Ypsotec celebrates 100 years with Tornos

On its 100th anniversary, Grenchen, Switzerland-based Ypsotec, which also has a facility in Tábor, Czech Republic, decided to take its next step towards the future and enter the field of multi-spindle turning technology, choosing a Tornos MultiSwiss 6×16.

An urgent order for 1,300,000 pieces by one of Ypsotec’s customers prompted the company to rethink its operation. First, Ypsotec managers had planned to outsource production to China for financial reasons, but understood they had to invest in new technologies to remain competitive. The company thus had the impetus to break new ground and the MultiSwiss entered the stage.
According to COO Piero Tschanz, the targets set were difficult to achieve with the company’s existing single spindle lathes: “We had to increase our productivity. At the same time, we wanted to avoid structural measures such as a plant extension. Multi-spindle technology quickly came to the fore. After initial analysis, the Tornos MultiSwiss soon turned out to be a solution that aroused our interest.”
As far as ergonomics are concerned, the machine boasts various attributes, including integrated peripherals and good access to important areas. To facilitate work set-ups, Ypsotec is banking on Göltenbodt quick-change toolholders.
“To date, the machine has proved to be a reliable partner and we are fully satisfied with the result,” says Tschanz. “It was very easy for our employees to get accustomed with the new technology and the significant advantages of the machine features in terms of floor space, as well as higher productivity. The hydrostatic bearings on the machine offer distinct benefits with regards to tool life and surface finish.”

High-specification universal lathe

The CTX 2500|700 universal turning machine has been unveiled by DMG Mori. Designed for machining components up to 366 mm in diameter from billet, or 76 mm from bar, and to a maximum length of 705 mm, the machine is the first in the company’s range that allows users to turn grooves up to 12 mm wide in CK45 steel and drill holes to 80 mm diameter.
DMG Mori’s CTX 2500|700 combines the rigid machine bed and box guideway configuration of the NLX 2500|700, of which more than 10,000 have been sold, with the VDI turret and Siemens 840D Solutionline control from the CTX beta 800. DMG Mori’s proprietary app-based control and operation interface, CELOS, is included.

Precision and surface quality derive from the thermo-stability of the lathe, which has a spiral oil jacket around the spindle to control temperature and coolant recirculation through the cast bed. A linear scale with a standard resolution of 0.01 µm is fitted in the X axis for positional feedback. Furthermore, rapid traverse of 30 m/min in the linear axes ensures short idle times, while a Y axis may be specified for turn-milling work.
The TurnMaster 4000 rpm main spindle with 26 kW of power and 525 Nm torque (or optional 3500 rpm, 30 kW, 1194 Nm version) is opposed by an 11 kW, 7000 rpm, 70 Nm (or 32 kW, 5000 rpm, 360 Nm) counter spindle. A 6000 rpm, 32 Nm cooled-disc turret with VDI 40 interface is offered as standard, while an 85 Nm TorqueDrive and a 12,000 rpm SpeedDrive are available.

LNS keeps developing e-Connect

The LNS Group says that it is implementing e-Connect solutions to integrate its products, particularly barfeeds, into customer ERP and MES systems. “This will allow LNS customers to get full machining transparency at a glance, including the workload of each machine, cycle times and expected production completion,” explains Carlos Muniz, global product manager barfeed at the LNS Group.

LNS has been pushing innovation in the field of connectivity for more than 10 years. Together with major machine manufacturers, the connection between the peripheral and the machine tool was developed. A second major innovation was the connection between the LNS product and the humans controlling it. Monitoring production remotely from mobile devices saves time by knowing when the machining process will stop for a changeover, thus anticipating downtime in production planning. Thanks to e-mail or GSM notifications, overall production processes are more efficient. Additionally, the connection to internal or external technical support ensures downtime reduction.
While the e-Connect solutions to the machine and people are essential, another major step is the integration into customer ERP, MES and quality control operations.
“Until now, such systems and the machines were not efficiently connected, missing transparency,” says Muniz. “LNS is developing software drivers that will gather relevant information from the peripheral and, through middleware, feed it to applications or systems such as ERP, MES or quality control. These solutions are tailor-made for each customer software platform. The real-time monitoring of all processes will help clients to save time and resources.”

Heavy-duty turning centres lighten the load

Now available in the UK and Ireland from official importer, sales distributor and sales agent, TDT Technology, is the Feeler range of FTC turning centres and slant-bed CNC turning centres. Aimed at machine shops tasked with heavy-duty machining operations, the machines are designed to offer a competitive cost-to-performance ratio.

The Feeler FTC range comprises three models, the FTC-10, FTC-20 and FTC-30. Between them, the machines cover a swing-over-bed of 520 to 600 mm diameter, a standard turning diameter of 180 to 310 mm, a maximum turning diameter of 240 to 450 mm, and a maximum turning length of 255 to 621 mm. All three feature a spindle equipped with precision, dual-direction, angular-contact thrust ball bearings, while a special heat-dissipation headstock design eliminates elevated temperatures from the spindle bearings, prolonging life and promoting reliability.
TDT says that machines in the Feeler FTC series of slant-bed CNC turning centres are designed for rigidity, efficiency and versatility. Kicking off the range is the FTC-300, which features a 6000 rpm spindle, 6” chuck and 52 mm diameter bar capacity. Moving up, the FTC-350, 350L, 350XL, 350LY (Y axis) and 350SLY (twin spindle) offer a 4500 rpm spindle, 8” chuck and 52 mm diameter bar capacity (66 mm option). All feature a 30° slant bed.
For an even more robust structure, the FTC-450 and 450MC (C axis and driven tools) provide a 45° slant bed, a maximum turning diameter of 450 mm and a maximum turning length of 650 mm. Finally, for the range’s highest power and rigidity, the FTC-640 and 640L again feature a 45° slant bed, which is matched with a 15” hydraulic chuck, 117.5 mm bar capacity, 22/26 kW spindle motor and A2-11 heavy-duty spindle.

Latest Y-axis, sub-spindle turning centre

The next-generation Y-axis, sub-spindle Doosan Puma 2600SY Mk II turning centre series is now available from Mills CNC. Although the new machines are equipped with a 10” chuck, unlike Puma 2600SY Mk I models, they have a larger 81 mm bar diameter capacity. The machines are also supplied with built-in type spindles (as opposed to belt-driven spindles), which generate less vibration during cutting operations.

Further innovations include six strategically positioned heat sensors that automatically monitor and compensate for any thermal displacement during machining operations. In addition, the spindles feature a reconfigured bearing structure comprising two angular-contact bearings and two taper roller bearings to improve C-axis positional accuracy and spindle runout (less than 6 µm).
The Puma 2600SY Mk II uses high-performance NTN material (as opposed to Turcite) on its box-guideway axes, a move that is said to result in improved and more responsive movement, and reduced wear. Other performance improvements include a revised design of milling turret that incorporates a Curvic coupling piston structure delivering up to 12% additional clamping force; improved durability of the Y-axis carriageway; and a spindle air-purge function that helps prevent chip and coolant ingress.
The machine was exhibited for the first time in the UK at the recent Mills CNC open house, which took place in October.
