Turning inserts cut valve body machining
times
Oil and gas industries supplier has carried out cutting tool insert trials on on SS and NF alloy valve bodies and turned bearing housings and has realised time savings exceeding 10 min.
Trials using cutting tools supplied by TaeguTec at Denholm Rees and O'Donnell, a Liverpool, UK-based supplier of precision parts to the oil and gas sector, have offered cycle time savings in excess of 10 minutes on components manufactured from inconel 718 Formed 75 years ago to serve local shipyards, Denholm Rees and O'Donnell has since diversified successfully into a number of other industries, at the core of which is the oil and gas sector

Lower price ceramic inserts are pressed to size
What is believed to be a ground-breaking new product - 'As Pressed' ready-sized ceramic inserts - will be launched at MACH 2002. The inserts are some 20% lower in cost and life increased by 30%.
Pressed ceramic inserts up cutting performance
To be launched at MACH 2002 is a product that will revolutionise the metal cutting industry's use of ceramic inserts for turning and grooving, dramati- cally improving tool-life and cutting speeds.
The ISO9001:2000 certified company machines parts in batches up to 20-off from materials that include super duplex, stainless steel alloys, hastelloy, titanium and inconel 718.
This latter material was recently the subject of extensive cutting insert trials on valve bodies and turned bearing housings.
"We have worked with TaeguTec for the past seven years, purchasing cutting tools through HB Tools, TaeguTec's regional distributor," explained works director Ian Johns.

Dense carbides mill cast iron at 45,000 rev/min
Specifically designed for mould and die toolmakers and high speed machining applications, the use of extra dense, sub-micron grade carbides in end mills enable cast iron milling at 45,000 rev/min.
Ceramic inserts turn tough materials faster
Ceramic turning inserts allows high nickel content alloys, such as Inconel 718 and Waspaloy, to be turned at speeds of up to 350m/min - six times faster than standard ceramic tooling.
Exceptionally strong holder allows bigger feeds
Providing exceptionally strong clamping force, a turning toolholder is ideal for high feed machining enabling feeds to be increased greatly when conducting continuous or interrupted cutting.
"In fact I was invited to TaeguTec Korea last November and was extremely impressed with the facility and the company's capabilities, set up and product range.
I knew TaeguTec had some new products to help improve our inconel 718 cycle times, so I was excited to see the outcome." The first trial, involving an inconel 718 valve body turned on a Daewoo Puma 480, pitched a TaeguTec TDR cutter featuring an SPMG insert (TT9030 grade) against the company's existing preferred choice - a conventional HSS drill.
At 58mm depth of cut, engineers were able to increase surface speed from 6 to 55m/min with a spindle speed from 90 to 450 rev/min, reducing total part cycle time from 15 to 1.6 min.
The second trial, conducted on the same machine, involved turning an inconel 718 bearing housing using a TaeguTec cutter with a ceramic RNGN insert (AS20 grade).
Here, surface speed was increased from 50 to 200m/min producing a cycle time saving of over 10 min per component against the cutter deployed previously by Denholm Rees and O'Donnell.
"We understand that many of our customers have moved away from the production of traditional components in-house, to focus on their core competency," said Johns.
"Therefore it is our responsibility to ensure we optimise our production processes and offer the most cost effective service without compromising quality.
These trials demonstrate TaeguTec's exceptional product quality and technical support." Today Denholm Rees and O'Donnell employs 55 people at the firm's 30,000ft2 facility in Liverpool along with a further 32 at a sister company in Stoke on Trent - CE Edwards (Engineers).
Approximately 70% of the company's machining activities are turning processes on large components up to 2m in diameter.
However, machining is just one string to the company's bow.
In reality, Denholm Rees and O'Donnell offers a single source service, providing everything from pre-production design and development resources through to post-production finishing and installation.
Therefore, if so required, Denholm Rees and O'Donnell can accept commissions for complete assemblies and manage projects through to completion.
This flexible approach, coupled with the company's policy of continuous investment is allowing Denholm Rees and O'Donnell to offer real value for money in a fiercely competitive industry.
"We pride ourselves on offering a high quality, cost effective service to our customers, and we demand a similar level of professional support from our suppliers," concluded Johns.
"Over the past seven years TaeguTec has proved itself extremely capable of matching our demands for progress through continuous optimisation of production processes.".
