Desktop-sized micro hole drilling machine, BISSIAH XZ150
Challenging the limits of micro hole machining
The micro hole drilling machine BISSIAH XZ150 uses the latest developed technology based on the micro drilling technique cultivated for the lathe type micro hole drilling machine, BISSIAH ML10. This desktop-sized drilling machine enables the drilling of many holes in a plate or a similar workpiece.
The drilling spindles are equipped with high-sensitivity process (reaction) force sensors to detect the stress of the drill of φ0.02-0.3 mm in diameter. The sensors simultaneously detect the torque which is the force in the direction of twisting, and the thrust force which is the force in the direction of pressing back. They feed back the detected forces to the control system of the BISSIAH in real time.
For example, you can imagine easily that a thin drill 0.05 mm in diameter, which is about half the diameter of a human hair, is very fragile even against a delicate force. By detecting such a delicate force, BISSIAH enables you to drill a micro hone deeply even in a "hard to process" material.
Features of BISSIAH
- Equipped with two spindles; the center hole drilling spindle and the micro hole drilling spindle, to reduce the frequency of tool changes
- Supported by the in-house developed aerostatic bearings, each spindles keep the run-out within 100 nanometers.
- The XY table oriented vertically for easy discharge of the chips. Maximum processing range: 150 mm(100mm when both spindles are used simultaneously).
- The least input increment of the XY table is 1 μm. Mounting the linear scale fully closed for high precision control.
- The leading edge position of the tool automatically detected with the thrust force sensor
- Easy input of machine operation, drilling conditions, and drilling location at the LCD touch screen
- Two CCD cameras to display an enlarged view of the drilling area
- Semi-dried machining with automatic spraying of cutting oil: minimizing scattering of cutting oil by fully covering the machining area.
- Provide the processing conditions and parameters with various materials (optional).
