Installation and assembly 3.6.1 Requirements regarding the installation site To achieve sufficient security against falls by slipping, the accessible area must be provided in the machining area of the machine with a slip resistance. The anti-slip mat and / or the anti-slip flooring must be at least according German BGR 181 R11.
3.7.1 Lubrication The lubrication and initial greasing of your new lathe consists of checking the oil levels through the headstock, apron and feed box oil sight glasses. The oil tanks must be filled to half way up the sight glass. Once these operations have been car- ried out, the machine can be started up.
Risk from using improper workpiece clamping materials or operating the machine at an inadmissible speed. Only use the tool clamping devices (e.g. lathe chuck) that were delivered with the machine or those offered by OPTIMUM as optional equipment.

CAUTION! The emergency stop button may only be activated in an emergency. You should not use the EMERGENCY STOP button to stop the machine during normal operation. Resetting an emergency stop condition Set the rotational direction control lever to the neutral position. ...
4.9.2 Position change of the V-belt package Opening the protective cover Turn the machine off at the main switch. Disassemble two thumbscrews and open the protective cover of change gear. Loosen the two fastening screws, the one on the right and the other on the left of the engine.
4.10 Turning direction With the control lever the rotation of lathe is switched. The lathe can only be switched on, when the lathe chuck protection is closed. Turn the control lever down if you want the turning direction to be anti-clockwise. ...
4.12 Tool holder Clamp the lathe tool into the tool holder. The lathe tool needs to be clamped as short and tight as possible when turning in order to be able to absorb the cutting force during the chip formation well and reliably. Img.4-4: Tool holder Adjust the height of the tool.
4.13 Lathe spindle fixture DIN ISO 702-2 Nr. 4 (Camlock) WARNING! Do not clamp any workpieces that exceed the permitted chucking capacity of the lathe chuck. The clamping force of the chuck is too low if its capacity is being exceeded. The clamping jaws may loosen.
4.13.1 Fasten workpiece holder Fasten the workpiece holder by turning the clamping bolts clockwise. The right clamp position is reached when the reference marker at the clamp holder are between the two marks at the lead spindle seat. The tightening torque must be approximately 80 Nm, otherwise the rotational accuracy of the lathe chuck is not present.
4.13.3 Speed information, maintenance recommendations, reference speed in accordance with DIN 6386 The reference speed is the number of rotations, at which the mathematical centrifugal force with the corresponding jaw design correlates with the greatest tensioning force when the machine is at a standstill. The reference speed applies for jaws mounted inside in tiers, whereby they must not protrude past the outer diameter of the chuck.
4.13.5 Lathe chuck maintenance A crucial prerequisite for fault-free functionality of a lathe chuck is regular and thorough lubrica- tion of the sliding surfaces. This prevents the reduction of tensioning force and premature wear and tear. Always observe the manufacturer's maintenance instructions when using replacement lathe chucks.
4.13.7 Mounting workpiece holder Centering point Clean the taper bore of the lathe spindle holding fixture. Clean the morse taper and the taper of the cen- tring point. Press the centring point and the reduction sleeve into the taper bore of the lathe spindle holding fix- ture.
4.15 Bed insert Remove the bed insert if the diameter of the workpiece turned is larger. By removing the Fixing screws bed insert, the rotational diameter can be increased. Dowel pins First detach the fastening screws and then pull out the alignment pins. ...
4.16 Setting the feed Example: Feed 0.07 mm / spindle revolution With the same settings you will achieve a longitu- dinal feed of 0.261mm / spindle revolution. a = 60 teeth 120 teeth 60 teeth ATTENTION! The change wheels have to be mounted according to the layout of the feed table in order to achieve the indicated feed rate.
4.17 Adjusting threads Example: Thread pitch 1.75 mm per revolution a = 56 teeth 120 teeth b = 60 teeth Set selection lever to A - C - 4 - R Example: Inch thread 120 teeth 127 teeth TH3309 | TH3309D Translation of original instruction Version 1.1.0 - 2020-08-06...
4.17.2 Exchange, change of position of the change gears The change gears for the feed are mounted to a quadrant respectively directly on the lead screw and feed gear. Always disconnect the main plug of the lathe and secure the main switch by a padlock, against unauthorized or accidental acti- vation.
4.18 Tailstock The tailstock sleeve is used to hold the tools (bits, centres, etc.) Clamp the required tool in the tailstock sleeve. Use the scale on the sleeve to re-adjust and / or adjust the tool. Clamp the sleeve with the clamping lever. Use the hand wheel to move the sleeve back and forth.
4.19 General operating instructions 4.19.1 Longitudinal turning In the straight turning operation, the tool feeds parallel to the axis of rotation of the workpiece. The feed can be either manual - by turning the handwheel on the lathe saddle or the top slide - or by activating the automatic feed.
4.19.4 Turning between centres CAUTION! When clamping workpieces between the lathe centres while using a lathe dog, the existing lathe chuck shield must be replaced with a circular lathe chuck shield. Workpieces that require a high concentricity precision are machined between the centres. For holding purposes, a centre hole is drilled into both plain machined faces of the workpiece.
Consider this fact when selecting your cool- ing 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.
Page 55
The selection of cooling lubricants and slideway oils, lubricating oils or greases as well as their care are being determined by the machine operator or operating company. Therefore, Optimum Maschinen Germany GmbH cannot be held liable for machine damages caused by unsuitable coolants and lubricants as well as by inadequate maintenance and servic- ing of the coolant.
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.
