A vertical milling machine is a fundamental tool in the manufacturing and machining industries. Ensuring that the table of your vertical milling machine is level is crucial for achieving accurate and high - quality machining results. As a professional vertical milling machine supplier, I'm going to share with you some effective methods to level the table of a vertical milling machine.
Understanding the Importance of a Level Table
Before diving into the leveling process, it's essential to understand why a level table matters. A non - level table can lead to a variety of issues. Firstly, it affects the accuracy of the machining operations. If the table is not level, the workpiece may not be held in the correct position, resulting in uneven cuts and inaccurate dimensions of the machined parts. Secondly, it can cause excessive wear on the cutting tools. Uneven forces are applied to the tools when the table is not level, which shortens their lifespan and increases the cost of production.
Tools Required for Leveling
To level the table of a vertical milling machine, you'll need a few essential tools:
- Precision Level: A high - quality precision level is the most important tool for this task. It allows you to measure the horizontal and vertical angles of the table accurately.
- Shims: Shims are thin pieces of metal or plastic that can be used to adjust the height of the table at different points. They come in various thicknesses and are crucial for making fine adjustments.
- Wrenches: You'll need wrenches to loosen and tighten the bolts that hold the table in place. Make sure to use the appropriate size of wrenches to avoid damaging the bolts.
Step - by - Step Guide to Leveling the Table
Step 1: Preparation
First, clean the machine thoroughly, especially the table surface and the base where the machine sits. Any debris or dirt can interfere with the leveling process and lead to inaccurate results. Remove all the tools and workpieces from the table to ensure a clear and stable working area.
Step 2: Initial Inspection
Place the precision level on the table in different directions (lengthwise and crosswise). Observe the bubble in the level. If the bubble is not centered, it indicates that the table is not level. Note the direction and degree of the misalignment.
Step 3: Adjusting the Feet
Most vertical milling machines are equipped with adjustable feet. Loosen the locking nuts on the feet using a wrench. Then, turn the adjustable feet clockwise or counter - clockwise to raise or lower the corresponding corners of the machine. Make small adjustments at a time and re - check the level after each adjustment. It's important to make gradual changes to avoid over - correcting.
Step 4: Using Shims
If adjusting the feet is not enough to level the table, shims can be used. Place the shims under the base of the machine at the points where the table is low. Start with thin shims and add more as needed. Again, check the level after each addition of shims to ensure that you're moving in the right direction.
Step 5: Final Check
After making all the necessary adjustments, place the level on the table again and check it in multiple directions. Make sure that the bubble is centered in all positions. If there are still minor discrepancies, make further fine - tuning adjustments using the shims or by slightly adjusting the feet.
Advanced Tips for Leveling
- Thermal Expansion: Keep in mind that the temperature can affect the leveling of the machine. Metal expands and contracts with temperature changes. It's best to level the machine in an environment with a stable temperature or allow the machine to reach thermal equilibrium before leveling.
- Regular Maintenance: Leveling the table is not a one - time task. Regularly check and re - level the machine to ensure consistent performance. This is especially important if the machine is moved or if there are significant changes in the working environment.
