Cutting method of huge pure titanium billet square billet

Abstract

The invention relates to a cutting method of a huge pure titanium billet square billet, and belongs to the technical field of production application. The huge pure titanium billet square billet produced by an electron beam cold hearth melting furnace is horizontally placed on a sawing machine, a to-be-cut position is selected, a feed speed and a sawing speed are set, and certain axial pressure is applied to a cutting piece, so that cutting can be performed in a specific position conveniently. The cutting method has the advantages as follows: the cutting accuracy is high, the cutting period is short, the operation is simple, the service life of a saw blade can be prolonged greatly, and better economic benefits can be obtained.

Description

Technical field

[0001] The invention belongs to the technical field of production and application, and particularly provides a convenient cutting method for giant pure titanium workpieces. Background technique

[0002] Titanium and its alloys have excellent mechanical properties, physical properties and biological properties (high specific strength, low density, corrosion resistance, low modulus, good biocompatibility, etc.), so they are used in aerospace and biomedical devices, especially man-made Implant materials have been increasingly widely used and are a very competitive material.

[0003] In the ingot produced by the electron beam cooling bed furnace, due to the influence of the volatiles of the crystal pulling crucible and the adhesion of impurities on the surface of the ingot head, the impurity elements on the head of the titanium caster produced by fusion casting exceed the standard, which has an adverse effect on the later process. For this reason, before the s...

Examples

Embodiment 1

[0009] Place the giant pure titanium billet (cross-sectional area: 1380mm*210mm) produced by the electron beam cooling bed furnace on the sawing machine horizontally, select the position to be cut, set the feed speed (15m / min), and the cutting efficiency (10cm) 2 / min), apply axial pressure (about 10MPa) to the cut small parts, the maximum sawing deviation is 3.0mm, and the average number of cuts is about 10 times. Under the same conditions, the average number of times without applying axial pressure is about 7 times.

Embodiment 2

[0011] Place the giant pure titanium billet (cross-sectional area: 1380mm*210mm) produced by the electron beam cooling bed furnace on the sawing machine horizontally, select the position to be cut, set the feed speed (18m / min), and the sawing efficiency (13cm) 2 / min), apply axial pressure (about 10MPa) to the cut small parts, the maximum sawing deviation is 3.2mm, and the average number of cuts is about 8 times. Under the same conditions, the average number of times without applying axial pressure is about 6 times.

Embodiment 3

[0013] Place the giant pure titanium billet (cross-sectional area: 1380mm*210mm) produced by the electron beam cooling bed furnace on the sawing machine horizontally, select the position to be cut, set the feed speed (20m / min), and the sawing efficiency (15cm) 2 / min), apply axial pressure (about 10MPa) to the cut small parts, the maximum sawing deviation is 3.5mm, and the average number of cuts is about 7 times. Under the same conditions, the average number of times without applying axial pressure is about 5 times.
