Despite the bustling level of activity at Front Range Stone’s fabrication plant in Englewood, CO, there is clearly an order to the stoneworking process. Workers, machinery and material seem to move in perfect unison, allowing the company to work at a high level of efficiency.
The production processDuring the fabrication process, some of the most complicated work is completed on one of two Intermac CNC stoneworking centers, which were purchased from AGM. Included is the Intermac Master 1500, and its latest addition, the Intermac Master Stone 33. The new CNC router offers many new features, such as PC-based controls. The machine is fully networkable, comes with remote diagnostics and runs under a Windows XP environment. It has a 20-horsepower electrospindle and a rotary tool changer that allows operators to load tools from outside of the machine, which intends to save time and improve operator safety. It also features misalignment-free safety doors that were designed for OSHA compliance.
According to Espino, all ogee, waterfall and bullnose edges are processed on the CNC machines. Additionally, the CNC units are used for radius workpieces and odd shapes. Tooling for the CNC units is supplied by Hard Rock Tool.
To program the machines, Front Range Stone is currently scanning cardboard templates using a digitizing board, but it is considering a move to electronic/digital templating technology in the future.
Front Range Stone has a water treatment system it designed in house, also using a dehydrator from Hard Rock Tool. Espino explained that the CNC units and the Synthesis use new water, but all of the other water used in the shop is recycled.
Production and marketsThe facility operates two shifts, with 25 people working per shift. It also has 10 installation crews and four templating crews. On average, Front Range Stone completes an average of 14 kitchens per day, but that total varies depending on the size and shape of the kitchens being produced at a given point.
