China Conventional Lathe Manufacturers Factory - Good Price Conventional Lathe for Sale

Product Overview

A conventional lathe rotates a cylindrical workpiece against a single-point cutting tool to perform turning, facing, boring, and thread cutting. Built around a Meehanite cast-iron bed with induction-hardened and ground ways (hardness >= HB450), this machine provides the mass and rigidity necessary to absorb chatter during heavy stock removal. Headstock gears are precision-shaved and oil-bath lubricated. Designed for low-to-medium volume production, toolrooms, and maintenance workshops where manual dexterity and quick setup outweigh CNC programming. Compliant with CE machinery safety directives.

Key Features

Bed Structure

One-piece Meehanite cast iron with heavily ribbed internal web architecture, mitigating thermal distortion and torsional flex under interrupted cuts.

Spindle Assembly

Supported by high-precision tapered roller bearings and angular contact ball bearings, maintaining radial runout within 0.009 mm at the spindle nose.

Geared Headstock

Hardened and alloy-steel gears mounted on splined shafts, delivering direct mechanical power transfer across 12 to 18 distinct speed steps.

Apron Mechanism

Interlocked feed rods and lead screws prevent simultaneous engagement of feed and threading functions, protecting gear trains from operator error.

Tailstock

Heavy-duty quill with Morse taper socket, equipped with a drift slot for rapid tool ejection and a positive locking lever.

Machining Capabilities

External & Internal Turning

Achieves dimensional tolerances down to +/- 0.015 mm on steel workpieces using carbide indexable inserts.

Facing & Parting

Rigid cross-slide travel supports steady feed rates during face turning and high-aspect-ratio parting-off operations.

Thread Cutting

Cuts metric (1 to 140 mm), Whitworth (2 to 56 TPI), module, and diametral pitch threads via quick-change gear box without swapping external change gears.

Taper Turning

Compound rest swivels +/- 60 degrees for short conical features; tailstock offset enables shallow long-taper turning.

Drilling & Boring

Tailstock quill accommodates drill chucks and boring bars for axial hole creation.

Application

Job Shops

Rapid turnaround for one-off shafts, bushings, and flanges where CNC programming time is uneconomical.

Tool & Die Maintenance

Re-machining worn pins, repairing gear shafts, and cutting custom fasteners.

Energy & Oilfield Sectors

Machining medium-length pipe fittings, valve bodies, and drill collars requiring large spindle bores (>= 100 mm).

Vocational Training

Teaching fundamental metal removal mechanics, manual coordinate reading, and tool geometry to apprentices.

How to Choose

Swing & Length: Match the maximum part diameter to the swing over bed. If machining parts with flanges, verify the swing in the removable gap. Select center distance based on typical shaft lengths, leaving 150 mm clearance for chuck and tailstock center.

Spindle Bore: Choose a 100 mm or 130 mm bore if passing oilfield pipe or heavy bar stock through the headstock is required; standard 52 mm suffices for general between-center work.

Bed Hardness: Confirm that induction hardening depth is at least 2 mm with a minimum hardness of HB450 to resist scoring from swarf and carriage friction.

Electrics & Compliance: Verify compliance with local grid voltages and safety standards (CE-compliant or UL/CSA-certified electrical control panels with low-voltage switchgear and footbrake power cutoff).

Manufacturing & Quality Control

01/

Foundry Practice: Meehanite cast iron undergoes sand-casting, stress-relief annealing, and natural aging for 90 days before machining to eliminate residual stress.

02/

Way Machining: Bed ways are milled on high-precision plano-millers, induction-hardened via medium-frequency coils, and precision-ground on 6-meter surface grinders.

03/

Spindle Geometrics: Spindles are forged from 40Cr alloy steel, normalized, carbonized, quenched, and ground on high-precision CNC cylindrical grinders.

04/

Inspection Protocol: Laser interferometer testing verifies bed straightness and lead screw pitch accuracy over full travel. Alignment tests measure spindle axis parallelism to carriage movement within 0.02 mm per 300 mm. Dynamic balancing of the spindle assembly ensures vibration limits remain below 1.5 mm/s.

Optional Configuration

Digital Readout (DRO): 2-axis or 3-axis glass scale DRO (Fagor or Sino) for real-time axis position tracking.
Chuck Options: 3-jaw self-centering chuck (320 to 400 mm), 4-jaw independent chuck (400 to 500 mm), or pneumatic/hydraulic chucks.
Steady & Follow Rests: Large-capacity steady rest (20 to 400 mm) and follow rest for long slender workpieces.
Tooling Systems: Quick-change tool post (Aloris or Dickson style) replacing the standard 4-way square tool post.
Coolant & Lighting: Built-in coolant pump (0.09 kW) with flood nozzles and low-voltage halogen or LED work light.

FAQ

Q: What is the maximum workpiece weight supported between centers without a steady rest?

A: Standard configuration supports up to 800 kg between centers (including chuck weight) for the 630 mm swing model. Workpieces exceeding this limit or with length-to-diameter ratios exceeding 10:1 require steady or follow rests to prevent deflection.

Q: Can this lathe cut both metric and inch threads without changing internal gears?

A: Yes. The enclosed quick-change gear box features an internal tumbler mechanism that shifts between metric (1 to 140 mm) and inch (2 to 56 TPI) settings via external levers.

Q: What electrical power requirements and safety certifications are included?

A: Requires a 3-phase, 380V (+/- 10%), 50Hz power supply, with optional factory transformers for 220V, 415V, or 480V grids. Electrical enclosures feature CE-compliant components, fused disconnect switches, and emergency footbrakes with immediate power cutoff.

Q: How is bed wear minimized over years of operation?

A: Bed ways are induction-hardened to HB450+ and pressure-lubricated via a manual or automatic pump system that delivers oil to the carriage sliding surfaces and lead screw bearings.

Q: What is included in the standard factory export packaging?

A: The machine is bolted to a fumigated wooden skid, wrapped in anti-corrosion VCI film, and sealed in a heavy-duty export plywood crate containing standard tools, manual, and test certificate.

Q: What documentation is provided with the machine shipment?

A: Each unit includes the operation manual, CE electrical schematic diagrams, lubrication diagrams, spare parts list, and the individual factory inspection test report certifying geometric alignment against ISO standards.
