What is the reason why the lathe large pallet is very heavy?

During the turning process, the impact causes the tooth shaft in the carriage box to bend, and the rack on the guide rail is tight and loose when walking. In addition, some are careless lathes, lock the carriage screws, forget to loosen or stuck, and shake the foreign object tightly.

There are also two sides to adjust the adjustment screws of the adjustment block of the large carriage and the guide rail are too tight, and the adjustment needs to be matched left and right, but the adjustment is not tight, but it is appropriate to loosen the suitability, and the guide rail is smashed or the iron filings are stuck and the shaking is tight.

The rotary motion transmitted by the main motor passes through the transmission mechanism to make the spindle get the different speeds of the required forward and negative steering, and the spindle in the spindle box is the key part of the lathe. The smoothness of the spindle running on the bearing directly affects the machining quality of the workpiece, and once the rotation accuracy of the spindle is reduced, the use value of the machine tool.

There are several reasons why the large carriage hand crank is very heavy, the common ones are 1, the impact in the process of turning and turning makes the tooth shaft in the carriage box bend, and the rack on the guide rail is tight and loose when walking, 2, in addition, there is a careless lathe to lock the carriage screw to forget to loose or stuck foreign body to shake up tight, 3, there are both sides to adjust the adjustment screw of the adjustment block of the large carriage and the guide rail is too tight, and it is necessary to cooperate with the left and right to adjust the adjustment but not tight, but it is appropriate to loosen the suitable, 4, the guide rail is smashed or stuck iron filings cause the shaking to be tight.

If the large carriage of the lathe has greater resistance and is difficult to shake, you can try the following methods to solve the problem or reduce the resistance:1Check lubrication:

Ensure that the slide rails, transmission parts and ball screws and other components of the lathe are adequately lubricated. If lubrication is insufficient, lubrication can be performed with an appropriate lubricant. 2.

Cleaning: Check the large carriage for debris or dirt accumulation, and clean the debris on the large carriage and slide rails to ensure smooth movement. 3.

Adjust the screw nut: The adjustment device of the ball screw or guide rail in the inspection hall is only spring to ensure its normal operation. If there is a problem with the adjustment unit, it may need to be adjusted or repaired.

4.Afterburner: If the resistance is still high, you can try lifting the large carriage with more force, which may require additional effort to overcome the resistance.

If the above methods still do not solve the problem, it is recommended to contact professional maintenance or adjustment personnel, who can help you more comprehensively check and solve the problem of large drag resistance of the lathe large carriage. Remember to make sure to disconnect the power supply before making any lathe repairs or adjustments, and follow the safe operating procedures.

Summary. Hello dear, happy to answer your <>

The resistance of the lathe large carriage can be caused by a variety of reasons, and the following are some common solutions:1Check the lubrication system:

Make sure the bearings are not damaged and functioning properly, if the bearings are damaged, they need to be replaced with new ones. 3.Cleaning the workbench:

Remove debris, dust, or debris from the bench to keep the bench clean and level. 4.Adjust the height of the pallet:

According to the work requirements, adjust the height of the supporting plate to ensure that the contact area between the supporting plate and the workpiece is small. 5.Use a lathe tool with a smaller diameter:

The use of lathe tools with smaller diameters can reduce the resistance during cutting and improve work efficiency. 6.Check the workpiece material:

If the hardness of the workpiece material is high, the resistance may increase. When choosing a workpiece material, try to choose a material that is easier to process. <>

The resistance of the lathe large carriage may also involve factors such as machine tool design, materials used, etc. In addition, with the development of technology, there are some solutions to resistance, such as electric beds, etc., which can reduce resistance and improve operational efficiency through electric drive slow collapse. In addition, there are also some solutions in the field of automation, such as automatic loading and unloading systems, automatic adjustment screws, etc., which can further improve the work efficiency of the lathe and reduce the difficulty of operation.

There are several reasons for this:

1. The bolts of each pressing plate of the large supporting plate are adjusted unevenly or too tightly.

Solution: Adjust the bolts on the outer bottom surface of the large supporting plate, loosen all the bolts to check whether the adjustment bolts are adjusted freely, and then tighten them upward by hand with a wrench.

Tightened, the bolt must not be rotated again.

2. There is a lack of oil on the large pallet, and there is black oil and rust spots after the large pallet is shaken.

Solution: Use sandpaper to remove rust spots, wipe off the oil sludge with a towel, and then shake the large pallet to the other side, do it again in the same way, and then shake the large pallet back, and wipe it dry and add oil several times in a row until the oil sludge is less.

Solution: This is never to be used again, find maintenance personnel, turn over the large pallet to clean and polish.

4. The internal transmission system of the large supporting plate fails.

Solution: Find a maintenance person to check and repair.

Hehe, the main reason is that the bed is often not wiped, so that the slip box is domineering. It is necessary to reduce the utilization rate of cutting fluid as much as possible to avoid corrosion and rust on the bed guide rail! It is necessary to frequently fill the slide box and the guide rail of the machine tool, which can reduce a great burden on the operator! Thank you.

1. It is likely that the plug is loose. The plug bar is used to adjust the gap of the guide rail, there are adjusting screws (one before and after), first relax and then adjust the screw, shake the middle carriage handle back and forth, let the middle carriage move back and forth, and at the same time use a screwdriver to turn the front adjusting screw to appropriate tightness (at this time, the hand that shakes the handle will feel it), and finally tighten the rear adjusting screw, OK;

2. If the above method does not work, try to adjust the lead screw gap. As shown in the figure, the screw nut adjusting screw is used to adjust the screw clearance, and if it is adjusted too tightly, it will also make the middle carriage "stuck". When adjusting, you also need to shake the handle of the middle carriage back and forth to adjust, and at the same time observe the dial, and feel that the "neutral" is about 3 4 small grids in your hand.

Summary. The connection between the light rod and the feed box is dropped, the jointing tooth axle and the rack bite are not good, and the lever is adjusted to the gear stroke.

The gap between the lead screw and the wire nut is large, the fixing bolts of the bearing seat and the wire nut are loose, the positioning pin falls off, the clamp bar clearance is large, and the positioning of the scale disc wheel is loose. The screw and handwheel alignment pins are loose. The above situations will cause the scale of the large carriage to be inaccurate.

Shenyang 6150 ordinary lathe, the big pallet hand can't shake what's going on.

The connection between the light rod and the feed box has fallen, the jointing tooth axle is buried in the ante and the rack bite is not good, and the lever is adjusted to the gear stroke. The gap between the lead screw and the wire nut is large, the fixing bolts of the bearing seat and the wire nut are loose, the positioning pin falls off, the clamp bar clearance is large, and the positioning of the scale disc wheel is loose. The screw and handwheel alignment pins are loose.

The above situation will cause the scale of the big finger rock drag plate to be inaccurate.
