Grinder manufactures and reconditions cutting tools.

Press Release Summary:

Engineered for structural and thermal stability, Model CTG-3 features 3-station HSK grinding wheel pack and part programming through NUMROTOplus software. Headstock is direct drive and all linear axes have glass scales. For dynamic stability, dedicated closed loop chiller controls heat build-up within grinding spindle and headstock. Standard 2D simulation allows cross-sectional visualization, while optional 3D virtual grinding simulation with machine collision detection eliminates setup time.

Original Press Release:

Grind a Broader Range of Complex Tools in Less Time

Hoffman Estates, IL - The CTG-3 tool and cutter grinder, the newest innovation from Star Machine Tools, features a small foot print for manufacturing or reconditioning cutting tools, part programming through NUMROTOplus Software, flexibility via a three-station HSK grinding wheel pack and coolant manifold change system. An auto loading system is also available for unattended operation.

Accuracy - The accuracy of the CTG-3 is highly predictable due to the integration of world-class machine components. A powerful, precision grinding spindle with HSK grinding wheel mounting locates the grinding wheel on the center of the B-axis pivot. The headstock is direct drive for ultimate positioning capability, variable RPM and low maintenance. All linear axes have glass scales.

Flexibility - NUMROTOplus® is a user-friendly, high-end application software package for producing a wide range of complex tools. The standard 2D simulation allows cross sectional visualization, while the optional 3D virtual grinding simulation with machine collision detection eliminates costly setup time. Innovative work holding and tool support options, programmable steady rests and tailstocks plus a variety of custom designed tooling enables the production of the highest quality precision cutting tools.

Reliability / Maintainability - The CTG-3 is reliable. Air purge of scales, headstock, and grinding spindle eliminates any contaminants. Full disclosure of machine drawings, documentation, and a complete parts list is available on the machine's computer. Proven diagnostic systems for troubleshooting error messages and unlimited direct access / phone support are available for the operator.

Stability - The CTG-3 is engineered for both structural and thermal stability using 3D Solid Modeling and Finite Element Analysis (FEA). For dynamic stability, a dedicated closed loop chiller controls heat build-up within the grinding spindle and headstock. The CTG-3 is designed, built, serviced and supported to maximize uptime, throughput, and profits.
