Manual Measuring System for Tool Grinding
United Grinding introduces the Heliset Plus, a manual measuring system from Walter that is said to contribute to the reduction of complex tool machining time by as much as 30 percent.
United Grinding introduces the Heliset Plus, a manual measuring system from Walter that is said to contribute to the reduction of complex tool machining time by as much as 30 percent. Once integrated into tool production processes, the system concurrently performs measurement operations previously done in separate tool preparation areas or within the machine that produces the tool.
The system works seamlessly with Walter machines that process complex cutting tools using both grinding and electrical discharge erosion operations.
For ease of use, the new measuring system features an intuitive user interface and touchscreen operation. A live front-light image of the tool being processed speeds positioning of measuring points and provides a clear representation of cutting edges already measured, which enables shops to operate the system immediately and without the need for programming. Resulting XML data output from the measuring system instantaneously transfers to Walter Window Mode software within the grinding and eroding machines or to CNC measuring machines to save tool processing time.
The system measures tools as large as 350 mm in diameter and 400 mm long. It includes a workstation, a manual axis adjustment and an ISO 50 spindle, as well as a back-light camera with 45× magnification and a front light. The company is developing the machine’s capacity to also measure grinding wheels.
Functional gear testing, also known as total radial composite deviation, is a method of looking at the total effect of gear errors. This test method simulates the conditions under which a set of gears is likely to operate as a result of the gears meshing together.
A laser scanning system helps this shop capture the free-form surfaces on a hand-sculpted original. The resulting digitized models are the basis for CAM applications such as programming a CNC machining center.
The irregularity of a machined surface is the result of the machining process, including the choice of tool; feed and speed of the tool; machine geometry; and environmental conditions. This irregularity consists of high and low spots machined into a surface by the tool bit or a grinding wheel.
