Usage Procedure

1. Preparation : Check that the machine is in good condition and that all systems are functional. Make sure the table and spindle are clean and free of debris.
2. Loading the Workpiece : Place the workpiece on the work table, using the appropriate fasteners.
3. Parameter Setting : Configure the machine for the specific processing, setting the spindle speed, feed and cutting depth parameters.
4. Starting the Machine : Start the machining cycle and monitor the process to ensure that the part is machined correctly and without problems.
5. Inspection and Maintenance : After each processing cycle, inspect the machine for signs of wear and make sure that all components are in good condition.

Matching accessories

• Fixing Devices : Clamps, mandrels and brackets for correct immobilization of the pieces.
• Measuring Instruments : Calipers and micrometers for precise control of the dimensions of the machined piece.
• Automatic Lubrication System : To keep the machine well lubricated and functioning optimally.

Mathematical Formulas for Optimal Use

• Cutting Speed : The cutting speed (V) is calculated using the formula V=π×D×N1000V = \frac{π \times D \times N}{1000} $V$ $=$ 1000 π × D × N ​, DD $D$ is the spindle diameter in mm and NN $N$ is the spindle speed in RPM.
• Feed : The feed (f) is calculated with the formula f=VNf = \frac{V}{N} $f$ $=$ N V ​, VV $V$ is the cutting speed and NN $N$ is the spindle speed.

Workable Materials

The Leadwell MCH 400 is particularly suitable for:

• Aluminium : Thanks to its robust structure and the precision of the spindle.
• Steel : With appropriate tools and processing parameters.
• Other Light Metals : Also suitable for other light metals and alloys.

Maintenance

• Regular Cleaning : Remove chips and processing residues from the machine after each use.
• Oil Check : Check and replace lubricants and cooling fluids regularly.
• Component Inspection : Periodically check guides and bearings for wear or damage.

Evaluation of used cars

To ensure a Leadwell MCH 400 is in good condition, consider:

• Paint Condition : The original paint and the absence of obvious signs of wear indicate limited use and good maintenance.
• State of the Components : Check that the spindle and the axis movements are free and free of play.
