Introducing Acra's new 3660SET Precision Gap Bed Engine Lathes, a top-of-the-line machine designed for unparalleled accuracy, durability, and versatility in heavy-duty turning applications. These state-of-the-art lathes, manufactured in Taiwan and available from Omni Machine Inc. and other trusted distributors, deliver exceptional performance and reliability for a wide range of industries, including manufacturing, automotive, aerospace, and more. With their robust construction, advanced features, and user-friendly design, the Acra 3660SET Precision Gap Bed Engine Lathes are the ideal choice for workshops and facilities demanding the highest levels of precision and productivity.
The Acra 3660SET Precision Gap Bed Engine Lathes are engineered for superior performance and precision in heavy-duty turning applications. The headstock features all gears and mandrel made of heat-treated and precision-ground alloy steel, ensuring exceptional strength and accuracy. The rotating type speed changing system is easy to operate, allowing for quick and efficient speed adjustments.
The large bore spindle is supported by 3-point precision bearings, making it suitable for heavy-duty cutting. The tailstock, equipped with a 2-speed quill and a dual dial type handwheel, is ideal for heavy-duty drilling operations. The apron and saddle feature an easy-to-operate overload safety protection device and a central lubrication system that can be operated manually or automatically, ensuring smooth and reliable operation.
The universal gear box design enables the lathe to cut metric, imperial, and module threads without the need for changing gears, significantly reducing setup time and increasing productivity. The high tensile ribs structure, hardened and precision-ground one-piece lathe bed enhances the machine's life and working performance, providing high precision and a wide, stable bed surface.
The Acra 3660SET Precision Gap Bed Engine Lathes also feature an auto longitudinal stop, which controls the feed of the tool post, and a safe emergency brake system that shuts off power supply simultaneously, ensuring operator safety and machine protection.
