China CNC Metal Lathe Suppliers Factory - Buy Customized CNC Metal Lathe

Product Overview

Our industrial CNC metal lathes are engineered for high-precision, continuous-duty rotational component manufacturing. Built on a heavily ribbed, Meehanite cast iron bed, these machines absorb high cutting loads and suppress thermal distortion. Designed for job shops and high-volume production lines alike, the platform integrates high-torque spindle architectures with rigid guideway configurations to maintain tight dimensional tolerances (plus or minus 0.005 mm) across extended machining cycles.

3-Axis CNC Metal Lathe (X15 Series)
The X15 Series CNC Metal Lathe is engineered for workshops and small manufacturers that need the precision and repeatability of multi-axis CNC machining without the footprint or cost of a full

Machine Types / Configurations

Selecting the correct lathe architecture dictates baseline rigidity and part complexity handling. We configure our machines to match specific production throughputs:

2-Axis Flat-Bed CNC Lathe:

Heavy-duty architecture optimized for large-diameter shaft turning, heavy stock removal, and toolroom applications.

Slant-Bed CNC Turning Center:

30-degree or 45-degree slant bed design facilitating unobstructed chip evacuation directly into the integrated conveyor, reducing thermal accumulation near the work zone.

Live Tooling / Milling Lathe (C-Axis plus Driven Tools):

Integrates off-center drilling, tapping, and milling operations in a single chucking setup, eliminating secondary transfer errors.

Sub-Spindle / Dual-Spindle Lathe:

Enables simultaneous front and back-machining of complex components, dropping completely finished parts in one cycle.

Machine Construction & Components

Machine longevity relies strictly on structural integrity and sub-assembly quality:

Bed Structure:

45-degree slant Meehanite cast iron, stress-relieved via thermal annealing and vibratory aging to eliminate internal stresses. Finite Element Analysis (FEA) optimized ribbing ensures high torsional rigidity.

Spindle Cartridge:

Cartridge-type spindle assembly supported by precision angular contact ceramic bearings (P4 grade), preloaded to handle heavy axial and radial loads up to 4,000 RPM.

Guideways:

Heavy-duty roller type linear guideways on X and Z axes (or hardened box ways on heavy-cut models), providing high damping capacity and smooth feed motion.

Turret:

8-station or 12-station servo-driven bi-directional indexing turret with face gear coupling, delivering repetitive indexing accuracy within 0.002 mm.

Tailstock:

Programmable hydraulic tailstock with built-in live center, quill thrust adjustable via software parameter to support long, slender workpieces.

Key Features

Thermal Compensation:

Spindle growth sensors and software compensation algorithms actively adjust Z-axis positioning to offset thermal expansion during long production runs.

Chip Management:

High-pressure coolant system (7 to 20 bar) paired with a dual screw-conveyor and rear-discharge belt system prevents chip bird-nesting in the machining chamber.

Control Integration:

Factory-wired for industrial CNC controllers (such as FANUC or Siemens platforms), featuring conversational programming and digital twin simulation support.

Rigid Clamping:

Hydraulic chuck with pressure safety interlock prevents spindle start when clamping pressure falls below threshold limits.

Manufacturing & Quality Control

Every lathe undergoes strict factory verification before shipment:

Foundry Verification: Ultrasonic testing of raw castings to verify internal grain structure density and detect micro-voids.

Laser Interferometer Calibration: X and Z axis pitch, yaw, and linear positioning verified using laser interferometers to guarantee international standard compliance.

Ballbar Testing: Circular interpolation testing to diagnose and correct servo mismatch, backlash, and geometric squareness.

Thermal Run Test: 48-hour continuous dry-run test at maximum RPM to monitor bearing thermal stability and vibration spectrum analysis.

Customization & OEM

We support OEM configurations tailored to specific production cells:

Automation Integration:

Custom interfaces for gantry loaders, articulated robots, and automatic bar feeders.

Specialized Workholding:

Custom jaw designs, precision collet chucks, and hydraulic steady rests for long shaft machining.

Tailored Bed Lengths:

Extended bed castings for specialized long-part turning requirements.

Frequently Asked Questions

Q: How do you prevent thermal growth from affecting dimensional accuracy during 24-hour production runs?

A: The machine utilizes a ribbed Meehanite cast iron bed that naturally absorbs and dissipates thermal energy uniformly. Additionally, the CNC controller runs real-time thermal compensation algorithms based on data captured from spindle housing sensors, actively correcting Z-axis ball screw expansion to maintain micron-level tolerances.

Q: What is the standard positioning and repeatability accuracy according to international standards?

A: Tested in accordance with ISO 230-2 standards using laser interferometers, standard lathes achieve a positioning accuracy of less than or equal to 0.008 mm over full travel and a repeatability of less than or equal to 0.003 mm. Calibration test charts are included with each machine shipment.

Q: Can this lathe be integrated with an automatic bar feeder or robotic loading cell?

A: Yes. Every machine is equipped with a standard electrical and M-code interface designed for seamless integration with bar feeders, gantry loading systems, and industrial robots. Custom PLC ladder integration can be pre-configured at the factory.

Q: What is the difference between linear roller guideways and box guideways on your lathe models?

A: Linear roller guideways offer higher rapid traverse speeds (greater than or equal to 24 m/min) and lower friction, making them ideal for high-speed precision turning of non-ferrous and standard alloy metals. Box guideways, featuring high surface-contact area, provide superior vibration damping and impact resistance, making them better suited for heavy interrupted cuts in hard materials like Inconel and titanium.

Q: What is the lead time for standard configurations versus custom OEM builds?

A: Standard off-the-shelf configurations typically ship within 4 to 6 weeks. Custom OEM builds, including specialized bed lengths, live tooling configurations, or integrated gantry systems, require 10 to 14 weeks, subject to engineering review and final drawing sign-off.

Q: What kind of technical documentation and after-sales support is provided upon delivery?

A: Each machine includes comprehensive documentation: electrical schematics, hydraulic diagrams, PLC parameter lists, parts manuals, and standard calibration certificates. For support, the engineering team provides remote diagnostics via Ethernet connection, localized spare parts inventory dispatch, and on-site commissioning services by factory-trained technicians.
