Detailed Technical Data Sheet - DANOBAT Rectifier Model 1200 RP (1989)

General Overview: The DANOBAT 1200 RP surface grinder is a precision machine tool specifically designed for the cylindrical machining of workpieces with high standards of surface finish and dimensional accuracy. Manufactured in 1989 and completely overhauled in 2006, this machine is an excellent choice for those seeking a reliable, high-performance used machine. DANOBAT is an internationally recognized brand for the quality of its grinding machines, particularly appreciated in the mechanical engineering industry.

Main Components:

• Machine bed: Constructed of cast iron to ensure stability and reduce vibration during machining.
• Spindle: High precision, mounted on bearings that ensure smooth, backlash-free movement.
• Grinding wheel: 500 mm diameter, 80 mm width and 100 mm bore, allows for a large material removal capacity.
• Control system: Usually equipped with electronic and hydraulic controls for precise management of the axes.

Technical Specifications:

• Axis travel (X, Y, Z): 1200 mm, suitable for processing large workpieces.
• Grinding wheel dimensions: 500x80x100 mm.
• Total weight of the machine: 4300 kg.
• Bench Size: Generous workspace for medium to large workpieces.
• Installed power: Varies depending on the workload and type of processing.

Mechanical Features: The DANOBAT 1200 RP grinder features ball-bearing linear guides, providing precise, frictionless axis movement. The grinding spindle is designed to operate at multiple speeds, making the machine versatile for a variety of materials and finishes.

Formulas for Optimal Use:

• Cutting speed (Vc): Vc=π×D×n1000Vc = \frac{\pi \times D \times n}{1000}
  $V$ $c$ $=$ 1000 π × D × n ​Where DD $D$ is the diameter of the grinding wheel and nn $n$ is the rotation speed in RPM.
• Feed rate per revolution (fz): fz=vfnfz = \frac{vf}{n}
  $f$ $z$ $=$ n v f ​Where vfvf $v$ $f$ is the feed rate and nn $n$ is the rotational speed.

Machinable Materials: This grinder is ideal for machining a wide range of materials including hardened steels, cast irons, non-ferrous metals and hard materials such as tungsten carbide.

Maintenance: To keep the DANOBAT 1200 RP in top condition, it is essential:

• Regular lubrication: Check and replace lubricants at critical points on the machine.
• Periodic inspection of guides: Make sure the guides are clean and free from excessive wear.
• Spindle Alignment: Check spindle alignment regularly to avoid machining defects.

How to Evaluate a Good Used Car:

• Inspection documentation: Verify that the machine has undergone periodic inspections.
• Condition of guides and spindle: Check for any signs of wear.
• Machining Accuracy: Request a machining test to verify the quality of the produced part.

Areas of Use: The DANOBAT 1200 RP is widely used in the aerospace, automotive, and toolmaking industries due to its ability to machine complex parts with close tolerances and excellent surface finishes.

Advantages of Buying Used: Buying a used grinder like the DANOBAT 1200 RP allows you to get a high-quality machine at a lower cost than a new one. Thanks to the model's robustness and reliability, even a used one can provide years of efficient service, especially if well-maintained.

In summary, the DANOBAT 1200 RP grinding machine is an ideal precision machine for those looking for a high-performance and reliable used machine, capable of guaranteeing excellent results in numerous industrial sectors
