Equipped With

ACRA MODEL LCV-2414 MINI MILL MACHINING CENTER WITH FAGOR 8055I CONTROLLER

• 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. 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 Scraping the base casting where the column mounts is shown.
• 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 pretension 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 pretension and anchored at both ends will have much greater play and backlash which can lead to problems with chatter and 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. 42 gallon capacity Coolant tank with standard chip bin is shown
• 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 or chip basket.
• Large Side Doors
Both sides of the machine enclosure have large removable doors. Long workpiece can be loaded through the sides. The door openings are large enough to allow full “Y” axis travel with long workpiece extending through the sides
• Air Reservoir Tank
An air reservoir tank with alarm is used to stabilize the incoming air pressure and volume.
• 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.
