Product Overview

The C6140D / C6240D series is a robust manual gap bed engine lathe engineered for higher capacity precision turning. With a 400mm swing over bed and 580mm swing in the gap, these conventional lathes offer greater versatility than smaller models, making them ideal for machining larger diameter short workpieces as well as shafts up to 1500mm. Built with hardened guideways and precision components, the C6240D gap bed lathe delivers reliable performance for workshops, maintenance departments, and small-to-medium manufacturing.

Key Features and Benefits

Key Features:

  • Larger Swing Capacity: 400mm swing over bed and 580mm maximum swing in the gap (200mm valid gap length) – perfect for turning big flanges, pulleys, and discs.
  • High Rigidity Bed: 320mm wide bed with guideways hardened to over HRC52 and precision ground by CNC grinder for excellent stability and accuracy.
  • Powerful Spindle: 46mm spindle bore (45mm bar capacity), C6 nose, MT6 taper, and 25–1600 rpm across 12 speed steps.
  • Versatile Thread Cutting: Supports metric (0.45–20mm, 30 kinds), inch (35 kinds), module (25 kinds), and diametral pitch (30 kinds) threads.
  • Precision Construction: Critical parts machined on Spanish CNC machining centers; low-noise CNC ground gears for smooth and quiet operation.
  • Flexible Tailstock: MT4 taper, 130mm quill travel, and ±10mm offset for easy taper turning.

Benefits:

  • Higher machining capacity for larger workpieces compared to 350mm swing models
  • Excellent rigidity and vibration resistance for better surface finish
  • Reduced maintenance and long service life thanks to high-quality components
  • Great value and versatility for general machining workshops

Frequently Asked Questions (FAQ)

Q1: What is the difference between C6140D and C6240D? A: C6240D is the gap bed version offering larger swing in the gap (580mm), while C6140D is typically the straight bed model. Both share the same core specifications.

Q2: How does the C6240D compare to the C6232D? A: The C6240D has a larger 400mm swing over bed and 580mm swing in gap, making it suitable for bigger diameter workpieces. It is the upgraded, higher capacity model in the series.

Q3: What is the spindle bore size on the C6240D? A: The spindle bore is 46mm, allowing bar stock up to 45mm in diameter.

Q4: Can this lathe cut both metric and inch threads? A: Yes, it supports a wide range: 30 metric, 35 inch, 25 module, and 30 diametral pitch threads.

Q5: Is the gap bed removable? A: Yes, the gap section can be removed to allow full-length turning on the bed.
