Mazak recently introduced the new UN Series of high-speed vertical and horizontal machining centers, the UN-600/30V and UN-600/30H respectively, to meet the productivity, reliability, maintenance and automation requirements of the growing automotive manufacturing industry.

Designed for the mass production of automotive components, these #30 taper machines feature a small footprint as indicated by their UN (ultra-narrow) designation. The UN Series machines are automation-friendly, allowing multiple machines to be placed together and tended by one robot.

The width of the UN-600/30V vertical machining center is 27.4" and can accommodate a maximum workpiece diameter of approximately 23.6". This is made possible by interpolating the machine C- and Y- axes for the X-axis, which is programmed in the same way as a conventional machine X-axis. The UN-600/30V offers 20-tool storage capability.

The UN-600/30H horizontal machining center has the same maximum workpiece diameter of 23.6". This is achieved by the machine having a compound X-axis, whereby half of the axis stroke is on the machine table and the other half is on the machine column. The UN-600/30H features 30-tool storage capability.

New integral spindle/motors are used for faster acceleration/deceleration to provide high productivity. The UN Series machines feature high-speed 20,000 rpm machine spindles that accelerate to top speeds in .55 seconds and perform synchronized tapping at 8,000 rpm.

The machines’ linear guides and ball screws are isolated from the machining area to prevent problems caused by the accumulation of machined chips. Additionally, areas of the machine that require frequent access, such as the lubrication and air inlets, are centrally located for convenient maintenance.

The hallmark of the MA-12500HW is its ability to provide a balance of speed and cutting power for machining difficult-to-machine materials, cast iron and aluminum alloys. This makes it suited for large part aerospace machining.

The W-axis allows for a longer tool stroke to machine complex, difficult to reach part features. It has a maximum tool length of 1,100 mm. At IMTS 2016, the MA-12500HW will be shown with the new W-axis option and in skeleton form. It will feature a cutting simulation of a steel construction frame.

Built on an integral bed and base and designed with reinforcing ribs for increased stability and load carrying capacity, the MA-12500H incorporates Okuma’s proprietary Thermo-Friendly Concept to achieve thermal stability and accuracy.

Standardly-equipped with a 50 taper 6,000 rpm, 60/50 horsepower spindle, it is also available with either a 12,000 rpm wide range spindle or 4,500 rpm heavy duty spindle. Other features include:

Maximum load capacity of 11,000 pounds
Rapid traverse (X, Y, Z) of 1,653 ipm
Maximum part size: 78.72” diameter x 58.07” high
Axis travels: X-86.61”, Y-58.07”, Z-64.96”
.001 degree B-axis rotary table
49.21” square pallet
Parallel-type 2 pallet APC
81 tool matrix ATC standard, up to 171 tool matrix optional

Sunnen Automated Lapping Machine

Sunnen has released the SVL-2115 automated lapping machine. Based on the same machine platform as the SV-2100 honing system, the SVL-2115 provides single setup processing of hydraulic valves, sleeves, fuel system components and other parts that are prone to distortion when honed.

The walkaway system uses an index table to automatically lap and air gage bores throughout the cycle. Gage readings are fed back to the control and the cycle is repeated until the parts are within spec.

The Sunnen lapping system handles workpiece diameters from 6.5 to 20 mm (0.26” to 0.70”) and lengths up to 12 times the bore diameter, not to exceed 200 mm (7.87”). Spindle speed range is 100-2000 rpm during lapping, but is capable of slow speeds for non-powered steps, such as lapping paste application or slow-rotation bore entry. Stroker speed is 0-350 SPM, with stroke length optimized to achieve a high degree of cylindricity.

Sunnen has developed laps and gage probes to accompany this new system along with tooling and probe changeovers to accommodate frequent changes during the course of a shift. A stack light allows operators to monitor cycle completions or faults from a distance, while a light curtain is standard. The lapping system is available with Sunnen’s SVF filtration system.
