-.Description:

Transmission belt skiving, with motor-driven abrasive roller and manual table advance with inclination adjustment for various bevelling angles. Abrasive roller height adjustment using an eccentric shaft.

-.Connecting to the mains supply:

The machine should be connected to a mono-phase 230V mains electricity supply, depending on the voltage stated on the technical specifications plate, together with the corresponding earth connection.

-.Technical Characteristics:

Dimensions 650 x 640 x 570mm.(L x A x H) Weight 65Kg Roller width 385 mm. Bevel travel 140 mm. Roller diameter 120 mm. Maximum thickness 10mm. Revolutions 300//800 rpm. Bevel angle from 0º to 3.5º Voltage 1 x 230V. Power 1.5 kW.




-.Using instructions:

Fit the adhesive tape over the white nylon plate in the working zone, just as shown in the figure. This operation is essential to obtaining a good finish since it will prevent stretching and breaking during the process.

The belt should be passed under the retaining bar up to the edge of the table, adhering the end to be bevelled on the adhesive tape just at the table end as shown in the following photo.




Fix the belt in place using the bar by means of the knobs (A) always attempting to maintain parallelism with the table, in other words, performing this operation on both sides at the same time and in the same proportion.

We then adjust the bevelling angle as given in the values table releasing the milled knob towards the outside of the machine as shown in the diagram and turning it to the required point and then locking it again.



TÍTULO DEL DOCUMENTO The abrasion roller should then be raised, using control

(B ), turning it anticlockwise in order to perform the bevelling operation slowly to avoid overheating the material and jerking the belt.

We assume that the roller is raised when it there is no contact between the roller and the belt when the table is advanced towards the interior.



TÍTULO DEL DOCUMENTO NOTE: raising control (B) operates an endless crown mechanism which, in turn, rotates the eccentric supports. This means that if we exceed the number of turns in either of the two directions, we will produce a change in direction, even though the control continues to be turned in the same direction. Starting-up the motor by pressing the green button on the electrical control panel.

The bevelling operation should be performed so that, at the same time, the table is moved backwards and forwards, the abrasion roller is lowered, but in a moderate fashion. The right hand is only used to operate the advance lever (C), with the left hand operating the raising control (B).




We consider that the operation has been completed when there is no more abrasion produced on the belt and the abrasion roller is resting on the height stop.



TÍTULO DEL DOCUMENTO -.Changing and adjustment the abrasive tape:

We also recommend that the polycarbonate protection is removed to provide more working space and to avoid any damage to this protection.

When changing the abrasive belt, the machine must be disconnected from the mains electricity supply in order to guarantee a safe working environment. Once this has been done, the motor head should be fully opened protection belt T-10




The old tape should be removed by pulling on it at one end and rotating the roller until it is completely free. The entire roller surface should be cleaned with alcohol or a similar product in order to guarantee good adherence of the new belt and a uniform level without any thickening. Cutting the abrasive tape.



TÍTULO DEL DOCUMENTO When changing the abrasive belt, the machine must be disconnected from the mains electricity supply in order to guarantee a safe working environment. Once this has been done, the motor head should be fully opened roller cover protection

Cutting the abrasive tape.



TÍTULO DEL DOCUMENTO Levelling the table with respect to the abrasion roller. This operation will only be necessary in a situation of misadjustment due to possible knocks or vibrations during transport. Levelling the table requires the loosening of the height stops

Adjust setting of the inclination control to the 0 position.




-.Warnings:

- The machine should always be connected to the mains electricity supply via

thermal-magnetic and differential breakers, and protected by an earth connection.

- Under no circumstances should any work be carried out without the belt and

roller protections.

- The suction nozzle should be connected to prevent the possibility of inhaling toxic particles.

- Remove the mains electricity supply plug from the socket before carrying out

any adjustment or similar operation.

- Possible problems and solutions.

The motor will not start up. Check that the Emergency Off button has not been operated or verify that mains electricity is available. Incorrect bevel operation. Check the abrasive tape condition or level the table.
