Hardened and Ground Box Ways All guide ways are induction hardened then precision ground Meehanite Cast Iron Meehanite cast iron is used on all structural components. Finite Element Analysis (FEA) is used to optimize the structure for rigidity. No Table Overhang A wide saddle fully supports the worktable throughout the travel. Base Casting The base is a rigid one piece casting with four “Y” axis ways Heavy internal ribs are used to achieve maximum stiffness. Precision Hand Scraping All mating surfaces are precision hand scraped to increase the flatness and improve geometric accuracy (straightness and squareness) of the whole assembly Turcite B Turcite B is bonded to all sliding surfaces. Oil grooves are machined and then it’s hand scraped to produce an excellent bearing surface. Note that even the mounting surfaces for the ball screw nut are hand scraped. This assures that it is square to the ball screw and guide ways Ball Screws Each axis is driven by a high precision double-nut ball screw that is centered between the guide ways. The ball screws are pre-tensioned and anchored at both ends with angular contact thrust bearings. Double-anchored and double-nut ball screws greatly increase machining rigidity and allows for much heavier cuts. Ball screws using single nuts or ones that are not pre-tensioned and anchored at both ends will have much greater play and backlash which can lead to problems with chatter and accuracy. Axis Drives To reduce backlash, all axes are connected directly to Fanuc A.C. digital servo drive motors without the use of gears or belts Fanuc Alpha Series Spindle Motor Horsepower is rated in both continuous operation and maximum for 30 minutes. Torque is also rated for 30 minutes of operation (see Standard Machine Specifications above). Many other builders only give a “Max” power ratings with no time length given. This is the estimated maximum power for only 1 minute or less. Typically these motors continuous power and torque rating are less than 1/2 of their stated maximum. SV-4328SX (12,000 rpm spindle) : Spindle Chiller Refrigerated oil is circulated around the spindle to draw heat from it. This helps to control thermal expansion which can effect accuracy Separate Roll Out Coolant Tank A large separate roll out coolant tank is used to prevent heat in the coolant from transferring to the machine base casting. 132 gallon capacity Flood Coolant High pressure flood coolant with adjustable nozzles is standard Large Side Doors Both sides of the machine enclosure have large removable doors. Long work pieces can be loaded through the sides. The door openings are large enough to allow full “Y” axis travel with long work pieces extending through the sides Electrical Cabinet Heat Exchanger For increased reliability, a heat exchanger is used to cool the components inside the electrical cabinet. Automatic Lubrication System Automatic lubrication with alarm is provided to all ways and ball screws. Lubrication oil is delivered by metered piston distributors to precisely control the volume of oil. Fanuc 0i-MD CNC Control The new Fanuc 0i-MD CNC control comes with a 10.4”color LCD, a new user interface, more memory, 20 block high speed look ahead function, a faster processor and NANO interpolation. RS232 port and Ethernet are also included Remote Jog Handle A hand held “Manual Pulse Generator” lets each axis move in increments of x1, x10 or x100 for easy fixture or part alignment. 300 psi Coolant Through The Spindle Preparation The spindle is prepared for coolant through with a pressure up to 20 bar ( 290 psi).. External hardware including pumps and filters are not included (see optional accessories). CTS greatly improves tool life when cutting hard metals. SV-4328 SX Productivity Package* Chip Conveyor + Chip Coolant Flush + Coolant Gun + 4 Spare M Codes $9,450.00 A general purpose non-perforated hinge belt type chip conveyor with chip cart Chip Coolant Flush System To keep chips from building up inside the machine enclosure, coolant is pumped from the sides (inside the enclosure) to flush chips down to the chip conveyor. Coolant Gun A convenient hand held coolant nozzle is provided for washing the work piece and/or the inside of the machine enclosure. 4 Spare M Codes 4 spare (user definable) M codes are included. These can be used for auxiliary equipment such as high pressure CTS that require communication with the CNC control.
