HMC Collet Chuck Output | Orientation: Radial","description":"\u003cp\u003eThe Big Daishowa BCV50-AG90\/HMC1.250-230S is a 90-degree right angle head built for heavy-duty end milling on horizontal machining centers. It uses the BIG-PLUS dual-contact CAT50 spindle interface, which provides simultaneous taper and flange face contact for improved rigidity and repeatability compared to standard CAT50 tooling. The output side uses Big Daishowa's HMC Hi-Power Milling Chuck system with a 1-1\/4 inch clamping diameter, designed to accept large-diameter end mills under high cutting loads. Overall gage length is 230mm with a long-reach (HR) configuration. The nameplate confirms a 1:1 speed ratio and a forward maximum speed of 3,000 RPM. The angular head body is machined from steel and incorporates hardened spiral bevel gears for torque transmission to the 90-degree output spindle. A degree-graduated collar visible in the photos allows for indexed rotation of the output spindle housing, enabling angular positioning for multi-face machining without repositioning the workpiece. The BIG-PLUS spindle system designation and Big Daishowa Angle Head branding are engraved on the tool collar. Part number BCV50-AG90\/HMC1.250-230S appears on the blue nameplate label along with serial reference NCH228RL. This unit is suited for HMC applications requiring a large-bore milling chuck output with maximum torsional stability.\u003c\/p\u003e\n\n\u003cp\u003eStock # 0426-02118\u003c\/p\u003e","brand":"Big Daishowa","offers":[{"title":"Default Title","offer_id":49624846729456,"sku":"m02118","price":3999.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0797\/6648\/7280\/files\/36219F15-C09F-49E1-BAA9-7F70ABAAAEF1.jpg?v=1777409377","url":"https:\/\/mroexchange.com\/products\/big-daishowa-right-angle-head-bcv50-ag90hmc1250-230s-cat50-1-14-in-hmc-collet-chuck-output-orientation-radial-02118","provider":"MRO Exchange","version":"1.0","type":"link"}
