Automatic cut-off machine with drilling unit

Horizon Brown 1500 AP is the Pedrazzoli branded development in the field of automatic cut-off machines designed to cut set lengths from steel bars or other materials. The machine – which can be supplied with a drilling unit – is suitable for 90° or inclined cutting of solid bars, tubes and sections. On request the company can also supply the machine with a bundle feeder and a scrap remover-selector. The drilling unit can be supplied for automatic cycle operation on steel, metallic alloy, aluminium and all other materials the machine can cut. This work unit can bore holes on tubular sections and bars up to a maximum diameter of 142mm and thickness of 5mm. The wide drilling diameter range is from a minimum of 3mm up to 20mm.

Drilling tool movement is horizontally controlled by a controlled axis with a 200mm total stroke, while vertical cams keep check on travel stop and start positions as well as on the two speeds (slow/fast). The double slow-fast command capability can be used on tubular sections, which allows drilling of the first face with a slow advancing speed, progression onto the second face with a greater speed and final drilling under a slow speed. Tool rotation can be undertaken with 4 or 8 gears with manual gearbox. Alternatively, it can be supplied with an inverter for a speed range from 300 to 2,000rpm. During the work-cycle tool lubrication is fulfilled by coolant liquid or micro-mist lubrication (optional). The drilling chip

removal is carried out by means of an optional cutting table cleaner. IMS software, developed by Pedrazzoli’s R&D department, ensures simple and quick work cycle programming according to a clear setting of parameters. A set of icons also allows this software to plan the drilling cycle by introducing the most important drilling tool control parameters.
