Description

Product Overview

The ACRA 1743ACH is a precision gap bed engine lathe designed for toolrooms, repair shops, and general machining applications. With a 17″ swing and 43″ between centers, it offers compact versatility while maintaining high levels of accuracy.

The removable gap bed allows for increased swing over the gap, enabling larger diameter workpieces without requiring a larger machine.

Applications

  • Toolrooms and machine shops
  • Maintenance and repair work
  • Small to medium part machining
  • Custom and one-off jobs

👉 Gap bed lathes are ideal when shops occasionally need larger diameter capacity without upgrading to a bigger machine

Key Features

  • 17″ swing over bed for compact versatility
  • 24″ swing in gap for oversized parts
  • 43″ between centers for general shop work
  • 2-1/4″ spindle bore for standard material sizes
  • 7.5 HP motor for reliable performance
  • 12 spindle speeds (35–2000 RPM) for flexibility
  • Precision-ground and hardened components for accuracy
  • 3-point bearing spindle support system
  • Universal gearbox for inch and metric threading
  • Includes chuck, steady rest, coolant system, and tooling

Why This Machine Matters

Standard small lathes:

  • Limit diameter capacity
  • Lack rigidity
  • Require upgrading for larger jobs

The 1743ACH solves this by:

  • Providing extra swing with the gap bed
  • Maintaining precision for everyday work
  • Keeping a compact footprint

👉 This makes it ideal for shops that need flexibility without oversizing.

When to Use This Lathe

  • When machining small to medium parts
  • When occasionally needing larger diameter capacity
  • When working in a toolroom or repair shop
  • When upgrading from a light-duty or hobby lathe

What is a Gap Bed? (important for buyers)

A gap bed lathe includes a removable section near the headstock:

  • Gap installed → standard operation
  • Gap removed → increased diameter capacity (up to 24″)

👉 This is the main advantage of this machine

Specifications

  • Swing Over Bed: 17″
  • Swing In Gap: 24″
  • Distance Between Centers: 43″
  • Spindle Bore: 2-1/4″
  • Spindle Speeds: 35–2000 RPM (12 speeds)
  • Motor: 7.5 HP
  • Spindle Nose: D1-6
