The equipment has selectable advance grinding time functionality by user from 50 to 400 seconds. Optimum grinding time per end of all type specimens is 90 to 120 seconds. The specimens fixed to the any cradle are abraded by the grinding wheel which has bidirectional radial displacement ability. The safe and ergonomic design provides easy access to the water inlet and outlet. Specimen cradles can easily be installed without the need for any assembly.

Mobility of the machine is achieved with the help of the integral wheels, and all components of the system can be safely accessed for easy maintenance. The parts exposed to water are made of stainless steel to resist corrosion. In Table 1 dimensions and weight of the device can be seen.

Table 1: Dimensions and Weight of UTC-1060

UTEST UTC-1060 Automatic Grinding Machine consists of fixing clamp, grinding wheel, cradle, water gun. Locations of these units can be found in the following section.

There are 3 optical sensors in the cabin adjusts the initial position of the cradle and grinding wheel (Figure 3).

There are small lights on them for stating that they are in operation. The one not indicated with red arrow get rarely activated as the grinding head normally run between sensors indicated with red arrows. This sensor is located for safety purpose that if rotating head does not stop at the middle sensor, this sensor catches the rotating head. The light of the middle sensor should be lit when the device is ready for the test after sample placement (Figure 4). The bolt and the related middle sensor tips should be aligned before starting a test.

Also, there is another sensor to adjust the vertical position of the grinding wheel (see Figure 6) which is reset position. If the grinding wheel is not in vertical position this sensor activates the grinding wheel motor and motor align the grinding wheel in vertical position when Reset option on the control panel is used.

The control panel of the device consists of timer unit, run and alarm lights and start-stop-reset-emergency stop buttons.

Timer: The timer controls the duration of the full cycle. The grinding time is determined for each sample according to material hardness and cylinder diameter. The timer is set in seconds only.

For example, 120 seconds= 2 minutes. The device is set to 100 secs from factory. The ± buttons located above and below the numbers determine the units, tens, hundreds and thousands of seconds, up to a maximum of 9,999.

Green Run Light: It is connected with start button. It blinks during reset process.

Red Alarm Light: It comes on when panel cover sensor is faulty or panel cover is not placed, invertor failure, motor failure and when emergency stop button is pressed.

Start – Stop Buttons: They are used to start and stop the test.

Reset Button: It is used to reset the counter number. The reset button is used after one of the alarm situations occur on device and device is stopped before test is completed automatically. It does not need to be pressed during regular test intervals, as the device automatically moves back its current test start initial position after the last test ends.

Emergency Stop Button: It is used to stop the whole device in case of emergency.

Table 2: UTC-1060 Electrical Connection Properties

Main electricity line must be free from instabilities and repetitive power cuts for both the extended life of the device and the continuity of testing. Therefore, make sure that the mains supply is well grounded. If the power cuts are frequent or the grounding is not well enough, the use of an uninterruptible power supply (UPS) is recommended.

Make sure that the device is placed in a clean and dry surrounding. Direct contact of the device with the sunlight should be avoided. A conditioned room for example, will comply the above conditions and will result in best operational performance and measurement results. Device should be well accessible from the front and the sides for connections, testing and maintenance.

In order to prevent inaccurate test results, the ground should be rigid enough to minimize vibrations or shocks. If there are any other testing equipment or a source that creates vibrations on the floor, UTC-1060 should be placed maximum possible distance to that source. Surface of the ground should be horizontal and smooth enough so that the horizontal and vertical alignment of the device are not shifted.

NOTE: If remote assistance will be required from the UTEST Technical Service Department, the room should have an internet access.

Place the device somewhere near the electricity and main water supplies. After placing the device, connect the mains water to the water inlet on the

right side of the device with the help of a hose because the grinding wheel is done with water to prevent excessive wear of grinding wheel and excessive dust formation.

The device should be installed close to a drain in order for the wastewater to flow without accumulation. If there is no such possibility, wastewater can be deposited.

1. Read the requirements of the standard to be applied before starting the test and prepare all the materials needed to perform the test.
2. Select the appropriate cradle to grind the samples and place it (see Figure 9).

3. Place the samples on the cradle. When doing this, make sure that there is no a distance between the samples and the grinding wheel, the samples should contact with the grinding wheel. Then pull the

distance arrangment clamps adjust the fixing mechasim to correct height and secure it.

NOTE: If the diameter of the sample is between 38 mm and 100 mm, a 4-channel cradle should be used to grind these samples. If the diameter of the samples to be grinded is more

than 100 mm, a 2-channel cradle should be used.

4. By turning fixing clamp secure the specimens. Be sure that specimens firmly fixed to its positions.

5. Plug the power cord. Then turn on the power switch by pressing the on / off switch located at the back side of the device.

6. Set the run time of the grinding operation from the timer. To do this press the Left arrow key to switch the digits. Set each digit by using Up key. Then press MODE key.

7. Close the cover and press RESET button on the control panel in order to bring the device at start position.
8. Open the water inlet valve and press “START” button (see Figure 13). When the “START” button is pressed, the green light will light on the RUN button. This indicates that the device is working.

WARNING: Never attempt to run the device without supplying water. Otherwise, the warranty procedure will not applicable for

some related damage.

NOTE: The device should be installed close to a drain in order for the wastewater to flow without accumulation. If there is no such possibility, wastewater can be deposited into a trough.

9. Rinse the front side of the device with pressurized water using water gun located at the right side of the device and if possible should be dried by using a compressor.

WARNING: It is important to care that the unit must be switched off and the main cable must be removed before starting any

maintenance for user’s safety.

All safety devices must be functional at all times. Damaged protective covers must be replaced as soon as possible. When safety components are replaced, the protective devices are to be properly attached and tested.

We recommend that the device is cleaned of any particles and dust from the scattered specimen after the test with a damp cloth and brush to avoid incrustations which could damage the paint work.

As with all electrical equipment, machine must be used correctly and maintenance and examination must be performed at regular periods. Such precautions will guarantee the safe and sufficient functioning of the equipment.

Maintenance to the equipment is responsibility of the purchaser and must be performed as stated by this chapter. Failing to perform the recommended maintenance actions or maintenance performed by unauthorized people can void the warranty.

The section between the cradles should be lubricated every month. Please apply little amount of oil or light grease by using a small brush.

After the end of every test day, the fore section of the machine should be rinsed with pressurized water thoroughly and if possible, should be dried by using a compressor.

Every 3 months, the motor bearings and swing mechanism arm should be greased via grease nipples (see Figure 17 and Figure 18).
