4.1.Instructions for unpacking and setting up

Take special care when lifting the load: The load may not be centered! To do this, use a forklift with blades long enough to support the machine, taking into account the width and depth of the machine for the calculation of the weights to lift.

Once the packaging has been opened, remove the fixing stops from the feet of the machine

To remove the machine from the packaging, use a forklift only, with blades long enough to properly support it.

Be sure to lift the machine by placing the forklift blades in the two holes located on each side of the machine for this purpose.

The blades must remain open to the total that the machine's hole allows, in order to have better stability.


Once the machine is located in its final location, you can now remove the protective film and other protections for components, which fixes and prevents the carriage from moving.


5.1.Machine placement

Before any work we must make sure that the machine is well aligned and does not oscillate at any of its ends, in which case it must be wedged to avoid movements. For its correct level it is necessary to use a spirit level. This check must be carried out both longitudinally and transversally.

Poorly leveling the machine can cause unwanted vibrations and premature wear of the linear guides.


WARNING: The machine must not be used under any circumstances by unqualified or unauthorized personnel.

5.2.Electrical connection



Remember: before connecting the machine, remove any protection that the machine may have to protect the components during transport.

The ELITE model CU mini 1200 grinding machine must be strictly connected to the voltage indicated in the machine order and on the machine itself. The connection to a voltage other than that indicated may cause a breakdown in the machine and represents a risk for people who use the machine.

This installation must be carried out by qualified technical personnel and checked with a voltage meter before turning on the machine.

It is absolutely essential that the cross-section of the connection cable is as required, that the machine has a dedicated outlet and is protected against overloads and shunts, and that it is as close as possible to the electrical outlet.

The electrical connection terminals have a red tape to facilitate correct connection.


ELITE does not assume any responsibility in the event of an incorrect electrical installation that may cause a malfunction of the machine and even personal or material damage.

In this section we show you how to operate the ELITE CU mini 1200 in order to work.

NOTE: The data that appears in the different images are by way of example, each type of tool has its recommended data and a skilled operator must know them.

Emergency stop

It's the round red button. In the event that there is a failure in use or a dangerous situation is being created, it allows the immediately disconnection of the machine.

Should not be used unless strictly necessary.

Once used, to use the machine again, you must pull it to return to the initial position, additional referencing and setting up must be needed.

WARNING: Under no circumstances should this control be modified or manipulated, this automatically puts the operator and people around him in danger of serious injury.

Sharpening operation

To start the sharpening process, you must first make sure that the emergency stop button is not activated.

DANGER: never manipulate the buttons on the control panel while changing the abrasive wheel: danger of very serious injuries. It is highly recommended to switch off and disconnect from power mains the machine when working inside the machine.


WARNING: before start to rotate the grinding wheel make sure that it is well attached to the wheel holder where it is located and that NOBODY is manipulating in the area where it rotates. UNDER NO CIRCUMSTANCES SHOULD THE WHEEL BE STARTED WHILE SOMEONE IS HANDLING IT.

6.1.Set up

6.2.Changing the grinding wheel

Necessary tools: Fixed wrench No. 17.

With the machine switched off, remove the hex screw from the bottom of the grinding wheel. Hold the wheel and wheel holder ring throughout so that it does not fall.
Now insert the new grinding wheel.
Reposition the locating ring in the correct position so that the locating pin passes through the locating ring.
Replace the hex bolt and tighten.


7.1. Control Panel

7.2. How to demagnetizer blades and tools

If the blades or tools become magnetized by the magnetic plates, we can use the ELITE demagnetizer to eliminate the remnants (optional accessory).


8.1.Preventive maintenance

The maintenance of the ELITE model CU mini 1200 is very simple but at the same time important.

It consists of the following:

  1. Cleaning of the carriage guides - Daily
  2. Cleaning and greasing the grinding chuck, in case the machine is not used for several days, to prevent oxidation.
  3. Check the level of coolant in the tank, using the coolant recommended by ELITE: SintoCut MIX for steel and ELITE SintoCut PRO MIX for steel + tungsten carbide. The coolant mixture should be made with water at a proportion between 2 and 8% of SintoCut. Being below it can lead to oxidation of mechanical parts and if the level is higher it can be toxic.
  4. Remove the sludge that is deposited both in the work area and in the coolant - Daily.
  5. Grease the carriage slide bearings by means of the greasing nipples - Monthly.
  6. Keeping the machine clean and in good condition will allow for optimal long-term use.

Use the equipment only in dry environments. The temperature must be between 5 and 40ºC. A relative humidity greater than 90%, as well as a saline environment, would cause premature corrosion of the machine.


9.1.Grinding wheels

9.1.1.For heavy grinding on steel blades

We recommend to use ELITE ref. nr. 3522-A2 or 3522-B2. 6A2 Resin ø150x60xø60 mm.

9.2.Coolant agents

9.2.1.Working only with steel and HSS

We recommend to use ELITE SintoCut MIX or equivalent when working only with steel.

9.2.2.Working with steel and carbide

If the machine should work with steel and also with tungsten carbide then it is better to work with SintoCut PRO MIX or equivalent, with is a better choice in order to work with carbide.
