The equipment, CNC software and cutting tools used in one of Cyclone Manufacturing’s Mississauga, ON, facility.

Read the full story about Cyclone and its productivity achievements.

Machine Tool: The DMU 80 eVo linear from DMG MORI is a five sided, five axis simultaneous machining centre equipped with linear drives in X and Y axes for higher accuracy and faster machining speeds. The machine is equipped with an Erowa robot loader. It features an NC swivel rotary table with a 600 kg load capacity, -5/+110° B axis swivel range, and 360° C axis rotation range. Rapid traverse speeds are up to 80 m/min. It runs at 18,000 rpms and features an HSK-A63 AC motor spindle. The main spindle features a high pressure (580 psi) through-spindle coolant. The compact machine has a 2,370 x 3,250 mm footprint and has a large working area measuring 800, 650 and 550 mm in the X, Y and Z axes respectively.

CAM Software: PowerMILL NC CAM software from Delcam is designed for complex, high speed machining in a single set-up and for automated programming of complex milling operations. The software offers users a range of high speed machining and multi-axis toolpath strategies. For example, Vortex is a patent pending roughing technology for high speed machining with solid carbide tooling that helps reduce machining times by up to 60 per cent, according to Delcam. The software’s simultaneous five axis machining strategies give manufacturers control of the tool orientation around the workpiece, allowing for machining of complex parts in a single setup. An important consideration in CAM software is collision avoidance tools. The automatic collision avoidance function tilts the cutter away from obstacles by a specified clearance. When clear of the obstacle, the tool returns to the original cutting angle. Tool axis editing gives manufacturers the ability to adjust tool axis settings for individual areas of the toolpath and allows the machine to run more smoothly.

Workholding: Lang workholding products include Makro Grip five axis vises, Quick-Point zero-point clamping system and Tower products. The Makro-Grip five axis centering vises clamps at 3 mm heights. It clamps workpieces in the holding teeth contour of the jaw, requiring no endstop. The Quick-Point zero-point clamping system has a repeat accuracy of less than 0.005 mm. Simple to use, it requires manual clamping with one tightening screw.

Tooling: Seco’s EPB toolholders are balanced to 1.5G at 20,000 rpm. They have less than three microns of run out to minimize static and dynamic run out. The Jabro end mills include the JH490, a coolant-through roughing with a feed rate of 1000 ipm, the JH421 Tornado Aluminum a coolant-through end mill for finishing with a feed rate of 600 ipm, the JH410 Tornado single flute end mill for circular interpolation and true positioning on all holes, and the Aeromaster indexable aluminum roughing tools.
