The boring bar hatch clamping screws with spherical ends are required to attach the unit comprised of REV BROACHING TOOL and eccentric bushing perfectly to the CNC lathe. Also, whenever it is necessary to correct any keyway alignment error, these screws hold the tool in the work position, making it much easier to adjust the eccentric bushing.
6 categories of them are kept in stock, from the smallest size called BU-1, which is equivalent to M6x15, to the largest one called BU-6, equivalent to M16x30. The hardness of the spring varies in relation to screw size.
Before making a purchase it is necessary to check exactly which type of screw is suitable for the boring bar hatch provided with the machine tool.
