Rigid 5-Axis VMC
February 1, 2014
Sharp's SVX-500 vertical machining center (VMC) allows true 5-sided and 5-axis simultaneous machining. "Unlike the 3-axis that requires a separate set-up for cutting different sides of a part, the 5-axis machine requires the part to be set only once and rotated into a series of positions to machine each side without the need to reset the part," said a company spokesperson.
All major castings of the SVX-500 are analyzed using the Finite Element Method (FEM) to locate areas of stress and strain, multiple loading conditions from thermal, gravity, centrifugal and enforced displacement. Rib locations are properly defined to maintain rigidity throughout the entire machine. The 5-axis is constructed using the box-in-box design to help provide accuracy and rigidity under different cutting conditions. The workpiece is fixed along the X- and Y-axis to allow large, heavy parts to be machined. The spindle head moves on a high-precision roller guideway along the X- and Y-axis on top of the box structure. "Such arrangement maintains total machine balance and eliminates overhang due to a moving table," said the spokesperson. "The integrated trunnion table is part of the fixed table that offers ample undercut capability. It accommodates large work volume and delivers more torque at a lower RPM than the swivel head machine. The SVX-500 also facilitates the transition from 3-axis to 5-axis machining practice due to the similarity in approach to parts.
"The Sharp SVX-500 utilizes a linear scale and rotary encoder as standard to achieve high accuracy, along with geometric accuracy by hand scraping. The rigid roller guide has a low center of gravity to stand the pressure from any direction and provide a long life."
The SVX-500 is equipped with a high-precision spindle that delivers 30 HP, 15,000 RPM and is mounted on ceramic bearings that deliver 87 ft-lbs. (118 Nm) of torque. The VMC features travels of 23"/31.8"/19.7" (XYZ), total body weight of 27,500 lbs. and a capacity of 770 lbs. (350 kg). The SVX-500X is equipped with the new Fanuc 31-B5 CNC control or a Siemens control. Standard accessories include a pull out coolant tank, flood coolant, fluorescent work light and auto-lubrication system.
