Delivery, interdepartmental transport, assembly and commissioning Notes on transport, installation, commissioning Improper transport, installation and commissioning is liable to accidents and can cause damage or malfunctions to the machine for which we do not assume any liability or guarantee. Transport the scope of delivery secured against shifting or tilting with a sufficiently dimen- sioned industrial truck or a crane to the installation site.
Unpacking the machine INFORMATION The milling machine is delivered pre-assembled. It is delivered in a transport box. After the unpacking and the transportation to the installation site it is necessary to mount and assemble the individual components of the milling machine. Install the machine close to its final position before unpacking.
Load attachment point in unpacked condition WARNING! Before lifting the milling machine, check that all clamping screws of the milling table and the spindle head are tightened. The milling machine is lifted by both eyebolts using a fork-lift truck or crane. ...
INFORMATION In order to attain good functionality and a high processing accuracy as well as a long service life of the machine, the place of installation should fulfil certain criteria. Please observe the following points: The device must only be installed and operated in a dry and well-ventilated place. ...
Only use tool holders in the intended admissible speed range. Tool holders may only be modified in compliance with the recommendation of OPTIMUM or of the manufacturer of the clamping devices. ATTENTION! Before commissioning the machine, all bolts, fastenings and protections must be...
This process is not reversible, i.e. the binding agent can- not be re-softened. The company Optimum Maschinen Germany GmbH does not assume any guarantee for sub- sequent damages due to unsuitable cooling lubricants.
3.12 Electrical connection CAUTION! Lay the connection cable to the electrical cabinet and the cable of the coded connector from the machine to the electrical cabinet in such a way as to prevent a trip hazard. WARNING! The three-phase electrical connection may only be performed by an electrician or under the guidance and supervision of an electrician.
3.12.1 Regulated drives in connection with residual current devices Speed-controlled drives are one of the standard equipment in machine and plant construction and perform various tasks. Compared to a simple motor, the electronic rectifiers or converters require some special features for the necessary safety measures for electrical safety. Depend- ing on the application, the use of a fault current protection device, differential current monitor- ing or insulation monitoring can make more sense.
To avoid an operating fault, you need an AC/DC-sensitive ELCB. Be absolutely sure which leakage current security is necessary for dangerous body currents, as regulated in DIN VDE 0100 part 410, at your mains connection. 3.12.4 When the ELCB triggers Pulse current - sensitive ELCB type A ...
4.1.2 Control panel spindle gear WARNING! Never grip the tool to rotate the spindle as this may engage a gear setting. Img.4-2: Speed table ATTENTION! Only change speeds and gear settings when the machine is at a stop. Use the torque button to facilitate the engaging of gear settings. Optionally, the handwheel on the rear of the spindle can be used to facilitate engagement in gear positions.
4.1.3 Direct run Use the torque button to facilitate the engaging of gear settings. The spindle begins to rotate providing the torque button is pressed. For this, the spindle guard must be closed. Press the torque button only briefly. Optionally, the handwheel on the rear of the spindle can be used to facilitate engagement in gear positions.
Operational modes of the machine Manual operation with the hand wheels on the cross table. - The protective housing should be closed, the spindle guard must be set to high. The pro- tective housing must be closed if the cooling equipment is used. Operation with the automatic table feed.
The optimum cutting speed mainly depends on the material and on the material of the tool. Hig- her speeds are possible with tools (mills) made from hard metal or cutting ceramics than with tools made from high-alloy high speed steel (HSS).

4.11 Activate / deactivate automatic table feed The feed drives consist of a universal helical gear and an inverter motor in each axis. The feed force is 1600 N with a continuously adjustable feed from 0.05 metres per minute to 0.45 metres per minute.
4.12 Turning the milling head vertically Loosen clamping screws and Clamping bolts rotate milling head to 90°. Re-tighten clamping bolts. Scale angle of rota- tion 4.12.1 Aligning the milling head INFORMATION The milling head should be aligned after resetting to the initial position with a dial indicator so that holes can be produced with the spindle sleeve at a right angle.
4.13 Fastening horizontal table CAUTION! When milling with the vertical milling table - horizontal table is dismantled, chip and spray guard is dismantled - e.g. when mounting a dividing apparatus on the vertical table -, the machine operator must take additional precautions to ensure safe operation. We recommend mounting e.g.
4.14 Clamping the tool WARNING! When milling operations are performed the cone seat must always be fixed to the draw- in rod. All cone connections with the taper bore of the work spindle without using the draw-in rod is not allowed for milling operations. The cone connection should be released by the lateral pressure.
4.16 Optional compressed air tool clamp of the vertical spindle The pneumatic tool clamp can only be used when the spindle guard is open. ATTENTION! Loosening the tool when the spindle is running out can lead to damage. Wait until the spindle stops completely before pressing the tool release button.

The milling machine has been painted with varnish. This fact must be taken into account when selecting your cooling lubricant. Optimum Maschinen Germany GmbH does not accept any liability for subsequent damages due to unsuitable cooling lubricants. The flashpoint of the emulsion must be higher than 140°C.
The products must comply with the provisions of the current statutory regulations and the employers' liability insurance association. Request documentation for the products such as the product description VKIS and EC safety data sheet from the cooling lubricants manufacturer. The EC safety data sheet gives you information about the water hazard class.
If the repairs are carried out by qualified technical personnel, they must follow the indications given in these operating instructions. Optimum Maschinen Germany GmbH accepts no liability nor does it guarantee against damage and operating malfunctions resulting from failure to observe these operating instructions.
Inspection and maintenance The type and level of wear depends to a large extent on the individual usage and operating conditions. Any indicated intervals therefore are only valid for the corresponding approved con- ditions. Technical specification on page 20 Check Interval Where?
