**Shrink-Fit Holders**: The Slimline series includes models such as 2 Piece Type Modular, Mono 3°, Mono Curve, Uno, Hyper Version, Slimline Z, and Straight Arbor. These holders feature special steel and a simple design, preventing overheating and enabling low-temperature shrinking. MST's special steel boasts a thermal expansion coefficient 1.6 times greater than conventional steel, allowing for low-temperature shrink fitting at 300℃. An ultra-slim design with a holder tip wall thickness of 1.5mm expands the machining area. The Slimline Uno model offers superior accuracy of 0.5 micrometers (μm). The 2 Piece Type Modular system provides over 4,000 combinations.**Shrink-FitHolders**:TheSlimlineseriesincludesmodelssuchas2PieceTypeModular,Mono3°,MonoCurve,Uno,HyperVersion,SlimlineZ,andStraightArbor.Theseholdersfeaturespecialsteelandasimpledesign,preventingoverheatingandenablinglow-temperatureshrinking.MST'sspecialsteelboastsathermalexpansioncoefficient1.6timesgreaterthanconventionalsteel,allowingforlow-temperatureshrinkfittingat300℃.Anultra-slimdesignwithaholdertipwallthicknessof1.5mmexpandsthemachiningarea.TheSlimlineUnomodelofferssuperioraccuracyof0.5micrometers(μm).The2PieceTypeModularsystemprovidesover4,000combinations.
**Shrink-Fit Heaters**: The HEATROBO DENJI 2500 is a 2.5kW induction heater, capable of using a single heating coil for 3 to 16mm diameter holders. It operates on a 200-240V single-phase power supply, eliminating the need for a transformer outside Japan. The Heat Robo Automatic Shrink-Fit System automates the shrink-fit process for Slimline holders. It incorporates a holder-friendly, safe design considering tool holder and heating coil temperatures, utilizing electromagnetic induction heating. The system supports tool diameters φ3–8 and HSK-E25/E32/E40/F63 holders. An efficient one-touch cooling system enhances operational speed.**Shrink-FitHeaters**:TheHEATROBODENJI2500isa2.5kWinductionheater,capableofusingasingleheatingcoilfor3to16mmdiameterholders.Itoperatesona200-240Vsingle-phasepowersupply,eliminatingtheneedforatransformeroutsideJapan.TheHeatRoboAutomaticShrink-FitSystemautomatestheshrink-fitprocessforSlimlineholders.Itincorporatesaholder-friendly,safedesignconsideringtoolholderandheatingcoiltemperatures,utilizingelectromagneticinductionheating.Thesystemsupportstooldiametersφ3–8andHSK-E25/E32/E40/F63holders.Anefficientone-touchcoolingsystemenhancesoperationalspeed.
**Other Tooling Systems**: The product lineup includes collet chucks, milling chucks, angle heads, DETa-1 collet holders, milling arbors, spindle cleaners, test bars, work-holding fixtures, and preventive maintenance tools. Lightweight angle heads are particularly suitable for hard-to-reach machining applications.
