BIG Kaiser Precision Tooling Inc. has introduced Mega ER Grip, a new premium ER collet chuck system featuring a runout accuracy of .00012" (3µm) at 5xD. The Mega ER Grip was designed to outperform all other ER systems in the four most crucial areas of tool holder performance: clamping force, concentricity, rigidity and balance at high spindle speeds. These factors, combined with the system's reliable and stable runout accuracy, amount to significant long-term savings. A major design improvement increases the contact length of the internal taper of the chuck body, reducing the undesired overhang of the collet for significant performance enhancements.
"Our tests have shown that Mega ER Grip performs exceedingly well in these four areas," says Jack Burley, BIG Kaiser vice president of sales and engineering. "The result is cost and down-time reduction thanks to longer tool life. Customers will also see improvements in machining quality and shorter production times because of reduced cutting vibrations."
All components of the Mega ER Grip system are manufactured with BIG Daishowa's production technology: a high-rigidity body, a precision notch-free nut and an AA-grade ERC collet. ERC collets are in accordance with DIN6499 and ISO15488 standards and feature a clamping range of .075" to .787" in diameter.
With the Mega ER Perfect Seal, coolant can be delivered through the tool or to the cutter periphery. Tapped holes around the body periphery promote precision balancing, and the system is only available with dual-contact BIG-PLUS (CAT), HSK and CAPTO interfaces to ensure maximum rigidity.
Workholding device that affixes to a mill, lathe or drill-press spindle. It holds a tool or workpiece by one end, allowing it to be rotated. May also be fitted to the machine table to hold a workpiece. Two or more adjustable jaws actually hold the tool or part. May be actuated manually, pneumatically, hydraulically or electrically. See collet.
Flexible-sided device that secures a tool or workpiece. Similar in function to a chuck, but can accommodate only a narrow size range. Typically provides greater gripping force and precision than a chuck. See chuck.
Fluid that reduces temperature buildup at the tool/workpiece interface during machining. Normally takes the form of a liquid such as soluble or chemical mixtures (semisynthetic, synthetic) but can be pressurized air or other gas. Because of water’s ability to absorb great quantities of heat, it is widely used as a coolant and vehicle for various cutting compounds, with the water-to-compound ratio varying with the machining task. See cutting fluid; semisynthetic cutting fluid; soluble-oil cutting fluid; synthetic cutting fluid.
The larger diameter cutter and new lengths both boost the Fullcut Mill FCM BBT line’s already-considerable versatility, allowing machinists to tailor their tool selections for many different applications. The BIG-PLUS BBT shank products are compatible with both BIG-PLUS and existing BT spindle…
The BIG CAPTO C3 square holders for turning applications come in left and right orientation. The turning application holders—C3-180-BH16R-2058 and C3-180-BH16L-2058—are mono-block holders. Their insert clamps are tough and reliable, adding on to the already inherently high rigidity of mono-block…
The Mega Double Power Chuck system features an expanded contact diameter of the nut to the flange, which provides the highest rigidity—as if the chuck and nut were one solid piece. This superior rigidity ensures heavy duty machining without chatter.
The Base Master lineup is used with all types of machines and materials, including non-conductive cutting tools, workpieces and machine tools. Quickly measure workpiece offsets, tool lengths and cutting edges with zero risk of damage or breakage at submillimeter levels when needed.
The SU Type has a length of 235mm and rubber bellows. The larger MU Type is 360mm in length and has a reinforced ball joint with a large collar. Both use serrated washers instead of flat washers to reduce slippage and increase stability of the center joint.
The Model SDF57 assembly has an outside diameter of 2.83" and allows users of 3" face mills to access up to 19.68" of reach, the longest tool assembly in the industry using standard components. Face milling components used in construction equipment, aerospace and oil/gas industries…
To minimize machine downtime and provide operator safety, these Hydraulic Chucks use a simple hex wrench that requires only two to three turns for both clamping and unclamping. Tightening is complete when the clamping screw hits the bottom; controlling tightening torque is not needed. Once a…
The SW BIG CAPTO Rough Boring Head makes it possible to perform rough and finish boring processes seamlessly with the finishing heads it has offered for years. BIG KAISER currently offers the widest range of rotating BIG CAPTO tooling of any provider.
The Chip Blower automates in-machine cleaning of coolant and chips by delivering high-volume air flow with spindle rotation. When not in use, the Chip Blower fits easily into any automatic tool change system for vertical, horizontal or multi-tasking machining centers. The Chip Blower can be used…
BIG KAISER’s modular CK/CKB system allows for versatility in the length of tooling combinations, up to a maximum of 10 times diameter and can run on nearly every major spindle interface. All tools are coolant-through and have three different insert holder options per head size. The tried-and-true…
