special brushes, the unit can also be used

to obtain original types of sheet metal surface

To ensure separation of metal particles and

recycling of the cooling liquid, Topmetal uses

a fabric/non-fabric fi lter with an automatic

reel unwinding system. Alternative types of

fi lters are available for machines intended for

more intensive uses.

Topmetal contact rollers are available with

a diameter of 250 mm or 320 mm. The

latter, thanks to the larger contact surface

with the workpiece being processed and

greater ability to absorb any defects on the

abrasive belt joint, are specifi cally indicated

for all applications requiring very high quality

fi nishes.
Topmetal cleaning

Topmetal cleaning

Topmetal is fitted with a unit in the outfeed

area to clean and pre-dry the workpieces.

The device consists of a set of nozzles for

cleaning using an emulsion, a twin pair

of rubber-coated counteracting motorized

rollers and an air blade system powered by

an electroventilator positioned on the top of

the machine.

For specifi c drying requirements, the system

can be fi tted with resistances to heat theair

Metal System

DRY DEBURRING FINISHING MACHINE FOR METALS represents a heavy-duty solution dedicated to the medium and large end user, as well as dedicated contractors, who are required to combine productivity, reliability and flexibility due to the ever changing work orders.

In a single pass the machine is able to:

eliminate any burr produced by the cutting process
efficiently remove sharp edges all while creating a radius
deburr and radius holes of small dimensions
efficiently removes oxide generated while cutting, whether from the outer perimeter of the piece or the inner circumference of the hole.

Main equipment

operating unit with large diameter contact roller
planetary unit equipped with rotating disc brushes
oscillating unit equipped with rotating disc brushes
vacuum table for processing small pieces, with in-built electric fan located in the machine frame
working table at fixed height from floor for either stand alone or to be inserted in through-feed automatic lines
machine controlled by “Hydra PC” with 17” touch-screen
Advantages
- Excellent results for deburring, oxide removal and producing non-directional scratch thanks to the exclusive planetary unit which uses a gear box transmission that allows for independent speed rotation control of the brush discs as well as the planetary main discs.
- Quick change-over time for the replacement of the brush discs thanks to the quick disconnect spindle shaft system that allows for a fast and easy set-up of the machine for any type of application while allowing for the maximum safety due to the locking system.
- Extremely reliable and noiseless motor power transmission, even during the most extreme processing conditions, thanks to the multi-grooved Poli-V belts along with the self-tensioning belt device.

MODULAR STRUCTURES FOR MAXIMUM CUSTOMIZATION

Metal System is available with base structures capable of holding up to 10 working units in order to perfectly perform any deburring or graining application.

The modular structure of the machine along with the newly designed working units (each incorporating its own electronic and pneumatic functions) allows for maximum fl exibility within the machine in order to meet the changing needs of production. In fact any single working unit can be replaced quickly and economically (or their placement inside the machine can simply be changed thus changing the composition of the machine).
Innovative

The innovative DP Planetary unit was developed by DMC in response to the demand to the more complex needs of deburring and rounding of work piece edges. All of the motor transmissions in the unit are driven by sprockets sealed and constantly lubricated (NO DRIVE BELTS ARE USED!), thus ensuring the unit is capable of working with

The multi-directional action is what makes the DP unit unique and, especially, efficient.

The three movements of the unit (rotation of the abrasive brushes, counter-rotation of the brush holder discs and high speeds or when working 3 working shifts per day.

These exclusive construction features of the unit guarantee high levels of reliability as well as minimal noise levels during operation. Lateral movement of the head) are driven by independent motors, all controlled by inverters making it possible for the operator to choose the most suitable combination of speeds according to the specific type of application.

Eurometal is available with a wide range of different contact rollers

to ensure that they can handle any deburring or satinising task.

The rollers available have the following features:

• Diameters from 160 to 250 mm

• Rollers coated with oilproof and heat-resistant rubber with

hardness ratings from 85 to 45 sh

• Pneumatic ON/OFF to control work positioning

• Electronic grit-set, for decimal adjustment of the roller work

height directly from the control panel (optional)

La struttura di supporto dei dischi rotanti, anziché

soluzione permette ai dischi spazzola di essere
