Rigid CNC turning centre takes heavier
cuts
The rigid nature of a CNC turning centre and the power available for the driven tooling has enabled a subcontractor to reduce cycle times on many parts by taking heavier cuts.
With a history of manufacturing small turned parts on firstly CAM automatic lathes and then sliding head CNC lathes, Auto Screw Products has for 40 years concentrated solely on this niche sector However, the changing needs of its customer base now has the BTMA member diversifying to deliver parts outside the 32mm diameter scope of its sliding head machines

Two 8-axis turning centres, one with Y-axis movements, have two spindles and its two turrets are positioned above and below the workpiece and can both work at either spindle.
CNC lathe set-up is flexible to meet future needs
Flexible set-up of a fixed head CNC production lathe allows the user to specify the machine - tooling up and down to suit its needs - giving a machine that is flexible to market trends.
And when aiming to meet customer demands for parts up to the 42mm diameter range, the Knowsley, UK-based subcontractor immediately turned to Miyano and its BNJ-42SY turning centre.
Manufacturing components for the automotive, hydraulic, construction and plastics industries, Auto Screw typically produces batches from 500 to 20,000 on its eight Star sliding head lathes.
However, the deviation to slightly larger components set Auto Screw into a search for a larger capacity machine to manufacture small and large batch ranges alike with the added capability of producing increasingly complex parts.

Turning centre added to subcontract facility
Although predominantly a user of CNC sliding head automatics, a machine shop recently purchased a Miyano BNJ-42SY turning centre to increase flexibility and respond to customer needs.
Turning centre raises productivity 30-50%
A twin turret, twin spindle turning centre has helped an UK aerospace subcontractor to improve its machining productivity by an average of 30%, and up to a staggering 50% on many components.
As Auto Screw managing director Mike Worsley commented: "We manufacture a wide variety of components from mild steels, brass and aluminium through to stainless steels and titanium; so we needed an accurate machine with a high level of repeatability and rigidity - and the Miyano has met all these needs comfortably.
Since installing the machine in January we have not only had the scope to meet the increasingly diverse needs of our customers but we have also won a considerable amount of new business." As a company intent on inward investment with over GBP 1 million spent on machine tools in three years, the 7-Axis Miyano BNJ-42SY is the latest and the next logical step in the company's development.
A major factor in the purchase of the Miyano was the winning of a new contract for a spindle component for the automotive industry.
The 700mm long 25mm diameter part that is manufactured in batches of 10,000 would have proved a costly project if manufactured on the sliding head lathes.
The sliding head lathes could only produce three parts of the 316 stainless steel part per bar length, however the Miyano BNJ-42SY could produce four parts due to the shorter bar end produced by the Miyano.
With the high cost of stainless steel, this material and productivity saving on the Miyano reduced the costs of the project considerably.
"The rigid nature of the Miyano and the power available for the driven tooling has enabled us to reduce cycle times on many parts by allowing us to take heavier cuts.
Not only have we reduced cycle times on some parts but we have improved surface finishes due to the robust build of the machine.
An increasing amount of work suits the Miyano as the high pressure coolant is particularly useful when deep hole drilling is required," continued Worsley.
The new investment has enabled the 23 employee subcontractor to compete for work previously outside the scope of its machining capabilities.
And now new doors are opening, the company is planning to add to its capacity range.
"The Miyano is the perfect compliment to our current machine capacity and since the installation in January we have received new business from current as well as new customers due to the extended capacity and capability levels.
Enquiries for larger diameter work continue to come in, and for this reason we are likely to make our next machine purchase a Miyano BNE-51SY with 51mm bar capacity.
Since installation the BNJ-42SY machine has performed exceptionally well and the support from Miyano and the local agent Bewley and Co has been excellent," concluded Worsley.
