The new program is offered in both internal and external styles. Internal thru style tools are offered in sizes from 0.187-0.501 inch (4.75-12.73mm) diameter, and bottoming style for diameters larger than 0.246 inch (6.25mm). External tools are offered in sizes from 0.054-0.254 inch (1.37-6.45mm) diameter in bottoming style.

NOV stays ahead of the competition
January 24th, 2013
Year 2012 saw the arrival in National Oilwell Varco’s (NOV) Jebil Ali plant, a Doosan DBC 130L horizontal boring machine equipped with Cogsdill (www.cogsdill.co.uk) ZX 300 facing/contouring head, and a modular tooling package to enable a range of boring operations to be completed. The DBC 130L along with two Puma 700 LM horizontal turning centres form part of a full turnkey package supplied by Passtech Machine Tools ME Ltd (www.passtech.co.uk).
NOV Dubai has established itself as a centre of excellence within the National Oilwell Varco family and has become the blueprint for other NOV plants worldwide due to the modern methods or manufacture deployed along with prudent engineering management which culminate in output of the highest quality while achieving major cost savings throughout the manufacturing process. Passtech Machine Tools ME Ltd have assisted NOV in achieving this impressive end result through knowledge share and support in conjunction with the product knowledge and experience of NOV’s experienced engineering management team.
Utilisation of the Cogsdill facing head equipment along with visionary programming of the HBM machine has allowed NOV to slash previous production times and eliminate scrap through a robust and sustainable production process. The Doosan DBC range of CNC horizontal boring machines have already established themselves throughout the GCC states major CNC machine shops and this machines flexibility is being enhanced further by Cogsdill products throughout the regions.
Contouring head basics
NOV utilises the Cogsdill ZX contouring head to the maximum. Contouring heads transform a horizontal boring mill’s W-axis quill motion into radial cutting edge motion, David Grundy, General Manager of NOV explains. “Inside each tool is an actuator shaft with an inclined key that precisely mates with a slot in a tool slide. Quill extension pushes the actuator shaft and causes the tool slide to move outward, increasing the diameter of the rotating cutting edge. Quill retraction decreases the cutting diameter.”
Combining a machine’s quill motion with its table feed allows a single head to perform many operations. Facing can be performed by moving the quill (and thus, the cutting edge) while the machine’s table remains stationary. Keeping the quill stationary and moving the table enables boring and turning operations. Combined quill and table movements can generate features such as radii, chamfers, tapers and complex ID or OD contours.
Programming a contouring head is simply a matter of coordinating the machine’s W and Z axes to guide the cutting edge. Depending on the contouring head model, though, the ratio of quill stroke to radial cutting edge stroke might not be 1:1, this must considered when creating part programs. For example, some ZX heads have a 2:1 ratio of quill stroke to cutting edge stroke.
Machine-specific bonnets allow a single head to be used across a variety of boring mill brands. The bonnet bolts to a mill’s outer spindle (the outer spindle provides the rotation for the cutter). The contouring head quickly installs into the bonnet and is secured via locking cam pins. Other ZX heads, including modular boring tools and valve seat tools, can also be installed on a mill’s bonnet.

SEDT – Smooth Edge Deburring Tool – is a universal tool designed primarily for the deburring of holes in both angled and elliptical surfaces while also applicable to holes in flat surfaces. SEDT is the perfect addition to our “one pass solution to your hole-deburring needs” family of tools which include our Burraway and Burr-Off product lines for deburring both the front and back side of most holes. While utilizing the same working principal as both Burraway and Burr-Off, SEDT has some unique features and benefits.
• SEDT deburrs holes in flat surfaces, angled surfaces, and elliptical surfaces.
• SEDT product size range covers holes from 5/32 to 1/2 inch in 1/64 inch increments and holes from 4.0 to 12.5mm in 0.5mm increments.
• SEDT utilizes only 5 cutters to cover the entire range, one each for the 5 tool series.
• SEDT cutters are carbide with TiN coating as standard.
• SEDT cutters are crowned and polished on the top surface to insure that the cutter will not mar the inside surface of the hole.
• SEDT cutters are replaceable without the need of special tools.
• SEDT cutting load pressure is adjustable without having to remove the tool from the machine.
• SEDT tools are designed with metric hardware and come with hex wrenches for adjustment and blade replacement.
Refer to our new SEDT – Smooth Edge Deburring Tool – catalog #150 for complete tool series specifications, operating parameters, and blade replacement and tool adjustment information. View our new catalog online at www.cogsdill.com
Burr-Off Tools
April 7th, 2011
No longer supplied with tension adjustment mechanism
Cogsdill Tool Products, Inc. announces that the tension adjustment mechanism that was previously supplied on Burr-Off tools size CP-10 and larger will no longer be supplied as a standard feature. After extensive research it was determined that most of our Deburring customers were not utilizing this feature and discarding this screw and nut mechanism used to adjust the tool tension to control the amount of hole edge break. Also many customers are requesting a customized slot length to accomplish this same task. This change will go into effect immediately with newly manufactured Burr-Off tools.
For those customers that may still require this feature, the following screw thread sizes for the screw and nut tension adjustment mechanism are supplied for your reference:
CP-10 thru CP-13 #0-80×1/4
CP-14 thru CP-23 #2-56×3/8
CP-24 thru CP-27 #5-40×1/2
CP-28 thru CP-31 #8-32×5/8
CP-32 thru CP-35 #10-32×5/8
CP-36 thru CP-40 ¼-28×3/4
The tension adjustment mechanism will be available for sale. Please specify “Tension adjustment mechanism for CP-__”.
