Description
Technical Field
The utility model relates to a milling cutter processing field, concretely relates to antiseized even spiral milling cutter.
Background
A milling cutter is a rotating tool with one or more cutter teeth for milling. When in work, each cutter tooth cuts off the allowance of the workpiece in sequence and intermittently. The milling cutter is mainly used for processing planes, steps, grooves, formed surfaces, cut-off workpieces and the like on a milling machine.
The end milling cutter is the most common milling cutter in milling cutters, and has the left-handed rotation and the right-handed rotation, when milling, the left-handed milling cutter and the right-handed milling cutter can generate results with different chip removal directions in the same rotation direction, the left-handed rotation generally removes chips downwards, and the right-handed rotation generally removes chips upwards. The left-hand milling cutter is a lower chip removal milling mode, and chips on the surface of a workpiece are not cleaned. The cutting force is applied downwards, the machined workpiece cannot be lifted, and the workpiece is not easy to shift. The lower scraps can also avoid the phenomena of whitish knife edge, edge jumping of the machined part notch and the like.
Generally, when precision parts are machined and a chip removal space is arranged below the precision parts, a left-hand milling cutter is basically used and has certain advantages when the left-hand milling cutter is used for machining workpieces with special precision requirements. However, when some devices with high viscosity are milled, chips generated by milling may be stuck in the chip removal groove or even block the chip removal groove, so that the removal of the chips is inconvenient, and the subsequent processing process is affected.
The present invention is designed to solve the problems that when the existing milling cutter mills a sticky device, the chips can be adhered to the chip grooves and even lead to the blockage of the chip grooves.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that the unable fine solution of prior art is at present milling cutter when milling and having viscidity device, and the piece can the adhesion lead to the problem that the chip groove blockked up even in the chip groove.
The utility model discloses a following technical scheme realizes:
