SEC- Boring Bar Series Complete Support For Boring Operations For Turning ■ General Feature The SEC-Boring Bar Series is a collection of SEC-Small Diameter Boring Bars, a product we began selling in 1976 which continues to be popular today, steel/carbide shank holders with a highly rigid head design, SumiTurn X Bar which includes a vibration control mechanism, and optimized insert grades and chipbreakers. ■ Characteristics ● Compatible with a wide variety of tooling Stop boring / bottom facing / through boring / profiling ● Minimum machineable diameter: CKB model ø 1 mm–, C-SCLC model ø 5mm– ● Vibration control boring bar, SumiTurn X Bar ● Carbide short shank is compatible with turret lathes even without cutting (C15M-STUP model, C20M-STUP model) E ● Insert grades and chipbreakers compatible with a wide variety of work materials ■ Steel Shank Type ● Dramatically improved chatter resistance, especially effective for rough machining of deep holes Boring Bars With Vibration ● Achieves low cost machining for large diameters/deep holes, shank diameters up to ø32 mm Control Mechanism are in stock ● High chip evacuation performance, evacuates chips with double chip pocket ● Types with oil hole are in stock ● Holders for negative inserts (shank diameter ø25–ø50 mm) are in stock Assists evacuation of chips New vibration control mechanism X New head design Effective Chattering Killer System X bar cross section Evacuation of Evacuation of long chips short chips Direction to which vibration generates during cutting Flattened weight vibrates with opposite phase from the chatter Strong cross-section High rigidity rib and dramatically reduces chatter! withstands high cutting forces ■ Shank Material Selection Steel Shanks With Vibration Control Bar type Steel shank with vibration Mechanism, Clamp Position Precaution Machining method Steel shank control mechanism Carbide shank Shallow hole G S General (L/D ＜ 3) Economical High speed machining steel Deep hole G G Label (L/D ＞ 3) Economical attachment area High efficiency machining S G Vibration control may not work correctly if the area near with wiper insert the label is clamped (due to containing Hardened steel/ the vibration control mechanism). Q G Therefore, the minimum protrusion length is set at 3.5 D hardened steel machining (3.5 times shank diameter). High-precision G machining G: 1st recommendation S: 2nd recommendation E8
