infeed is performed with the handwheel of the top slide. The depth of cut is advanced with the handwheel of the cross slide. Gauge Stop measure 100 mm Measuring direction Advance of depth of cut Fig.4-10: Cone setting with stop measure 3.
The calculated value "Vr" is the offset measure of the tailstock. The offset is monitored with the gauge (also the return travel). For this type of cone machining the lowest speed is used ! Annotation: In order to check the position of the tailstock axis to the rotation axis, a shaft with two cente- ringsis clamped between the points.
Speed: n (rpm) Workpiece diameter: d (mm) For lathes without continuously adjustable drive (flat belt drive, speed gear) the nearest speed is being selected. Cutting depth: In order to achieve a good chipping, the results of the depth of cut divided by the feed shall re- sult in a figure between 4 and 10.

For larger pitches the alternately flank infeed is selected. The top slide is from the 2nd passage in each case 0.05 - 0.10 mm adjusted alternately to the left and right. The last two passes are performed without lateral offset. When the depth of thread is achieved, two passes are performed without infeed.
4.19 General operating instructions 4.19.1 Clamping long workpieces through the hollow shaft of the spindle CAUTION! Long rotating parts that protrude from the hollow shaft of the spindle must be secured by the operator using suitable covers. A cover can be a sleeve that is mounted on the headstock that, as a permanent safety device, completely covers the protruding workpiece.
4.21.1 Cross-adjustment of the tailstock The cross-adjustment of the tailstock is used for turning long, thin bodies. Loosen the adjusting screws in the front and in the rear of the tailstock. Scale By alternately loosening and tightening the two (front and rear) adjusting screws, the tailstock is moved out of the central position.
4.22.2 Face turning and recessing In the facing operation, the tool feeds per- pendicular to the axis of rotation of the workpiece. Feed is done manually, using the cross-slide hand wheel. The infeed for cut depth is made with the top slide or lathe saddle.
4.22.4 Thread cutting The thread cutting process requires that the operator has a good knowledge of turning and suf- ficient experience. INFORMATION Due to a safety mechanism, it is not possible to use the longitudinal feed via the lead screw and ...
Consider this fact when selecting your coo- ling lubricant. The company Optimum Maschinen Germany GmbH does not assume any guarantee for sub- sequent damages due to unsuitable cooling lubricants. The flashpoint of the emulsion must be higher than 140°C.
VC_GB.fm Cutting speeds Selecting the cutting speed The variety of factors makes it impossible to present universal indications about the "correct“ cutting speed. Tables with reference values about cutting speeds to be set must be evaluated with utmost caution since they only apply for very particular cases. The refe- rence values without cooling (no best values) which are indicated in AWF documents are highly recommended.
