CNC Software

To support machine tools the AMC has invested in software which includes:

Solidworks: 3D design software Edgecam: CNC programming and toolpath generation software, full 5-axis capability Vericut: Tool path verification and the material removal process simulation, detecting errors in CNC programs. Sandvik InvoMilling: Process for machining gears and splines for small batch production and short lead times – benefits from 5-axis machining capability to produce different gear profiles with the same set of tools.
Full Toolroom facilities

• Manual turning, milling, surface grinding
• Programmable band saw

Other facilities

• Oven and Cryogenic assembly
• Nikon off-line tool presetter, tooling ID chip system
• Dot matrix part marking
• Ultrasonic part cleaning facility

Can we help? Castings production tradition dates back to 1951. Long term experience in castings production is currently used for production of demanding grey iron and nodular iron castings for metallurgical and engineering companies in the Czech Republic and abroad. The operation unit includes also a pattern shop and scales treatment center. The unit obtained product certificates from Bureau Veritas for the entire product range and Lloyd's Register for grey iron and nodular iron castings with a piece weight up to 15 000 kg.
