Franklin Lakes, New Jersey – A new series of large, highly accurate CNC jig mills are suitable for mold base production, mold plates, precision hot runners, progressive and transfer dies, and other jig boring and milling applications. The fixed crossrail, massive ram design of the new Jig Mill J1620 and J1620X machines, provides a straightness accuracy in X and Y axes better than 10µm according to the company. Further, table squareness to the Z-axis is also better than 10µm. The design offers tighter control in boring operations than conventional moving/sliding crossrail configurations.
Working size range is for the J1620 is X – 2,100mm x Y – 1,600mm x Z – 500mm. Table size is 2,400mm x 1,600mm with a load capacity of 4,000kg. With the J1620X version, all the specifications are the same except X-axis is 2,500mm and the table is 2,200mm x 1,500mm. A variety of CNC U-axis boring heads are available on both models. The machines feature a 10,000rpm built-in integral spindle with a 50 taper interface. The spindle technology controls growth and provides thermal stability. Customers can choose from a variety of toolchanger units with capacities from 10 to 180 tools and more. A variety of coolant and chip evacuation systems can be chosen to match the customer’s needs. Ultra-precise probing is also an option as an aid to workpiece setup and in-machine inspection functions. The control is a Fanuc 30i-B.
