ITC Offers Small Bore Tooling Range

13 January 2015

The extension of the Micro 100 line of boring tools from Industrial Tooling Corporation (ITC) has now noted the launch of the QBB series of solid carbide boring tools for turning centres and the new QBM Series for machining centres.
Manufactured from a micro grain carbide substrate that delivers astounding tool life, the innovative new MicroQuik lines have been created for machining high precision bores from a minimum diameter of 1.27mm for the QBB line and 3mm for the QBM series.

The flexible new system can be adapted to all standard tooling platens for high precision boring on CNC lathes and sliding head turning centres. This is possible on the QBB Line with shank diameters of 12, 16, 20, 22, 25 and 32mm that provide compact dimensions suitable for sliding head turning centres and machines with limited tooling platen capacity as well as larger diameters for heavy duty turning centres.

The overall length of the QBB ranges from 38 to 114mm with a maximum boring depth from 3.8 to 76mm. The boring depths and geometries have been optimised with a number of shank and maximum bore lengths available for each diameter range. This extensive variation has been made available to eliminate deflection and improve surface finishes and precision.
To prevent the sharp edges from breaking, the QBB line is also available with the option of either a 0.08 and 0.13mm corner radius. However, with high pressure through coolant facility, an extremely tough carbide substrate and the option of an AlTiN coating, edge breakages are an uncommon occurrence for this outstanding performer.

These attributes are also apparent in the Micro 100 series of QBM boring tools for machining centres. The QBM line is offered for minimum bore diameters from 3 to 11.7mm and maximum bore depths from 12.7 to 76.2mm. With an overall length of 51, 64, 76, 89, 102 or 114mm, the QBM series is provided with either an 0.08mm or 0.2mm corner radius.
A key innovation behind the MicroQuik series is the unique toolholding collet that works with a 3-point location system to guarantee accuracy, repeatability and tool change speeds beyond the capabilities of alternate products. Regardless of whether the end user is conducting turning or milling operations with the QBB or QBM range, the patented 3-point location system is the envy of all boring tool manufacturers.

The 3-point locking toolholders provide accuracy and concentricity to a tolerance of 12microns centreline repeatability from tool to tool. This is credit to a toolholder design that has a locking screw and locating pin for positioning whilst each carbide tool has a flat surface for coolant to pass through the toolholder and directly to the cutting edge. To support the diverse demands of industry and the numerous machine tool configurations, ITC is supplying the new range with a selection of round or square toolholders.
