3 ATV-618-ET ATV-618-ET Shown with some options Faster Lever Collet Closer The lever collet closer provides fast chucking. The lever control end of the closer assembly is balanced and rides on a precision bearing. Collet tension is instantly adjustable throught the rull range from light to heavy holding power without the use of tools. Standard Equipment Electronic threading with micro processing controls. 2- Axis digital readout system Complete 3/60/220 volt electrics with 110 volt controls and thermal overload protection. Flood coolant pump and nozzle Standard 5C collet closer (manual) Inch/metric dual dials Welded steel pedestal/cabinet Work light Test bar Leveling pads Tool setting gage Drive dog plate Headstock center Standard Tools Dual Dials and Gearbox for Inch/Metric Threading The dual gearbox provides high accuracy english or metric thread cutting. The gearbox and lead screw operate only when used for threading operations. With standard change gears. Pitches are available from 275 to 2.7 mm. Optional change gears available at extra cost. Independent Electric Variable Feeds(D.C.) Independent Electronic Variable Feeds. The drive for the carriage is independent from the cross slide and provides complete freedom of operation. The feed can be changed instantly at any time. Simply turn a knob even when the tool is cutting without wasting valuable production time stopping the machine to shift gears. Quick-Acting Tool Post Slide The quick-acting tool post slide for threading is standard eqipment. T the end of the threading cut, the threading tool is instantly cleared from the work by the operator for the return of the carriage to the next cut. This is accomplished by means of the ball-handled lever actuating the tool post slide entirely independent of the tool post slide feed screw. 2

There is no weakness of a center slot. There is one precision straight edge for aligning and anchor attachments. The bed is easy to keep clean, will resist wear, and chips cannot fail upon the angular guide ways. Double Tool Cross Slide The cross slide base provides the needed rigidity when forming, cutting off, or turning with the straight and taper turning slide attachment. The cross slide is easily operated by a hand lever. Two threaded feed stops are provided for fine adjustment of each tool position. Spindle Drive Unit The unit provides variable speeds from 230 to 3,500 RPM. To change spindle speed, start the spindle and push the faster or slower button. This will increase or decrease the spindle speed. High and low Spindle speed setting are instantly available with a lever operated two speed motor. Six - Station Turret The preloaded ball bearing turret head mounting, eliminates all play between the turret head and turret slide. The index pin is hardened and ground, and is mounted between hardened and ground preloaded roller bearings for ease in operation. The turret head and each of the six independent adjustable stops are automatically indexed to the next position. 3

Fast Lever Collet Chucking The lever control ended of the closer assembly is balanced and rides on a precision bearing. Movement to the left closes the collet, and to the right opens the collet. Hardened and Precision Ground Steel Ways The bed ways are solid hardened and ground steel. There is no weakness of a center slot. The bed is easy to keep clean, will resist wear, and chips cannot fall upon the angular slide ways. Quick Change Spindle Speeds Spindle speeds are provided of 750, 1,800 and 3,000 RPM through an endless V-belt and three step pullet arrangement. Spindle speeds are quickly changed. Raise the pulley and belt cover as shown. Move the lever horizontally to the extreme left. This will slide the motor pulley to the belt release position. Change belt to the pulley step desired and return the lever to the extreme right or belt tight position. 4

6 AT-914-HC ATV-914-HC Shown with some options Standard Tools Standard Equipment Ball bearing 5C lever type collet closer Indexing 8-station turret with pre-loaded ball bearing head and cross feeding with adjustable stations. Indexing one station at a time and locking is via convenient hand lever. 8-station turret drum type carriage stop Welded steel pedestal with storage compartment and collet tray Independent D.C. variable power feeds for turning, facing and boring Built-in coolant system with integral sump and self-draining pan Complete 3/60/220 volt electrics Tool holders for turret: TH-01; TH-02; TH-03 Eight Station Turret By moving the locking lever approximately 90 the precision ground, eight station turret, automatically indexes one space. Return lever to its original position and the turret is rigidity locked ready for the next operation. This automatic indexing feature saves time and can increase production. Eight - Station Stop Drum The longitudinal movement of the carriage is controlled by the stop drum. There are eight adjustable stops for positioning the eight - station turret. Additional clearance in the bed has been provided so the operator can rapidly index the stop drum to desired position. Independent Electronic Variable Feeds The independent electric variable feed for carriage and cross slide provides complete freedom of operation. The rate of feed can be changed instantly at any time, even when the tool is cutting without wasting valuable production time stopping the machine to shift gears as is the case with slow conventional lathes. Speed Control Levers Spindle rotation and speed range can quickly be selected by moving the control levers shown in the illustration to the proper position. Placing the forward reverse lever at the center position automatically actuates the solenoid operated spindle brake. 5

8 Optional Accessories Quick - Acting Recessing Tool the recessing tool is used to perform recessing work, back facing or chamfering operations in the same setting of the work as other turret opertations. The 0.22 (5.5 mm) travel either side of center is governed by adjustable stops. The recessing tool head takes the 0.63 (16 mm) diameter shank tool holders. Carriage Length Indicator (Indicator not included) The carriage length indicator permits full carriage travel allowing for close to spindle machining. The carriage length indicator is a needed accessory when producing parts to exact shoulder lengths or when facing too close tolerances. The fully jeweled dial indicator reads directly in 0.01 mm increments with a range of 0.39 (10 mm). The long rod allows the indicator to be extended to a distance of 6.5 (165 mm) Indicator Carriage Stop (Micrometer and indicator not included) The Micrometer carriage stop is a useful accessory when producing parts with exact shoulder lengths or when facing to close tolerences. The indicator reads in 0.01mm increments. the micrometer reads in 0.01 mm increments. Steady Rest Long cylindrical work held between centers requires a steady rest to prevent such work from springing away from a cutting tool. A steady rest is also used when there are machining operations to be performed on the end of work which prohibits the use of tailstock center. The steady rest has a maximum capacity of 2.99 (76mm) 7

9 Optional Accessories Follow Rest When you have work that is small in diameter in relation to length, it may spring away from the cutting tool. In such cases, the follow rest can be applied to the carriage and will assure you of accurate work. Six Station Bed Turret The turret tool holder diameter 0.63 (16 mm) slide travel 0.35 (9 mm) Taper Turning Attachment The turning or boring of precision tapers is readily accomplished by the use of a taper turning attachment. the taper turning attacment is based on the sine bar principle swiveling the guide bar from one end. Graduations for setting guide bar are in degrees. The taper turning attachment mounts directly on the back of the lathe bed and is adjustable along the bed to suit the work. Chip and Coolant Shield This transparent plastic chip and coolant shield is optional equipment. The hinged section is adjustable to left or right to suit work requirements. Extended sections offer additional splash prevention. 8
