Contour-Profiled Grinding Wheels Save Time, Increase Tool Life
IMTS 2018: Lach Diamond’s metal-bond, contour-profiled grinding wheels are designed to reduce the number of processing steps during deep grinding of a variety of materials.
Lach Diamond’s metal-bond, contour-profiled grinding wheels are designed to reduce the number of processing steps during deep grinding of a variety of materials. Resin-bond grinding wheels need several processing steps to grind components made of carbide, high-alloyed steels, ceramics and non-oxide ceramics, but metal-bond grinding wheels can do similar work in only a single step, according to the company.
The wheels enable the grinding of many profile types, both concave and convex at tight tolerances ranging to 0.005 mm. One wheel is said to provide equivalent capacity to eight regular abrasives and wheels. According to the company, the wheels increase tool life by as much as 25 times and save time by as much as 35 to 60 percent due to higher feed rates per workpiece.
No other process can do what creep-feed grinding can do. Recent tests show even more can be gained by optimizing every element of a creep-feed system.
If one must pick a manufacturing specialty, grinding carbide might not be the first choice because it’s perceived to be very difficult. RPM Carbide Die, however, has worked the material for nearly 40 years and, as specializing seems increasingly to be the order of the day, this northern Ohio shop is in a good position to thrive.
Wire EDM units that swivel a horizontally guided electrode wire in a CNC-controlled E axis give this shop the workpiece clearance and flexibility to produce complex, high-precision PCD-tipped cutting tools.
