Page 44 of 50 43 Deep-Hole Drilling and Milling Machines Streamline Moldmaking Unisig features its USC and USC-M Series machines that combine deep-hole drilling and milling capabilities, which the company says enable mold shops to reduce setup time, increase accuracy and eliminate mold design restrictions. The USC Series column-type machines generate highly accurate holes rang- ing to 1.5" in diameter in large workpieces. They are available in table-weight capacities ranging to 50 tons and are suitable for mold plates and frack pumps. These machines enable the processing of large and small parts with four- sided machining capability in a single setup. The USC-M series machines use two independent spindles for gundrilling and BTA drilling and another CAT 50 machining spindle. When this additional capability is combined with a rotary workpiece table and programmable headstock inclination, accurate deep-hole drilling and all standard high-performance machining capabilities are avail- able within the working envelope. The seven axes of control on the M-Series machines use the B, A, X, Y and Z axes for five-axis machining operations, the W axis for the combined gundrilling and BTA deep-hole drilling spindle and the U axis for machining. This provides 3+2 machining to make deep-hole drilling and machining of compound angles faster and improves productivity and throughput by reducing setups and eliminating transfers to multiple machines. Unisig / 414-252-3802 / Clamp Elements Are Versatile for Small-Batch Parts Production The clamping elements of Erowa's CleverClamp system are specifically tailored to the manufacturing of one-off and small-batch parts. The company says that they are simple to handle and serve a wide variety of applications while decreas- ing set-up times, increasing machining times and improving productivity. The basic rails of the CleverClamp system are calibrated to fit the Erowa UPC and Erowa MTS production tooling systems. The wide range of clamping elements can be quickly positioned on the serrated base rails and can be used either horizontally or vertically. The base rails provide the flexibility to attach workpieces of varying shapes and sizes in a limited amount of space. An added feature of the CleverClamp system is that it can be universally automated. This increases customer's machine use by making use of marginal and night hours when the CleverClamp system is combined with an Erowa automation solution. Erowa Technology Inc. / 800-536-4894 / New Feature on CAM Software Simplifies Five-Axis Programming PowerMill 2019 from Autodesk offers three- and five-axis programming tools to help manufacture complex parts with new additive and subtractive technology. Autodesk says that introducing enhanced three-axis high- efficiency roughing and new five-axis collision avoidance tools will generate more efficient tool paths with fewer tool retractions, shorter cycle times and increased tool life. Automatic Tool Tilting is a new option to sim- plify five-axis programming regardless of the model shape or the toolpath type. The user defines the required shank and holder clearance distance and PowerMill does the rest. Collisions and near misses are identified and automatically avoided with smooth machine motion, which helps prevent dwell marks and other imperfections. PowerMill's new setup entity helps synchronize the connection between tool paths and NC programs. Autodesk says that this enables users to add tool paths to a setup and have confidence that the changes they make are automatically passed to the associated NC program. Users can use setups with fixture offsets to simplify the programming of parts using multiple operations or fixture locations. All manufacturing data can be sent to Fusion Production for cloud-based collaboration. Autodesk / 877-335-2261 /
