Q-5 Tool markings are made on the finished surface. Is there any countermeasure During processing, force of deflection is applied to the center of the drill. If the drill is just pulled out from the position where processing is finished, tool markings will be made. To prevent tool markings, perform offset before pulling out the drill. Example of tool marking How to prevent tool markings (1) Drilling the hole (The spindle revolves) (2) Turn back approximately 0.5 mm (The spindle revolves) Chips are adhering to the bottom when drilling stops. Without turning back, chips remains adhering to the bottom. If offset (3) is performed without turning back, the bottom of drill contacts with the inner surface of hole. Turning back is necessary for blind holes but not for through holes. (3) Stop revolution and perform offset (The spindle stops) (4) Pull out the drill Avoid contact Make a ' clearance to prevent the tool from contacting when pulling out. (Approximately 0.1 to 0.2 mm) Example of drilling program G90G54G0G43X0Y0Z100.0H10 S477M03 Z2.5M8 G01Z-80.0F48 Z-79.5M19 The spindle stops X0.2Y0.2 at the specified position Z100.0M9 The M code and X and Y moving directions are unique to the equipment. Tool markings are not made (or are only slight even if made).
