Technical Data Sheet of the Used Equipment: Gehring P 300-63 lapping machine

Brand: Gehring
Model: P 300-63
Year of construction: 1967
Type: Lapping machine

1. General Description

The Gehring P 300-63 lapping machine is a used precision machine, designed for the lapping process, i.e. the processing of surfaces by fine abrasion. This process is essential to achieve high quality finishes and very tight dimensional tolerances.

2. Main Components

• Structure: Made of high strength steel to ensure stability and rigidity during the lapping process.
• Movement System: Includes lifting system that can reach speeds up to 19 mm/min.
• Lapping machine stroke: Adjustable from 5 to 300 mm, to adapt to different applications and materials.
• Lapping Tool: Mounted on a rotating chuck, designed to ensure a uniform and precise finish.
• Lubrication and Cooling System: Maintains optimal temperature and lubrication during the lapping process.

3. Technical Characteristics

• Lapping machine stroke: 5-300 mm
• Lifting Speed: 0-19 mm/min
• Workable Materials: Metals, alloys, and in some cases composite materials, depending on the configuration of the tools and the type of abrasive used.

4. Formulas and Parameters of Optimal Use

• Lapping Speed ​​(V): The optimal lapping speed can be calculated based on the size of the workpiece and the type of abrasive. The general formula is:
  V=D×π×N1000V = \frac{D \times \pi \times N}{1000}
  $V$ $=$ 1000 D × π × N ​Where

  • DD $D$ = Tool diameter in mm
  • NN $N$ = Tool speed in rpm

• Depth of Cut (d): Must be adjusted according to the required tolerance and the hardness of the material. A typical formula is:
  d=FAd = \frac{F}{A}
  $d$ $=$ A F ​Where

  • FF $F$ = Cutting force in N
  • AA $A$ = Contact area in mm²

5. Workable Materials

The Gehring P 300-63 lapping machine can process various types of metals and alloys. Common applications include:

• High strength steels
• Aluminum alloys
• Brass
• Hard metals such as tungsten

The choice of material depends on the lapping tool used and the specifications of the process.

6. Maintenance

• Lubrication: Check and maintain the oil level in the lubrication system. Use oils recommended by the manufacturer.
• Component Inspection: Regularly inspect the lift system, spindle and guides for wear and damage.
• Cleaning: Keep the machine clean to avoid buildup of abrasive dust and debris that can affect performance.
• Adjustments: Make periodic adjustments to the stroke and lift speed to ensure optimal operation.

7. Verification of used cars

• Wear Check: Check the wear of the tools and main components such as the chuck and guides.
• Operation Tests: Perform tests to ensure that the machine operates correctly at all speeds and strokes.
• Condition of Components: Check that there are no signs of damage or malfunctions in the lubrication and lifting systems.
• Documentation: Request maintenance documentation and previous repairs.

8. Sectors of Use

• Mechanical Industry: For finishing precision components and for applications where tight tolerances are required.
• Aerospace Industry: For the processing of engine parts and other components that require smooth and imperfection-free surfaces.
• Automotive Industry: For the treatment of engine parts and components that require high precision.

9. Why Buy Used

• Lower Cost: Purchasing a used machine like the Gehring P 300-63 is often significantly cheaper than purchasing a new one.
• Historical Value: Quality machines like this, if well maintained, can offer excellent performance even after many years of use.
• Reliability: Well-maintained machines have proven their reliability over time.
