Introducing Acra's new 3680SET Precision Gap Bed Engine Lathe, a state-of-the-art machine that combines superior accuracy, durability, and versatility. Manufactured in Taiwan, this lathe is designed to tackle the most demanding machining applications with ease. With its robust construction, innovative features, and user-friendly design, the 3680SET is the perfect choice for manufacturers seeking to optimize their production processes and achieve exceptional results.
The Acra 3680SET Precision Gap Bed Engine Lathe is a testament to the company's commitment to quality and innovation. The headstock features heat-treated and precision-ground alloy steel gears and mandrel, ensuring smooth operation and long-lasting performance. The rotating type speed changing system allows for easy operation, while the large bore spindle, supported by 3-point precision bearings, is suitable for heavy-duty cutting.
The tailstock is equipped with a 2-speed quill, making it ideal for heavy-duty drilling, and the hand wheel features a dual dial type for added convenience. The apron and saddle boast an easy-to-operate overload safety protection device and a central lubrication system that can be operated manually or automatically. The universal gear box design enables the cutting of metric, imperial, and module threads without the need for changing gears.
The lathe bed is constructed from high-tensile rib's structure, ensuring high precision and a wide bed surface. The hardened and precision-ground one-piece structure enhances the machine's life and working performance. The auto longitudinal stop device controls the feed of the tool post, while the safe emergency brake system can shut off power supply simultaneously.
