Manifold drilling, Hairpin bender, Straightening and cutting, Return bender, Automatic brazing, Tube cutoff-bending & Coil bender

The Manifold drilling (MDM) is the perfect solution to drill manifolds in copper and its alloys, aluminum, steel, stainless steel, etc. with max. diameter of 220mm. It may have or not the tools warehouse and may operate both in drilling and milling mode. It is then in a position to perform drills out of the axis. It is possible to program the number of holes to execute for each row, the number of rows and the radial position in degrees of each row. It is possible to change the tooling and repeat the cycle, or to execute flaring or other operations. It is also possible to program different cutting speeds in each function where different tooling is installed. The manifolds are held in position by pneumatic clamps and supports. For the copper tubes, it is possible to supply (on demand) a special tool that can produce extruded collars, in order to increase the contact surface between the manifold and the nipple during the brazing process. A numeric control manages the machines' operation in all their NC and PLC (Programmable Logic) functions. Upon request it is available a manifold drilling machine for punching MPM, an ideal machine for the production of medium and big series of manifolds in copper and its alloys, aluminum and steel. It has great flexibility, very simple to program and it allows to perform drills of max. 0.625in/16mm on manifolds with diameter up to 3.54in/90mm and thickness up to 0.2in/5 mm.

Base models:

• MDM: without tools warehouse
• MDM-SS: with warehouse up to 4 tools

Each base model could be equipped with:

• 3 NC axes plus mandrel, without transversal translation of drilling head
• 4 NC axes plus mandrel, with transversal translation of drilling head (on demand)

Specifications

• Y axis control for holes out of centreline of manifold (on demand)

Axes managed by NC

Safety
The manifold  drilling is equipped with a safety guard and thus intrinsically safe; the opening of the guard places automatically the machine under safety conditions.
