11 y HOLDER (With special surface treatment) External Clamp-on type allows easy indexing. Internal Coolant flows directly to the cutting edge through a coolant nozzle in the center of the shank. By changing the shim, MMT holders can be used for cutting threads with various lead angles. Reduced neck MMT holders prevents chips from jamming. y SUITABLE FOR THREADING WITH A LARGE LEAD ANGLE y VP10MF y VP15TF Lead Angle (% ) y VP20RT Inclination Angle (' ) Insert e u u e Lead Angle (% ) Delivered with the holder. y CHOOSING M-CLASS INSERTS WITH 3-D CHIP BREAKERS OR G-CLASS INSERTS Shim By changing only the shim, MMT holders can be used for turning of threads with various lead angles as well as the turning of left hand threads. (Please refer to page G022, page G025 and page G026) (G-class ground inserts only) a Superior wear and plastic deformation resistance a Suitable for continuous high precision machining with extensive tool life. High wear and plastic deformation resistance for threading when maintaining the thread form is important. Effective in combination with G-class inserts for high precision threading. Inclination Angle (' ) (G-class ground inserts, M-class inserts with 3-D chip breakers) a Wide versatility a Able to withstand harsh conditions for long periods where conventional inserts would be liable to breakage. High fracture resistance during low rigidity applications such as bar feed machining. Effective combination of high cost performance M-class inserts with 3-D chip breakers. (M-class inserts with 3-D chip breakers) a Excellent fracture resistance Suitable for stainless steel boring and unstable machining where inserts are vulnerable to fracturing.

Chip control can be improved by increasing the cutting depth in the later half of passes. Cutting depth and the number of passes yselection of the appropriate cutting depth and the right number of passes is vital for threading. For most threading, use a "threading cycle program," which has originally been installed on machines, and specify "total cutting depth" and "cutting depth in the first or final pass." Cutting depth and the number of passes are easy to change for the radial infeed method, thus making it easy to determine the appropriate cutting conditions. Feature and benefits of Mitsubishi products Insert grades, specially produced for threading tools, ensure highly efficient cutting by enabling high-speed machining and a reduced number of passes. Machining Cost Reduction Advice on improved threading yincreasing tool life To prevent damage to the nose radius - Recommended method - Modified flank infeed. To have uniform flank wear on both sides of a cutting edge - Recommended method - Radial infeed To prevent crater wear - Recommended method - Flank infeed ypreventing chip problems Change to flank or modified infeed. During radial infeed cutting, use an inverted holder and change the coolant supply to a downward direction. When using the radial infeed method, set the minimum cutting depth at around.008 inch to make the chips thicker. Tangled chips during internal threading can damage the insert. In these cases, pause slightly away from the start point and clear the chips with coolant before every pass. Change to M-class inserts with a 3-D chip breaker. yto achieve highly efficient machining Increase cutting speed. (Dependant on the maximum revolution and rigidity of the machine.) Reduce the number of passes. (Reduce by 30-40%.) A reduced number of passes can improve chip discharge because of the thicker chips generated. ypreventing vibration Change to flank or modified infeed. When using radial infeed, reduce cutting depth in the later half of passes and lower the cutting speed. yincreased surface finish accuracy A final pass should be performed at the same depth of cut as the last regular pass. When using the flank infeed method, change to radial infeed only during the final pass. 24

25 Selecting a Shim for the MMT Series Lead angle (% ) yflank angle and lead angle Lead angle (%) depends on a combination of thread diameter and pitch. Select a shim so that the lead angle of the thread can coincide with the flank angles of the thread and insert ($1, $2). When threading with a small diameter or large pitch, change the shim depending on the lead angle, referring to the table and graph below. When threading left hand threads, change to a shim with a negative inclination angle. y Shim reference table (Threading diameter Thread angle 60 and 55 ) Lead Angle Pitch Threading (mm) impossible Threading impossible <&1.7 &1.7 &2.3 &2.3 &3.0 &3.0 &4.6 &4.6 &9.1 >&9.1 <&3.6 &3.6 &9.1 >& <&2.5 &2.5 &3.4 &3.4 &4.6 &4.6 &6.8 &6.8 &13.7 >&13.7 <&5.5 &5.5 &13.7 >& <&3.3 &3.3 &4.6 &4.6 &6.1 &6.1 &9.1 &9.1 &18.2 >&18.2 <&7.3 &7.3 &18.2 >& <&4.1 &4.1 &5.7 &5.7 &7.6 &7.6 &11.4 &11.4 &22.8 >&22.8 <&9.1 &9.1 &22.8 >& <&5.0 &5.0 &6.8 &6.8 &9.1 &9.1 &13.7 &13.7 &27.4 >&27.4 <&10.9 &10.9 &27.4 >& <&5.8 &5.8 &8.0 &8.0 &10.6 &10.6 &16.0 &16.0 &31.9 >&31.9 <&12.8 &12.8 &31.9 >& <&6.6 &6.6 &9.1 &9.1 &12.1 &12.1 &18.2 &18.2 &36.5 >&36.5 <&14.6 &14.6 &36.5 >& <&8.3 &8.3 &11.4 &11.4 &15.2 &15.2 &22.8 &22.8 &45.6 >&45.6 <&18.2 &18.2 &45.6 >& <&9.9 &9.9 &13.7 &13.7 &18.2 &18.2 &27.3 &27.3 &54.7 >&54.7 <&21.9 &21.9 &54.7 >& <&11.6 &11.6 &15.9 &15.9 &21.3 &21.3 &31.9 &31.9 &63.8 >&63.8 <&25.5 &25.5 &63.8 >& <&13.2 &13.2 &18.2 &18.2 &24.3 &24.3 &36.5 &36.5 &72.9 >&72.9 <&29.2 &29.2 &72.9 >& <&14.9 &14.9 &20.5 &20.5 &27.3 &27.3 &41.0 &41.0 &82.1 >&82.1 <&32.8 &32.8 &82.1 >& <&16.5 &16.5 &22.8 &22.8 &30.4 &30.4 &45.6 &45.6 &91.2 >&91.2 <&36.5 &36.5 &91.2 >&91.2 (Note) Back turning in the case of left hand threads. y Shim reference graph(thread angle 60 and 55 ) Pitch (mm) Right Hand Thread %=4.5 %=3.5 Threading impossible %=2.5 Right Hand Thread (mm) %=1.5 (Standard shim) Threading %= 1.5 impossible %=0.5 Threading Pitch (thread/inch) Pitch (mm) Left Hand Thread Flank angle ($2 ) %= 0.5 Flank angle ($1 ) Left Hand Thread (mm) % : Lead angle % : Lead angle Inclination angle (' ) Threading Pitch (thread/inch) (1.97") (3.94") (5.91") (7.87") (1.97") (3.94") (5.91") (7.87") Threading diameter (mm) Threading diameter (mm) Note) When a thread lead angle < the tool flank angle, change the shim to prevent side interference with the insert.

33 TROUBLE SHOOTING Problems Observation Causes Solutions Low thread precision. Threads do not mesh with each other. Incorrect tool installation. Set the insert center height at 0". Check holder inclination (Lateral). Shallow thread. Incorrect depth of cut. Modify the depth of cut. Lack of insert wear or plastic deformation resistance. Refer to "Quickly generated flank wear." and "Large plastic deformation." below. Poor surface finish. Surface damage. Chips wrap around or clog the work pieces. Change to flank infeed and control the chip discharge direction. Change to an M-class insert with a 3-D chip breaker. The side of the insert cutting edge interferes with the workpiece. Check the lead angle and select an appropriate shim. Surface tears. Built-up edge (Welding). Increase cutting speed. Increase coolant pressure and volume. Cutting resistance too high. Decrease depth of cut per pass. Surface vibrations. Cutting speed too high. Decrease the cutting speed. Insufficient work piece or tool clamping. Re-check work piece and tool clamping. (Chuck pressure, clamping allowance) Incorrect tool installation. Set the insert center height at 0". Short tool life. Flank wear quickly generated. Cutting speed too high. Too many passes causes abrasive wear. Decrease the cutting speed. Reduce the number of passes. Small depth of cut for the finishing pass. Do not re-cut at 0" depth of cut. Depth of cut larger than.002" is recommended. Non-uniform wear of the right and left sides of the cutting edge. The work piece lead angle and the tool lead angle do not match. Check the work piece lead angle and select an appropriate shim. Chipping and fracture. Cutting speed too low. Increase cutting speed. Cutting resistance too high. Increase the number of passes and decrease the cutting resistance per pass. Unstable clamping. Check work piece deflection. Shorten tool overhang. Recheck work piece and tool clamping. (Chuck pressure, clamping allowance) Chip packing. Increase coolant pressure to blow away chips. Change the tool pass to control chips. (Lengthen each pass to allow the coolant to clear the chips. Change from standard internal cutting to back turning to prevent chip jamming. Non-chamfered work pieces causes high resistance at the start of each pass. Chamfer the workpiece entry and exit faces. Large plastic deformation. High cutting speed and large heat generation. Lack of coolant supply. Decrease the cutting speed. Check coolant is supply is sufficient. Increase coolant pressure and volume. Cutting resistance too high. Increase the number of passes and decrease the cutting resistance per pass. 33
