BK Mikro TK9LIN series is a scanner, which utilizes a rack and pinion for probing tooling, part features or assembly applications. There are two models available with different strokes: 50mm and 100mm.
The complete BK MIKRO Linear system includes:
- Control unit - BKM91, BKM92 or BKM93
- I/O Unit- BKM9I/O (optional)
- Scanner (motor) – TK9LIN50 or TK9LIN100
- Connection cable – BKC5
- Mounting Bracket - BKMB
BK Mikro Linear is based on the existing design concepts for tool, object and free space monitoring and is modified to utilize a rack and pinion probe instead of a wand. This system monitors a specific distance or depth with longitudinal scanning. This is especially useful in cases where rotary scanning is inappropriate or impossible. Some examples would be cavities, blind or through holes and places where space is limited. It can also be used to verify a part is in place during assembly or that the proper part is on the machine by probing a specific feature.
Principle of Operation:
Once a position is set either with a Teach/Learn or via the rotary switches on the BKM9I/O the system is ready for operation. Simply apply a 24vdc signal to the “Start” terminal to initiate the scanning cycle (this can be done via the CNC, PLC or with a relay). The probe will move to the taught position and verify that the tool or object is present within the set tolerance range. If everything is alright the unit will output an “OK” signal to allow the machine cycle to continue. If the tool is broken the probe will travel past the stored position and the controller will output a “KO” signal to let the machine know there is a problem and shut down automatically. The checked tolerance can be adjusted through the software, via dip switches or the rotary dials. Standard tip options are available or some customers make their own custom tips to thread onto the probe.
