup without it.

For all post types -- it would be extremely useful if the posts were marked (e.g. laser etching) with length, diameter, and tapped hole size/pitch on the side (and ends if possible). Spacers could be marked on their faces. A 2 inch post looks an awful lot like a 50 mm post, and a 1/4-20 tap looks a lot like an M6. Labels would ensure that the correct part is pulled out of the drawer the first time...
