Complete with a built-in digital display, BIG Kaiser's new Series 112 EWD 2-54 Digital Precision Finish Boring Head allows operators to make precision adjustments on the fly. The digital unit utilizes accessories from the Kaiser EWN 2-50XL series and features through-tool coolant supply and a maximum spindle speed of 20,000 RPM.
The head, with a Kaiser KA6 modular connection, features absolute setting accuracy. An on-board electronic measurement system in the tool carrier allows for ultra-precise diameter adjustments for the boring range .079" to 2.126" in diameter. For ease of use, a single button is all that is needed to operate the digital readout. The large, high-contrast display relates diameter corrections with a resolution of .00005"/diameter, or .001mm/diameter on metric heads. The tool carrier's measuring system shows the effective movement of the cutting edge and permits diameter corrections in both directions.
"By making the readout easy to read, adjust, and use, the Series 112 EWD 2-54 Digital Precision Boring Head will ensure accuracy while eliminating operating errors, saving time and labor," says Jack Burley, BIG Kaiser vice president of sales and engineering.
The boring head's digital features include a power management system for optimal battery life and an automatic switch-off function which automatically saves the most recently displayed value. The coated tool body offers complete protection against corrosion, and a seal rating of IP 69K assures the internal components are protected in the most extreme environments.
Enlarging a hole that already has been drilled or cored. Generally, it is an operation of truing the previously drilled hole with a single-point, lathe-type tool. Boring is essentially internal turning, in that usually a single-point cutting tool forms the internal shape. Some tools are available with two cutting edges to balance cutting forces.
Single- or multiple-point precision tool used to bring an existing hole within dimensional tolerance. The head attaches to a standard toolholder and a mechanism permits fine adjustments to be made to the head within a diameter range.
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…
