Five-Axis Spark Grinder Sharpens Diamond Cutting Tools
The universal five-axis Dia-2200-Mini from Lach Diamond is designed for the automatic sharpening of diamond tools and saw blades.
The universal five-axis Dia-2200-Mini CNC spark grinding machine from Lach Diamond is designed for the automatic sharpening of diamond tools and saw blades with diameters as wide as 530 mm. The machine is capable of sharpening new or servicing old diamond end mills and jointing cutters both with and without axis angles. It is also effective on diamond scoring saws and saw blades of all tooth types. The grinder offers profiling programs (both contour-controlled programs with copper electrodes and in-feed programs with graphite electrodes).
A program for multiple production is available, capable of automatically sharpening multiple diamond tools or axis angle jointing cutters. The company has also developed an axis angle program that allows for extreme axis angles of more than 45 degrees during production and service.
The system was designed for grinding tools for machining fiber composites such as glass fibers (GFP), carbon fiber reinforced plastic (CFRP) and basalt fabrics in the aerospace, agricultural machinery and automotive industries.
Real-time-responding CNC brings new possibilities to difficult machining applications.
Two enabling technologies -- superabrasive wheels and high precision servo control -- come together to provide a contour grinding process that resembles an OD turning operation. For many medium volume OD grinding applications, this method may be a means to consolidate several manufacturing steps into a single setup.
It sounds like a contradiction in terms-between centers and centerless grinding on one machine. But for some categories of workpieces, it's a viable production process that can yield machining time reductions of 45 percent over separate grinding operations.
