The CTG-3 tool and cutter grinder features a small footprint for manufacturing or reconditioning cutting tools; part programming through NumrotoPlus Software; flexibility through a three-station HSK grinding wheel pack; a coolant manifold change system; and an automatic loading system for unattended operation. The accuracy of the tool and cutter grinder is predictable due to the integration of machine components, the company says. A precision grinding spindle with HSK grinding wheel mounting locates the grinding wheel on the center of the B-axis pivot. According to the company, the headstock is direct-drive for ultimate positioning capability, variable rpm and low maintenance. All linear axes have glass scales. The software package is designed to produce a range of complex tools. The standard 2D simulation allows cross-sectional visualization, while the optional 3D virtual grinding simulation with machine collision detection is said to eliminate costly setup time. According to the company, workholding and tool support options, programmable steady rests and tailstocks and a variety of custom-designed tooling enables the production of quality precision cutting tools. The grinder is engineered to be reliable because the air purge of scales, headstock and grinding spindle eliminate contaminants. Full disclosure of machine drawings, documentation and a complete parts list are available on the machine's computer; and diagnostic systems for troubleshooting error messages and unlimited direct access/phone support are available for the operator. The grinder is also engineered for both structural and thermal stability using 3D solid modeling and Finite Element Analysis (FEA). For stability, a dedicated closed-loop chiller controls heat buildup within the grinding spindle and headstock. According to the company, the grinder is built to maximize uptime, throughput and profits.
Editor PickWhen Grinding Is Like Turning
This shop leverages a high-speed peel-grinding process that resembles turning to effectively grind challenging materials such as carbide. Inherently low grinding forces mean high material-removal rates are possible.
