SIMPLE TO SOPHISTICATED WIRE MACHINES
Almost half of each EDM-focused job shop will perform simpler work that requires no more than 3 axes. These Wire and Die Sinker Machines from AccuteX EDM meet those needs with features that range from simple to sophisticated.
At IMTS 2012 in Chicago, AccuteX EDM (Mason, OH), a Division of Absolute Machine Tools, Inc. will exhibit several EDMs in Booth E-5225, ranging from 3- to 5-axes with a full range of features. Recent studies of EDM users have found that almost half of each EDM-focused job shop will perform simpler work, requiring no more than 3 axes. As such, AccuteX will present its new EZ-53SA 3-axis CNC wire model. Its X, Y, Z work envelope is 19.7 in x 11.8 in x 7.1 in. Featuring a reliable AWT (Automatic Wire Threader) and the advanced Windows-based CE control, it can accommodate more than the average jobs that come into a shop. The specific machine at the show will have the optional 4th axis indexing capability. All of the consumable items that fit on other AccuteX EDMs are compatible with the EZ-53SA.
On the other end of the sophistication spectrum, AccuteX will also show its recently introduced SP-300iA 5-Axis CNC Wire EDM that features the latest “Microsparking Technology”, the MST-II function that provides exceptional part finishes. Aerospace and medical industries in particular have demands for low recast and fine finishes.
Further, this machine is built for rigidity with a Meehanite cast honeycomb base, highly-ribbed column that is mounted with oversized UVZ axis and reinforced lower arm for added stiffness. All castings are stabilized and subjected to rigorous testing to insure maximum strength, high precision, and durability. The X, Y, Z working range is 13.8 in x 9.8 in x 8.7 in. U and V axes are both 3.15 in. The U-V axis mechanism is placed in a cabinet above the working area, assuring optimal rigidity and protection from humidity and physical damage.
The axes are driven by means of closed-loop AC servo motors with 0.000004 in resolution and controlled by a linear glass scale feedback system. The SP-300iA also incorporates the latest generation ball-retainer type guideways which reduce 90 percent of friction variation compared to conventional guideways. www.accutexedm.com
