Used Gleason 300TWG Gear Grinder

This 2016 Gleason 300TWG gear grinder is available for immediate inspection and production assessment. Engineered for high-precision gear finishing, this unit features a 300mm grinding diameter and is equipped with a Siemens CNC system. Whether you are scaling automotive transmission production or manufacturing aerospace components, this machine offers the precision and control required for complex gear geometries. It is an ideal capacity solution for shops needing to integrate reliable, high-precision grinding without the lead times associated with new equipment.

Core Specifications and Production Impact

These specifications define the machine's operational envelope and part-processing capabilities. Reviewing these parameters is essential to ensure the 300TWG aligns with your specific gear manufacturing requirements.

Specification Value Production Impact
Model Gleason 300TWG Industry-proven platform for precision gear finishing.
Grinding Diameter 300 mm Maximum external diameter (OD) capacity.
X-Axis Travel +30 / -210 mm Radial positioning range for varied gear geometries.
Y-Axis Travel 85 – 240 mm Vertical positioning for face width and gear placement.
Z-Axis Travel 100 – 500 mm Maximum shaft or gear length capacity.
CNC System Siemens Industry-standard interface for programming and diagnostics.

Application Suitability

The Gleason 300TWG is engineered for versatility across several high-demand sectors. Given its 300mm grinding diameter, it is particularly well-suited for:

  • Automotive: Efficient finishing of transmission gears, differential gears, and planetary sets.
  • Aerospace: High-precision requirements for actuator gears and auxiliary power unit components where surface finish is critical.
  • Precision Tooling: Producing high-accuracy gear components for injection molding or die-casting applications.
  • General Industrial: Ideal for small-to-medium batch production of precision spur and helical gears.

When evaluating this machine, consider your current tooling inventory. The Siemens CNC platform allows for straightforward integration into existing production environments, provided your team is familiar with the Siemens programming architecture.

Evaluating the 300TWG for Your Workflow

Selecting a used gear grinder requires matching the machine’s "envelope" to your specific part family. The Gleason 300TWG’s axis travels are optimized for precision rather than heavy-duty roughing. The X-axis range (+30 / -210 mm) provides sufficient clearance for complex gear geometries, while the Z-axis (100-500 mm) supports a wide variety of shaft-type gears. If your production involves parts that consistently fall within the 300mm diameter limit, this machine provides the rigidity and control necessary to maintain tight tolerances.

Assessing the Gleason 300TWG for Your Shop

To determine if the Gleason 300TWG is the correct fit, compare the machine's specifications against your "worst-case" part scenario. Consider the following:

  • Size Compatibility: Do your highest-volume parts exceed the 300mm grinding diameter? If not, this machine is appropriately sized.
  • Process Requirements: Does your process require the precision and repeatability that the Siemens CNC/Gleason combination is known for?
  • Integration: Does your facility currently operate with Siemens-based controls, or can your programming team adapt to this interface?
  • Throughput: Are you looking to offload specific gear grinding tasks from larger, less efficient machines to a dedicated, specialized unit?

Frequently Asked Questions

What is the maximum gear diameter this machine can grind?

The Gleason 300TWG has a maximum grinding diameter of 300 mm. It is best suited for parts that fall within or below this threshold to ensure optimal grinding performance and clearance.

Is the Siemens CNC system compatible with standard gear grinding software?

Yes. The Siemens CNC system is an industry-standard controller. Most modern gear grinding software packages are compatible with this platform, though you should verify your specific post-processor requirements during the inspection phase.

What types of gears can be produced on this machine?

The 300TWG is a versatile platform capable of handling various gear types, including spur and helical gears. Its axis configuration allows for the precision finishing required in automotive and aerospace applications.

Can I inspect the machine under power?

Yes. We facilitate inspections for qualified buyers. We recommend bringing a sample part or a representative drawing to verify the machine's setup and axis travel against your specific production needs.
