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?

Is the Gleason-Pfauter P 1600/2000 S Gear grinding machine Ready to Inspect?Yes. This used Gleason-Pfauter P 1600/2000 S gear grinding machine is already identifiable in stock, so a buyer can move directly to inspection planning. The listing also provides the key technical facts needed to judge fit before a visit: Siemens Sinumerik 840D control, 2000 mm maximum gear diameter, 700 mm maximum gear width, and a 2-25 mm module range. How the specifications help decide whether to inspect now The listed capacities make this machine relevant to buyers who need one machine for many applications rather than a narrowly specialized unit. With a maximum gear diameter of 2000 mm, maximum gear width of 700 mm, and a module range of 2-25 mm, the P 1600/2000 S sits in a size class that can support a wide span of production and regrinding work. That matters in real buying decisions. Automotive suppliers may evaluate it for larger drivetrain gear work. Aerospace manufacturers may look at it for demanding gear geometries and controlled finishing processes. Mold making operations can consider it when internal capability expansion includes precision gear components. Medical device and electronics manufacturers may not need the full size envelope every day, but they often value flexible CNC equipment that can support varied precision programs across product lines and subcontract work. In that sense, this is a classic versatile all-rounder: one machine, many applications. Because the technical envelope is already stated, a buyer does not need to start with broad discovery. The immediate question becomes narrower and more useful: does the actual machine condition match the listed platform and capacity? That is exactly the point at which an inspection becomes worthwhile. What to confirm on site before negotiation or delivery planning A serious inspection should focus on facts that affect buying value quickly. First, confirm the Siemens Sinumerik 840D control status, including startup behavior, screen condition, and whether machine parameters and operational menus are accessible. Second, verify that the machine matches the stated capacity figures so there is no mismatch between listing and application. Third, inspect the overall machine scale against your plant constraints, because this unit has a listed weight of 35,000 kg and requires installation space of 6900 x 8400 x 3700 mm. Those last two figures are especially important if your purchase decision depends on transport or relocation cost. A machine of this size may be technically suitable but operationally inefficient if your facility cannot receive it easily. By contrast, if your site and lifting plan already support this footprint and mass, the listing gives enough information to move from interest to inspection without delay. In practical terms, this machine is ready to inspect when your team needs a large-format CNC gear grinding platform with broad application potential and you want to validate condition before discussing final deal terms. Related Questions Is the Gleason-Pfauter P 1600/2000 S ready to inspect? Yes. It is identified by stock number 812569, and accompanied by the core specifications a buyer needs for inspection planning. Is this Gleason-Pfauter P 1600/2000 S currently identifiable in stock? Yes. The listing provides stock number 812569 and confirms the machine location in the Czech Republic. What can a buyer verify during inspection of this machine? The buyer can verify the Siemens Sinumerik 840D control, the 2000 mm maximum gear diameter, the 700 mm maximum gear width, and the machine's overall installation requirements. Is the P 1600/2000 S a fit for mixed-industry production? Yes. Its module range of 2-25 mm and large work capacity make it relevant for automotive, aerospace, mold making, medical device, and electronics-related applications.
