Key Features

Meehanite cast iron 30-degree slant bed structure eliminates torsional deflection and ensures efficient chip evacuation via internal flumes.
High-precision cartridge-type spindle assembly supported by P4-grade angular contact ball bearings, delivering radial runout under 0.003 mm.
Servo-driven 12-station bi-directional turret featuring hydraulic coupling indexing for rigid tool locking and 0.2-second tool-to-tool change time.
Direct-mount absolute encoders on X and Z axes eliminate homing sequences and maintain positioning memory during power interruptions.
Integrated centralized lubrication system with pressure monitoring interlocks delivers metered grease to guideways and ballscrews.

Machining Capabilities

Max. Swing Over Bed	620 mm
Max. Turning Diameter	450 mm
Max. Turning Length	1000 mm / 1500 mm / 2000 mm options
Spindle Bore	82 mm (bar capacity up to 75 mm)
Surface Finish Capability	Ra 0.4 um in hardened alloy steel (42CrMo)
Tolerances	IT6 dimensional accuracy maintained across 500 consecutive cycles

Machine Configuration

CNC Controller

Industrial numerical control system (Fanuc / Siemens compatible architecture)

Spindle Motor

15 kW / 18.5 kW AC digital servo motor

Guideways

Heavy-duty roller linear guideways (35 mm width on X-axis, 45 mm on Z-axis)

Ballscrews

C3-grade ground ballscrews (40 mm diameter) with preloaded double nuts

Tailstock:

Hydraulic quill actuation with Morse Taper No. 5 center

Application

Oil & Gas: Threading API drill collars, couplings, and valve bodies from alloy steel forgings.

Automotive: Machining transmission shafts, constant velocity joint components, and forged gear blanks.

Aerospace: Turning structural titanium fasteners and high-temp nickel-alloy landing gear pins.

General Engineering: Producing hydraulic cylinders, pump shafts, and industrial roller bearings.

How to Choose

01/

Match Component Envelope. Select bed length based on maximum workpiece length between centers. Ensure swing over carriage clears fixture diameters.

02/

Evaluate Spindle Torque & Power. Choose 15 kW for general aluminum and carbon steel turning; upgrade to 18.5 kW or higher if executing continuous roughing cuts on cast iron or high-nickel alloys.

03/

Select Tooling Turret. Specify 12-station servo turret for standard turning; add live tooling capability if axial/radial drilling and milling operations must occur in a single chucking.

04/

Chip Management Interface. Integrate hinge-type or scraper-type chip conveyors based on material type (long stringy chips vs. short brittle chips).

Manufacturing & Quality Control

Bed Casting Aging: Meehanite castings undergo thermal stress relief annealing followed by natural seasoning for 90 days before precision milling.

Guideway Grinding: Guideway surfaces are induction hardened to HRC 52-55 and CNC surface ground to ensure straightness within 0.01 mm per 1000 mm.

Laser Interferometer Calibration: Positioning accuracy and repeatability are tested and certified on all axes using laser calibration equipment per ISO 230-2 standards.

Thermal Stability Test: Completed machines run a 72-hour continuous dry-cycle test at maximum RPM to monitor thermal growth and bearing temperature stabilization.

Inspection Protocol: Every unit ships with a complete CMM inspection report, ballbar circularity test chart, and test-cut sample piece.

Optional Configuration

C-Axis and Driven Tools (live tooling for milling/drilling)
Hydraulic Programmable Tailstock
Automatic Tool Setter
Parts Catcher and Workpiece Unloading Arm
High-Pressure Coolant System (70 bar) through-tool
Mist Collector and Oil Skimmer

FAQ

Q: What is the maximum bar stock diameter supported through the standard spindle bore?

A: The standard spindle bore is 82 mm, supporting a maximum bar capacity of 75 mm when utilizing standard hydraulic collet chucks.

Q: Can this lathe integrate with an automated gantry loader or robotic arm?

A: Yes. The electrical cabinet includes standard M-code integration ports, a hardware emergency stop interface, and fieldbus communication protocol slots for robotic cell handshaking.

Q: What maintenance schedule is required for the linear guideways and ballscrews?

A: The automatic lubrication pump dispenses oil at timed intervals based on spindle runtime. Operators must verify oil reservoir levels daily and check way-wiper seals monthly to prevent swarf ingress.

Q: How is thermal growth managed during extended multi-shift runs?

A: The headstock features ribbed cooling fins and optional spindle oil chiller units to stabilize bearing temperatures. The control unit applies automatic thermal compensation algorithms based on real-time thermistor feedback.

Q: What electrical power supply is required for installation?

A: Standard configuration requires 380V +/- 10%, 3 phase, 50/60 Hz. Custom transformers can be supplied for alternative regional requirements.

Q: What documentation is provided upon machine delivery?

A: Each machine includes electrical circuit diagrams, hydraulic schematics, PLC parameter lists, operational manuals, and an individual factory inspection test certificate.
