Gleason Pfauter P 1600 G CNC Gear Wheel Grinding Machine – Technical Evaluation (Year 2009)
1. Technical Evaluation Overview
The Gleason Pfauter P 1600 G is a CNC gear wheel grinding machine intended for large-diameter gear finishing. Based strictly on the provided information, the machine supports a maximum machining diameter of 1,600 mm and a maximum grinding depth of 80 mm. The axis travels are stated as X: 1,000 mm, Y: 300 mm, and Z: 1,300 mm, indicating a configuration suitable for large gears with substantial axial requirements.
The grinding system is specified with a grinding wheel size of 400 × 80 mm and a grinding spindle diameter of 80 mm. The worktable diameter of 1,200 mm with a 300 mm table bore defines the clamping envelope for large gear blanks and fixtures. The CNC system type is not specified and must be verified, as control configuration is critical for gear grinding functionality and accuracy.
Several key parameters are not provided, including gear module range, spindle power and speed, dressing system type, achievable accuracy class, coolant system details, and machine footprint/weight. These omissions limit the completeness of the technical assessment and require confirmation.
2. What to Check Before Buying
Given the stated capacities and missing details, inspection should focus on the following:
Mechanical and grinding system:
Condition of the grinding spindle (80 mm diameter), including bearing noise, vibration, and thermal behavior under load.
Integrity of the grinding wheel mounting and verification that the 400 × 80 mm wheel format is supported by the installed spindle and guards.
Wear and smoothness of the X, Y, and Z axes over their full travels, especially the 1,300 mm Z-axis used for axial gear grinding.
Accuracy and runout of the 1,200 mm worktable, including concentricity relative to the grinding spindle and condition of the 300 mm bore.
CNC and electrical system:
Identification and operational status of the CNC control, including availability of gear grinding cycles and machine-specific options.
Verification of servo drives, feedback systems, and axis synchronization essential for profile grinding.
Condition of electrical cabinets, cooling, and safety interlocks appropriate for a 2009-built machine.
Process-related equipment:
Presence and condition of any dressing unit, probing system, or in-process measurement devices, if installed.
Coolant delivery and filtration capability suitable for deep grinding (80 mm maximum grinding depth).
3. Typical Industrial Applications
Based on the provided specifications, the P 1600 G is technically suitable for:
Finish grinding of large spur or helical gears up to 1,600 mm diameter, subject to confirmation of module and tooth geometry limits.
Gear manufacturing or refurbishment applications requiring long axial travel and stable worktable support.
Heavy-industry gear finishing where controlled grinding depth and large clamping capacity are required.
Specific gear types, accuracy grades, and production suitability cannot be confirmed without additional technical data.
4. Common Risks in Used Machines
For used CNC gear grinding machines of this size and generation, typical risks include:
Grinding spindle wear, directly affecting profile accuracy and surface finish.
Axis and worktable wear, particularly in machines that have processed heavy or oversized gears.
Control system limitations or obsolescence, depending on the unidentified CNC platform and software options.
Documentation gaps, such as missing grinding data, CNC backups, or electrical diagrams, which may hinder setup and servicing.
5. Maintenance and Service Considerations
With no service history provided, maintenance considerations are limited to general technical points:
Ongoing monitoring of spindle condition, axis accuracy, and lubrication systems is essential for large gear grinding machines.
Grinding wheel handling, dressing components, and coolant systems require regular inspection due to their direct impact on grinding quality.
CNC parameters and machine-specific data should be backed up and verified before operation.
Any maintenance or overhaul planning should be based on an on-site inspection and functional testing rather than assumptions about service intervals or spare part availability.
