Vapormatt Ltd. is launching a fully integrated modular wet blasting machine for edge honing and surface preparation of all types of round shank and solid cutting tools. The new Oncilla wet blast machine incorporates blast chamber, washing, drying, elutriation tower, control and robot handling units in a single compact, high-performance system.
This creates an extremely cost-effective, simple-to-use machine, which is capable of improving productivity and the finished quality of each tool, in low- and high-volume applications for tungsten carbide and HSS inserts, round shank tools, drills, taps and milling cutters.
The modular design of Oncilla offers customers a range of options, which enables them to select the machine that meets their exacting needs and investment criteria. Combining all processes into a single, self-contained machine eliminates the current need for customers to use multiple machines for tool finishing saving cost, part movement, human intervention, complexity and reduces the overall factory footprint.
The basic machine incorporates a blast chamber and washer dryer. This can be expanded with the addition of an extra blast chamber for different finishes and multiple wash/dry stages including de-ionized wash/dry stage for coating-ready requirements.
The micronozzles are unique in being able to offer exceptionally fine control of the blast pattern, with the laser indexing system ensuring that the edge honing and surface preparation processes begin and finish at precisely the correct point on each tool; this is ideal for edge honing of multiple tool pieces where consistent and accurate profiles are required. Additionally, the micronozzles significantly reduce air and energy consumption by up to 80 percent.
Efficiency is improved still further with the addition of an elutriation tower, continuous slurry concentration monitoring, linked to auto abrasive dosing. These features ensure that only the correct sized abrasive media is recycled back through the process, providing consistent and measured process conditions, resulting in repeatable results, consistent edge quality and minimizes rework or scrap.
Each Oncilla machine incorporates an industry standard colour HMI, providing a simple to use, menu-driven interface, with the option of remote monitoring, process batch recording and programming; using MES to take advantage of the industry 4.0 opportunities. Oncilla can be used with tools up to 30mm in diameter and 303mm in length.

- abrasive
abrasive
Substance used for grinding, honing, lapping, superfinishing and polishing. Examples include garnet, emery, corundum, silicon carbide, cubic boron nitride and diamond in various grit sizes.
- gang cutting ( milling)
gang cutting ( milling)
Machining with several cutters mounted on a single arbor, generally for simultaneous cutting.
- high-speed steels ( HSS)
high-speed steels ( HSS)
Available in two major types: tungsten high-speed steels (designated by letter T having tungsten as the principal alloying element) and molybdenum high-speed steels (designated by letter M having molybdenum as the principal alloying element). The type T high-speed steels containing cobalt have higher wear resistance and greater red (hot) hardness, withstanding cutting temperature up to 1,100º F (590º C). The type T steels are used to fabricate metalcutting tools (milling cutters, drills, reamers and taps), woodworking tools, various types of punches and dies, ball and roller bearings. The type M steels are used for cutting tools and various types of dies.
- milling
milling
Machining operation in which metal or other material is removed by applying power to a rotating cutter. In vertical milling, the cutting tool is mounted vertically on the spindle. In horizontal milling, the cutting tool is mounted horizontally, either directly on the spindle or on an arbor. Horizontal milling is further broken down into conventional milling, where the cutter rotates opposite the direction of feed, or “up” into the workpiece; and climb milling, where the cutter rotates in the direction of feed, or “down” into the workpiece. Milling operations include plane or surface milling, endmilling, facemilling, angle milling, form milling and profiling.
- modular design ( modular construction)
modular design ( modular construction)
Manufacturing of a product in subassemblies that permits fast and simple replacement of defective assemblies and tailoring of the product for different purposes. See interchangeable parts.
- shank
shank
Main body of a tool; the portion of a drill or similar end-held tool that fits into a collet, chuck or similar mounting device.
- tungsten carbide ( WC)
tungsten carbide ( WC)
Intermetallic compound consisting of equal parts, by atomic weight, of tungsten and carbon. Sometimes tungsten carbide is used in reference to the cemented tungsten carbide material with cobalt added and/or with titanium carbide or tantalum carbide added. Thus, the tungsten carbide may be used to refer to pure tungsten carbide as well as co-bonded tungsten carbide, which may or may not contain added titanium carbide and/or tantalum carbide.
