6. Machining process of titanium machining parts

Titanium spons → 3 maal VAR smelten → Smeden → Slijpoppervlak → Radiaal smeden door SPX -25 → Rechttrekken → snijlengte → Gloeien → Ruwe bewerking → Ultrasoon inspecteren → Fijne bewerking → CNC-bewerking → Boorgat → Tikken (indien nodig) → Polijsten → Inspecteren → Verpakken → Leveren

7.Bewerkingsvereisten voor titaniumlegeringen

1. Machining characteristics of titanium and titanium alloy

a & nbsp;small deformation coefficient: when the deformation coefficient is less than or close to 1, the distance of sliding friction on the front cutting face increases greatly, which accelerates the tool wear.

b. High chip temperature: under the same cutting conditions, the cutting temperature can be more than twice as high as when cutting 45 steel.

c. & nbsp;large cutting force per unit area: easy to cause tool breakage, increase tool wear and affect the accuracy of parts.

d. Ernstig fenomeen bij koude verharding: verminder de vermoeiingssterkte van onderdelen en verhoog de slijtage van het gereedschap.

e. Slijtage van het gereedschap: onder de hoge snijtemperatuur en grote snijkracht per oppervlakte-eenheid is het gereedschap gemakkelijk zelfklevende slijtage te veroorzaken.

2 Tool selection

a. & nbsp;Cutting titanium and titanium alloys should be based on reducing the cutting temperature and reducing the bonding. Select a tool material with good red hardness, high bending strength, good thermal conductivity and poor affinity with titanium alloys.

b. & nbsp;It is often suitable to use YG hard tools. The commonly used hard alloy tool materials are: YG8, YG6X, YG6A, 813, 643, YS2T, YD15, etc.

c. Diamant- en kubisch boornitride zijn ook verkrijgbaar als gereedschap.

3 Requirements for processing equipment

a. & nbsp;Set up a special processing site and determine the special machine tools for processing titanium and titanium alloys.

b. & nbsp;Laying rubber sheet or wooden floor in the work area to avoid scratching the titanium surface.

c. & nbsp;All tools, fixtures, machine tools or other devices in contact with titanium and titanium alloys must be clean.

d. & nbsp;After cleaning the titanium alloy parts, it is necessary to prevent grease or fingerprint contamination, otherwise the salt (sodium chloride) stress corrosion may be caused in the future.

e. & nbsp; Het gebruik van lood, koper, tin, cadmium en hun legeringen is verboden en gereedschappen en armaturen gemaakt van op zink - gebaseerde legeringen komen in contact met titaniumlegeringen.

4 Requirements for cutting

a. & nbsp;Due to the small elastic modulus of titanium and titanium alloys, the clamping deformation and stress deformation of the workpiece during processing will be large, which will reduce the machining accuracy of the workpiece. The clamping force of the workpiece installation should not be too large, and auxiliary support can be increased if necessary.

b. & nbsp; De snijvloeistof is geselecteerd uit chloride - gratis snijvloeistoffen.

c. & nbsp;During cutting, a large amount of cutting fluid should be poured to sufficiently cool the titanium and titanium alloy during processing.

d. & nbsp;During processing, prevent chips from accumulating on the machine

e. & nbsp;Replace the tool immediately after using blunt, or reduce the cutting speed, increase the feed to increase the chip thickness

f. & nbsp;If fire occurs during processing, fire extinguishing equipment such as talcum powder, limestone powder, dry sand should be used to extinguish the fire. Carbon tetrachloride, carbon dioxide fire extinguishers are strictly prohibited and watering is not allowed.
