Introducing Acra's 14"/21" x 40" Precision Variable Speed Gap Bed Engine Lathes, a high-quality machining solution made in Taiwan. These lathes are designed to deliver exceptional performance, precision, and versatility, making them an ideal choice for a wide range of turning applications in various industries.

Acra's 14"/21" x 40" Precision Variable Speed Gap Bed Engine Lathes are engineered for superior accuracy and reliability. The lathe's robust construction features a one-piece Meehanite casting base that has undergone vibration stress relief, ensuring maximum stability and reduced vibration during operation. The bed ways are induction hardened and precision ground, providing a durable and accurate foundation for the carriage. A precision hand-scraped removable gap allows for increased swing capacity, while Turcite B coating between the bed and carriage enhances smooth movement and reduces wear.

The spindle is supported by two precision taper roller bearings and one ball bearing, ensuring high rigidity and accuracy. The dynamically balanced, hardened, and precision-ground spindle features a D1-6 spindle nose and a generous 2-1/6" diameter bore, accommodating a wide range of workpieces and tooling. The apron and saddle offer automatic feed and threading capabilities, with fully interlocked mechanisms and a convenient saddle and top slide locking system. A 4-way tool post provides quick and easy tool changes, enhancing productivity.

The lathe is equipped with a 5 HP 4-pole AC inverter drive, offering a wide range of spindle speeds from 20 to 2,800 RPM across two ranges. The conveniently located control panel features a digital RPM meter, allowing for precise speed control and monitoring. The universal gearbox, with oil bath lubrication and heat-treated precision ground gears, enables the cutting of inch, metric, module, and diametrical threads. The headstock features a pressurized lubrication system, ensuring optimal lubrication of the chromium molybdenum, heat-treated, and precision-ground gears.
