Problems solved by technology

When using different cutting edges for processing, the existing internally cooled helical end mills can only cool the end edge and side edge at the same time. When some cutting edges do not participate in cutting, the cooling of this part of the cutting edge will cause Waste of cutting fluid and cooling pressure

Abstract

The invention discloses an internal-cooling spiral end mill. The end mill comprises a mill body, a cutting edge and an inner-cooling adjusting end cover, wherein the cutting edge comprises an end edgeand a spiral side edge, the mill body is provided with an end edge cooling channel and a side edge cooling channel, a sink table is arranged at the rear end of the mill body, the end cover can be clamped in the sink table, the bottom board of the sink table is provided with a central circular concave surface, an end edge circular concave surface, a transition circular concave surface and a side edge circular concave surface, wherein the central circular concave surface communicates with the end edge cooling channel, the side edge circular concave surface communicates with the side edge cooling channel, the end edge circular concave surface, the transition circular concave surface and the side edge circular concave surface are located in the circumferential direction of the central circular concave surface, both the end edge circular concave surface and the transition circular concave surface communicate with the central circular concave surface, the side edge circular concave surfacecommunicates with the transition circular concave surface, a plug and a through hole are formed in the end cover, the plug is matched with the central circular concave surface, when the end cover rotates, the through hole can communicate with the end edge circular concave surface or the transition circular concave surface, and a communication gap is formed between the plug and the central circularconcave surface. The end mill has the advantages that an end edge and a side blade can be separately cooled.

Description

technical field [0001] The invention relates to a metal cutting tool, in particular to an inner cooling helical end mill. Background technique [0002] The metal cutting process will generate a lot of cutting heat, and the cutting tool with internal cooling structure can take away a lot of cutting heat through the coolant, protect the tool and the machined surface, and prolong the tool life. The helical end mill is a multifunctional and efficient machining tool that can use the end edge for face milling, or the side edge for side milling, or both the end edge and the side edge for shoulder milling. When using different cutting edges for processing, the existing internally cooled helical end mills can only cool the end edge and side edge at the same time. When part of the cutting edge does not participate in cutting, the cooling of this part of the cutting edge will cause Waste of cutting fluid and cooling pressure. Contents of the invention [0003] The technical problem...
