Date Stamps - DME Multidater MD

Mat: Stainless steel

Hardness: 50-55 HRC

Мах. Т: 150°C

Outer Ring: 12months, months 1 through 12

Inner Ring: 6 years + arrow (arrow points to month

Center Insert: arrow (points to year & adjusts position of both arrows)

Double indexable: Both arrows independently ‘click” into position

Change positions easily with only a screwdriver using arrow in inner insert

Turn clockwise to change “year” arrow (6 years)

Turn counterclockwise to change “month” arrow (12 months)

All inserts remain flush when rotated

Dual-Ring insert may be interchanged for the 20mm, 16mm, 10mm, 8mm to 6mm diameter indexable and Front-removable inserts

The MDxxOD version is needed to trace days. The inner ring counts the ten and the outer ring counts the units.

The two multidaters together indicate the complete date. For example 31 on the MDxxOD version and 10 2019 on the other indicates 31st of October 2019

*Specify year. Example: MD062019

MD080D	MD0820*	6	8	5,3	2,5	10	5

Installation and Machining

Press-fit installation required
Maintain a close tolerance press fit. Too loose a fit could allow the insert to move out of position, while too tight a press fit might prevent the inner insert and inner ring from rotating when required
Accurately measure the ® D for each part and machine hole to provide about 0.005mm (.0002″) press fit

Structure and Usage

Method of changing over the indication
Changing the year indication. When the center part is turned clockwise (A), only the inside arrow rotates, enables the year to be changed.
Changing the month indication. Turning the center part counterclockwise (B) causes both the inside arrow and the second ring to turn simultaneously, enabling the month to be changed?
