Technical Parameters for RFQ
- Machine spindle: BT30, BT40, BT50, CAT, HSK or another interface.
- Cutter model and mounting: FMB/FMA, pilot diameter and bolt pattern.
- Required runout: state gauge length and maximum TIR, for example ≤0.02 mm at the gauge line.
- Cutting load: cutter diameter, insert count, material, depth of cut and coolant method.
- Quantity and balancing: include G6.3/G2.5 balance speed when required.
Applications
Select a short, rigid arbor for heavy roughing and a precision-ground interface for finishing. Verify gauge length, pull-stud specification and cutter bolt pattern before ordering.
Frequently Asked Questions
How do I select BT40 versus BT50?
Match the machine spindle. BT50 is preferred for higher torque and heavier cutters; BT40 suits compact machining centers and moderate loads.
Can you supply a custom arbor?
Yes. Send spindle type, cutter drawing, gauge length, pilot and bolt pattern. BOFA can quote a matched arbor and balancing option.
What information speeds up an RFQ?
Include machine model, interface, cutter diameter, mounting standard, runout target, quantity and delivery region. Request an arbor quote.
