Low-Profile Rotary Table
The GD210LP low-profile rotary table from Hardinge is said to feature rigidity, speed, accuracy and repeatability. Large diameter bearings and a fail-safe clamping system provide high stiffness and high rigidity for parts weighing as much as 220 lbs. The table uses 233 foot-pounds (315 Nm) of clamping torque to handle off-center drilling, cross-axis milling and other high-force cutting applications.

SMW Autoblok says its TX Pull-Down chuck features repeatability of up to 0. 0004″ (0. 01 mm) and is capable of operating under aggressive cutting conditions.
Read MoreMagnets Lift Flat, Round Materials
Eriez’s SafeHold XPL line of magnets can use one magnet to lift either flat or round materials. The magnets are available in six models with capacities ranging from 400 to 5,000 lbs for flat materials and 300 to 4,000 lbs for round materials. The small, lightweight magnets are constructed from Erium 3000 rare-earth, magnetic material, and they feature a powerful, magnetic force.
Read MoreCompact, High Speed Rotary Tables
Tsudakoma TN-101, TN-131, TN-161 and TN-201 compact, high speed, tilting rotary tables from Koma Precision use a dual taper, double-disc braking mechanism, which generates massive clamp torque—an increase of 320 percent when compared to previous models. The one-piece monoblock frame construction permits maximum rigidity. The tables feature an indexing and tilting repeatability of ±2 arcseconds and are available with a full range of options including rotary scales and various chucks and collets.

Lathe and Feeder Talk Via Ethernet Interface
Research into the connectivity and communication between machine tools and equipment like bar feeders, part unloaders, pallet systems and even high-pressure coolant systems is yielding useful ability on the shop floor. In this case, LNS uses Internet technology in its S65 bar feeder to communicate with a PC-based Fanuc CNC running a Mori-Seiki NZ2000 lathe.

Automation Helps Move To High-Volume Production
This tool manufacturer had to automate its processes after switching from low-volume special orders to high-volume production runs. Since implementing Tsudakoma tilting rotary tables along with robotics and a pallet conveyor, the shop has increased sales by 400 percent.
Read MoreModular Fixturing System
The Demmeler modular fixturing system from Bluco features accurate five-sided welding tables made of high-tensile-strength steel. Angles, spacer blocks, clamps, positioning and clamping bolts and universal stops can be assembled into a ready-to-use welding fixture in a matter of hours, the company says. The system is said to be ideal for prototypes, spares and other short-run jobs, the company says.
Read MoreFourth Axis Reduces Part Cycle Times
The FANUC DDR/B from Methods Machine Tools is a rotary fourth axis designed specifically to complement the speed and versatility of the FANUC RoboDrill VMC. By eliminating the positioning delays of traditional rotary tables, it reduces part cycle times. The fourth axis can unclamp, rotate 180 degrees and reclamp in less than 0.
Read MoreCNC Rotary Table Features Carbide Worm System
The 5AX-200II CNC rotary table from Lyndex-Nikken is said to perform with high accuracy and fast rotating and tilting speeds. The company’s patented carbide worm system ensures wear resistance, rigidity and the rapid speeds of this rotary table. The carbide worm system uses a carbide worm screw and ion nitrided worm wheel rather than a conventional bronze or bronze-alloy actuation mechanism.

Hydraulic Workholding Doubles Output
When customer-supplied fixtures just weren’t cutting it, this automotive shop turned to Advanced Machine & Engineering for dedicated, hydraulic tombstones to use on its high-volume production runs. The new fixtures have since reduced load/unload time, cycle time and scrap rates while providing error-free loading.
