The used Wyssbrod Type 6 is a high-quality machine tool, known for its robustness and precision. Below is a detailed technical data sheet based on information available for similar machines:

Wyssbrod Type 6 Technical Data Sheet

1. Structure and Main Components:

• Frame: Built in sturdy cast iron to reduce vibrations during machining.
• Table: Table dimensions typically 1255 x 205 mm, with high load capacity to support large workpieces.
• Working axis: The X, Y, Z axes allow precise movements, with travels of 500 mm, 50 mm, and 80 mm respectively for the vertical axis.
• Spindle: Variable speed spindle, reaching a maximum of 2800 rpm. Spindle power around 0.4 HP.
• Accessories: Typically includes various milling accessories such as vises, dividing heads, and milling tools.

2. Mechanical Characteristics:

• Precision: High precision in movements thanks to quality guides and feed screws.
• Working speed: Adjustable spindle speed allows for working on both harder and softer materials.
• Cutting capacity: Excellent for precision work on metals, alloys and similar materials.

3. Optimal Usage Parameters:

• Formula for optimal progress: $V$, Where:
  • VfV_f $V$ f ​=
  • NN $N$ = number of spindle revolutions
  • FF $F$ = feed per tooth
  • ZZ $Z$ = number of teeth of the tool
• Machinable materials: Steel, aluminum, bronze, and other metals. For each material, it is essential to adjust the spindle speed and feed rate based on the hardness and strength of the material.

4. Maintenance:

• Lubrication: Check and replenish the lubrication system regularly to ensure smooth operation.
• Cleaning: Remove chips and debris from the machine after each use to prevent damage to the guides and gears.
• Checking the guides: Periodically check the condition of the guides and feed screws for wear or excessive play.

5. How to Evaluate a Good Used Item:

• Cosmetic Condition: Make sure there are no signs of excessive wear, cracks in the frame, or structural damage.
• Operation: Test the machine to ensure that the spindle and table move smoothly and that the speeds are adjustable.
• Documentation: Check if the machine has documented maintenance, and check for the presence of original accessories.

6. Areas of Use:

• Precision Mechanics: Ideal for the production of high-precision mechanical components.
• Tooling: Frequently used in the production of tools and equipment.
• Industrial Engineering: Suitable for the production of machinery parts and tools.

Why It's Better to Buy Used:

Buying a used milling machine like the Wyssbrod Type 6 can be advantageous for the following reasons:

• Cost savings: Used machines, if in good condition, offer high performance at a fraction of the cost of a new one.
• Proven reliability: Used branded machines such as Wyssbrod are often already tested in production environments and maintain their efficiency over time.
• Spare parts availability: Being a popular model, it is relatively easy to find spare parts and accessories.

This model is an excellent choice for those who need a robust and precise milling machine without having to face the high cost of a new machine.
