ultra investment material:
Use Aluminium oxide Al

(30 µm – 250 µm)
For very fine parts (inlays) careful blasting with polishing
beads is sufficient.
Procedure for finishing titanium
Follow the finishing instructions in the correct sequence.
This enables you to achieve an excellent polish on the
titanium with very little effort and expense.
Preparation of surfaces for ceramic applications:
– use tungsten carbide burs only
– blast carefully with Al

(125 µm – 250 µm) and
23 bars of pressure.
Important: After polishing, the workpiece must be allowed
to passivate in the atmosphere for 10 minutes before
cleaning with steam jet or ultrasonic cleaner.
In addition to the component numbers, observe the order
numbers for spare parts on page C 9.
