A trio of Walter tool measurement and inspection machines representing all aspects of sophistication levels and budget will be displayed at Control 2017, from the laser scanning Helicheck 3D to the manual Heliset, as well as the Helicheck Plus.
These three machines – plus the other four machines in Walter’s tool measuring range – are available in the UK from Walter Ewag UK, a member of the United Grinding Group.
With X, Y and Z axes capacities of 270 mm by 455 mm by 325 mm, plus an A axis of 360deg, the Helicheck 3D utilises a revolutionary method of digitising to enable items to be scanned quickly and easily to create three-dimensional model data that can be saved, processed, analysed and measured.
The machine’s 3D Tool Analyser software - specifically developed for the application – can lay horizontal, vertical and freely selectable cutting planes at any position on the 3D model. These are automatically analysed and the resulting parameters made available for use.
The capability to measure all important tool features has never been quicker or simpler than with Helicheck 3D and since measurements are carried out on virtual models, the process can be performed offline.
A software 3D ‘matcher’ enables users to create a colour-coded comparison of two 3D models within the machine’s graphical user interface. After the ‘match’ of both models, the operator instantly receives an evaluation of the quality of the products and any deviations from desired values.
The four-axis Helicheck Plus has four CCD cameras for measuring tools, grinding wheels and workpieces from 0.1 mm to 200 mm diameter and up to 300 mm long, weighing 25 kgs, to a measuring resolution of 0.25 micron and a repeatability of one micron.
The Heliset is a manual machine for measuring tools and grinding wheels easily, quickly and precisely. While tools up to 350 mm diameter and 400 mm long can be measured, another major machine benefit is that it enables grinding wheels to be prepared offline while tool production continues.
