Page 9: Recipients Of The Manual
Serial number: See cover INSTRUCTION MANUAL Date: 05/04/2018 C6 milling centre Page 9 of 65 The machine must be protected against exposure to strong radiation, both ionising and non- ionising and from contaminants such as gas, corrosive gas, powders, acids, oils, chemical products, detergents and any other product not specifically mentioned in this Manual. -
Page 10: Purpose
Although the milling machine can use files generated by any CAM software – provided they are in a standard ISO format - the Client is requested to use only CAM software with a post- processor SPECIFICALLY APPROVED BY DENTAL MACHINE, to prevent any uncontrollable behaviour by the machine. -
Page 11: Conserving The Manual
Milling – even occasionally and using standard ISO formats - according to files generated by a CAM (and/or post-processor) not approved by Dental Machine shall automatically make void any warranty provided by the Manufacturer, unless the user proves beyond any reasonable doubt that the failure is not due to the CAM and/or post-processor. -

It simply represents an invitation to the user of the A5 milling machine to take maximum care, given that documentation on this subject is poor and conflicting. - Page 59 Serial number: See cover INSTRUCTION MANUAL Date: 05/04/2018 C6 milling centre Page 59 of 65 linear reduction of approx. 25% (i.e., to obtain 100 mm when finished, the raw piece must be approx. 125 mm). During cooling, the reverse transformation should occur, with the volume increased again. This does not occur because the passage from the tetragonal structure to the monoclinic one (which would lead to the formation of cracks until breaking) is blocked by special additives (e.g.

- Page 62 Note that wet milling the zirconia requires an additional drying cycle prior to the actual sintering process. For this reason almost all users of the Dental Machine G5 milling machine prefer to dry mill this material. This may generate a risk of exposure to zirconium oxide powder by both the machine operator and anybody else that may be in the room where the machine is installed.
