Sliding headstock lathe has platen
configuraton
Some precision turned parts manufacturers prefer their sliding-headstock lathes not to employ turret-mounted tooling, favouring the additional speed and simplicity offered by a normal tool platen.
Some precision turned parts manufacturers prefer their sliding-headstock lathes not to employ turret-mounted tooling, favouring the additional speed and simplicity offered by a conventional tool platen serving the main spindle With these customers in mind, Star has introduced the SR-32J, a platen-configured lathe for turn-milling components from 32mm diameter bar up to 310mm long in a single chucking

Roger Innes of Inro says that he has based his company's rapid growth over the last three years mainly on the purchase of Japanese-built Star CNC lathes through A and S Precision
Bar magazines boost lathe output
Two new bar magazines capable of increasing the productivity of an automatic turning machine by typically 10 percent have been introduced to Britain and Ireland by A and S Precision
Competitively priced compared to other lathes of the same bar capacity, the latest model is described as an early-entry machine.
Nevertheless it offers versatile turn-milling capability.
There is a wealth of tooling in the working area comprising six turning tools in the platen, four forward-facing drilling/tapping stations, eight similar rear-facing stations and a maximum of nine powered tools for both cross- and face-working operations, including off-centre machining of features in both ends of a component.
When any of these tools, all of which move together as a block, are programmed to operate with the main spindle, there are concurrent machining opportunities using the rear-working tools in conjunction with the sub spindle, which is programmable in X and Z.
Fully independent, simultaneous machining at both spindles takes place when the sub spindle presents the parted-off component to four dedicated end-working tools.
Both the main and sub spindles can have 15 degree indexing or a full C-axis.
As with all Star lathes, the power of the spindles and driven tooling is generous, allowing heavy cuts to be taken and so contributing to short cycle times.
The main motor is rated at 7.5kW while that of the sub spindle is 3.7kW, both having 7,000 rev/min maximum speed.
Driven tool power is 1kW and speed is up to 5,000 rev/min.
Other features of this rigidly constructed, 3 tonne machine include absolute encoders for instant resumption of machining after power interruption, centralised oil circulation to all ballscrews to promote machine longevity and accuracy, broken tool detection and sub spindle air blow.
