Hi-Net High Speed machining centers

Hi-Net high speed machining centers by Johnford are specifically designed for the high speed, net shape machining of complex surfaces. These machines feature the latest machine designs, high speed spindle technology, and the fastest CNC controls available. We start with FEA proven rock solid machine construction and add world-class high speed spindles and Fanuc CNC controls to produce machines that compete at the highest level at an affordable cost. In mold machining applications, these machines produce precisely accurate molds that require little or no hand work with the fastest cycle times. Other applications include dies and aerospace.

Hi-Net machining centers are available in a variety of sizes and configurations to meet any need. The SV-33, SV-41 and SV-48 are box way C-frame machines that have been specifically designed for high speed machining. These machines can handle small to medium size workpiece requirements and are available with 18,000 or 24,000 RPM HSK-63A spindles. The DMC series machines are double column (bridge mill) designs made to handle medium to large size workpieces and heavy table loads. They employ box ways in Y and Z and roller type linear ways in X. They are available in your choice of 15,000 RPM HSK-100A and 24,000 or 18,000 RPM HSK-63A spindles. See Video

The all new Super Hi-Net machining centers are our latest generation of high speed finishing. Common features of the Super Hi-Net machine are no counterbalance in Z, implementation of Schneeberger roller linear ways on all three axes, and HSK 63A spindles only. The machine designs have been modified for rigidity and accuracy at ultra high speeds. Currently, there are four models available. The SHV-1000 is a ram head type of vertical machine that features a light weight ram for the Z axis for increased acceleration. The DMC-909, 912, and 915 are double column machines with improved cutting speeds over the standard Hi-Net double columns.

All Hi-Net machining centers are equipped exclusively with Weiss spindles manufactured in Germany. These spindles provide the speed, power, rigidity and reliability necessary to meet today's high speed machining requirements. For heavy cutting and fine finishing all in one spindle, the 15,000 RPM HSK-100A spindle is the answer. It produces 56HP and 300 ft./lbs. of torque at only 1000 RPM, providing the best of both worlds. For medium roughing and high speed finishing, the 18,000 RPM or 24,000 RPM spindles are the best choice. The 18,000 RPM spindle produces 29HP and 68ft./lbs. of torque at 2300 RPM while the 24,000 RPM spindle produces 31HP and 53ft./lbs. of torque at 3000 RPM. The HSK tooling system is used exclusively to provide the balance, rigidity, and accuracy necessary to produce the best results.

The Fanuc 18iM-B control with AI NANO HPCC is the fastest control available and is the only control offered on the Hi-Net machines. The 18iM-B uses NANO technology for the ultimate in precision and speed. The control is mated via fiber optics to the new Fanuc Alpha i servo system features high response and high torque servo motors equipped with 1,000,000 pulse encoders. The AI NANO HPCC (high precision contour control) delivers 150,000 block/min. processing with a 600 block look ahead to navigate radical vector changes without violating the surface being machined. The control is standard with an ethernet connection and 640MB built-in ATA card for large program storage.

If you require state-of-the-art high speed machining technology without breaking the bank, please send us your inquiry. We would be happy to prove our product side-by-side with any competitor using test cuts or benchmark parts. Everyone talks high speed, let us prove it.
