Indexable Tools Tooling by DIJET Swing Ball SWBTYPE Applicable range is from soft material to welded and hard material. For high efficiency and longer tool life. 1. Smooth and calm cutting and low cutting force at higher feed rate. Cutting force is reduced by 25% compared with conventional type. This is achieved by using a positive style insert with chipbreaker groove and edge notches. Double insert desgin gives smooth cutting action and excellent cutting. 2. Plunge cutting is possible because of better crack resistance on nose cutting nose portion. Providing sub chip pocket at spiral nose cutting edge ejects chips smoothly and improves crack-resistance (except for Semi-finishing insert -H type) 3. Reliable insert location and improved security for heavy operations. By providing key on the back face of insert and cutter body, insert movement is prevented. Impact of cutting load is secured. 4. Special surface harding treatment on thermal resistant high strength steel gives high hardness over 65HRC and secure insert pocket and holder against thermal deformation. Improved body durabilty and tool life by 30% or more. Make it difficult to be damaged even under severe cutting conditions. Also rust-proof and anti-welding effect is much improved. Insert Series Expansion Available now 3 type inserts suitable for various uses: ① Low Cutting Force ② Welded & Hardened Material ③ Semi-Finishing ① Inserts for low cutting forces (-N type) 1. 15% reduced cutting force compared with regular type. More smooth and calm cutting is possible. 2. 1.7 times longer tool life than conventional tool. 3. Chip breaking & ejection are improved by adopting notches on the cutting edge. ■ CUTTING PERFORMANCES Completely breaking chips by notch Body: SWBS5060C508 ■ CHIPS COMPARISON (φ50)Material:SKD11(217HB) Down cut Up cut Cutting: n=1,350min-1 Main blade Sub blade Main blade Sub blade Conditions: f=0.6mm/rev ae=10mm SWB-N type ap=10mm (New type) Smooth cutting SWB type (Conventional type) Not completely breaking chips by notch C156
