China Customized Lathe Machine Manufacturers Factory - Lathe Machine for Sale

Short Introduction

Industrial lathe machines execute precision material removal for cylindrical components across automotive, aerospace, and energy sectors. Rigid Meehanite cast iron beds dampen cutting vibrations to hold strict geometric tolerances under continuous multi-shift production. Configurations span from flat-bed manual lathes for toolroom flexibility to high-torque 3-axis CNC systems for automated component manufacturing.

Lathe Machine Types & Configurations

Slant-Bed CNC Lathes

30-to-45-degree bed inclination routes chips directly into lower conveyors while providing high structural stiffness for aggressive roughing passes.

Flat-Bed CNC Lathes

Manual machine architecture paired with CNC controls, engineered for long shaft turning and job-shop batch flexibility.

Heavy-Duty Horizontal Lathes

Large-swing capacity exceeding 800 mm swing over bed, built for oilfield pipe threading, marine driveshafts, and heavy structural rolls.

Swiss-Type Sliding Headstock Lathes

Designed for high-precision, small-diameter components with live tooling for simultaneous turning and milling.

Key Features

Meehanite Cast Iron Base

Single-piece ribbed casting annealed at 600 deg C to eliminate residual stress, preventing thermal deformation during heavy material removal rates.

C3-Class Ball Screws

Pre-tensioned double-nut ball screws direct-coupled to servo motors eliminate mechanical backlash and maintain linear repeatability.

Cartridge-Type Spindle Assembly

Supported by P4 angular contact ball bearings and dynamically balanced to G1.0 grade to suppress vibration at maximum spindle speeds.

Hydraulic Turret

8-station or 12-station bi-directional indexing turrets deliver tool change times under 1 second with clamping repeatability within 0.002 mm.

How to Choose the Right Lathe Machine

Workpiece Envelope

Match maximum swing diameter and distance between centers to raw stock dimensions plus jaw and tailstock clearance.

Material Removal Rate

Specify slant-bed configurations with high torque output for high-alloy steels, titanium, and heat-resistant superalloys.

Control System Selection

Match CNC architecture, such as Fanuc 0i-TF or Siemens 828D, to existing shop-floor programming standards and operator familiarity.

Automation Provisions

Evaluate integration needs for bar feeders, gantry loaders, or robotic interfaces for lights-out manufacturing.

Typical Applications

Automotive

Transmission shafts, CV joint components, and steering knuckles machined from forged steel and aluminum billets.
Aerospace

Turbine compressor rings, actuator bodies, and landing gear struts requiring IT6 geometric precision.
Oil & Gas

Drill collars, tool joints, and casing couplings machined to API specification threads.
General Engineering

Hydraulic cylinders, pump shafts, and industrial drive rollers.

Manufacturing & Quality Control

01.

Casting Seasoning

Raw iron castings undergo 30-day natural aging followed by thermal stress-relief annealing prior to finish machining.

02.

Guideway Induction Hardening

Box ways are induction-hardened to HRC 50 to 55 and precision-ground on 6-meter CNC surface grinders.

03.

Laser Interferometer Verification

Linear axis compensation and pitch error correction are mapped using Renishaw laser interferometers before factory sign-off.

04.

Ballbar Circular Testing

Dynamic circular interpolation tests check servo mismatch, reversal spikes, and axis squareness under simultaneous X and Z axis motion.

Configuration & Options

Material Compatibility

Carbon steel, alloy steel, stainless steel, ductile iron, bronze, and titanium alloys.

Dimensions

Bed lengths scalable in 500 mm increments up to 6000 mm between centers.

Tolerance Capability

Dimensional tolerances down to plus or minus 0.005 mm and surface finish Ra 0.4 um under climate-controlled conditions.

Production Volume

Job-shop batch runs of 10 to 500 parts up to dedicated automated production cells.

Machining Process Options

Rough turning, finish profiling, internal and external threading including metric, inch, NPT, and API, parting, and eccentric grooving.

Optional Accessories

Hydraulic chucks, live tooling holders, hinge-type chip conveyors, bar feeders, and 20-bar high-pressure coolant systems.

FAQ

Q: What is the maximum achievable workpiece straightness over a 2000 mm turning length?

A: With correct machine leveling, shop-floor thermal stabilization, and stable cutting parameters, standard heavy-duty CNC lathes hold cylindrical straightness within 0.015 mm over a 2000 mm span.

Q: Can this machine handle interrupted cuts on forged steel components?

A: Yes. The heavy-ribbed Meehanite cast iron bed and high-torque spindle motor absorb shock loads effectively during roughing passes on unmachined forgings or castings.

Q: What electrical power supply configurations are available for site installation?

A: Standard configuration requires 3-phase, 380V to 480V with a plus or minus 10 percent tolerance at 50Hz or 60Hz. Custom step-down or step-up transformers can be integrated into the main electrical cabinet to match regional grid specifications.

Q: How are critical replacement components and spindle bearings sourced locally?

A: Spindle bearings utilize international standard P4 precision grades from brands such as NSK or FAG. Hydraulic valves from Rexroth or Yuken and electrical switchgear from Schneider are globally sourced for local interchangeability.

Q: What routine maintenance is required to sustain positioning accuracy over time?

A: Automatic metered lubrication pumps deliver oil to guideways and ball screws every cycle. Operators must verify fluid levels daily, clear chip pans per shift, and execute quarterly backlash checks via CNC diagnostic routines.

Q: What documentation is provided during the Factory Acceptance Testing stage?

A: FAT deliverables include a 72-hour dry-run stress test report, geometric accuracy inspection certificate, laser interferometer calibration data, and a trial-cut sample inspected on a Coordinate Measuring Machine.
