3 ModelsPrecision Manufactured Wide Range of Accessor ies High Accuracy Rotation Range of Bed Lengths > Description Base For all Arc Welding Processes > All Jetline precision lathes are based upon the same concept to assure precision with strength. Each lathe's design incorporates an anodized, extruded aluminum base. This extrusion holds two precisely parallel, hardened and ground roundways. The roundways form a track on which the headstock is mounted and on which the tailstock and torch mounting carriage move. To assure rigidity, the extruded aluminum section is mounted to a rectangular, structural steel tube with mounting pads. Introduction The Jetline range of precision lathes is designed and built to provide superior accuracy and per- formance for even the most demanding applica- tion.Many competitive models of precision lathes are manufactured using a standard machining center lathe which is modifi ed for welding purposes. This type of approach limits the capabilities of the lathe and does not produce the ideal product for demanding welding applications. To overcome this problem, Jetline designed a precision welding lathe which is custom manufactured from the base up. While still providing the accuracy demanded of this type of lathe, the unit also has other important features. These include the following: The facility to use multiple welding heads on the same lathe. The ability to carry heavy loads. Multiple choice of bed lengths with extra-long beds available to order. Special head and tailstock confi gurations.Three models are available varying in load carrying capacity, from the smallest at 100 lbs (45 kg) to the largest at 500 lbs (225 kg). The standard feature for all models is the rotational and linear accuracy. All models feature precision hardened and ground lathe beds, headstock and tailstock spindles. Headstock The headstock is fabricated from a solid housing of aluminum. This is machined to accurately fi t on the roundways, to which it is secured. The headstock housing is accurately bored to accept the precision ground headstock spindle. The spindle has a through-hole and rotates in the headstock housing on pre-loaded, tapered roller bearings. The bearings are designed to provide smooth, precise rotation and, because they are pre-loaded, also have the ability to carry the welding current. A stud is provided on the headstock housing to connect the welding ground cable.The headstock spindle is driven through a tensioned timing belt by a high-quality DC servo motor fitted with a tach-generator. The unique 9640 microprocessor drive control uses menu-driven software to permit the setting of rotational speed and the delays for the starting and stopping of travel. The control indicates speed before and during welding, if the diameter of the part is entered, the indicated speed will be surface speed. Speed holding accuracy of the standard model is +1% of the rated speed. The spindle is fi tted with a mounting fl ange to permit the use of a self- centering chuck, a collet holder or a faceplate. 15 Goodyear St, Irvine, California 92618 U.S.A.

The tailstock rides on the base using four recirculat-ing ball bearings. They provide smooth, accurate movement along the precision ground roundways on the bed of the lathe. A lever is provided to lock the tailstock carriage when it is in its desired position. The tailstock spindle extends to clamp the part for welding; extension is achieved using an air cylinder with adjustable fl ow valves to control the speed of movement of the spindle. Clamping pressure is adjustable; activation of the spindle movement is by a manual air valve.The tailstock spindle has a Morse taper bore to ac-commodate...

A manufacturer of thermocouples and sensors for the Aerospace industry had a need to circumfer- entially weld small parts made of stainless steel and Inconel. A leading manufacturer of automotive air bags had a need to produce one million cylinders per year. Each cylinder consisted of a body, a base, and a head. They were welded using two circum- ferential welds. > A CWP1-6 precision lathe answered the need per- fectly. Controlled by Jetlines 9500 Microprocessor Controller, the rotational speed of the lathe and the output of the GTA (TIG) welding power supply were maintained within very...
