Super Hi-Net SHV-1000 Vertical Machining Center by Johnford for Moldmakers

"Mold shops wanting speed, rigidity, and precision in a competitively priced vertical machining center should seriously consider the Super Hi-Net SHV-1000 VMC by Johnford," said Steve Ortner, president. Absolute Machine Tools, Inc. offers the Super VMC, which is specifically engineered for high speed mold machining. The machine features include the Schneeberger roller type linear ways on all axes, large diameter pre-tensioned ballscrews, and a state-of-the-art integral spindle for fine finishes.

The SHV-1000's heavy Meehanite castings ensure the VMC has the strength and vibration dampening required to produce excellent surface finishes. Large diameter, pretensioned ballscrews and powerful servo motors ensure accurate positioning.

The machine's Y-axis features four ways for support and accuracy. Its Z-axis is a ram type head with no counterbalance for increased acceleration. Rapid rates are 944"/min in all axes.

Weiss integral spindles, made in Germany, 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 2,400 RPM is also available.

The standard Fanuc 18iM-B with all new alpha I series servo motors and AI NANO HPCC is standard for high speed, accurate machining. The control provides 600 blocks look ahead/150,000 blocks/min processing. A 640MB ATA built-in card provides mass program storage and Ethernet connectivity. The control also allows for NURBS Interpolation of complex mold programs.

Other standard features include a heavy duty 24-tool arm type ATC mounted to the left side of the machine for easy maintenance, a chip removal system consisting of twin screw type rear discharge conveyors, a high volume coolant system, and a full machine enclosure to contain chips and coolant.
