Sliding-Head Lathe is offered with or without guide bush.
September 2, 2008 -
Sliding-headstock, 7-axis CNC mill-turn centers manufacture simple to medium-complex parts up to 20 mm dia. Available with guide bush, SR-20J suits precision machining of long, slender components as well as short, complex parts. Model SR-20JN, used for complex machining of larger diameter components, does not have guide bush and minimizes material costs. Both machines feature 3.7 kW/10,000 rpm main spindle, 35 m/min linear axis rapids, and C-axis positioning of main/counter spindles.
Mid Entry-Level Sliding-Head Lathe, With or Without Guide Bush
For the manufacture of turned parts up to 20 mm diameter ranging from relatively simple to medium-complex, Star Micronics has introduced two new sliding-headstock, 7-axis CNC mill-turn centres.
The traditional version with guide bush, SR-20J, is suitable for high precision machining of long, slender components, but is equally capable of producing short, complex parts. Almost as capable as the high-end SR-20RIII, the new lathe can be purchased for 15 per cent less. It is therefore ideal for early entry users that expect to progress quickly in their use of the technology.
The absence of a guide bush in the second machine, SR-20JN, results in drastic reductions in material costs, especially when machining short parts approaching the lathe's maximum bar capacity. The headstock is able to grip the material very close to the point of machining, so the remnant is only around a quarter of the bar length that is normally involved when using conventional sliders.
With increasing material costs, the competitively priced Star SR-32JN is the answer to complex machining of larger diameter components and is even more cost effective if expensive material is being processed.
High productivity is delivered by an industry-leading specification that includes a 3.7 kW / 10,000 rpm main spindle, 35 m/min rapids in all linear axes, and C-axis positioning of the main and counter spindles. Both models have an installed weight of 2.2 tonnes, imparting a robustness that allows very high accuracy and surface finish to be achieved. Spindle cooling ensures thermal stability and also contributes to high precision machining.
The working area can accommodate a large number of cutters and the usual six ganged turning tools above the guide bush. They include four front-facing and four rear-facing endworking tools in the main sleeve holder; up to 10 live cross-working stations, some of which may be swapped for more end-working tools or other attachments such as for angle drilling, hobbing or roller burnishing; and an independent, four-spindle back-working unit with live and stationary positions.
Both lathes can be fitted with the latest Minimag 20 bar magazine, which is equipped with a 22 mm pusher for feeding bar of 20 mm diameter without bar end preparation.
