Bending Capacity Added to Remove Bottleneck
01 Jun 2004
The recent installation of a highly productive CNC turret punch press at subcontract sheet metalworking and fabricating company, Cirrus Engineered Products, Broadstairs, caused a shortfall in capacity for subsequent bending operations. To address this, the company has made a further investment in a pair of Guifil computer-controlled press brakes.
David Mitchell, managing director of family-owned Cirrus commented: "Our new punch press brought an immediate significant improvement in speed, accuracy and reliability, plus it increased the size of sheet that we could process. For a time we used it in tandem with a pair of manually operated Guifil press brakes; but an enquiry that would have necessitated processing longer sections than hitherto focussed our attention on upgrading to CNC bending. As a result our productivity has improved immensely."
Based in Kent UK, Cirrus specialise in high quality sheet metalwork and CNC punching that has full CADCAM capability using state-of-the-art offline programming.
The company has all the necessary facilities for high quality production and prototyping of all sheet metalwork and CNC punching applications. Professional MIG and TIG welding is also undertaken.
Cirrus handles a wide variety of sheet metal fabrication work drawn from many industry sectors. This has included components for amusement machines, gas fires and architectural metalwork, notably high specification window framing for prestige projects.
Much of this is contract-based, repeat business but the company is also geared up for one-offs and prototypes.
The new 1.5 m x 30 tonne upstroking machine and a 3.0 m x 110 tonne downstroking model, were supplied by sole UK agent for the Portuguese manufacturer, Press & Shear Machinery, Tamworth.
For Cirrus, the key benefit arising from CNC bending is the ability to completely fold a component to completion in one sequence, rather than in a series of separate set-ups. This also allows any necessary corrections to be identified at the start and distributed over the entire bending sequence.
"We've been very pleased with both press brakes, " Mr Mitchell concluded.
"They have certainly transformed our bending capabilities. Productivity is the obvious gain but overall quality has improved without a conscious effort. It is also the case that work that would previously have presented a challenge can now be done more routinely.
That's an important benefit for our customers as well as for us."
