Edming Machines for Breakthrough Use

One of Leer Technologies' business goals is to re-educate EDM machining customers and design engineers about the expanding capabilities of newer, more sophisticated equipment. Leer employs the Swiss-made SARIX SX- 100 and SX-200 Micro EDM machines for their versatility and high-performance results.

"This equipment is revolutionizing the industry," says Mary Anne Lee, president, Leer Technologies. "Versatility is our strategic catchword at Leer because we are fortunate to be in a position to pass along to our customers the value of the finest equipment available in the world. The SARIX SX-100 and SX-200 machines have enabled our engineering team to broaden our product solutions and be far more innovative and agile than anyone could have predicted ten years ago," she continues.

"We're doing precision work that no one would have guessed would be achievable while still being cost efficient. It's a very exciting time for our applications and production expansion," says Leer's Sales & Application Manager, Graham Ruck.

The company's EDM equipment produces burr-free results with no material alteration, high-quality surface finishes, superior geometry accuracy, and excellent repeatability.

In recent years SARIX has developed new features that provide great versatility in cost-effective hole-drilling capabilities, sinking and micro-milling processes. SARIX machines are configured to ensure maximum cost efficiency.

For research and high-volume production applications, in addition to more standard applications, the SARIX machines offer the following optional features: high pulse generator for larger holes, W-axis for guide position, A/B indexing axis, automatic electrode feeding spindle, automatic electrode changer, breakthrough detection capability, highcapacity filtering tank, EDM milling software for micro mold making.

The Leer team offers engineering consultation and design assistance in the development and manufacture of prototypes and partial run test runs and is also involved in multi-axis CNC EDM sinker and wire production and EDM drilling services.

Titanium, hardened steel, tungsten carbide and some ceramics are among materials normally considered difficult to machine. The SARIX machines at Leer Technologies are especially effective in producing precision results with these demanding materials, which are required in complex parts applications. Configurable for applications requiring up to eight axes of movement and a multitude of 2D milling and 3D contour milling (through specialized software), the SARIX machines offer a position accuracy of ±2µm and resolution of 0.1µm.

The SX-100 HPM worktable measures 530mm x 270mm, and the SX-200 HPM table measures 750mm x 300mm. Travels in the X, Y, Z and W (Z2) axes are 250mm, 150mm, 150mm and 150mm for the smaller machine, and 350mm, 200mm, 200mm and 150mm for the larger model. The maximum feedrate for both machines is 650mm/min for the Z axis, and 800mm/min for the X and Y axes. leertech.com
