Johnford's Super Hi-Net SHV-1000 VMC is designed and built for high-speed mold machining. The machine sports Schneeberger rollertype linear ways on all axes, large diameter pre-tensioned ballscrews, and a state-of-the-art integral spindle.
The SHV-1000's heavy Meehanite casting ensures the VMC has the strength and vibration dampening required to produce excellent surface finishes and to significantly extend cutting tool life. Furthermore, large diameter, pretensioned ballscrews and powerful servomotors ensure accurate positioning.
The machine's Y-axis features four ways for exceptional support and accuracy. Its Z-axis is a ram-type head with no counterbalance for increased acceleration and smooth operation. Rapid traverse rates are 944 in/min in all axes.
German made, Weiss integral spindles, are standard equipment. The machine's standard 24,000 rpm HSK-63A spindle delivers 31-hp and 53 ft/lb of torque for medium roughing and fine finishing. For more cutting torque, an 18,000 rpm HSK- 63A spindle with 85 ft/lb of torque at 2,400rpm is also available.
The standard Fanuc 18iM-B with all new alpha I series servmotors and AI NANO HPCC is standard for high-speed, high-accuracy machining. The control provides 600 blocks look ahead/150,000 blocks/min processing.
Other standard features include a heavyduty 24-tool arm type ATC mounted to the left side of the machine for easy maintenance, a chip removal system consisting of twin screwtype, rear-discharge conveyors, a high volume coolant system, and a full machine enclosure to contain chips and coolant.
