The import tool post system that I installed some time ago on my lathe is shown in photo 1. This is a typical starter pack comprising the tool post and five different tool holders. The four way tool post originally supplied with the Chester UK Craftsman lathe is shown at the back right, for size comparison. The starter pack of five different tool holders comprises, from the front left, a boring bar holder, a Vee tool holder, a knurling tool holder, a standard or square tool holder and finally a wedge type parting blade holder. The QCTP system described here came from Arc Euro Trade (ref 1) and is their size 200 and very clearly marked 'China'. Many of the other importers offer similar items in different sizes to match the lathe size (centre height). You may find these described as AXA, BXA, CXA, CA, DA etc., all names that come, originally, from the Aloris Tool Technology Company, USA. (ref 2). This company claims to have been the inventor of the QCTP in 1946.

机译：我之前在车床上安装的导入刀架系统如图1所示。这是一个典型的入门包，包括刀架和五个不同的刀架。最初与Chester UK Craftsman车床一起提供的四向刀架显示在右后方，以进行尺寸比较。五个不同刀架的入门套件从左前开始包括镗杆刀架，Vee工具刀架，压花工具刀架，标准或方形工具刀架，最后是楔形分割刀片刀架。这里描述的QCTP系统来自Arc Euro Trade（参考资料1），大小为200，标记为“中国”。其他许多进口商也提供不同尺寸的类似产品，以匹配车床尺寸（中心高度）。您可能会发现这些名称分别是AXA，BXA，CXA，CA，DA等，所有名称最初都来自美国Aloris Tool Technology Company。 （参考2）。该公司声称自己是1946年QCTP的发明者。
