Technical Data Sheet of the Gressel JNF Keyway Milling Machine

General Description: The Gressel model JNF keyway milling machine is a versatile and robust machine tool, mainly used for precise machining of keyways and keyways in different types of metal materials. It is particularly popular in industries such as mechanical manufacturing, precision engineering and industrial maintenance.

Main Technical Features:

• Manufacturer: Gressel
• Model: JNF
• Bench dimensions: 1000 x 270 mm
• X/Y/Z Axis Movement: 750/145/280 mm
• Spindle Rotation Speed: 180-2950 g/min
• Weight: Not specified (the structure of the machine suggests a significant weight, suitable to guarantee stability during processing)
• Control System: Manual or automated depending on the configuration
• Workable Materials: Steels, light alloys, ferrous and non-ferrous materials.

Main Components:

• Spindle: Capable of operating at variable speeds between 180 and 2950 rpm, allowing both coarse and precision machining.
• Work table: Generous dimensions for large pieces, with movements on the X, Y and Z axes sufficient for most typical machining operations.
• Feed System: The axes are manually controlled with the possibility of automation, ensuring precision and optimal control during the milling operation.

Optimal Use Formulas:

• Cutting Speed ​​(V): $V$
  • D : Tool diameter (mm)
  • N : Spindle rotation speed (rpm)
• Feed per Tooth (fz): $f$
  • F : Total feed (mm/min)
  • Z : Number of tool teeth

Maintenance: The router requires regular maintenance to ensure longevity and precision over time. Some key points include:

• Lubrication: Periodic checking and replacement of the lubricating oil of the axes and spindle.
• Cleaning: Removal of chips and processing dust to avoid blockages or damage to moving components.
• Inspection: Periodically check bearings, guides and feed screws for wear and play.

Checking a Good Used Car:

• Condition of the Board and Modes: Make sure there are no signs of excessive wear or damage.
• Axis Accuracy: Check for excessive play or irregular movements in the X, Y, Z axes.
• Spindle Condition: Check that the spindle has no radial or axial play and that it operates without abnormal vibrations.

Application Sectors: This milling machine is particularly suitable for mechanical workshops, component manufacturing companies and sectors that require the creation of grooves and keys with high precision.

Advantages of Buying Used: Purchasing a used milling machine like the Gressel JNF can be convenient for companies that want access to high-quality machinery at a reduced price, especially when the machines are well maintained and still provide high performance.
