ACER DYNAMIC 2160S MANUAL LATHES

Technical Description

The ACER Dynamic 2160S Manual Lathe is a high-precision engine lathe designed for heavy-duty machining tasks. It features a **20.5-inch swing over bed** and a **59-inch distance between centers**, enabling it to handle large workpieces with ease. The lathe is equipped with a **3.1-inch spindle bore** (MT #7 taper) and a D1-8 spindle nose, supporting robust spindle throughput and tooling versatility. Powered by a **7.5 HP main motor** (with a 10 HP option available), it delivers significant torque for demanding cutting operations, achieving spindle speeds from **20 to 2,000 RPM** across 12 stepped settings for precise speed control. The **swing over cross slide is 13 inches**, allowing for substantial machining diameter over the cross slide. The bed is constructed of thermally treated Meehanite casting with a hardness rating of HS70 for durability and vibration resistance. The lathe’s carriage, cross slides, and saddle are precision-ground and hardened to ensure smooth, accurate movements. Threading capabilities include inch threads from 4 to 56 TPI and metric threads from 0.5 to 7 mm pitch, with automatic feed and threading functions interlocked for operational safety. Additional features include a 1/8 HP coolant pump, tailstock with 5.9-inch travel and 2.7-inch barrel diameter, and options for hydraulic quill operation. The lathe's overall footprint is approximately 104" x 32" x 48", with a weight around 4,700 lbs. This model combines rigid construction, high power, and precision engineering to meet rigorous industrial machining demands.
