Description

Technical Field

[0001] This utility model relates to the field of casting processing technology, specifically to a precision casting processing equipment. Background Technology

[0002] Castings are objects with a certain shape, size and properties obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after smelting molten metal, cooling and then processing them through grinding and other subsequent processing methods. Drilling is one of the common processing methods in casting production.

[0003] In the existing technology, the casting drilling equipment can only perform drilling operations on a single casting, and can only drill one hole at a time. For some regular castings (such as round plate castings), multiple symmetrical holes may need to be drilled on their surface, which will lead to low drilling efficiency. Utility Model Content
