The F10A Boring Bar has been designed for standard and large capacity machine work. The spindle diameter is larger than that of the F9A. It has been increased to 3.25" (8.2mm) for extra heavy duty machining up to a 9" (230mm) bore size. Large sleeve cuts can be taken at high spindle rpm's, and in many blocks, one pass sleeve cuts are possible, which increases productivity.
The massive one piece meehanite, stress relieved, precision machined base of the F10A model allows the fixturing of large diesel blocks such as Cummins 855, Detroit 12V71, Mercedes 44V12 and odd jobs such as gear cases and connecting rods.
The F10A machine can also handle small jobs down to 1.5" (38mm) bore diameter with optional cutterheads.
Floor-to-floor bore a V8 block in 15 minutes. Bore through a 6" (152.4mm) bore 4" (101.6mm) in diameter in 35 seconds, .250 sleeve cuts are not a problem. Tooling is available from 1.500 to 9 inches in diameter. Straight through and blind hole boring tools are available. Precision ball screws on the feed give the ultimate feed control.
Features:
- Speed
All three models of FA Series machines have the same high performance AC servo motor, delivering up to 1200 RPM. Independent feed control allows you to change the feed rate from .001” (.025mm) to .012” (.3mm) per revolution.
- Accuracy
The FA Series uses a precision ground ball screw to control feed rate and cutter position. This allows the machines to repeat cutter position accuracy to .0002” (.005mm). The FA Series have digital programmable cycles. Boring depth can be programmed to .0001” (.0025mm).
- Strength
Rottler has increased the size of the F8A spindle to ensure the best possible bore geometry at high spindle speeds. The Rottler proven spindle and bearing design gives you a rigid machine capable of making heavy sleeve cuts for a life time. The F7A spindle has been reduced to allow the machining of compact engines, motorcycles, marine blocks, etc.
- Flexibility
The F Series machines have variable feed rates that allow you to maximize the performance of the machine. Increase spindle feed rates for simple oversize bores. Decrease feed rates for sleeve cuts or counter bores. The F8 machines can bore from 1.5” (38mm) to 9” (230mm) in diameter, with optional cutterheads. The F7 machines can bore from 1.5” (38mm) to 5” (127mm). Special carbide tools are available for counterboring, chamfer cutting, offset boring, and O-ringing.
- Automation
The A models have programmable boring cycles and automatic centering cycles. Both models will store up to 100 different boring programs. Each program stores boring depth, spindle speeds, and feed rate. Automated cycles reduce costly errors while freeing operators to perform other tasks.
- Reliability
The F Series machines use a high-speed, cogged belt drive system. This, and the use of two independent motors to run the spindle speed and feed, entirely eliminates the gear box. With fewer moving parts, and a superior design, the F Series becomes a much more reliable boring bar than other designs of equipment
- Cost Savings
The high speed Rottler F Series machine can bore a block in half the time that other models of boring machines require. New insert technology is producing long lasting, inexpensive inserts which are capable of handling these high speeds and feed rates, with the same cost per insert as previous styles. Inserts do not require sharpening and the low cost of these tools makes them the ultimate choice for boring cylinders.
