High-speed milling for hard materials

Roku-Roku's HC-658 VMCs are high-precision machines for high-speed hard milling and graphite-machining tasks. And the company's new mid-sized Super Hybrid machine, the HC-548EX, has a 60 ft.² footprint, making it well-suited for hard milling and electrode-making.

Flexibility, speed, and precision with injection molding machine

The Cincinnati Milacron Magna V vertical-insert injection molding machine combines digital positioning with an open-access C-frame for flexibility, speed, and precision. The machines sport an ergonomic design and ANSI-compliant safety features. They come with clamp force of 30, 50, 80, 130, 200, or 280 ton, with stationary, shuttle, or rotary tables. Injection unit sizes range from 0.7 to 54 oz. Digital transducers, immune to EMI/RFI noise, provide positioning accuracy of ±0.001 in. for each critical axis, giving precise control of injection, sled, clamp, ejector, and table motion. Process-specific packages are available for products including needles and tube and hose connections.

Whirling attachment improves bone-screw threads

Tornos' thread whirling attachment is said to improve the whirling of the large thread sizes typically found on hip or “lag” orthopedic bone screws. The devices operate on the counter or “sub” spindle of the company's Deco Swiss-type turning centers. They also adapt to existing Tornos whirling units. The attachment uses replaceable carbide tooling inserts that change quickly and give fine finishes on titanium and stainless steel. For external threading, the device uses six inserts, which the company says increases tool life and cutting speed as compared to other devices.

Robots for heavy loads

TH1050 Scara robots are for high-speed operations such as packaging and assembly of medical applications. The robots' low-profile, duct-less design and heavy-duty housings give them the stability required for such applications. They reach composite speeds of 8.73 m/sec and three-axis speeds of 2,000 mm/s. Standard cycle times are 0.48 sec with a 2 kg payload. Maximum payload is 20 kg. The robot's rigid arm handles continuous hours of heavy loads. Arm can extend to 1,050 mm. Positioning repeatability is ±0.03 mm for the X-Y plane, ±0.02 mm for the Z-axis, and ±0.03° for axis 4 (Z-axis rotation).

High-volume Part at high speed

The ANW-4100 produces high-volume precision parts at high speeds. The twin-spindle machine features built-in automation with the company's four-axis rack-and-pinion swing-arm robot, which provides fast and smooth simultaneous multi-axis movement to access all sides of the traverse axis for minimum cycle times. The lathe runs at 3,000 rpm with 30 hp and sports a 12-position turret. Units also include in-process auto-gaging.

Nano boring tools provide low runout

Graflex NanoBore boring tools provide high part-finish with low runout. Six solid carbide as well as indexable-insert tools with steel or carbide holders come in 0.012 to 0.315-in. diameters. Indexable tools feature through-coolant capability for good chip evacuation and predictable tool life. A special axial, fine boring head features micrometer adjustments in increments of 0.0004 in. and vernier adjustments of 0.0001 in. on bore diameter. Additionally, two different kits are available that include the precision head, a reduction bushing, setting keys, magnifying glass, instructions, and a choice of tooling.

Vertical machining center contours at high acceleration

The NV4000 DCG (Driven at the Center of Gravity) features several special technologies for accurate contouring at high acceleration. DCG ensures that the net driving force acts through the center of the axis. Force Loop Advanced Shape, another of the technologies, provides a rigid platform because machining forces traverse across the arch-shaped column and through the bed, forming a closed loop. And Minimum Moving Mass was used to develop an ideal machine mass. Machines have 23.6×15.7×15.7 in. work envelopes and feature 12,000 rpm (20,000 rpm optional), 40-taper spindles.
