Johnford SV48H VERTICAL MACHINING CENTER

Technical Description

This CNC machining center measures 126" x 102" x 118" and weighs approximately 17,600 lbs, featuring a spacious 55.1" x 23.6" table capable of supporting loads up to 3,300 lbs. It offers precise multi-axis travel with 48" on the X-axis, 28" on the Y-axis, and 24" on the Z-axis, and an adjustable spindle nose-to-table height ranging from 5.9" to 29.9". The machine is equipped with a CAT 40 spindle taper driven by a 15 HP motor capable of speeds up to 6,000 RPM. It achieves rapid traverse rates of 944 inches per minute across all axes and cutting feed rates between 0.04 and 393.7 inches per minute for versatile machining operations. Tool management is handled by a 24-position automatic tool changer supporting tools up to 15 lbs in weight, 11.8" in length, and diameters of 3.1" with adjacent tools or 4.9" without. Tool change time is optimized at 2.5 seconds per tool. The system is controlled via a Fanuc 0i-MD CNC controller, ensuring precise and reliable operation. Supporting infrastructure includes a 30 KVA power requirement, 80 PSI air pressure, and 20 CFM air flow. Additional features enhancing machining performance and maintenance include a chip conveyor, coolant system, rigid tapping capability, spindle chiller, automatic lubrication system, and a full enclosure for safety and containment, making this machine suitable for heavy-duty and high-precision manufacturing applications.
