The Koepfer model 150 gear hobbing machine is a machine tool used for hobbing gears using the hobbing milling technique. This machine is appreciated for its precision and reliability, especially in the precision engineering sector.
Technical Data Sheet
- Brand: Koepfer
- Model: 150
- Maximum workable diameter: 150 mm
- Maximum modulus: 4
- Maximum working range: 200 mm
- Approximate weight: 3500 kg
- Type of toothing: Horizontal hob
- Power: 400V, three phase (typical for these machines, but may vary based on specific configuration)
Main Components
- Workpiece table: Where the workpiece is fixed.
- Hobbing cutter: Performs the toothing. The module of the cutter determines the size of the gear teeth.
- Tailstock: Used to keep the piece in position during machining.
- Lubrication system: Essential to avoid overheating and excessive wear.
Mechanical Characteristics
The Koepfer 150 gear hobbing machine is designed to machine small and medium diameter gears, typically up to 150 mm. The module capacity of up to 4 allows you to produce teeth strong enough for various industrial applications.
Optimal Use Formula
The correct use of the gear hobbing machine depends on various factors:
- Cutting speed (Vc): Vc = (π * D * n) / 1000, where D is the diameter of the cutter in mm and n is the rotation speed in revolutions per minute.
- Feed per tooth (fz): fz = f / (z * n), where f is the total feed, z is the number of cutter teeth, and n is the rotation speed.
Workable Materials
The machine is capable of processing a wide range of materials, including:
- Carbon and alloy steel
- Cast iron
- Aluminum and light alloys
- Bronze and brass
Maintenance
- Lubrication: Check and replace lubricants regularly to ensure the correct functioning of the mechanical parts.
- Checking the clearances: Periodically, it is essential to check and adjust the clearances between the mechanical components to maintain the precision of the workmanship.
- Cleaning: After each use, the machine must be cleaned to avoid accumulations of chips and other residues that could compromise functionality.
Evaluation of used cars
To evaluate the purchase of a used hobbing machine, consider:
- State of wear of the cutter and mechanical components: An excessively worn cutter may indicate intensive use and the need for expensive replacements.
- Accuracy: Check the accuracy of the teeth on a test piece.
- Previous documentation and maintenance: Check whether the machine has been regularly maintained and whether the original manuals are available.
Sectors of Use
The Koepfer 150 is ideal for:
- Automotive industry
- Machine building
- Tool production
- Aerospace sector
Why is it better to buy it used?
Buying a used Koepfer 150 gear hobbing machine can represent an excellent investment thanks to the robustness and longevity of these machines, which often offer excellent performance even after many years of use. However, it is important to ensure that the machine is in good condition and that the necessary spare parts are available.
