Heavy-Duty VMC features 48 x 28 x 25 in. X/Y/Z travels.
Press Release Summary:
Equipped with 20 hp spindle with 2-speed gearbox head that provides full power at 305 rpm, SV-48H is 50-taper VMC built for heavy cutting applications. It performs stable cutting with rapids of 944 ipm on fully supported, 3,300 lb capacity table that has zero overhang. While Class 7 steel bearings permit standard spindle speeds to 6,000 rpm, optional hybrid ceramic bearings enable speeds to 10,000 rpm. Other features include 4 square box ways on Y axis, Fanuc OiM-C control, and ATC.
Original Press Release:
SV-48H Vertical Machining Center by Johnford: Heavy-Duty VMC Boasts Generous Y Axis Capacity
o Generous capacity (48" x 28" x 25" XYZ travels)
o 20 HP spindle with 2-speed gearbox head provides full power at 305 RPM
o Highly rigid thanks to four square box ways on the Y axis
o Stable cutting on the large, fully supported table with zero overhang
o Highly productive machine delivers fast rapids of 944 IPM
o Sports standard features others offer as options
Lorain, Ohio, January 24, 2008 - Shops wanting speed, rigidity, and plenty of capacity in a competitively priced 50 taper vertical machining center should seriously consider the SV-48H VMC by Johnford. Absolute Machine Tools, Inc. offers this VMC, which is specifically engineered for heavy cutting applications. According to Absolute President Steve Ortner, "The SV-48H's capacity, performance, and total cost set it apart from its competition. No one else offers 28" travels in Y and so many standard options at such a price. The SV-48H easily handles heavy cuts because of a two-speed gearbox head that provides plenty of torque at low RPM. In addition to being a powerful machine, the SV-48H is also fast, delivering 944 IPM rapids."
The SV-48H's heavy Meehanite FC-30 castings provide the strength and vibration damping necessary for exceptional surface finishes and long cutting tool life. The machine also sports features not found on competitive machines at any price, including four square Y axis box ways and a large fully supported table with zero overhang. The large diameter, pretensioned ballscrews and the large diameter rigid spindle are ideal for heavy cutting. Mating Turcite-B coated surfaces are hand scraped for exceptional fit and precision.
The SV-48 has a 3.35" (85 mm) spindle shaft employing five bearings for unparalleled stiffness and cutting stability. Class 7 steel bearings permit standard spindle speeds up to 6,000 RPM. For applications requiring high torque at low RPM, a standard two-speed geared head gives full power at only 305 RPM. The spindle delivers up to 10,000 RPM with the addition of optional hybrid ceramic bearings. A 15,000 RPM Weiss integral spindle with HSK-100A tooling is also available for ultra high speed machining.
Beefy Class 3 ballscrews, measuring 1.57" (40 mm) in diameter, feature a double-nut preloaded design. Ballscrews are also pretensioned to eliminate thermal growth and promote high accuracy and high speed positioning. High torque servo motors directly couple to the ballscrews for additional accuracy.
A Fanuc OiM-C control is standard with Manual Guide Oi conversational programming, Custom Macro B, coordinate system rotation, and front-panel PCMCIA card slot for up to 2 GB storage. For more demanding 3D applications, an optional Fanuc 18iM-B with AI NANO HPCC is available.
Standard features include a 24 tool high speed, arm-type ATC that provides 3.0 second tool changes, dual rear-discharge screw-type chip conveyors, flood coolant with programmable air blast, spindle oil chiller, and rigid tapping capability.
