MAXIMUS 1.5 PROFILE PROJECTORS Ø 1500 MM HORIZONTAL PROJECTIONS

Being the most prestigious models of this exclusive brand range, this giant profile projector features the very latest developments in the field of large size optical comparators drawing on Microtecnica very long expertise dating back to 1954 when the company became the first manufacturers worldwide to produce profile projectors with screens of 1.000 mm diam. The Maximus 1.5 model is the result of the most advanced technology combined with high performance qualities and confirm Microtecnica global leadership and esteemed reputation as innovative instrumentation providers. Several thousands of endusers operating in different industrial sectors and having common requirements of high quality and reliability are working satisfactorily with Microtecnica profile projectors all over the world and represent the best guarantee for potential new customers

MANUFACTURING FEATURES
Worktable group

The projection screen of respectively 1.000 mm and 1.500 mm is located at the side of the worktable group thus allowing the operator a free access to the screen.
It is mounted on a sturdy vertical slide similar to a milling machine, with preloaded roller guides allowing high accuracy even when measuring heavy workpieces up to 150/200 kgs. Powered horizontal and vertical displacements are carried out by means of recirculating ball-screws combined with DC motors having continuous speed adjustment.

CNC 
The table displacements can be numerically controlled enabling automatic checking of workpieces. The CNC is provided with a “teach-in” facility which allows to memorize the measuring path and then automatically repeat it. A flexible and customized printout format can be easily issued in order to certify the performed testing and calculations. The measuring software installed on the PC allows a graphic configuration of the workpiece under testing.

Pivoting lamp/optical condenser holder arm
This facility, common on all horizontal type Microtecnica models, ensures easy positioning of heavy workpieces on the table area. Furthermore it enables the operator to complete finishing works on gauges, moulds, tools, dies, etc. directly on the worktable, thus making the workpiece removal unnecessary.

Turret lens holder
In replacement of the standard single lens holder, where bayonet type lenses are placed manually, Maximus 1.5 can be fitted with a revolving turret housing up to 4 lenses for a quick and easy lens changing operation.
