The PCS BHB is the ultimate profile cutting machine. No other machine on the market offers a solution with as much emphasis on brute force, rigidity and capability. With options ranging from high-speed drilling, tapping, boring, countersinking, beveling, gas and plasma cutting, pipe cutting, ink jet printing, pin marking, or any combination, all with precision motion control.
Machine Design
The machine carriage is an all welded construction with a wholly fabricated beam that utilizes several design characteristics used within the aerospace industry. Supporting the fabricated beam are ultra solid modular side supports. The drilling process is driven by a 60HP Digital AC Servo motor. Connected to the motor is a BT50 or Cat50 spindle that can handle up to 1395 FT/LB (1890NM) of torque. The drill assembly is supported on linear rails with the vertical motion also driven by a Digital AC Servo Motor. To ensure that the steel plate remains stationery the BHB utilizes a fabricated clamping mechanism which is controlled by an additional Digital AC Servo motor capable of producing up to 3.3 Ton (3.0 tonnes) of force. To reduce machine downtime the BHB utilizes as standard a 24 Pot Automatic Tool Changer which has a tool change time of 2.5 seconds.
To ensure ultra smooth operation the side supports run on extra reinforced fabricated rails with a machined billet running surface and vertically adjustable base plates which are adjusted on site to provide a ridged and finely tweaked level running surface. With extra powerful state of the art Digital AC dual drive system and integrated active rail cleaning system, the PCS BHB will perform to the strictest of tolerances for decades to come in a highly demanding industrial environment. As several clients have already confirmed, if you are looking to drastically reduce the lead time on projects that require high speed drilling, cutting and plate edge preparation then the BHB will provide results that cannot be matched. Furthermore one client has stated that, “the PCS BHB has drastically reduced job completion times, from 8 hours to only 2 hours.”

Machine MassLarge mass is crucial for high speed drilling. Plate profile machines such as the BHB are dynamic and process plate on a hollow cutting/drilling bed. This leads to what can be severe vibrations when drilling/machining. Therefore, the machine needs as much mass behind it in to ensure that the kinetic energy is transferred only to the right places. Fewer vibrations means faster drilling and better tool life! |
Solid Cutting/Drilling TableThe cutting/drilling table is as important as the machine on top of it. Our cutting/drilling tables are built just as tough as the BHB machine. They have several supports connecting the steel plate directly to the concrete floor. This is to minimize vibrations that are common with high speed drilling on profile machines. |
Ease of OperationOur state-of-the-art drilling HMI integrates seamlessly with the tried and trusted Burny 10 CNC. With pre-loaded drilling libraries, the operator doesn’t require an in depth knowledge of drilling speeds and feeds. The HMI was designed to be extremely user friendly and as such can be mastered in literally seconds. |
ProductivityHigh productivity is a crucial factor when investing in capital equipment such as profile cutting machines. The BHB achieves the highest productivity in its class thanks to its mass and a solid cutting/drilling table. The fastest drilling times and longest tool life are the key factors in achieving such high productivity. |
Coolant SystemWe offer a dual minimum quantity lubricant and flood coolant system, unique only to BHB series cutting and drilling machines. Either coolant method (MQL or flood) can be selected for each individual tool in the on-board tool library. All BHB series machines using a UNIST MQL system utilize a specially made Dueblin rotary coupling to deliver the minimum quantity lubricant (MQL). Because the atomization point is as close to the cutting surface as possible, machines utilizing this technology are able to achieve the best possible results with MQL. This equates to class leading drilling performance and tool life which is currently unmatched by any other machine on the market. |
