Outer Edge Inner Edge ZXMT03003-E ZXMT03003GM-I GM-E GH-E SM-E GM-I Criteria for judging tool life How to judge tool life Guidelines for judging tool life Tool marks occur due to large wear In case using new insert In general, since the holder was designed to deflect outward during operation and return to its original position after machining is complete, no tool marks remain. (Depending on the workpiece and cutting conditions, however, in some cases slight marking may occur even with new insert) When the tool has reached the end of its life It starts to bow inward due to increasing cutting forces on the outer caused by increasing wear. Tool marks remain when the tool is retracted because the cutting is in contact with finished surface. Control by drilled diameter Burr generation status at the end Change in cutting noise Change in vibration It can be judged to have reached the end of its life when the drilling diameter suddenly becomes smaller. IIt can be judged to have reached the end of its life when the remaining burrs become large at the end due to the worn outer. Cutting noise increases When the tool gets near the end of its life, there will be stronger vibration and louder noise. It is difficult to confirm these differences in the case of smaller diameter cutters. Caution When drilling through the workpiece, a disk may form and be expelled. Provide proper machine guards to prevent injuries when operating a machine with no cover. Disk 6

When rotati ng the sleeve, insert the wrench supplied with the drill into the hole on the flange periphery to rotate the sleeve. Using the bottom screw of the side-lock arbor, firmly tighten on the drill directly through the sleeve's window.

Check the actual cutting diameter after adjusting.. Center-Height djustment for Lathes Most lathe problems are caused by center height deviation. The center height is appropriate if a core of approximately 0.5mm dia. remains at the center of the end face. Center-height adjustment is necessary in the following cases: No core remains Core diameter is more than 1mm Fig. 1 X-axis of the machine reference mark Fig. lign the drill with the outer insert face parallel to the X-axis of the tool turret. (Fig. 4) lign the scale (for the lathe) on the flange face of the sleeve to the center of the reference mark. When no core remains, rotate the sleeve to (+) direction to make the core larger, and when the core diameter is more than 1mm, rotate the sleeve to (-) direction to make the core smaller. When rotating the sleeve, insert the wrench supplied with the drill into the hole of the flange and then rotate the sleeve. fter Completing the adjustment, tighten the drill directly through the window on the sleeve. Fig. 4 Fig. 3 core Note: Depending on the amount of the center height adjustment, the hole diameter may change. It is recommended that the hole diameter be checked after adjusting the center height. 16

18 Lathe Installation The top face of the outer insert should be parallel to the X-axis to allow for offset cutting. Cutting diameter can be changed by moving X-axis. It is recommended to set the outer insert as shown in Fig. 1 with the outer insert facing the operator. (Fig. 1) (It is also possible to use it by setting it in 180 reverse position.) If the lathe has two turrets, when installing the drill into the lower turret, the outer insert should be set to face the operator. (It is also possible to use it by setting it in 180 reverse position.) Turret Moving direction of X-axis X-axis of the Machine Inner Fig. 1 Installed to the lathe Outer Cutting Diameter djustment 1. Cutting Diameter djustment Cutting diameter is adjusted by moving X-axis. The moving direction of the X-axis depends on the position of the toolholder. In case of making the hole diameter larger, slide the tool along the X-axis toward the outer insert side. (Fig., Fig. 3) For making the hole diameter smaller, slide the tool along the X-axis in the opposite direction. (This movement of the axis is called Offset.) However, be sure not to make the hole diameter smaller than the drill diameter by 0.mm or more. Otherwise, the toolholder will interfere with the drilled hole.(fig. 4) e.g.) When using a ø0 drill, the hole diameter must not be smaller than 19.8mm. X-axis of the Machine Smaller Fig. Outer insert facing up Larger Outer X-axis of the machine Larger Smaller. Offset Limit of the Cutting Diameter For the maximum limit of the cutting diameter, refer to Max. Offset (Radial) in the Toolholder Dimensions table. (The figure in the table shows how much the drill can be offset in the radial direction.) e.g.) When using a ø0 drill, it is possible to make a hole of up to ø1 since "Max. Offset (Radial)" is +0.5mm.

Center Height of the Inn er Insert When installing inner insert as shown in Fig. 1, it will be set around 0.mm below the Center of Spindle.(Fig. 5) This is the normal position of the center height and the drill is designed to be handled in this condition. However, in case that the turret of the lathe is out of the center of Spindle, sometimes the inner insert may be set above the center, or excessively below the center. For stable machining, it is essential to check the Center Height carefully.. How to Check the Center Height For checking the center height of the inner insert, see the core which remains at the center of the end face of the drilled hole. If the center height is in the normal condition, the core about 0.5mm in diameter, will remain after the machining. (Fig. 6) In the following cases, it is necessary to adjust the Center Height. No core remains Core diameter is more than 1mm bout 0.mm below the Center Center of spindle Inner Fig. 5 Front view of the drill Core (about 0.5mm in diameter) * To test the Center Height, drill a shallow hole about 10mm in depth at low feed rate, less than 0.1mm/rev.

In this case, adjustment is necessary since insert breakage will be probable at the center of the drill. Fig. 7 Insert breakage near the center of the drill [How to djust] Install the drill rotated 180. Most problems will be solved by this method. (Fig. 8) Initial Installation (Inner insert positioned higher than normal) X-axis of the Machine Center of Spindle Inner 180 Rotation Improved Position of Inner Insert (Inner insert positioned lower than normal) Center of Spindle Inner If the core diameter becomes too large after the above adjustment, install the drill by rotating 90 counter-clockwise as shown in Fig. 9 (outer is positioned lower), and adjust the center height by moving the tool in the X-axis direction. (However, this makes it impossible to adjust the cutting diameter) Caution: In case of installing the drill in the reverse direction (outer insert is positioned above), the cutting diameter will become smaller, which may cause the drill body to interfere with the drilled hole. The best solution is to readjust the center position of the turret itself.

Core with excessively large diameter (More than 1mm) This occurs when the inner insert is excessively below the center. This condition causes poor chip evacuation and an adjustment is required.

(However, this makes it impossible to adjust the cutting diameter) Caution: When installing the drill in the opposite direction (outer insert is positioned lower), the cutting diameter will become smaller, which may cause the drill body to interfere with the drilled hole. The best solution is to readjust the center position of the turret itself. Inner Fig. 10 Inner 18
