LK计量学通过新的超准确便携式测量武器扩展自由范围

静态坐标测量机(CMM)制造商LK计量学has added five new ultra-accuracy models to its FREEDOM range of portable measuring arms.

每种模型都有6轴和7轴变化,使LK的投资组合中的武器总数达到34。

The new models fall under two new categories within the FREEDOM range, FREEDOM ULTIMATE and FREEDOM ULTIMATE SCAN, and are designed to offer increased precision across a wide range of applications, such as quality control, on-machine verification, reverse engineering, and 3D modeling.

Recent metrology advancements

First established in 1963, LK’s history in metrology dates back to the birth of CMM technology. After several years as a division ofNikon Metrology, LK was relaunched as an independent CMM manufacturer with offices located in the UK, North America, and Europe. The firm is continuing to advance metrology in 3D printing alongside several other companies in the field.

其中之一是总结的测量系统制造商Creaform去年推出了最新的3D扫描仪,旨在制造和计量专业人员,称为the MetraSCAN BLACK。CMM由计量级蓝色激光技术支持,可以在制造过程的任何阶段,从产品设计到维护和维修再到逆向工程。

公司的其他3D测量产品包括Go!SCAN SPARK and HandySCAN BLACKportable 3D scanners, and Creaform’s technology has alsopowered two new handheld scanners来自3D扫描仪制造商peel 3D

在其他地方,3D扫描和图像提供商FARO Technologies推出了其最新,最准确的迄今为止3D便携式CMM,the FARO Gage。The portable arm is well-suited to daily high-accuracy tasks performed by small and medium-sized businesses, combining lightweight benefits with lab-precision.

Meanwhile, global engineering firmRenishaw最近宣布其计量部门在H1 2021期间已获得2.356亿英镑的收入,尽管它经历了减少对CMM产品的需求,特别是在航空领域。

增强的测量精度

LK的新臂模型将使用ISO认证的校准球体和验证杆运输,并提供2.5至4.5米的测量量。

The new models are equipped with enhanced measuring accuracy over existing arms in the range, providing an eight percent accuracy improvement over the next most precise product, the SELECT, and are up to 43 percent more precise than the range’s entry-level CLASSIC arm models.

尽管整个自由范围具有ISO认证的触觉探测精度,但新扫描模型中的额外灵活性提供了无限运动,可以使用尼康计量模型制造商H120激光扫描仪扫描。可以使用各种探针套件,佩蒂利,安装环,三脚架和滚动架来定制每个臂,还可以提供配备笔记本电脑臂的手推车,以方便客户。

Carbon fiber stability

The new FREEDOM arm models are manufactured with a carbon fiber tubular construction in order to provide greater stability under challenging operational conditions. When users are attempting to access awkward areas of a component, a proprietary counterbalance makes manual movements light, thereby making the measuring arm easier to use in these types of situations.

手臂还配备了可选的Wi-Fi连接性和电池电量,以使它们完全便携,并能够进行无线测量。由于最大的自由模型的重量小于11公斤,因此设置和重新定位变得更快,更容易,当不使用时,可以将手臂简单地放开并锁定在适当的位置。

提高生产率

One factor that sets the new FREEDOM arm models apart from their predecessors is the integration of absolute, rather than incremental, rotary encoders that feed back the angular position of each joint to the control software. This removes the need for timely encoder referencing before use and means the arm can be used immediately when started up, thereby raising productivity.

由于嵌入了高度可重复的热量交换连接,可以快速交换臂的探针,而不会中断测量过程以进行重新校准。LK还在模型的探针手腕上添加了一个带有快速访问菜单的LCD显示屏,该菜单在整个测量过程中为用户提供了对重要信息的立即访问。

一系列的第三方软件可以检查supplied by LK to accompany its FREEDOM arms. One of those available isInnovMetric’sPolyWorks Inspector software, which can seamlessly swap programs between portable and static CMM platforms. Also offered isMetrostaff的ArcoCAD metrology software and Nikon Metrology’s Focus Inspection program for data analysis. Additionally, the CMM Manager inspection package from OxSoft can be used for touch-probing.
