TRIO ARM is a small cnc contouring machine with three interpolated axes expecially designed for engravings jobs, cutting and profiling countertops and even deep sinks. TRIO ARM has a working area with 1500 mm x 900 mm dimensions and a vertical run of 200 mm. The distance between the spindle and the working table is 380 mm and let the operator process stone thickness up to 200 mm. The machine can process even large slabs.

The main structures (base and arm) is made up of steel sandblasted and zinc-paint protected. Two coats of final paint is applied

MOVEMENTS OF THE MACHINE
The X, Y e Z axes move on guides and slides with 4 recirculation ball screws which are completely protected from water and dust.

The advancement of the X axis and the Y axis is via a special precision rack which is cemented and rectified and has inclined teeth and is completely protected from dust and water. The movement is by brushless motor with a system for gauging the quota via an incremental encoder.

Axis Z is on a vertical slide; the advancement is via a work screw and precision travel nut with recirculating ball screws which is completely protected from water and dust. The movement is by brushless motor with a system for gauging the quota via an incremental encoder.

THE MILLING UNIT
The milling unit works via a 5 HP electro-spindle with water running through and a rotating joint. Rotation speed of the electro-spindle from 0 to 6000 rpm. controlled by an electronic frequency inverter. Tool connection ½ gas. System for external cooling of the tool via water nozzles.
