Lathe Machines and Metal Lathes

Lathe Machines and CNC Lathes for Mining, Heavy Engineering and Production

A lathe machine rotates a workpiece against a stationary cutting tool to produce cylindrical shapes such as shafts, spindles, bushings and threaded components. With the right tooling, it also produces complex contours, internal bores and faced surfaces to tight tolerances. Whether for mining and minerals processing, heavy engineering, repair work or a training workshop, KNUTH offers a lathe to match the task.

Turning comes down to two basic movements. Longitudinal turning removes material along the workpiece axis and creates the outer form. Facing works across the axis and creates flat end surfaces. Modern machines combine both operations across several axes. That makes turning one of the most versatile processes in any workshop.

Types of Lathe

The range runs from compact conventional machines to fully automated CNC lathes. The right type depends on your parts, your batch sizes and your operators.

• Conventional lathes: Controlled manually by the operator. Ideal for single parts, repairs, prototypes and vocational training. Manual control builds a solid understanding of the turning process before moving to CNC. Servo-conventional models add electronic feeds and infinitely variable speed for smoother operation.
• Heavy-duty lathes: A rigid bed for large, heavy workpieces, with swing over bed up to 1,600 mm and workpiece lengths up to 8,000 mm between centres. A common choice for mine maintenance, rolling stock and heavy engineering, where shafts, rolls and pins are turned and reconditioned.
• CNC slant-bed lathes: The inclined bed improves chip evacuation and access to the work area. With CNC control, high repeatability and short cycle times, they are the standard for precision parts in series, for example in automotive, agricultural equipment and general engineering.
• Vertical lathes: The vertical spindle makes it easier to mount large, heavy or unwieldy workpieces such as flanges, rings, slew gears and large pulleys that are difficult to position horizontally. On KNUTH conventional vertical lathes, turning diameters reach up to 2,600 mm.

Key Specifications Compared

When comparing lathes, a few figures decide whether a machine suits your work:

• Swing over bed: The largest workpiece diameter that can rotate over the bed without contact. At KNUTH from 200 mm on bench models up to 1,600 mm on heavy-duty lathes.
• Distance between centres: The maximum distance between headstock and tailstock, and therefore the longest workpiece. At KNUTH up to 8,000 mm on heavy-duty machines.
• Spindle bore: Decisive for bar work. The bore must be larger than the bar diameter.
• Drive power and spindle speed: Hard materials and large diameters need more power, soft materials and small parts less.
• Control: Conventional, cycle-controlled or CNC with Siemens or Fagor.
• Accuracy and repeatability: The precision you can hold from part to part.

The KNUTH product pages list these figures for every model, so you can match a machine to your tolerances and your floor space before you enquire.

Lathe Accessories and Tooling

The right accessories determine how precisely and efficiently a lathe performs. Chucks hold the workpiece: three-jaw chucks for round stock, four-jaw chucks for off-centre clamping, collet chucks for the tightest tolerances. Tool holders and quick-change toolposts cut setup time, and boring bars handle internal work. Steady rests and follow rests support long workpieces against deflection. KNUTH advises on the right accessory package, so you do not pay for capacity you will not use.

Industrial Applications

Lathes are central to almost every sector that works metal:

• Mining and minerals processing: Turning and reconditioning shafts, pins, rolls and bushings for plant and equipment.
• Heavy engineering: Large cylindrical components for structural and mechanical assemblies.
• Cylindrical parts: Shafts, bolts and bushings for assembly into machinery and equipment.
• Precision machining: Exact dimensions and surface finishes for automotive, agricultural and general engineering.
• Repair and maintenance: Turning down worn parts, recutting threads, restoring damaged surfaces.
• Series production: Consistent batches on CNC lathes.
• Training: Teaching the fundamentals of metal cutting.

Why KNUTH

KNUTH has supplied machine tools to metalworking businesses worldwide since 1923. Our machines are built for daily use in demanding environments, with a focus on long-term reliability, easy maintenance and consistent performance. That gives you European quality without the European price. Across sub-Saharan Africa, KNUTH operates through a network of local service partners for installation, support and spare parts.

Comprehensive Service: Commissioning, Training, Repair

We support you through the installation and commissioning of your new lathe and train your team on its operation. On-site commissioning covers installation, levelling, electrical connection, initial calibration and a spindle runout check. Our technical support and repair service covers every machine category in the KNUTH range. For CNC machines we offer remote maintenance through the control manufacturer's module. Our spare parts inventory ships most components quickly, including for older machines.
