CNC heavy duty lathe

CNC heavy duty horizontal lathe is a universal CNC lathe with half closed loop control function developed according to the latest development trend of CNC lathe in the international market. It is mainly used for the processing of shaft and disc solid of revolution made of cast iron, steel and other non-ferrous materials, using high-speed steel or carbide tools. It can complete the machining process of outer cylindrical surface, conical surface, curved surface, inner hole, end surface, grooving and so on, to meet the requirement of the workpiece rough and fine cutting

The distance between centers of the basic model is 8 m. Other models with distance between centers 3m, 4m, 8m, 9m, 10m,13m, 15m and so on. The models of distance between centers more than 12 meters are equipped with a piece of closed steady rest and a piece of open steady rest.

Note: swing over bed/distance between centers (5000mm – 20000mm) can be customized.

Characteristic

Chuck

Ф2200 mm heavy duty 4-jaw chuck is equipped.

The lathe adopts a heavy duty chuck and mechanical jaws with power clamping screws from JAKOB ANTRIEBSTECHNIK from Germany

Turret

The lathe is equipped with frame type turret. The frame turret is suitable to installed on heavy duty horizontal lathes for rough and finish cutting of various shaft parts, especially for heavy cutting (rough cutting) and cutting of stepped shafts, deep grooves and end faces. The tool plates are divided into main tool plate and auxiliary tool plate, which are arranged on the 2 sides of the frame type turret body. They can be independently extended and retracted, and they are fixed on the turret body with pressing plate. The extension length of the tool plate can be determined according to processing request. The tool plate moving mechanism is manually operated.

Tailstock

The tailstock consists of an upper body and a lower body. The upper body is equipped with tailstock spindle,  quill, and spindle center line adjustment mechanism. The lower body is equipped with tailstock movement mechanism. The tailstock is installed on the lathe bed. The tailstock is driven by the gear and gear rack to move longitudinally.

The tailstock spindle adopts NSK precision bearings. The front end of the spindle inside the tailstock is supported on double row radial roller bearing. It has the same structure with spindle with high rigidity. A disc spring is installed behind the spindle to prevent damage to the mechanism due to thermal expansion of the workpiece, and tailstock is equipped with a hydraulic force measuring device. There is a pressure gauge on the front and back of the tailstock. Operator can select and sets the appropriate pressure according to the weight of the workpiece and the tightening force label. The center of tailstock is a flange type short taper center.

The tailstock is motorized to approach to the workpiece with fast speed when the tailstock is far from the workpiece. The workpiece is clamped in axial direction manually by tailstock.

CNC Heavy Duty Lathe FAQ

What is a CNC heavy duty lathe used for?

A CNC heavy duty lathe is used for large shafts, rollers, cylinders, sleeves, and heavy industrial workpieces requiring high rigidity, stable cutting, and CNC-controlled turning.

How do I choose a CNC heavy duty lathe model?

Model selection depends on swing over bed, center distance, workpiece weight, spindle bore, chuck size, tailstock requirement, guideway width, and machining allowance.

Can the CNC heavy duty lathe be configured for long shafts?

Yes. Center distance, steady rests, follow rests, chuck, tailstock, and support method can be selected according to the long shaft drawing and weight.

What should I send for quotation?

Please send the workpiece drawing, maximum diameter, length, weight, material, machining process, tolerance, production quantity, and destination port.
