Some of the important machines Rompa Group utilizes in the tool room are the CNC milling/drilling machines 3-axle and 5-axle, e.g. Hermle with robot/pallet system and CNC HSM (High Speed machine), Yasda for high-accuracy milling work. These machines give us possibilities for not only shaping, but also for making slots, holes, pockets or notches. In general it always starts with making a proper design, after that we apply the instruction into a CAS system in either 2D or 3D format, depending on the project. From there on the machine follows the instructions dictated by the design and it creates the piece out of the specific material that has been chosen.
At Rompa Group we have both the 3-axis mill and 5-axis mill. So what's the difference? Using our 3-axis vertical mill the table moves in 2 directions, X and Y, to position the workpiece. The third one is the Z-axis. We lower or raise the cutting tool making our 3-axis vertical mill complete.
Before switching to the 5-axis mill, there is also a 4-axis mill. The 4-axis mill has the same features as the 3-axis mill but has one option added. The 4-axis mill has the A-axis and this means that the table can rotate around the X-axis.
Like the previous mills, the 5-axis mill has the same features and again one is added. The 5-axis mill consists of: X, Y and Z axis but also A and B axis. Where A rotates around the X-axis, B rotates around the Y-axis. This mill gives us the possibility to produce or adjust the most complex parts.
