Abstract
The utility model discloses a lathe tool for working Mg alloy workpieces. The cutting part of a lathe tool is made of high-speed steel or hard alloy materials, and the sum of a rake angle gamma, a back angle alpha and a wedge angle beta of the main cross section of the cutting part of the utility model is 90 DGE. The rake angle gamma of the main cross section of the cutting part is from 20 to 35 DGE, the back angle alpha is from 10 to 15 DGE, an auxiliary angle kappa of the cutting part is from 0 to 10 DGE and the tool point rounded angle radius of the cutting part is from 1.2 to 2.4 mm. The utility model successfully solves the problems that holes shrink and planes warp during the course of machining Mg alloy workpieces, mechanical machining to the Mg alloy workpieces with high accuracy is realized and the fine machining property of the Mg alloy obtains reflection.
Description
Technical field
The utility model relates to a kind of metal cutting tool, particularly a kind of lathe tool that is used for the processing magnesium alloy workpiece.
Background technology
Characteristics such as magnesium alloy materials has approaching specific strength, specific rigidity because of its low-density with aluminium alloy, and damping and amortization is good, vibration damping is good, electromagnetic wave shielding is good and more and more be subjected to the attention of countries in the world, so the Application of Magnesium scope is also more and more widely.In order to satisfy final dimension precision requirement, most of magnesium-alloy materials all must carry out machining.At present, most enterprises all directly utilize the cutter of processing Al alloy parts to come the processing magnesium alloy workpiece, but magnesium alloy workpiece is compared with the workpiece of machined steel or aluminium alloy when machining, have some special physical characteristics, low as hardness, resistance to cutting is low, thermal capacity is little, thermal coefficient of expansion is high, directly utilize the cutter of processing Al alloy parts to come the processing magnesium alloy workpiece, can realize for the product that requirement on machining accuracy is not high, but for the dimension precision requirement high product, but be difficult to meet the demands, often occurring the hole after processing shrinks, cold deformations such as warpage, the splendid machining property that magnesium alloy is had originally fails to obtain to embody, and therefore need the cutter of processing magnesium alloy workpiece be redesigned.
Summary of the invention
The purpose of this utility model provides a kind of lathe tool that is used for the processing magnesium alloy workpiece, can reach the processing request of high accuracy magnesium-alloy material with it, simultaneously the splendid machining property of magnesium alloy can be embodied.
The purpose of this utility model is achieved in that the cutting tip of lathe tool is high-speed steel or Hardmetal materials, and the anterior angle γ of its cutting tip main cross section, relief angle α, angle of wedge β sum are 90 °.The anterior angle γ of described cutting tip main cross section is 20 °～35 °, and relief angle α is 10 °～15 °; The auxiliary angle K of described cutting tip is 0 °～10 °; The blade radius of described cutting tip is 1.2～2.4mm.
Owing to adopted such scheme, the cutting tip of lathe tool adopts high-speed steel or Hardmetal materials to make, the anterior angle γ of cutting tip main cross section is 20 °～35 °, and in order to reduce the cracked possibility of cutter, the anterior angle γ of the cutting tip of tungsten carbide button's material is 20 °～30 ° and is advisable; The relief angle α of cutting tip main cross section adopts than 10 °～15 ° of the cutting bigger angles that other metal allowed, in case stop bit rubs mutually with workpiece in the cutter position of cutting edge back and causes excessive heating and sticking cutter.The auxiliary angle K of cutting tip is 0 °～10 °, can avoid cutter to tremble.The blade radius of described cutting tip is 1.2～2.4mm, and this blade radius is bigger slightly than the blade radius of other metal of cutting, so that adopt higher feed speed reaching under the condition that certain surface smoothness requires.This lathe tool has adopted above-mentioned geometric angle, has successfully solved problems such as hole contraction in the processing magnesium alloy workpiece process, plane warping, has realized the machining to the high accuracy magnesium alloy workpiece, makes the good machining property of magnesium alloy obtain embodiment.
The utility model is described in further detail below in conjunction with drawings and Examples.
Description of drawings
Work schematic diagram of the present utility model when Fig. 1 is cylindrical turning;
Fig. 2 is the angle figure of the 0-0 of Fig. 1 to the main cross section.
The specific embodiment
Referring to Fig. 1, Fig. 2, the cutting tip of the utility model lathe tool is that high-speed steel or Hardmetal materials are made, and the anterior angle γ of its cutting tip main cross section, relief angle α, angle of wedge β sum are 90 °.The anterior angle γ of described cutting tip main cross section is 20 °～35 °, and relief angle α is 10 °～15 °.This cutting tip adopts the main cross section anterior angle γ of high speed steel material to be advisable with 25 °～35 °, and perhaps this cutting tip adopts the main cross section anterior angle γ of Hardmetal materials to be advisable with 20 °～30 °.The auxiliary angle K of described cutting tip is 0 °～10 °; The blade radius of described cutting tip is 1.2～2.4mm.
The anterior angle γ of the cutting tip main cross section of present embodiment adopts 25 °, and relief angle α adopts 15 °, and angle of wedge β is 50 °; The auxiliary angle K of cutting tip is 10 °; The blade radius of cutting tip is 1.8mm.Cutting tip employing high-speed steel or Hardmetal materials all can reach the machining requirement to the high accuracy magnesium alloy workpiece, and the good machining property of magnesium alloy is fully reflected.
