TRM new Advanced Digital Readout TRM International
Milling functions supported include:
• Pitch Circle Diameter (PCD)
This is used for creating a series of holes around a centre point that are exactly equidistant apart. The traditional method of marking out a PCD requires the use of a pair of dividers and a lot of patience and skill, as any engineer knows getting a PCD
right is a difficult task, the DRO makes this task relatively easy and quick to produce accurate results.
• Pitch Circle Diameter Arc (PCD arc)
This option allows the user to undertake complex arc machining, guided by a real time graphical display using the “Trace Me” option that clearly shows the cutting point both digitally and shows the cutting path graphically, plotting the actual and ideal paths.
• Midpoint Calculation
Sometimes it may be necessary to plot the mid point on a vectorial line, the DRO aids the operator in this task by including an easy to use Midpoint Calculator.
Midpoint calculation is easy for the operator to use via the clear and intuitive menu options.
• Line of Holes
Often the operator needs to machine a series of holes for hinges etc. The DRO includes a Line of Holes option, via the easy to use menu, the operator programs the length, start point the number of holes and angle of the line of holes. Lathe functions supported include:
• Taper Angle Calculator
For this, the operator enters the required diameters at either end of the taper and the length of the taper. The DRO will produce a high precision result.
• Taper Angle Measure
This allows the operator to follow the angle that has been calculated, this will then mean that the cut will be more precise and therefore, no errors will occur in the process.
The DRO is based on the highly reliable motion controller, the SMC using the BlackThorn operating system. Because of this, the DRO can accept a wide range of encoders, both
linear and rotary. Accuracy is dependant on the resolution of the encoder used. Encoders are available with a resolution down to as little as 1nm. In some applications the use of a
linear encoder may not be practical, such applications can adopt the use of a rotary encoder.
Other features of the product include multi language support with the choice of English or Spanish (with more languages being supported in the future) The DRO is lightweight
weighing around 1.1kg and low power consumption using around 4 watts. There is also a display size option, of either 3.5” or 5.7” inch LCD colour screen both screen options offer a screen resolution of 320 x 240 pixel and 65536 colours. The product is future proof and a 3 axis version is already being considered
