Gleason has launched a new online selector tool for its line of LeCount® expanding mandrels that greatly reduces the time and effort needed to exactly match any LeCount Mandrel to the application.
The LeCount mandrel, patented by Charles W. LeCount in 1866 and continuously improved on over the last decade by Gleason, is considered the industry’s leading expanding mandrel solution for inspection applications, as well as for prototyping tasks and small lot manufacture.
Just one expanding mandrel can cover a large number of applications. This cost-effective and high-precision solution makes LeCount expanding mandrels the first choice when it comes to clamping bore-type parts on metrology systems and prototyping work. The patented, tool-less design of the LeCount mandrel is based on the principle of parallel expanding jaws that slide smoothly to grip the inside diameter of the part. The expanding mandrel itself is then placed between centers of the metrology system or manufacturing machine. Simple handling combined with high precision clamping provides for excellent concentricity with errors of less than 2.5 µm over the entire clamping length. It is the perfect clamping system for all bore-held workpieces, whether gears, turned parts or similar components.
LeCount expanding mandrels feature bore clamping diameters from 6.5 to 177 mm and are available in different versions: with two clamping sections to cover particularly wide ranges, with only one clamping section for long parts, as compact version if distance between centers or weight is an issue, for very small diameters, or for hob inspection. In addition, G Type production mandrels feature a stronger clamping force and are protected against contamination, particularly well-suited for prototyping and small lot manufacture on lathes, turning of parts with smooth bores, hard turning, or OD and face grinding. Optionally, all mandrels can be equipped with part locators for horizontal positioning, or designed as spline mandrels for parts with splined bores.
