The Spider machine is specifically designed for flange facing and grooving applications. The on-board software is engineered to calcite the initial setting position and carries out completed work cycles. This machine boasts an internally mounted flange facing and seal groove machining unit alongside a multi positional motor. Spotting will always allow a minimum distance between the cutting point and the power transmission point, with vital benefits such as little or non-chattering and higher cutting speed. Also featured in the Spider flange facer machine is a two piece mounting system that is designed for the layout to allow fast and exact ID mandrel centring for site operations, particularly for one-person jobs and applications in tight spots. A selection of gear rings completes the unit to deliver the best results for any kind of flange size.
