CNC VTL Lathe for Motor Housings

CNC vertical lathes designed for motor housing machining feature a vertical rotary table configuration. After mounting, the workpiece weight helps improve positioning stability, making the equipment suitable for machining components such as aluminum alloy motor housings, cast iron motor bases, and drive motor housings for new energy vehicles.
The machine supports both roughing and finishing operations on critical features, including inner bores, end faces, locating surfaces, and bearing seats. By completing multiple operations in a single setup, it helps reduce positioning errors and improve machining consistency.
To meet strict requirements for the coaxiality of locating surfaces at both ends, end-face perpendicularity, and inner bore dimensional stability, these lathes can be equipped with dedicated fixtures and hydraulic clamping systems to ensure reliable positioning and continuous machining performance. Some machining solutions adopt a single-clamping, multi-operation process, reducing the cumulative errors caused by repeated workpiece repositioning in conventional machining methods.

A CNC vertical lathe for motor housing machining can typically perform the following operations:

Key Component Descriptions

Waterproof Hydraulic Chuck
The standard configuration includes a 12-inch waterproof hydraulic three-jaw chuck, with 18-inch and 24-inch chucks also available to suit different workpiece requirements. The chuck provides uniform clamping force, helping reduce deformation during the machining of thin-walled die-cast aluminum motor housings. A sealing strip is installed between the chuck jaws and chuck body to prevent coolant from entering the spindle area and to prevent chips from entering the sliding surfaces and causing wear. Three T-slots are provided on the chuck face for quick fixture installation and replacement.

Servo Turret
The machine tool is equipped with an 8-station servo turret, capable of mounting external turning tools, internal boring tools, end-face grooving tools, and chamfering tools. It enables multiple machining operations to be completed without frequent tool changes, effectively reducing machining cycle time. Servo-driven indexing combined with hydraulic locking ensures smooth operation and accurate positioning. A vertical turret is also available for specific machining applications, while a live tooling turret can be configured for drilling and other powered machining operations.

Independent Coolant System
The coolant system covers the machining area and machine bed, cooling the workpiece and cutting tools while flushing away chips generated during machining. The high-flow coolant circulation system quickly removes heat generated during high-speed precision turning of motor housings, helping maintain dimensional stability and reduce thermal deformation of aluminum alloy components. During heavy-duty roughing operations, it also improves chip removal performance, preventing aluminum chips from sticking to the workpiece and affecting surface quality.

Chain-Type Chip Conveyor
The machine is equipped with a chain-type chip conveyor designed to efficiently transport block and coiled chips generated during the machining of cast iron and stainless steel components. It collects and discharges chips centrally, reducing manual cleaning requirements and supporting continuous batch production in machining workshops.
