Abstract
The invention discloses a solid carbide numerical control end mill for processing titanium alloy, which improves the cutting blade angle of the solid carbide numerical control end mill and is used for cutting and processing titanium alloy material. The solid carbide numerical control end mill for processing titanium alloy comprises a mill handle and a cutting blade, wherein the anterior angle of the side blade of the cutting blade is 7-9 degrees, the relief angle of the side blade of the cutting blade is 14 degrees, and the centripetal angle of the end of the cutting blade is 2-3 degrees. The invention has the advantages: because the anterior angle of the side blade of the cutting blade is widened to be 7-9 degrees, the relief angle of the side blade of the cutting blade is widened to 14 degrees and the centripetal angle of the end of the cutting blade is widened to 2-3 degrees, the cutting edge is sharp, the cutting resistance is reduced, and the abrasion to the cutting blade is reduced; thus, the cutting performance of the numerical control solid carbide end mill for processing titanium alloy is improved, the cutting and processing removal ratio is correspondingly improved to 19.2cm<3>/min, and the once cutting and processing time for the cutter is 52 minutes.
Description
Technical field:
The invention is the improvement to the solid carbide numerical control end mill cutting edge profile, is used for the Milling Process of titanium alloy material.
Background technology:
Titanium alloy is a kind of difficult to machine material, its main cause is because poor thermal conductivity, elastic modelling quantity are little, therefore, the cutting ability of material is poor, wearing and tearing to cutter are bigger, especially the bounce-back of surface to be machined material is bigger, make that the cutter wear of the tool flank is very fast, and existing solid carbide numerical control end mill for processing titanium alloy spiral cutting sword side edge anterior angle and relief angle are less, anterior angle numerical value is 0 °～5 °, and relief angle numerical value is 10 °～12 °, makes cutting edge not sharp, cutting resistance is big, but also has aggravated the wearing and tearing of cutter; The entad angle of spiral cutting sword end is less, and numerical value is 1 °～2 °.Finally, caused existing solid carbide numerical control end mill for processing titanium alloy cutting ability poor, the machining clearance is low, generally at 8～10cm
3/ min, the disposable machining time is short, is generally 35～45 minutes.Therefore, be difficult to satisfy the high-quality and efficient processing request of titanium alloy component.
Summary of the invention:
The purpose of the invention provides a kind of solid carbide numerical control end mill for processing titanium alloy that improves cutting ability and improve working (machining) efficiency; The purpose of the invention is to realize by following technical scheme: solid carbide numerical control end mill for processing titanium alloy, comprise milling cutter shank and cutting edge, it is characterized in that cutting edge side edge anterior angle makes 7 °～9 °, cutting edge side edge relief angle is made 14 °, and the entad angle of cutting edge end is made 2 °～3 °.
The advantage of the invention:, make 7 °～9 ° because cutting edge side edge anterior angle is strengthened; Cutting edge side edge relief angle is strengthened, make 14 °; The entad angle of cutting edge end is strengthened, made 2 °～3 °, make cutting edge become sharp, cutting resistance has reduced, and wearing and tearing reduce to cutting edge; Therefore improved the cutting ability of solid carbide numerical control end mill for processing titanium alloy, improved the machining clearance accordingly and reached 19.2cm
3/ min, the disposable machining of cutter was for up to 52 minutes.
Description of drawings:
Fig. 1 is the solid carbide numerical control end mill for processing titanium alloy structural representation;
Fig. 2 is the A-A tangent plane schematic diagram among Fig. 1.
Among the figure: 1, the entad angle 4 of cutting edge 2, milling cutter shank 3, end, the side edge anterior angle 5 on the cutting edge, the side edge relief angle on the cutting edge
The specific embodiment:
Solid carbide numerical control end mill for processing titanium alloy comprises milling cutter shank and cutting edge, it is characterized in that cutting edge side edge anterior angle makes 7 °～9 °, and cutting edge side edge relief angle is made 14 °, and the entad angle of cutting edge end is made 2 °～3 °.
Advantage:, make 7 °～9 ° because cutting edge side edge anterior angle is strengthened; Cutting edge side edge relief angle is strengthened, make 14 °; The entad angle of cutting edge end is strengthened, made 2 °～3 °, make cutting edge become sharp, cutting resistance has reduced, and wearing and tearing reduce to cutting edge; Therefore improved the cutting ability of solid carbide numerical control end mill for processing titanium alloy, improved the machining clearance accordingly and reached 19.2cm
3/ min, the disposable machining of cutter was for up to 52 minutes.
