Description

Product Overview

The Kingston KMT-4V is a heavy-duty vertical milling machine designed for precision machining and production environments. With a 10″ × 50″ table, variable speed head, and box way construction, it delivers superior rigidity and accuracy compared to standard knee mills.

Built with Meehanite castings and precision-ground components, the KMT-4V is engineered for long-term performance, making it ideal for demanding machining applications.


Applications

  • Machine shops and toolrooms
  • Precision part machining
  • Production environments
  • Heavy-duty milling and fabrication

👉 Ideal for shops requiring higher rigidity and accuracy for demanding work


Key Features

  • 10″ × 50″ hardened and ground table
  • Square/box ways on Y and Z axes for increased rigidity
  • 3 HP motor for strong cutting performance
  • Variable speed spindle (60–4200 RPM)
  • R8 spindle taper for standard tooling
  • Class 7 precision spindle bearings
  • Maximum spindle runout approx. 0.0002″
  • Meehanite cast iron construction for stability
  • Turcite-B coated sliding surfaces for smooth movement
  • Hardened and ground ways for durability
  • Heavy-duty saddle support across full table width
  • One-shot lubrication system for easy maintenance

Why This Machine Matters

Standard knee mills (like KMT-3V):

  • Good general performance
  • Less rigid under heavy cuts

The KMT-4V improves on this by:

  • Using box ways for superior rigidity
  • Handling heavier cutting loads
  • Maintaining higher accuracy under stress

👉 This makes it a true production-capable manual mill


When to Use This Machine

  • Heavy milling operations
  • Production machining
  • Precision toolroom work
  • Shops needing more rigidity than standard mills

Specifications
