Debunking concerns about finishing tools used in CNC applications

With new advances in abrasive technology, machining center operators are able to complete surface finishing simultaneously with other machining operations, to speed cycle times, improve quality and save on off-line finishing time and costs. The abrasive finishing tools can be easily integrated into CNC machines carousels or tool holding systems.

3/8 NPT FullStream Liquid Atomizing Spray Nozzle

With FullStream nozzles, the liquid is supplied directly into the body of the nozzle creating a swirling action within a vortex chamber. This vortex produces the desired spray pattern when the machined nozzle breaks the liquid surface tension, and exits the orifice in a round, controlled spray angle.n

Mounted Stone Kit

The stones have a distinct pink color due to their components and can be used on a variety of steels and alloys where sharp cutting action is essential. The characteristics of the pink abrasive grain make the stones exceptionally durable while providing cooler cutting. Each kit contains a wide variety of stone sizes for use on both large and small workpieces.

Color-Coding Added to Brushes for Stainless Steel

The color-coding helps stop cross-contamination in operations working with both carbon and stainless steel by making it easy to identify the correct wire brush. The color-coding is a visual change to an existing product line — there will be no change to the performance of the stainless steel offering. Part numbers and pricing will also remain the same.

WTX High-Feed Drill

The innovative pyramid geometry of the WTX ensures extremely aggressive and precise drilling performance. In fact, the WTX achieves positioning accuracy of 0.03 mm and excellent centering properties. Higher levels of drilling quality, hole tolerance, surface finish, and positioning accuracy increase component quality, to the extent that there is no need for potential reworking. Furthermore, low burr formation when entering and exiting the hole eliminates the need for time-consuming subsequent deburring.

Efficient treatment for wastewater compliance

The metal machining, fabrciation and finishing industries must meet EPA and local wastewater requirements for effluent. Under the Clean Water Act, the EPA has identified 65 pollutants and classes of pollutants as "toxic pollutants," of which 126 specific substances have been designated "priority" toxic pollutants. Failing to meet these requirements can result in severe fines that quickly escalate.

Surface Finish on A36 Steel

ProvenCut recipe 586 struck a wonderful balance, machining a piece free of chatter and yielding an extraordinary finish using a YG-1 V7 PlusA six-flute endmill held in a Lyndex-Nikken SK16 collet holder. The 2D contour finishing operation was programmed with Autodesk Fusion 360 and run at 210 m/min. (690 sfm) at 0.015 mm feed per tooth (0.0006" feed per tooth) with a 0.203 mm (0.008") radial DOC and 63.5 mm axial DOC.
