The model ISO 5.5F spindle was originally designed to meet the demanding requirements of the ultra-precision single point diamond turning industry. The application of the ISO 5.5F has grown to include conventional flycutting, raster flycutting, free-form surface generation, HDD servo track writing, DVD mastering, and metrology in vacuum environments. The Spindle’s central stiffness and extremely low error motion while being driven with a powerful brushless-DC motor can not be matched by any other spindle manufacturer in the world. See a few example parts machined with the ISO 5.5F spindle. Specifications Inlet Pressure: 6.9 bar Ultimate Axial Load Capacity: 1110 N Ultimate Radial Load Capacity: 890 N Axial Stiffness (at spindle nose): 210 N/µm Radial Stiffness (at spindle nose): 90 N/µm Axial Error Motion: < 25 nm Radial Error Motion: < 25 nm Maximum Speed: 10,000 rpm Motor Torque: 7.5 N·m continuous to 3,200 rpm (B12-25 motor) View/Download drawing in PDF format Drive Amplifier: MCS AX-2000 Encoder #1: Renco #R35i, 1024 line count with hall effect devices Encoder #2: Renishaw RESM, 9000 line count with one read head (mounting provision for second read head) Spindle to amplifier cables: 4.0 meters long Spindle Weight: 340 N Options The ISO 5.5E motorization option. B13-25 brushless dc motor 4.0 N·m continuous torque to 9,200 rpm with MCS AX-2000 drive apmlifier and a 10,000 rpm max. speed. B12-25 vs. B13-25 brushless dc motor comparison. The B12-25 motor provides more continuous torque at slower speeds (less that 4,000 rpm) and lower radial synchronous error motion (the B12-25 typically has less than 1.0 nm of motor pole print thru) vs. the B13-25 motor (typically 2.0 — 8.0 nm of motor pole print thru). Both motors are of a 12 pole design. Second Renishaw read head. Spindle to amplifier (power and communications) cables 10.0 meters long. |
