Improvements in VERICUT Version 9.3 have been made in collision checking and increasing the limit on axes per subsystem. There are improvements to core features and functionality as deflection calculations have changed to account for the entire rotating tool assembly, where previous versions only accounted for solid round tools with holders. This change in deflection along with cutting tool data and information about stock material improves part surface finish, ensures the part meets the appropriate dimensions, and extends cutter life.

Ceramic-bridge CMM

The ALTERA C ceramic-bridge CMMs use the latest metrology software, multi-sensor technology, and design to offer high accuracy measurement and efficient throughput for measurement tasks in quality laboratories and shop floor environments. The CMMs are available in with measuring volumes of 700mm x 650mm x 500mm, 1,000mm x 650mm x 500mm, and 1,000mm x 650mm x 650mm.

All machines accelerate at 1,900mm/sec2, representing an increase of 15% for the two smaller models and 20% for the largest model. Velocity is up by 38% across the product range to 720mm/s.

Maximum permissible measuring error on all machines is 1.7+L/333µm when measurements are taken of a feature L millimeter in length, irrespective of if a TP200, SP25, TP20, or PH20 probe is used.

The wrap-around air bearing configuration offers 3.5x higher stiffness than standard air bearings. They run with a reduced air film thickness for low energy consumption and give repeatable measurement results even at fast axis speeds.

Renishaw encoders with 0.05µm-resolution optical scales offer high volumetric accuracy and immunity to the ingress of contaminants. LK’s CAMIO DMIS-based, multi-sensor software enables programming and measurement based on 3D CAD data, as well as comprehensive reporting.

Turn mill center

The G220 turn mill center incorporates and refines the design principles introduced via the larger G320, G420, and G520 machines. With twin spindles, dual tool turrets, a 5-axis milling spindle and high-capacity tool magazine, the machine easily produces a variety of parts in a single setup.

Design of the G Series machines begins with a rigid, vibration damping machine bed in a mineral cast block. Each machine combines optimal stability and damping properties with high dynamics and generously dimensioned linear guides in the X- and Z-axes.

The G220’s milling spindle offers a hydrodynamically mounted Y/B axis arranged above the axis of rotation. Each turret provides movement along the X-, Y-, & Z-axis and each of the turrets’ stations can be equipped with live tooling. Additionally, the G220’s large workspace and internal layout enables simultaneous machining with the milling spindle and both turrets.
