We have developed an economical duplex milling machine which is very affordable and is a no frills attached machine. A brief description of this machine is given below:

Features and Specs:

• Base made of square section, with adequate ribbing to provide more than sufficient rigidity with light weight. .
• Atop the base, a slide is mounted in the middle.
• The slide is made of LM guides and leadscrew with a stroke of 700 mm to cut 330 mm of width.
• The slide is run by AC induction motor connected to worm reduction gear box which inturn will be coupled to ballscrew.
• The AC induction motor is coupled to a VFD to obtain stepless feed from 100mm/min to 2800 mm/min for rapid return.
• On the slide a fixture is mounted with manual toggle clamps.
• Two milling heads are mounted on either side of the slide.
• The milling heads are run by a 1.5 HP AC induction motor coupled to the spindle through timer belt and pulley.
• The milling head is provided with ISO-40 spindle taper capable of holding Ø63mm cutter.
• The milling heads are provided with all cast iron cross axis manual depth of cut setting, of 50 mm.
• The machine will be run through a relay based auto-cycle sequence.
• The sliding surfaces with be lubricated by a centralized lubrication with timer.

Sequence of operation:

• Load the component and clamp using manual toggle clamps.
• Press auto-cycle button.
• The component gets feed against the cutters, after stroke ends, the component returns in rapid and stops.
• Unload the component
