+Manual Lathe
Manual lathe, also known as conventional lathe, hand-operated lathe, is a conventional metal cutting machine tool, is also one of the most widely used machine tools, accounting for about 65% of the total number of lathes. It is mainly used for turning by rotating the workpiece and following a straight path with a single-edged tool to produce accurate cylindrical, conical or shaped external surfaces.
Manual Lathe Structure
Manual Lathe Structure Performance
Manual lathes feature a horizontal structure with high power and robust rigidity, providing a wide range of spindle speed adjustments. This makes them suitable for heavy-duty or high-speed cutting operations. They are capable of performing a variety of machining processes, including turning the inner and outer cylindrical surfaces, taper surfaces, and end faces of shafts and discs, as well as grooving, chamfering, drilling, and tapping. Additionally, manual lathes can handle threading operations for metric, imperial, module, diametral pitch, and taper threads. The tool post allows for the motorized turning of short tapers, while the combination of longitudinal feed and tool post feed enables the machining of long tapers, demonstrating exceptional capabilities in handling large and complex parts.
By focusing on these versatile functionalities, manual lathes are highly regarded for their adaptability in various machining tasks, making them an indispensable choice for workshops needing precision and flexibility.
Key Structural Features
This lathe utilizes a traditional horizontal layout with an integrated design that ensures excellent rigidity and compliance with safety standards. Major foundational components, such as the bed and headstock, are made from resin sand castings that undergo manual aging treatment, providing exceptional overall stability. The bed is constructed from HT300 cast iron, and the bed guideways are induction-hardened to a hardness of HRC48, significantly enhancing the longevity of the guideways.
The lathe's headstock is designed with centralized control handles for easy and flexible operation. The spindle system utilizes a three-point support structure, ensuring high precision and strong rigidity in the front and rear bearings. The spindle's braking and forward/reverse rotation are hydraulically controlled, providing responsive and reliable braking. Speed changes can be made without stopping the machine, using a push-button for seamless operation. The headstock is equipped with a forced lubrication system using pressure oil, contributing to its aesthetically pleasing appearance, excellent rigidity, high precision, smooth operation, low noise, ease of assembly, and minimal spindle thermal deformation.
The tailstock sleeve features a metric bore of φ75 mm and utilizes a top clamping mechanism, ensuring reliable clamping and enhanced overall rigidity of the tailstock. Additionally, options for tailstocks with a φ200 mm or φ240 mm rotating spindle are available, providing users with flexibility to choose according to their specific machining needs.
The lathe is equipped with a full range of functionalities, offering easy operation, stable precision, and reliable performance. It also features an aesthetically pleasing and elegant overall design.

Manual Lathes Types
Manual lathes come in various types, each designed for specific machining tasks. Below are some common types of manual lathes:
- Engine Lathe: The most common and versatile type of lathe, suitable for a wide range of tasks such as turning, facing, drilling, and threading. It is often used for machining workpieces of varying sizes.
- Turret Lathe: Equipped with a rotating turret that allows quick switching between multiple tools, making it ideal for repetitive production tasks.
- Toolroom Lathe: A high-precision lathe used for fine machining and the manufacture of small, complex parts, typically employed in tool and die making.
- Bench Lathe: A smaller version of the engine lathe, designed to be mounted on a workbench. It is suitable for light-duty machining tasks and small workpieces, commonly found in workshops or hobbyists’ workspaces.
- Gap Bed Lathe: Features a removable or adjustable bed section to accommodate large-diameter workpieces, suitable for parts that cannot be clamped on a standard lathe.
- Speed Lathe: A simple lathe without automatic feed or carriage, primarily used for woodturning, metal spinning, and polishing, typically operated at high speeds.
- CNC Cam Lathe: Similar to a turret lathe but better suited for mass production, capable of quickly producing identical parts with minimal setup time.
Each type of manual lathe is designed for specific applications and offers unique advantages based on machining needs. If you are unsure which type of lathe is suitable for your needs, you can provide your workpiece drawings or the model of the machine you previously used, and our professional engineers can offer you more tailored advice!
