Types of Lathes
Here’s a complete table summarizing the types of lathes, including their key features, applications, and technological variations.
Types of Lathes |
||||
| Category | Lathe Type | Description | Key Features | Typical Applications |
| By Size & Capacity | Bench Lathe | Small lathe mounted on workbenches for precision work | <2 ft swing capacity, manual operation | Watchmaking, small precision parts |
| Engine Lathe | General-purpose center lathe with stepped pulleys/gearbox | 3-8 ft bed length, variable speeds | Shafts, bushings, prototyping | |
| Gap Bed Lathe | Removable bed section for oversized parts | Adjustable swing capacity (up to 50% increase) | Flanges, large pulleys | |
| Toolroom Lathe | High-precision engine lathe with accessories | Micrometer stops, taper attachments (±0.001″ tolerance) | Dies, gauges, precision tools | |
| Specialized | Turret Lathe | Hexagonal turret for multiple tool sequential operations | Rapid tool changes, semi-automatic cycling | High-volume bolt production |
| Capstan Lathe | Ram-type turret optimized for bar stock | Shorter stroke than turret lathes, faster cycle times | Small turned parts (screws, fittings) | |
| Swiss Lathe | Guide bushing for ultra-precision sliding headstock | <20mm part diameter, live tooling, multi-axis | Medical implants, watch components | |
| Automation Level | CNC Lathe | Computer-controlled with programmable toolpaths | Automatic tool changers, C-axis milling capability | Complex contours, mass production |
| Automatic Screw Machine | Fully automatic for mass production of small parts | Cam-operated, no operator intervention | Electrical contacts, fasteners | |
| Material-Specific | Wood Lathe | Designed for woodturning | Hand tool rests, higher RPM ranges (500-4000) | Furniture legs, bowls |
| Glass Lathe | Specialized for optical/laboratory glassware | Dual headstocks, gas torches for shaping | Lens blanks, test tubes | |
| Heavy Duty | Vertical Lathe | Rotating vertical table for massive parts | 10-40 ft diameter capacity, overhead cranes | Turbine rotors, large gears |
| Wheel Lathe | Dedicated for railway/vehicle wheel resurfacing | Outboard steady rests, laser alignment systems | Train wheels, mining truck rims | |
| Hybrid | Mill-Turn Center | Combined turning and milling capabilities | Y-axis, B-axis, subspindle | Aerospace fittings, complex manifolds |
| Multi-Spindle Lathe | Simultaneous processing with 4-8 spindles | 300+ parts/hour production rate | Automotive valves, hydraulic components | |
Technical Specifications Comparison |
||||
