A new deep-hole microdrill from BIG Kaiser's Sphinx line provides a time-saving option for creating wire EDM starter holes, averaging 5X faster per hole according to testing. The addition of this drill to a shop's toolbox replaces the demanding and time-consuming process of plunge EDM to establish a starter hole. This is especially true when a plate requires many starter holes, where they can be prepared on a standard machining center to shorten process times with no need to exchange tools.
With this drill, holes with a length/diameter ratio of up to 80x diameter are possible in the range of 0.25mm-1.50mm, in steps of 0.1mm for hole depths up to 20/40/60/80x diameter. A centering/pilot hole of 2x diameter is recommended to begin the process, with the deep-hole drill following with a peck-cycle until the hole is completed.
The Sphinx deep-hole microdrill has a flute- and cutting-edge geometry adapted to this difficult application. Taking in to consideration wear and tear, the drill is constructed of the appropriate high-quality carbide and optimum abrasion-resistant coating for drilling starting holes in high-strength alloyed tool steels.
Testing and development of this drill by BIG Kaiser's Swiss partner, Sphinx, was done in cooperation with clients specializing in moldmaking.
Process that vaporizes conductive materials by controlled application of pulsed electrical current that flows between a workpiece and electrode (tool) in a dielectric fluid. Permits machining shapes to tight accuracies without the internal stresses conventional machining often generates. Useful in diemaking.
Group of alloy steels which, after proper heat treatment, provide the combination of properties required for cutting tool and die applications. The American Iron and Steel Institute divides tool steels into six major categories: water hardening, shock resisting, cold work, hot work, special purpose and high speed.
Process similar to ram electrical-discharge machining except a small-diameter copper or brass wire is used as a traveling electrode. Usually used in conjunction with a CNC and only works when a part is to be cut completely through. A common analogy is wire electrical-discharge machining is like an ultraprecise, electrical, contour-sawing operation.
As opposed to measuring, printing a label and punching the data into the control, SPI prints a tool label with a QR code at the presetter that’s then read by the SPI module at the machine control. The system can also be configured to send measurements directly into the tool NC’s offset table.
The Nirox geometry has a degressive helix angle equal to 30 degrees at the point and is designed for accurate and precise hole location up to 9xD. A modern, TiAlSiN based coating allows for enhanced chip and coolant evacuation in difficult to machine and adhesive materials, such as titanium,…
Due to the small sizes of these boring heads, the digital display will no longer be present on the head itself, rather the adjustment value will be shown on a separate mobile device or tablet that has the BIG KAISER App installed. Once connected to the head, the App also can be used to set the…
The EWA68 boring head has a travel range of .866” on diameter, and with the smallest insert holder, it covers the range of Ø2.677-3.543”. This means that similar-sized bores on the same part could be produced with a single boring head. With the addition of two larger insert holders, the range can…
Chamfering the entry and exit of 0.80mm to 6.00mm holes can be a tedious, time-consuming process. The Noventa from Sphinx can transform this process using an innovative geometry that improves cycle time, tool life and surface quality.
The HDC jet-through type holders are ideal for high-precision 5-axis machining with maximum RPM of 35,000 and clamping range of ¼” to ½” and fit nearly any application in the automotive, aerospace, medical, and die and mold industries.
The exclusive FLM 3D chip-breaker design is used on PCD-tipped inserts ideal for finishing of aluminum components, where traditional flat-top inserts may produce a large continuous nest of chips that is difficult to remove from the bore and/or tool, even with high-pressure coolant. Three different…
BIG KAISER Precision Tooling is adding more than 30 pressed-geometry carbide inserts for its tools. The new insert design is the result of extensive research and testing.
In order to offer more flexibility to customers, BIG KAISER has moved production of its CAT50 milling adapters to the U.S. The product performance and design will not change, but the move allows for more variation and faster delivery of special lengths for specific applications.
BIG KAISER has two powerful accessories crafted to improve in-process efficiency: ChipFans and T-slot covers. When used together with a machine that delivers on speed and accuracy, these accessories help machines reach maximum levels of productivity—even during downtime.
