1 MFour (MW) How to mount an insert 1. Be sure to remove dust and chips from the insert mounting pocket. 2. Apply antiseize compound on portion of taper and thread of clamp screw. (1) Attach the screw (magnetic head) to the front end of the wrench. (2) While lightly pressing the insert against the pocket walls, put the screw into the hole of the insert and tighten. (Ref. to Fig. 1.) Tighten M3 screws (SB3065TRP) slightly inclined from the insert. (Ref. to Fig. 2.) surface of the insert When tightening the screw, make sure that the wrench is parallel to the screw. For recommended torque, Ref. to 7 4. After tightening the screw, make sure that there is no clearance between the insert seat surface and the pocket floor of the holder or between the insert side surfaces and the pocket walls of the holder. If there is any clearance, remove the insert and mount it again according to the above steps.

4 MSix (MFWN) Precautions for use (How to mount the insert) 1. Be sure to remove dust and chips from the insert mounting pocket. 2. After applying antiseize compound on portion of taper and thread, attach the screw to the front end of the wrench. While lightly pressing the insert against the pocket walls, put the screw into the hole of the insert and tighten. (Ref. to Fig. 1) 3. When tightening the screw, make sure that the wrench is parallel to the screw. Remember that the screw hole of the holder for xtra fine pitch is inclined to the pocket floor. (Ref. to Fig. 2 and Fig. 3) 4. Be careful not to tighten the screw with excessive torque. Recommended torque is 4.2N m for M5 screw (SB50140TR) and 3.5N m for M4 screw (SB40140TRN). 5. After tightening the screw, make sure that there is no clearance between the insert seat surface and the pocket floor of the holder or between the insert side surfaces and the pocket walls of the holder. If there is any clearance, remove the insert and mount it again according to the above steps. 6. To change the cutting edge of the insert, turn the insert counterclockwise. (Ref. to Fig. 4) The insert corner identification number is stamped on the top surface of the insert. 0 Recommended Conditions Insert Grades Speed Vc (sfm) Carbon Steel PR Alloy Steel PR Mold Steel PR Stainless Steel PR Gray Cast Iron PR Nodular Cast Iron PR Titanium Alloys PR Chipbreaker GM SM GH GL GM SM GH GL GM SM GH GL GM SM GL GM SM GH GL GM SM GH GL SM GL Vertical milling Coarse pitch (with shim) Fine pitch (without shim) Cutter (For GH Chipbreaker, fz=0.0118ipt is Specification recommended.) xtra fine pitch (without shim) (The use of the GH breaker is not recommended.) * The boldfaced number indicates a center value of recommended condition. : 1st Recommendation : 2nd Recommendation All items Max.

Vc=500sfm, fz=0.008ipt, larger cutting depth and smaller cutting width What is the required equipment for MSR? In case of MSR100R2 e.g.) Load meter 120% e.g.) Load meter 90% 1st Pass 2nd Pass 3rd Pass ap ae: in Maximum spindle revolution should be lower than 4000RPM. BT50 or larger. * The reason it is not recommended for high RPM spindle machines is due to their lower torque value. * Although MSR works with BT40 shank, maximum available fz is about 0.004ipt. What are the points to remember when using a lower horsepower machine? 3rd Pass 2nd Pass 1st Pass ap ae: Do not use large size cutters. Ø2.5" or Ø3.0" are recommended Please increase cutting speed and decrease feed rate. Set up conditions to get the largest available torque by checking torque curve of the machine. In conditions of Vc=500sfm, insufficient torque was amiable due to being in high gear. In this case, use Vc which can exert enough torque, such as Vc=400sfm. * Machine torque curve is a priority. 0 Q4 How do I deal with an unstable workpiece? Decrease feed rate during the ffective combinations for maintaining cycle time while A4 initial cut. Q5 What tool life can I expect? * Vibration and workpiece movement are most likely to occur upon the cutters initial entry entry into the cut. reducing the feedrate. Vc=500sfm, fz=0.008ipt Vc=650sfm, fz=0.006ipt A5 xample: Chip weight: 700kg/Corner (Result by PR660) time: 90min. (calculated value) distance: 65m (calculated value) Metal Removal Rate? About 7.8kg chips removed per minute Tool life time = 700kg (Chip weight) 7.8kg (Chip evacuation amount per 1min)=90min distance= 90min (Time by the end of tool life) x 717mm/min (Table feed ratio per 1min)=65m * Vc=150m/min, apxae: 20x70mm, Vf=717mm/min. * Tool: MSR100R2 (6 Flutes) Q6 How do I reduce chattering? If chattering occurs, then the following conditions are recommended. A6 Reduce cutting speed and increase feed rate. In case of Steel Vc=250sfm fz=0.010ipt In case of Cast Iron Vc=250sfm fz=0.014ipt 61 61
