Embodiment 1
[0041] The high-precision dressing tool for the end face of a superhard grinding disc in this embodiment is used for dressing the end face of a vitrified bonded diamond grinding disc, and includes a rough repair tool, a fine repair tool, an ultra-finish repair tool and a matching abrasive liquid, and the supporting abrasive liquid includes a rough repair matching abrasive liquid , Finishing matching grinding fluid and ultra-finishing matching grinding fluid.
[0042] The rough repair tool is a resin bonded silicon carbide oil stone, and the particle size of the silicon carbide abrasive is 60#. The grinding fluid for rough repair is 80# grinding fluid A, which is composed of the following components in mass fraction: 80# boron carbide 45%, 80# graphite 15%, auxiliary dispersant 40%.
[0043] The finishing tools are resin-bonded silicon carbide stones, and the particle size of the silicon carbide abrasive is 200#. The matching grinding fluid for finishing is 240# grinding fluid...
Embodiment 2
[0046] The high-precision dressing tool for the end face of a superhard grinding disc in this embodiment is used for dressing the end face of a CBN grinding disc. The difference from that introduced in Example 1 is that the rough repairing tool is a 60# resin bonded white corundum oilstone, and the finishing tool is 200# resin bonded white corundum oil stone.
[0047] In other embodiments of the high-precision dressing tool for superhard grinding disc end faces of the present invention, the formula of the grinding liquid can be adjusted floatingly according to the formula range defined in the present invention, and the effect basically equivalent to that of the embodiments can be obtained.
[0048] 2. Specific embodiments of the method for high-precision dressing of the end face of the superhard grinding disc of the present invention
[0049] In the following examples, the structural schematic diagrams of the dressing wheels involved in rough repair, fine repair and super fine...
Embodiment 3
[0051] The high-precision dressing method of the superhard grinding disc end face of the present embodiment uses the dressing tool of Embodiment 1 to dress a vitrified bond diamond grinding disc with a diameter of 350 mm, an abrasive layer of 75 mm, and a particle size of 120#, specifically comprising the following steps:
[0052] 1) Coarse grinding
[0053] Install a circular grinding wheel composed of 60# resin bonded silicon carbide oil stones on the spindle of the vertical axis round table grinder, and use an altimeter to test the consistency of the height of each block (the height from the end face of the oil stone to the turntable) to make them consistent. Keep the resistance within 0.03mm. If there is an out-of-tolerance, use a medium-soft and hard green silicon carbide grinding wheel with a particle size of 100# for dressing, and trim to the height of each block (the height between the end face of the oil stone block and the turntable) dimensional tolerance Within 0.03...
