In the process of cutting titanium, the precautions are

In the process of cutting titanium, the precautions are:
(1) Due to the small elastic modulus of Custom Titanium Parts alloy, the deformation of the workpiece clamped in the processing of large deformation and stress, will reduce the machining accuracy of the workpiece; workpiece clamping force installation should not be too large, increase aid support when necessary.
(2) If using liquid hydrogen cutting, the cutting process will decompose at high temperatures to release hydrogen embrittlement caused by absorption of titanium; it may cause high temperature titanium stress corrosion cracking.
(3) the use of cutting fluid chlorides are also likely to break down or volatile toxic gases, the use of security measures should be taken, otherwise it should not be used; after cutting should be timely and chlorine-free cleaning agent thoroughly cleaned parts, remove residual chlorine thereof.
(4) prohibits the use of lead or zinc-based alloy production workers, fixture and titanium contact, copper, tin, cadmium and its alloys are also prohibited.
All workers, fixtures or other devices must be in contact with the titanium clean; titanium parts cleaned off, to prevent contamination of grease or fingerprints, or after the salt may cause stress corrosion.
Under normal circumstances when machining titanium alloys, no ignition hazard only when micro-cutting, small chips have cut ignition combustion phenomenon. To avoid fires, in addition to a large number of pouring coolant should prevent chips piled on the machine tool to be replaced immediately with a blunt or reduce cutting speed, feed rate increased to increase the chip thickness. If once the fire should be used talc, limestone titanium metal, dry sand, fire fighting equipment were extinguished, prohibited the use of carbon tetrachloride, carbon dioxide fire extinguisher, nor watering, because water can accelerate the burning, and even lead to a hydrogen explosion.
