CW61100B / CW61125B / CW61140B / CW61160B Series Heavy-Duty Lathe

Description

CW61100B/61125B/61140B/61160B Series Heavy-Duty Lathes

The CW61100B/61125B/61140B/61160B series heavy-duty lathes are designed to handle workpieces weighing up to 6 tons. These machines are capable of comprehensive turning operations, including facing, external and internal cylindrical turning, and cutting a wide range of threads (metric, inch, module, and diametral pitch). The top slide can be independently motorized for machining short tapers, or combined with longitudinal feed for long taper turning. Furthermore, these lathes can perform drilling, trepanning, boring, and similar processes. With their high power and robust rigidity, these machines can effectively utilize cemented carbide tools for thread cutting and machining various ferrous and non-ferrous metals.

Key Features:

1. High-Rigidity Integral Bed: The machine bed features a robust, integral cast structure. Its optimized internal rib layout provides exceptional rigidity. The guide rails undergo medium-frequency quenching and precision grinding. Anti-stick-slip guide plates are applied to the sliding guide surfaces, ensuring optimal dynamic characteristics such as friction damping and preventing low-speed crawling.

2. High-Rigidity, High-Precision Spindle: The headstock employs a symmetrical design to ensure uniform thermal expansion, preventing any displacement of the spindle center. To further minimize thermal deformation, the headstock utilizes an oil bath circulating lubrication system. The spindle’s front end is supported by a robust three-bearing structure, incorporating bi-directional angular contact ball bearings, which significantly enhances both precision and rigidity. All gears within the headstock are precision-quenched and ground, guaranteeing accurate power transmission, low noise levels, and maintaining consistent accuracy during prolonged operation.
