DESIGN AND CONSTRUCTION
The B1250L utilizes a state-of-the-art 45 degree slant bed cast base. The flat cast iron guide ways are hardened, ground and hand scraped to assure stability and accuracy. The casting is completely manufactured at the factory.
The 45 degree slant bed provides optimum chip flow for chip removal. The entire base is engineered to eliminate unwanted machine vibration. This thoroughly tested and proven machine design delivers rigidity, accuracy, and performance.
MAIN SPINDLE
The B1250L incorporates a wide-rage 53 horsepower Fanuc built-in spindle drive motor inside the turret disc. This built in motor is thermally stabilized with a cooling unit.
The motor has an electronic type C axis. Milling, drilling, tapping and cam profiling can be performed with the interpolation for the X, Z, C, and axes.
The spindle operates from 0 to 3,000 RPM. The wide range, constant output spindle motor provides powerful cutting throughout the spindle speed range. Additionally, the spindle features a 2-speed electronic “gearbox” to provide high speed cutting at top spindle RPM, while high torque is available at lower spindle speeds for heavy duty chucking.
TURRET
The B1250L horizontal axis turret is made at the factory. This 16 station bi-directional turret can accept 16 power driven tools. The driven tools engage directly, thanks to the built-in (thermally stabilized) spindle motor inside the turret disc. The turret index speed is a fast 0.3 seconds. The ability of the turret to “index on the fly” further reduces idle time.
Bi-directional turret indexing allows the turret to automatically take the shortest path to the next selected cutting tool station. The design and speed of the high-capacity turret yields reduced cycle times and lower part cost.
REVOLVING TOOL ATTACHMENT
Cross-end drilling, milling and tapping operations can be performed using power driven tools. This capability eliminates the need to perform secondary operations on a mill, thus reducing handling times and increasing productivity.
The tools are driven by a 23.5 horsepower Fanuc AC spindle motor. The motor provides 41 foot pounds of torque. Both the main and sub spindles are equipped with C axis and a disc brake which ensures accurate spindle positioning, allowing heavy cuts to be performed. The C axis control can be turned on without stopping the spindle or reducing cycle times. Both C axes positioning is accomplished with rotary Heidenhien scales.
AXIS DRIVES
The X, Z, and B axes are driven by precision ball screws and pre-loaded ball screw nuts, center mounted between the ways for optimum drive conditions. Automatic lubrication on all ways provides smoother operation and reduced maintenance expense. All drives are protected by covers and chip guards to prevent damage from coolant and chips. The drive motors are all AC Fanuc closed-loop servo drives.
TOOL PROBE
The electronic probe makes for fast and easy setting of tools, while avoiding the danger of operator error. The operator simply pushes a button to touch off the tools after each set up or insert change. The system automatically sends all data relevant to tool position to the CNC unit for storage.
RIGID TAPPING & POLYGONAL TURNING-STANDARD
Rigid tapping is fast, quick, easy yields precise threads, and does not need tap-holders with adjusted stroke. It is controlled through an M-function, which synchronizes rotation with slide feed and is available on main, sub spindles.
OPTIONAL: PROGRAMMABLE PARTS CATCHER AND CONVEYOR
The parts catcher is programmable for continuous bar work operation. After machining, the part drops into a parts catcher bucket. The parts catcher then deposits the part onto a parts conveyor, which transports the part into a parts pan. It can be set to work on either main or sub spindle.
HIGH PRESSURE COOLANT SYSTEM
The high pressure coolant is fed through the turret for the station in use to tip off the cutting tool. The high pressure coolant pump is start/stop programmable and capable of providing 60 gpm. This system provides maximum chip clearing
CHIP CONVEYOR
The chip conveyor provides automatic chip disposal. The chip conveyor is located below the work area and chips are channeled out of the machine for easy discharge into a chip cart.
On and off times are controlled through the P.C. timers to save coolant and reduce waste.
AIR CONDITIONED CABINETS
The electronic cabinet is kept at a constant temperature by a sophisticated air conditioning system. This system decreases maintenance downtime and cost. Using environmentally safe refrigerant, it also lengthens the life of the machine’s control and PC boards.
FANUC EASY Plus CONTROL with CUSTOM OPERATOR PANEL
The machine utilizes a Eurotech Elite EASY Plus control with a 32-bit hi-speed Pentium microprocessor. Part program cycle time is reduced to obtain a higher level of productivity.
Eurotech Elite’s 2D & 3D graphic parts cutting display allows programming accuracy to be checked prior to actual machining by displaying the programmed tool path in graphic form on the 15” color LCD screen.
Eurotech Elite’s work coordinate system sets the tool indexing position, simplifying programming and tool set-up and reducing machining time. The turret can be programmed to be indexed anywhere along the slide axes; either in front or along side of the work piece. Cutting tool approach distance is shortened and chip—to-chip time is kept to a minimum.
Program transfer is available via standard USB, Ethernet, Memory Card, and RS232.
Macro “B” is standard on all Eurotech’s machines to simplify programming families of parts. This function’s capabilities include parts counting, tool management, clock functions, and much more.
The servo tuning page and spindle tuning/monitoring access make optimizing your programs much easier than conventional controls.
