HydroForce HTTM: Universal Hydraulic Chuck Maximizes High-Torque Performance

11 May 2015

First choice for all rotating applications

With among the highest levels of transmittable torque due to a more compact design, featuring a 40% thicker front-wall cross-section, the new HydroForce HT universal hydraulic chuck from Kennametal is a cost-effective chucking solution that simplifies inventory while maximizing tool life and machining results for milling, drilling, reaming, and other rotating applications.

HydroForce HT provides the increased rigidity necessary for improved cutting parameters and better results. Clamping force is up to three times better than regular hydraulic chucks, and with improved vibration dampening, runout is three microns at 2X diameter overhang. Balance quality of G2.5 is achieved at speeds up to 25,000 rpm.

"All this robust performance is available in a high-torque chuck requiring only two sizes for all your rotating tooling tasks," according to Kennametal. Direct clamping is available for 20 and 32 mm (0.75 and 1.5 in.) diameters and reducer sleeves are applied for all other diameters.

Maximum Torque AND Resisting Bending Loads

When machining tough materials like titanium, cutting speeds are relatively low due to thermal effects on cutting tools. In response, machine-tool builders have improved stiffness and damping on spindles and machine structures to deliver abundant torque at low rotational speeds.

In these and other cases, the HydroForce HT universal chuck works directly with the Kennametal KM4XTM spindle connection to not only transmit higher levels of torque, but also provide maximum resistance to bending loads. In end-milling applications, where projection lengths are typically greater, the limiting factor is the spindle interface�'s bending capacity. For example, an indexable helical cutter with 250mm (9.84 in.) projection from spindle face, 80mm (3.15 in.) in diameter generates 4620 Nm (3407.5 ft. lbs.) of bending moment and less than 900 Nm (663.8 ft. lbs.) of torque. Often, bending moment boundaries are exceeded far before torque levels.

The combination of the KM4XTM system�'s high clamping force and interference level lead to a robust connection and extremely high stiffness and bending capacity for greatly improved performance in titanium machining. KM4X and HydroForc Ht work together to overcome the limitation on bending capacity present in other connections. Maximum available spindle power and torque are brought to bear every time in critical operations like milling of high-strength materials.

Complete Product LineKennametal's hydraulic chucks are among the world's leading toolholder systems. Other choices include BASIC-Line expansion chucks, TREND-Line, HP Line with radial tool-length adjustment, and SLIM-Line for long L to D ratios. The hydraulic chucks are characterized by low maintenance costs. All hydraulic chucks are equipped with central coolant for use with through-coolant or non-through-coolant tools, and can also be applied in minimum quantity lubrication (MQL) situations.
