Triag tripoxyMINERAL Tombstone
The thermal expansion is similar to that of steel, but thermal transfer is considerably slower than that of metals. There is a further advantage in that the relatively soft material of the mineral tombstone gives way if there is a collision with the machine spindle. Only the tombstone needs to be replaced, or it may even be possible to continue the operation with other tombstones. If, in contract, the spindle is damaged, the costs resulting from the machine failure can be very high.
More than twenty standard molds are currently available. The cross-tombstone, which provides optimal spindle accessibility for three-sided machining, should be particularly mentioned here. The side faces are ground, and have hardened M12/12F7 positioning sockets.
