MSR Q-1 A-1 Q-2 A-2 Q-3 Q-6 A-6 1st Pass 2nd Pass What cutting conditions are recommended in most cases for MSR Vc=150m/min,fz=0.2mm/t, larger cutting depth and smaller cutting width Required equipment for MSR Max. spindle revolution is under 4,000min 1. BT50 or larger. MSR is not only for Double column machining center. The reason why not recommended for high RPM spindle machine is its less torque. Although MSR works with BT40 shank, maximum available fz is about 0.1mm/tooth. What is the points to remember in case of less power machine 1 In case of MSR100R-2 e.g.) Load meter 120% I e.g.) Load meter 90% ll I I l 3rd Pass apxae. 15x75mm - 3rd Pass 2nd Pass apxae. 45x25mm 1st Pass >/ A-3 Q-4 A-4 Do not use large size cutters. 63 or 80 is 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. Tried under condition of Vc=150m/min, enough torque was not gained because of high gear. In this case, it has to be prioritized using Vc which can exert enough torque as Vc=120m/min. Machine torque curve will be prioritized. In case of unstable workpiece. Decrease feed ratio at the start machining the workpiece. 1 Almost all cases of moving workpiece happens when start machining. >/ Effective for increasing cutting speed and decrease feed rate. Vc=150m/min,f z=0.2mm/t I Vc=200m/min,f z=0.15mm/t Q-5 A-5 What is the tool life Chip weight: 700kg/Corner (Result by PR660) Cutting time: 90min. (calculated value) Cutting distance: 65m (calculated value) How great 1,000cc/min About 7.8kg chips removed per minute Tool life time=700kg (Chip weight) 7.8kg (Chip evacuation amount per 1min)=90min Cutting distance=90min (Time by the end of tool life)x717mm/min (Table feed ratio per 1min)= In case of cutting Vc=150m/min, apxae: 20x70mm, Vf=717mm/min. Tool: MSR100R-2 (6 inserts) How to reduce chattering. In chattering occurs, then the following conditions are recommended. Reduce cutting speed and increase feed rate. 65m In case of Steel V c=80m/min f z=0.25mm/t In case of Cast Iron Vc=80m/min f z=0.35mm/t Lead Angle 45°'20c Lead Angle 15° ' Lead Angle 0°/2° High Feed Cutter Multi- Function Ball-nose Radius Q&A Slot Mill M118
