BIG KAISER Precision Tooling has released a new closed-loop boring system featuring an intelligent, fully automatic fine boring head. This system, when used in conjunction with in-process measuring systems, can automatically compensate for cutting edge wear, resulting in less scrap, improved accuracy and considerable time savings.
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 be extended up to Ø5.197”.
Integration options for existing machine tools is accomplished with the use of an external industrial PC to handle the machine control communications and EWA boring head adjustment. Newer machine tool controls may be suited to handle the EWA software directly to achieve more seamless integration.
For lower level integration where in-process gaging is not present, a third option for implementation exists where the boring head adjustment is performed through manual data input into a tablet or mobile device that is used to control the boring head movement.
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.
Quality-control approach that monitors work in progress, rather than inspecting parts after the run has been completed. May be done manually on a spot-check basis but often involves automatic sensors that provide 100 percent inspection.
BIG KAISER says its hydraulic chucks for Swiss-type lathes are the first improvement to this technology in more than 30 years. These toolholders use a single wrench, which makes for a quick and easy change of the cutting tools on a gang slide.
BIG KAISER introduces two versions of the C-Centering Cutter, a multifunction cutter capable of spot drilling, centering and chamfering. The C-Centering Cutter is an indexable cutter that uses a specialized insert that can start a hole from a solid piece, something extremely difficult to do. It can…
BIG KAISER presents the Torque Fit, a tightening fixture for collet chucks with an integrated torque measuring system. This device makes it easy to ensure that a collet chuck is correctly tightened.
BIG KAISER Precision Tooling Inc. has added the Dyna Contact to its product offering. The ceramic taper gage allows inspection of machine spindle tapers at a glance.
BIG KAISER announced its new Level Master Wireless, a high-precision device for the leveling of machine tool tables. The Level Master Wireless adds wireless connectivity to enable leveling information to be read from a separate display device, making it easier to ensure that a precision level is…
BIG KAISER’s UNIFLEX system is a 3D zero-point clamping system designed to allow parts with curved surfaces to be held rigidly for various operations and be adjusted to different height requirements. The UNIFLEX system is available in two diameters: 25.4mm and 50mm.
The precision and ruggedness of BIG KAISER boring heads deliver measurable performance advantages, significantly reducing finishing cost and cycle time. This is proven through the development of the EWE digital boring head.
BIG KAISER announces its HDC Straight Shank holder to the market, used for increased versatility. The slim design provides superior balance, concentricity and is suitable for reaching into confined areas.
BIG KAISER introduces the Base Master Red, a high-precision touch sensor that rapidly determines workpiece offsets and tool lengths, and the Base Master Mini, a thin, compact tool offset sensor.
BIG KAISER has introduced the R-Cutter CKB Type, a new modular round chamfering tool. The R-Cutter CKB3 and CKB5 is an ultrahigh-feed front and back radius chamfering mill, which features high rake angles that reduce cutting resistance and minimize burr generation.
