Product Description Product Detailed DescriptionThe HSK125A-FMC40-60 Toolholder is a specialized precision clamping system engineered for heavy-duty milling and drilling operations in CNC Vertical Machining Centers (VMCs) and Horizontal Machining Centers (HMCs). It integrates the stability of the HSK125A dual-contact taper interface with the versatility of an FMC40 flange milling chuck-designed exclusively to secure shank-type cutting tools (e.g., end mills, face mills, twist drills) rather than flange-mounted tools. This makes it ideal for industries like mold & die manufacturing, automotive component machining, and heavy machinery fabrication, where rigid tool clamping and minimal runout are critical for high-precision cuts.Core Design & Engineering AdvantagesHSK125A Dual-Contact Taper Interface: Complies with ISO 1940-1 standards, featuring a hollow 1:10 taper with simultaneous taper + face contact (dual-location). This eliminates radial runout (≤0.003mm at 3×D from the chuck end) and axial movement, ensuring consistent tool concentricity-critical for deep-slot milling or high-feed drilling where vibration causes tool wear.FMC40 Flange Milling Chuck Function: Unlike FMB (flange mill base) toolholders (for flange-mounted mills), the FMC40 designation denotes a clamping chuck with a 40mm nominal flange diameter. It uses a collet or setscrew mechanism to grip shank-type tools (typically ISO metric shanks: 10mm-20mm diameter, depending on collet size), enabling quick tool changes while maintaining clamping force (up to 8kN) for heavy cuts.Optimized 60mm Length: The 60mm overall length (from HSK taper reference face to FMC chuck end) balances tool reach and rigidity. It avoids excessive overhang (a common cause of chatter) while providing enough clearance for machining deep cavities or large workpieces (e.g., engine blocks, mold bases).High-Strength Construction: Machined from heat-treated 42CrMo alloy steel, quenched and tempered to HRC 45-50. The material's high fatigue resistance (≥800 MPa yield strength) withstands repeated clamping cycles and high cutting loads (up to 12kN axial force), extending toolholder service life.Optional Through-Coolant System: Available with integrated 3mm-diameter coolant channels that direct high-pressure coolant (up to 15 bar) through the chuck to the tool's internal cooling holes. This feature reduces thermal wear on tools (e.g., carbide end mills) when machining stainless steel or high-temperature alloys, extending tool life by 30%.Model BreakdownThe HSK125A-FMC40-60's model code is standardized for clarity-critical for industrial procurement: Model SegmentDefinitionHSK125AHSK taper size: 125mm nominal diameter, A-type (hollow, 1:10 taper ratio)FMC40Flange Milling Chuck: 40mm flange diameter, designed for shank-tool clamping60Overall length: 60mm (from HSK taper reference face to FMC chuck end)Machine & Tool CompatibilityCNC Machines: Fits HMCs/VMCs with HSK125A spindles (e.g., Mazak VTC-800/30SR, DMG MORI NHX 8000, Haas UMC-1600SS).Cutting Tools: Designed for shank-type tools with metric shanks (10mm-20mm diameter), including:Solid carbide end mills (4-flute, 6-flute)Indexable end millsTwist drills (HSS or carbide)High-feed milling cuttersApplication & Compatibility The HSK125A-FMC40-60 is purpose-built for shank-tool machining-filling a critical gap vs. FMB toolholders (for flange mills). Key use cases include:End Mill Machining: Clamps 12-20mm diameter carbide end mills for roughing/finishing mold cavities (P20 steel) or automotive transmission housings (40Cr steel), leveraging low runout for consistent wall thickness (±0.01mm).Drill Machining: Secures twist drills or indexable drills (e.g., U-drills) for deep-hole drilling (up to 5×D) in cast iron (HT300) pump bodies, with through-coolant ensuring efficient chip evacuation.Shoulder Milling: Holds square-shoulder end mills for machining 90° shoulders on alloy steel (20CrMnTi) gear blanks, where dual-contact rigidity eliminates chatter-induced burrs.General Heavy-Duty Milling: Compatible with high-feed mills for rapid material removal in carbon steel (S45C) structural components, reducing cycle time by 25% vs. less rigid ER-collet toolholders. User Benefits Precision-Driven Tool Life: ≤0.003mm radial runout reduces tool wear by 25%, lowering per-part tool costs for high-volume production.Rigidity for Heavy Cuts: Dual-contact HSK125A + 42CrMo construction eliminates vibration, enabling deeper cuts (up to 8mm depth of cut in steel) without tool deflection.Versatile Tool Clamping: FMC40 chuck design replaces multiple ER-collet holders, streamlining tool inventory by 40%.Durability & Safety: G2.5 balance rating ensures safe high-RPM operation, while black oxide coating resists coolant corrosion-backed by a 12-month warranty against manufacturing defects.
