Following its successful launch, SUHNER is presenting the BEA 16 spindle machining unit with an all new drive and control concept.
The objective of this new development was the integration of the latest servo drive and control technology from Bosch Rexroth. Software developed additionally allows the user to program six different basic cycles without prior knowledge of CNC.
By visualizing these six cycles – drilling – combined drilling (drilling and thread cutting with the one tool) – thread cutting – drilling with chip removal – drilling with jump function – undercutting, the unit has become extremely easy to program.

Plus, should the required machining cycle not be found among the standard selections or prove more complex, the unit can be switched to sentence programming.
The BEA 16 machining unit itself is a precision device from the SUHNER spindle machining unit series that has been designed for gruelling continuous use in multiple shift operations. The BEA 16 has a drilling capacity of 16 mm Æ in 450 N/mm2 steel. The max feed path is 140 mm, and the max speed is 500 rpm.
Today, rising production piece numbers and greater workpiece complexity with all-round machining are leading to a renaissance of the so-called special machine. However, today’s special machines are being used no longer as purely single-purpose solutions, but rather for whole part families.

These require different machining cycles, feed speeds, feed paths and rotating speeds, and, of course, must allow fast retooling. And it is these requirements exactly that the BEA 16 will meet to the full.

For best results in the machining of multiple material layers, cutting parameters must be applied for each different material. The new L-MAX, a portable drilling unit from SOMEX (a member of the SUHNER group of companies) can perform all of these functions in automatic mode.
Portable L-MAX drilling unit
Multiple material layers, also referred as Stacks, can be composed of completely different materials, stacked up in layers of, for ex ample: Titanium, Carbon or Aluminum. In order to achieve optimal machining results, each material layer must be programmed with its own cutting parameters- ideally for each layer automatically. The spindle speed and feed rate must be adapted for each material transition to the next.
In the past, aluminum was the primary choice of materials used in the aircraft industry and portable, handheld pneumatic-driven drilling units were used as a common tool in this industry.
The application of these conventional pneumatic drilling units in today’s modern and innovative aircraft industry necessitates extreme compromises. In addition to large air consumption combined with high noise emissions, pneumatic-driven drilling units cannot perform feed and speed variations as required for different stack materials.
Mobile control system IDM
Consequently, only a portable, handheld NC-programmable drill unit is capable to deliver optimal results and high efficiency, since the aircraft industry imposes rigid quality standards including:
– Concentricity / position between holes ≤ 40 μm
– Surface quality between Ra 1.6 und Ra 3.2
– Circularity / Hole quality for rivets ≤ H8
– Other requirements such as avoidance of delamination.
Working principle for a portable, handheld
NC-programmable L-MAX drilling unit
An L-MAX concept integrates 2 servo motors: The larger motor drives the spindle and the smaller servo regulates the feed. The feed rate is determined by the speed difference between ball screw and ball screw nut or, in other words:
– If the speed (rpm) of the feed servo motor is higher than the spindle motor speed (rpm), then the L-MAX spindle will advance.
– If the speed (rpm) of the feed servo motor is lower than the spindle motor speed (rpm), then the L-MAX spindle will retract.
Both servo motors are controlled by the control system IDM. It allows the user to regulate spindle speed and feed at any position of the total travel.
Furthermore, an adaptive drilling mode can be selected to help improve and optimize a drilling cycle. In this mode, the drill unit recognizes the transition from one layer to the next, automatically. Irregular material thickness of layers at any position are detected and matched with the correct cutting parameters. This way, cycle times can be minimized and machining quality and results optimized.
The control system includes a Minimum Quantity Lubrication (MQL) system, which is directly mounted to the mobile platform.
Performance data drilling unit L-MAX:
– Programmable spindle speed and spindle feed
– Work cycles such as chip brake cycle and peck feed cycle Spindle speed range from 3,000 rpm up to 5,000 rpm
– Drilling capacity from 4.76 mm (3/16”) up to 11.11 mm (7/16”)
– Integrated Minimum Quantity Lubrication (MQL)
– Light weight, depending on drilling capacity, from 5.5 kg (12lbs)
– Quiet operation up to 65 dBA
– Option: Adaptive drilling mode

SUHNER introduces a new and re-designed version of its BEX15 machining unit, capable of a spindle speed increase from 18,000 rpm to 23,000 rpm
Chip producing machining operations with modern tools today demand progressively higher cutting speeds, specifically for metals with high cutting speed rates or small diameter hole drilling applications. The SUHNER machining unit type BEX15, proven in thousands of installations, now provides new speed options, reliably up to the maximum speed limit. With an increase of 25% up to a permissible maximum spindle speed of 23,000rpm, operations requiring higher spindle speeds can be accomplished more easily.
This improvement is the result of a complete redesign of drive and spindle bearing components. A new style timing belt drive multiplies the motor speed up to 13,050rpm spindle speed. An AC-inverter drive is used to increase the spindle speed up to 23,000rpm at 87Hz.
The machining unit BEX15 can be applied in axial and radial orientation, directly mounted to a SUHNER slide assembly type UA15-PH or UA15-CNC. In this combination, numerous machining operations such as milling or demanding drilling cycles, including jump or peck feed, can be accomplished very easily.
Four optional tool holder systems (Collet ER25, ISO30, HSK50 and Weldon) , standard air purge connections for spindle and belt housing including a number of additional options (for example: coolant through the spindle or automated tool change features), make this machining unit type BEX15 highly adaptable and an optimal choice for demanding and specific machining requirements.
