I AM SELLING A USED LAPPING MACHINE. BRAND GEHRING MODEL P 300-63 YEAR OF CONSTRUCTION 1967 STROKE 5-300MM LIFTING SPEED 0-19M/MIN PRICE ON REQUEST 

Technical Data Sheet for 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 surface finishing process through fine abrasion. This process is essential for achieving 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 the lifting system that can reach speeds of up to 19 mm/min.
• Lapping Stroke: Adjustable from 5 to 300 mm, to suit different applications and materials.
• Lapping Tool: Mounted on a rotating spindle, designed to ensure a uniform and precise finish.
• Lubrication and Cooling System: Maintains optimum temperature and lubrication during the lapping process.

3. Technical Characteristics

• Lapping stroke: 5-300 mm
• Lifting Speed: 0-19 mm/min
• Workable Materials: Metals, alloys, and in some cases composite materials, depending on the tool configuration 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 workpiece size 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): This should be adjusted based on 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 process specifications.

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 the accumulation of abrasive dust and debris that can affect performance.
• Adjustments: Make periodic adjustments to the lift stroke and speed to ensure optimum operation.

7. Verification of used cars

• Wear Check: Check the wear of tools and major components such as the spindle and guides.
• Operation Tests: Perform tests to ensure the machine operates properly at all speeds and travels.
• Component Condition: Check that there are no signs of damage or malfunction in the lubrication and lifting systems.
• Documentation: Request documentation of previous maintenance and repairs.

8. Sectors of Use

• Mechanical Industry: For the finishing of precision components and for applications where close tolerances are required.
• Aerospace Industry: For the machining of engine parts and other components requiring smooth, flawless surfaces.
• Automotive Industry: For the treatment of engine parts and components that require high precision.

9. Why Buy Used

• Lower Cost: Buying a used machine like the Gehring P 300-63 is often significantly cheaper than buying 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.
