 Traditionally, the machining of grooving lands in hydraulic valve bodies is a very time-consuming operation.
The patented UM GROOVING LAND TOOL™ is a profile cutter which is used for machining all grooving lands in one shot.
In some cases, half of the grooving lands are machined from one side and the rest from the other side of the spool bore. Sometimes, the tool can also be used in connection with cavity holes.
The tool often replaces a cutter with inserts only machining one grooving land at a time. Usually, each spool bore has 7-15 grooving lands, and this means that the UM GROOVING LAND TOOL™ reduces machining time considerably.
