Note: Readers of the Editor’s free email newsle
A twin-pallet, horizontal machining centre, fully configured as a new standard package for high volume production of complex components within a 500 x 350 x 300 mm working envelope, is available in the UK for demonstration at Yuasa Warwick Machinery, sole UK agent for the Japanese manufacturer, Enshu. Designated JE30S, it is a high productivity machine with 1.5g acceleration in all axes, 60 m/min rapids, up to 15 m/min cutting feed rate and a BT30 13,000 rpm spindle motor (20,000 optional) which reaches full speed in just 0.38 sec from a standing start. The incorporation of an armless servo motor driven ATC and the option of broken tool detection inside the magazine contribute to the machine's reliable production capability.

Yuasa points out that for a capital investment of a little over œ110,000, a company can acquire the cell complete with full NC B-axis (as opposed to an indexing rotary table), 30-tool magazine, through-tool coolant, and a comprehensive swarf management system including bed wash, ceiling-mounted coolant nozzles and back wash coolant pumps.

There are no extras to pay for and the machine is ready to run 24/7 immediately following installation, as initial programs will usually have been written by Yuasa applications engineers as part of the sale.

The machine meets Enshu's 5,000 hours mean-time-between-failure reliability standard, as do all the manufacturer's latest models.

Measures have been taken to minimise operational power consumption, which is now 30 per cent lower than for previous machines.

The JE30S is also available in single-pallet version as well as in line-transfer format for production line applications.

The latter has dictated that all axis movements are on the column, supported on recirculating rolling element linear bearings.

Ballscrew expansion compensation is available as an option.

There is a choice of CNC system - either Yaskawa or Fanuc 21 iM.

Value engineering upgrades CNC lathe specification

Following a value engineering exercise carried out by lathe builder's design team, models offer infinitely variable spindle speeds using constant power AC inverter electronic spindle.
Following the resurgence in international demand for its manual centre lathe range and the resulting value engineering exercise carried out by Colchester Lathe design and production engineering team, the Colchester Sales operation is now able to offer the newly developed variable speed Master and Triumph VS centre lathes at GBP 11,950 and GBP 12,750 respectively. Providing outstanding value for money, both machines feature an AC inverter 7.5kW electronic spindle drive giving constant power, through three infinitely variable ranges. There is also a constant surface speed option which gives improved surface finish capability and shortened facing-off cycles.

Each machine uses a heavy duty construction with a wide bed and triangular webs to provide high torsional stiffness and stability.

Slideways are coated with 'Moglice' PTFE low friction linings for longer life and reduced 'stick-slip'.

The Master has a 350mm swing and 650mm between centres capacity with 17 to 3,250 revs/min speed range and No 4 taper tailstock.

Meanwhile, the larger Triumph has a 400mm swing with 1250mm between centres.

Its speed range is between 14 and 2,500 revs/min with a No 5 tailstock taper.

Touchscreen system simplifies electronic lathe use

Touchscreen-programmable machining brings even more user-benefits and upgraded technology to make an electronic lathe the most straightforward and easy-to-use in the world.
Leading British lathe manufacturer, Harrison, has launched the Alpha 350T (Touchscreen) electronic lathe, bringing even more user-benefits and upgraded technology to its highly successful Alpha 'T' range. Hailed as the most straightforward and easy-to-use electronic lathe in the world, the new Alpha 350T has an increased swing of 350mm, compared with the previous entry model (Alpha 330T), and a highly impressive 250 per cent expansion in controller memory. Further advancements include an automatic, three-range, variable-speed headstock, while the 350T's uprated drive train, running on ultra high load-bearing capacity Gamet bearings, substantially increases cutting performance.

The Alpha 350T takes the widely-recognised hallmarks of the popular Alpha T range - affordability, ease of operation and versatility - to a new level of excellence, while retaining its core benefits.

All Harrison Alpha T lathes are designed to appeal to a wide variety of applications and users, for example, sub-contractors, toolrooms, mould and die facilities, Research and Development operations and education/training establishments.

They offer users - especially those wishing to replace traditional centre lathe machinery - the flexibility of both fully automatic cycles and manual operations.

One of the keys to the appeal of the Alpha T range is the menu-driven Fanuc touchscreen control that uses 'shop-floor' symbols and logical step-by-step instructions to access a comprehensive range of functions.

These include: automatic internal and external parallel/taper roughing and finishing box cycles, as well as left- and right-hand single and multistart threads (including Acme, DP and MOD).

Complex contours and repetitive cycles can also be performed, while each tool has its own independent constant surface speed function.

As well as being extremely simple to operate, the new Alpha 350T has another important advantage over its rivals, with all machine controls ergonomically mounted on a single operator's console, so that the operator can see the controls, tools, workpiece and cutting area all in a single line-of- sight.

On-screen self-diagnostic messages in plain language are conveyed instantly to the operator thanks to the Intelligent Help Diagnostic System (IHDS) developed specially by Harrison for lathes such as the Alpha T range.

A separate diagnostic LED array is also incorporated.

With the introduction of the 350T, the full Alpha T model line-up now comprises: Alpha 350T (350mm swing x 650mm bed); Alpha 400T (400mm swing x 1.25m bed); Alpha 460T (460mm swing x 1.5m bed) and Alpha 550T (550mm swing x 2m bed).
