2 Feature of Flute Design Recommended on a wide range of soft materials Raw materials and Hardened steels up to 55 HRC. Variable Helix design and Positive Rake angle offers stable milling under high speed conditions. High-rigid and Seamless corner radius reduces the cutting force. Variable Pitch Seamless Corner Radius Variable Helix Milling Example CXLRS (φ x Effective length 2 x C)Ramax(32HRC) Material : RAMAX 32HRC Size : 500 x 500 mm Coolant : Air Blow Milling method : Vortex Spindle Speed :1,000 rpm (Max spindle speed of the machine) Feed Rate : 7,000 mm/min (Fz: 0.1mm/tooth) Axial Depth : mm (2 X ) Radial Depth : 0.5 mm (Around % of ) Rough Milling Video Ramax (32HRC) 2

These milling parameters are for reference only. For best result, fine parameter adjustments may be required, depending on the milling shape / application / machine used and so on. Decrease both spindle speed and feed rate proportionally when the milling parameters exceed the machine's maximum spindle speed. WARNING: Because of high material removal rate, you must pay attention to your chip and coolant management. Side Milling a p:axial Depth a e:radial Depth Advisory for Safe Use of UNIMAX Tungsten Carbide End Mills Correct application and operation is strongly advised to avoid clogging, abrasion, etc, that could cause serious accidents or injuries. Ignition or sparks generated during milling could lead to fire or extreme damage to the work piece. End Mills are made with very sharp cutting edges and must be handled with extra care. Never touch the cutting edge with your bare hands, as this could cause serious injury. Special caution is required when opening the package. Dropping the tool could cause breakage or flying debris, leading to serious injury. During milling, unexpected impact or shock on the tool could cause breakage or flying debris. Ensure to use protective items such as safety glasses and a face guard. For best results, fine parameter adjustment may be required, depending on the materials; milling shape and strategy; machine rigidity and spindle capability. Use a machine that has high rigidity and generates a low level of vibration. Do not use flammable cutting oils. Advisory for regrinding UNIMAX Tungsten Carbide End Mills Never regrind the tool without wearing safety glasses and a face guard. U.S. HEADQUARTERS 0 N.
