IKEGAI ANC-56 CNC Twin-Spindle Dual-Turret Heavy-Duty Lathe – Technical Evaluation (Year 2000 / Installed 2014)
1. Technical Evaluation Overview
The IKEGAI ANC-56 is a heavy-duty CNC center-drive lathe configured with twin spindles and dual turrets, intended for machining very long, large-diameter workpieces. Based strictly on the provided information, the machine features a maximum swing over bed of approximately 56″ and an 11″ spindle bore, supporting large hollow-shaft work. Maximum spindle speed is 400 rpm in two ranges, driven by a 50 HP main motor (a 60 HP rating is also mentioned in one description—this discrepancy should be verified).
The machine is equipped with FANUC 18 CNC controls, a chip conveyor, coolant system, and extensive workholding and support equipment. The distance between centers is reported as approximately 475″ (with a maximum part length noted up to 490″), reflecting a ~12-meter class capacity. Axis travels are stated as Right side 240″ and Left side 140″, with a distance between chuck faces of 63″.
Tooling and accessories include dual turrets with 18-position tooling, an additional programmable OD tool changer (mounted at turret position 8, holding ~12 tools), three 18″ steady rests, deep-hole boring bar holders (5″) with quick-change heads, multiple large chucks (28″ 4-jaw with 11″ through-hole; 21″ 3-jaw with 8″ hole), and a programmable right-side tailstock (6 MT). The machine is wired and under power.
2. What to Check Before Buying
Given the machine size, complexity, and mixed data sources, inspection should prioritize:
Structure, ways, and alignment
Straightness and wear of bed ways over the full ~12 m working length; verify taper control with test bars.
Alignment between headstocks/spindles and both turrets across long travels.
Spindles and drives
Confirmation of actual motor power (50 vs 60 HP) and torque delivery at low rpm.
Bearing condition and runout of both spindles; verify 11″ bore condition and sealing.
Turrets, tool changing, and rigidity
Indexing accuracy and clamping force of both turrets.
Operation of the auxiliary programmable OD tool changer (mounted on turret position 8): repeatability, tool presence logic, and integration with CNC.
Long-part support
Condition, capacity, and alignment of the (3) 18″ steady rests across positions.
Tailstock operation (programmable/manual as supplied), quill condition, and MT interface integrity.
Axes, controls, and safety
Backlash and following error on long axes (Right 240″ / Left 140″).
FANUC 18 options, backups, alarms, and synchronization logic.
Chip conveyor, coolant delivery along the full length, and guarding/interlocks.
3. Typical Industrial Applications
Based strictly on the stated capacities and configuration, the ANC-56 is technically suitable for:
Heavy turning of very long shafts, pipes, and hollow components requiring large bores and steady support.
Oil & gas, power transmission, marine, and heavy industrial components where low spindle speed/high torque is required.
Process consolidation using dual turrets for rough/finish operations on long parts.
Material grades, achievable tolerances, and cycle times are application-dependent and require test cuts.
4. Common Risks in Used Machines
Typical risks for large, long-bed CNC lathes include:
Way wear and alignment drift over long distances, causing taper or chatter.
Spindle bearing wear at low-speed/high-load duty cycles.
Complexity risk from auxiliary tool changers and long-axis control if documentation is incomplete.
Electrical/drive obsolescence depending on FANUC 18 hardware condition and spares.
5. Maintenance and Service Considerations
With no consolidated service history provided, considerations are general:
Regular geometry checks (laser/ball-bar where feasible) and lubrication audits.
Periodic spindle oil/grease analysis and steady-rest pad inspection.
Backup of CNC parameters, PMC, ladder, and tool-changer logic.
Any refurbishment planning should follow on-site inspection and test machining rather than assumptions.
Final Note:
The IKEGAI ANC-56 is a rare, large-capacity, center-drive CNC lathe purpose-built for long, heavy work. While the supplied information defines an exceptional envelope and tooling package, verification of motor rating, swing by side, axis travels, and control options is essential. A complete technical evaluation requires dimensional checks, spindle/load testing, and control review under power.
