Citizen introduces integrated laser cutting breakthrough as part of CNC sliding head cycle

Thursday, July 27th, 2017

Citizen Machinery’s fully integrated laser processing into the turn-milling cycle of its Cincom CNC sliding head turn-mill centres enables near endless possibilities for the creation of geometric shapes or precision holes into solid bar material which has been pre-drilled within the same production cycle or directly into tubular bar material.

The development opens the metal cutting production process to producing burr-free holes as small as 0.2 mm diameter, produce features such as spiral cuts with 0.025 mm kerf width and maintain consistent and accurate radii less than 0.1 mm in corners of slots without any risk of tool wear or breakage. These can also be produced at a far faster rate than can be achieved by a separate EDM process, for instance.

The Citizen Cincom breakthrough opens new design concepts, in particular in sectors such as medical, electronic and micro industries where the speedy, accurate, highly flexible and reliable Citizen CNC sliding head machine can be integrated with the gains and advantages of non-contact laser operations. Laser cutting can offer quick and accurate ‘swarfless’ cutting, the minimisation of any chance of material deflection due to cutting force reaction and the highly precise production of special shapes and forms.

LFV TECHNOLOGY WINS FOR SWARF CONTROL OF MACHINING PLASTICS COMPONENTS

Monday, May 15th, 2017

Plastic Turned Parts (PTP) was the first company in the UK to install a Citizen CNC sliding head turn-mill centre incorporating the patented Low Frequency Vibration (LFV) machining technology and as a result has been able to totally eliminate swarf control problems in producing thousands of plastics components.

Said Managing Director Jonathan Newis: “For us, the development of LFV has transformed our turn-milling operations so we can now confidently progress the business and operate the Citizen bar machine from pressing the start button rather than having to continually interrupt the cycle to clear troublesome birds nesting of plastics swarf.”

Mr Newis describes LFV as being especially effective on deep hole drilling and said: “We have totally eliminated any clogging of drill flutes. Previously we often had to set the machines with two or even three drills due to swarfing problems but we can now go straight to depth with a single tool and the flutes are completely clean.”

citizen-showroom

Citizen Machinery has replaced its showroom lighting with the latest Waldmann Lighting Acaneo Highbay Luminaire LED system that not only provides glare-free lighting across the whole working area but also has enabled the previous nine 400 watt units to be replaced with energy saving 160 watt LEDs. In addition, the new system will reduce maintenance costs with an LED life of 60,000 hours as against the previous mercury based system which involved annual replacement.

Said Managing Director Geoff Bryant: “Waldmann is based about a mile from our offices in Bushey and is already a supplier to Citizen for its machine lighting. The company had taken a stand at MACH 2016 at the NEC in April when I recognised the name as I walked past. This coincided with our plans to upgrade our air conditioning and lighting at our headquarters and led to quotations and order placement very soon cheap cymbalta prescription after the show.”

No strings attached

Thursday, October 27th, 2016

A new level of cutting technology was launched by Citizen at its recent open house that is reported to increase the performance, levels of surface finish and significantly improve chip control.

The new machining development was demonstrated on the latest Citizen Cincom L20-VIII CNC sliding head turn/mill centre, is fully programmable and can be applied to processes including turning, facing, drilling and even thread cutting operations.

The patented process of Low Frequency Vibration cutting (LFV) took some three years to develop and was amongst the latest concepts unveiled and demonstrated to the 3,000 visitors from around the world at last year’s CFA85 Innovative Manufacturing Event staged at Citizen’s Japanese headquarters. This technology has also been recently demonstrated this autumn by Citizen at AMB in Stuttgart and BiMu in Milan where high levels of interest in the potential for its application were shown by visitors.

Citizen takes 2 million pounds worth of orders

Citizen Machinery’s launch of its Low Frequency Vibration (LFV) cutting technology plus integrated laser cutting on two of its Citizen CNC sliding head turn-mill centres drew almost 300 potential customers and visitors to its three-day Open House where 18 machines from the Citizen and Miyano fixed head ranges were being demonstrated.

As a result of the event, over £2 million of machine tool future investment orders were placed by visitors to the Bushey headquarters with some travelling from as far away as Scotland and Ireland and internationally from Denmark, Sweden, Germany and Portugal.

Said Sales Director Darren Wilkins: “We have often demonstrated how new machine tool technology reduces non-cutting time. However, this was the first time we have radically broken new ground in changing the machining process and the cutting of material. It has certainly created interest with us taking orders for machines with integrated LFV technology due for delivery in January and considerable longer term pre-order intent.”

Visitors were also able to view live demonstrations on some of their own components being manufactured on the latest Cincom L20-VIII using ‘programmable’ LFV technology to control chip removal on materials that are normally challenging to manage even with high buy generic cymbalta canada pressure coolant. Said Mr Wilkins: “Most visitors were able to appreciate the opportunity to remove or reduce the need for high pressure coolant as well as the potential advantage to increase productivity and reduce the cost of expensive consumable tooling.”

Added Mr Wilkins: “Many sliding head users immediately recognised the advantage of LFV in greatly improving the removal of swarf from the machining area and its help to reduce downtime as a result of damaged or worn tooling. As the vast majority of our customers run Citizen machines unattended they therefore welcomed the opportunity to extend their production capability and were enthusiastic over the ability to switch, as required, to suit the application between the ‘programmable’ chip control development and a conventional non-LFV machine.”

Luke Dealhoy of Gedore Torque drew the top prize of an Orange mountain bike fitted with high specification Hope equipment produced on both Citizen and Miyano machines installed in its factory in Bartnoldswick, Lancs. To qualify for the draw Mr Dealhoy remembered to bring along his token from his visit in April to the Citizen stand during MACH 2016 at the NEC. Meanwhile, Simon Lilley of S. Lilley & Son is now the proud owner of a new Citizen Eco Drive watch from the visitors card draw at the event.


Citizen Machinery develops low frequency vibration cutting technology with Open House demonstration

Monday, October 24th, 2016

lfv_postA totally new level of cutting technology is due to be launched by Citizen at its Open House between 11 and 13 October that is able to increase the performance, levels of surface finish and significantly improve chip control. This breakthrough in machining development will be demonstrated on the latest Citizen Cincom L20-VIII CNC sliding head turn-mill centre, is fully programmable and can be applied to processes including turning, facing, drilling and even thread cutting operations.

The patented process of Low Frequency Vibration cutting (LFV) took some three years to develop and was amongst the latest concepts unveiled and demonstrated to the 3,000 visitors from around the world at last year’s CFA85 Innovative Manufacturing Event staged at Citizen’s Japanese headquarters. This technology has also been recently demonstrated this autumn by Citizen at the European exhibitions of AMB in Stuttgart and BiMU in Milan where high levels of interest in the potential for its application were shown by visitors.

Cutting trials both in Japan and Europe have already demonstrated significant improvements to cutting efficiency, not only on exotic materials but also, on ‘difficult to chip’ ferrous and non-ferrous materials. In certain cases the need for integrated high pressure coolant systems and fume extraction has been reduced or even replaced, thus creating additional savings from reduced power consumption and improved set up times.

When LFV has been applied, it has led to forecasts that the productivity can be revolutionised when machining malleable materials, for instance, and especially plastics and copper which pose machinists with a constant challenge to maintain effective chip control.
