Jig Mills Offer Accuracy, Rigidity for Moldmaking Applications

Mitsui Seiki USA, Inc. (Franklin Lakes, NJ) announces a new series of large, highly accurate CNC Jig Mills 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 10 microns. Further, table squareness to the Z-axis is also better than 10 microns. “The accuracy of these machines is really unparalleled,” said Thomas Dolan, the vice president of the company. “Our design offers significantly tighter control in boring operations than conventional moving/sliding crossrail configurations.”

Working size range is for the J1620 is (X) 2,100 mm x (Y) 1,600 mm x (Z) 500 mm. Table size is 2,400 mm x 1,600 mm with a load capacity of 4,000 kg. With the J1620X version, all of the specifications are the same except the X-axis (which is 2,500 mm) and the table (which is 2,200 mm x 1,500 mm). A variety of CNC U-axis boring heads are available on both models. The machines feature a 10,000 rpm 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 tools to 180 tools and more. Likewise, 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 popular Fanuc 30i-B control combines user-friendliness and exceptional levels of accuracy, reliability, and efficiency. Machine enclosure and guarding options on the Jig Mills meet current environmental, health, and safety standards.
