This DRO can offer "MAX CUT" or "Z STEP" for choices. If "MAX CUT" selected, the ARC or R function calculation will interoplated the ARC in fixed cutting distance for smooth ARC machining.

Page 113 FLTR. PR. menu is designed to allow user to specifies the filtering range of vibration for the vibration filtering function. This version of software is offering vibration filtering as one of the standard function in the ES-12. This function is used prmary for big or very old machine which the machine structure is not ver y rigid to resist the vibration when during machining or axis movement.
Page 114 Easson Always Committed to Quality Technology & Innovation Installation Instructions A. Precaution: 1. The travel length of the glass grating scale must be longer than the maximum travel of the machine, there should be at least 10mm clearance between the ends of the glass scale and the maximum travel of the machine as per the following figure shown.
Page 115 Easson Always Committed to Quality Technology & Innovation . The following considerations must be taken to select the proper installation locations (1) Scales should be installed on to a machined surface. (2) The opening of the scale must not be installed as to be directly exposed to swarf, oil. Water .dust or other foreign products.
Page 116 Easson Always Committed to Quality Technology & Innovation . All the tapped screw holes must have at least 6 threads to allow the screw to be firmly secured into the tapped holes. For the screw that is needed to secure a heavy load, the tapped holes must have at least 8 threads.
Page 117 Easson Always Committed to Quality Technology & Innovation B. Installation standards & Requirements 1. Requirements for the mounting surface a) If the scale mounting surfaces are not parallel to each other (i.e. As per shown in figure A and B), the parallelism of the two mounting surfaces must be less than 0.1mm.
Page 118 Easson Always Committed to Quality Technology & Innovation 3. Clearances between the reader head and scale body: (1) The clearance between the reader head and scale body must be kept between 0.8mm-1.5mm. (2) The reader head must be less than 0.5mm parallel with the scale and can be set with feeler gauges to allow the reader head to move unrestricted along the scale.

Page 120 Easson Always Committed to Quality Technology & Innovation After the scale is aligned to the axis, then drill and tap the scale to suit the bracket provided and mount the bracket insuring that the reader head is sitting correctly so that when the reader head is attached it will be square and parallel to the scale.
