BT500B Heavy-Duty Lathe: Programmable Precision for Demanding Workpieces

The BT500B is a heavy-duty lathe engineered for workshops that require high rigidity and programmable control. With a maximum turning diameter of Ø500 mm and a swing over cross slide of Ø325 mm, it handles large shafts, flanges, and cylindrical parts with ease. The gap bed design further extends capacity, allowing a swing of Ø630 mm in the gap over a valid length of 260 mm.

Built for Heavy Cuts and Threading Versatility

The BT500B features a 330 mm wide bed and a 5.5 kW motor, providing the stability needed for heavy stock removal. The 15-step spindle speed range from 22 to 1800 rpm allows optimal cutting speeds for various materials. With 66 metric and 66 inch thread options, plus 33 diametral and 33 module pitches, this lathe covers a wide range of threading requirements without additional attachments.

Programmable Operation

As a programmable lathe, the BT500B offers automated control for repetitive turning operations. This reduces operator fatigue and improves consistency across production runs. The ISO-D6 spindle nose and MT6 spindle bore accept standard tooling, while the MT5 tailstock quill supports drilling and center work.

Available Configurations

Choose from four distance-between-centers options: 1000 mm, 1500 mm, 2000 mm, or 3000 mm. Each configuration is packed in a sturdy case with dimensions tailored to the bed length. The lathe operates on 380–440 V three-phase power, with a 90 W coolant pump for efficient chip removal and surface finish.

Applications

Ideal for general machining, repair shops, and production facilities handling large parts. The gap bed allows turning of larger diameter workpieces that would otherwise require a bigger machine. Typical uses include shaft turning, facing, boring, and thread cutting on steel, cast iron, and non-ferrous metals.
