Product Overview

Our industrial metal lathes are engineered for precision turning, facing, and threading of ferrous and non-ferrous components. Built with high-grade Meehanite cast iron beds and precision-ground guide ways, these machines deliver rigid performance for high-load machining environments. Available in conventional engine configurations and advanced CNC setups, each unit undergoes strict geometric laser alignment and continuous load testing prior to factory dispatch.

Machine Types & Configurations

Conventional Engine Lathes:

Manual and semi-automated operation suited for tool rooms, maintenance shops, and low-to-medium batch production. Features quick-change gearboxes supporting both metric and imperial thread cutting.

CNC Flat Bed Lathes:

Equipped with industrial-grade CNC controllers for repeatable precision, automated multi-tool indexing, and complex contour turning.

Heavy-Duty Large Bore Lathes:

Designed for oilfield pipes, rollers, and long shaft processing, featuring enlarged spindle bores and dual-chuck configurations.

Machine Construction & Components

Bed Structure:

One-piece Meehanite cast iron base, frequency-induction hardened (HRC 50-55) and precision ground to minimize thermal distortion and absorb cutting vibration.

Spindle Assembly:

Supported by high-precision P5 class tapered roller bearings and angular contact ball bearings, ensuring radial runout of less than 0.008 mm.

Drive Train:

Hardened and precision-ground gears (ISO Grade 6) operating in an oil-bath lubrication circuit for smooth power transmission and extended service life.

Apron & Carriage:

Longitudinal and cross feeds driven by precision lead screws with adjustable bronze split nuts to compensate for wear.

Key Features

Rigid tailstock with MT4/MT5 Morse taper quill, equipped with a rapid locking lever and scale indicator.

Enclosed electrical cabinet featuring industrial contactors and internal cooling fans to prevent dust ingress and thermal overload.

Integrated coolant system with a high-flow pump and removable chip tray for efficient chip evacuation during high-speed cutting.

Full-length rear splash guard and interlocked chuck guard complying with safety standards.

Frequently Asked Questions

Q: What is the standard electrical supply required, and can the machine be configured for regional power?

A: The machines operate on standard industrial 3-phase power. Units can be built with transformers or dual-voltage motors configured for specific local voltage and frequency requirements, accompanied by compliant electrical components upon request.

Q: How do you ensure the long-term accuracy and straightness of the lathe bed?

A: The bed is cast from high-density Meehanite iron, subjected to natural aging and thermal stress-relief annealing. The guide ways are induction-hardened to HRC 50-55 and precision ground. This process ensures wear resistance and maintains geometric tolerances over years of heavy cutting.

Q: Are the threading gearboxes capable of cutting both metric and inch threads without changing gears?

A: Standard manual engine lathes feature a comprehensive gearbox that allows operators to switch between metric, inch, module, and diametral pitch threads simply by adjusting external selector levers, minimizing setup time.

Q: What inspection documentation is provided with each machine delivery?

A: Every metal lathe ships with an individual factory inspection test report. This document records specific measurements including spindle radial runout, parallelism of the tailstock quill to the spindle axis, and laser-verified lead screw accuracy.

Q: How are replacement parts and wearing components managed after purchase?

A: We maintain a complete inventory of standard wearing parts, including lead screws, bronze split nuts, drive belts, bearings, and pump assemblies. Common components are dispatched from stock to minimize customer downtime.

Q: What is the typical lead time for standard models versus customized CNC configurations?

A: Standard conventional engine lathes in common bed lengths (1000mm / 1500mm) typically have a production and crating lead time of 30 to 45 days. Customized CNC configurations or specialized voltage requirements generally require 60 to 75 days, including extended testing and burn-in cycles.
