It is well known that the RE of pores is the last process of the hole system. And if we encounter a problem, what should we do? Some of the problems, measurements and measurements in the actual application of the reference are compiled by Xiaobian.
1
The roughness of the inner hole is not good
reason
Cutting speed is too high.
The selection of cutting fluid is not appropriate.
The main corner of the hinge tool is too large and the hinge blade mouth is not on the same circle.
The balance of Re-REP holes is too large, the amount of reef is uneven or too small, and the local surface area is not articulated.
The reef cutting part is extremely different, the blade is not sharp and the surface is rough.
The hinged cutting blade is too wide.
The flow is not smooth during reheats.
Evergreally Wear.
The hinge hit the wound and the blade had a burr or bail.
There is a dandruff tumor.
Due to the material relationship, it is not suitable for zero degrees front angle or negative RE front angle of the corner.
measure
Reduce cutting speed.
Select the cutting fluid according to the processing material.
Reduce the main partial corner and correct the sharpness of the blade.
Appropriate reduction in the amount of re-released pores.
Improve the position accuracy and quality of the reed pore front hole or increase the amount of rectus.
Repair the width of the blade.
Reduce the number of dental teeth according to specific circumstances, increase the crumb or return space with the blade angle, so that the crumbs are smooth.
Replace the reference heater regularly and grind the grinding area when the blade is grinded.
In the process of cutting, using and transporting, the reed should take protective measures to avoid dents.
For the hinge which was hit, it can be repaired by special oil stone or replaced the heater.
2
Inner hole roundness
reason
The length of re -re -re is insufficient and vibration is generated during hinge.
The hinged knife is too small.
The re-glued blade strip is narrow.
The hinge balance is biased.
There are gaps and cross holes on the surface of the inner hole.
The surface of the holes has sandy eye and stomach.
The main shaft bearing is loose, without a case facing toward the maric, and the gap between the puppet and the guide cover is too large, and the part is deformed due to the tightness of the thin part.
measure
The re-rigid re -blade can be re -Tooth -Not -To -Teethed re -splash.
Select Qualified Re-Blade to control the hole position tolerance of the pre-process. Use long and more precise guide cover without re-blade tooth distance; Choose a qualified rough.
When the tooth distance is more accurate, it should be adjusted in the spindle gap between the machine tool.
3
The center line is not straight
reason
The borehole in front of the reed is inclined, especially the pore diameter is small.
The main hinge corner is too big; the tips are poor, so the reduction of the reduction is easy to decorate the direction of the hinge.
The cutting part of the cutting part is too large.
The re-gap has moved to the middle of the intermittent gap.
When the hand rectus is too strong in one direction, forcing the Re-Labe to be sloping at one end, destroying the verticality of the Re-Labe.
measure
Increase the expansion of the pilot hole or process.
Reduce the main partial corner.
Adjust the appropriate recruitment.
There is a reef with a guided or extended cut section.
4
Pores increase
reason
The design value of the outer diameter size is large or the edge of the blade edge has burrs.
Cutting speed is too high.
Improper feeding or excessive processing waste.
The main hinge corner is too big; the rectification is folded.
Branch on the edge of the hinge edge.
When the blade is ground, the hinge mouth is too poor.
The selection of cutting fluid is not appropriate.
When installing the reloader, the cone handle surface is not wiped clean or the cone surface has a bump injury.
The flat tail bias of the cone handle is loaded into the tone handle of the machine tool and the cone interference of the cone.
The spindle is bent or the main axle bearing is too loose or damaged.
The hinge is not flexible.
Different shafts of the coin and hand paws are not uniform with both hands, so that the re-and right shake left and right.
measure
Reduce the outer diameter of the reference heater based on specific circumstances.
Reduce cutting speed.
Correctly adjust the feeding amount or reduce the processing amount.
Reduce the main partial corner.
Straightened re-re -re -re-rectarous cuts.
Use oil stones carefully to qualify.
The control Pioprer is within the allowable range.
Select the cutting fluid with better lubrication performance.
Before installing the re-installation, you must wipe off the oil pollution inside the pores of the reef and the main axis of the machine, and use oil stones to repair the light.
Repair the reference tail.
Adjust or replace spindle bearings.
Adjust the floating hair styling head and adjust the same axis.
5
There are edges on the surface of the inner hole
reason
The amount of housing is too great.
The back corner of the reduction piece is too large.
The hinged cutting blade is too narrow.
The workpiece area is too large and the main shaft is too large.
measure
Reduce the amount of reef.
Reduce the back corner of the cutting part.
Repair the width of the blade.
Choose a qualified rough.
6
Cut
reason
The length of re -re -re is insufficient and vibration is generated during hinge.
The hinged knife is too small.
The hinge strip is narrow;
There are gaps and cross holes on the surface of the inner hole.
The surface of the holes has sandy eye and stomach.
The main shaft bearing is loose, without a case facing toward the maric, and the gap between the puppet and the guide cover is too large, and the part is deformed due to the tightness of the thin part.
measure
Reduce cutting speed.
Select the cutting fluid according to the processing material.
Reduce the main partial corner and correct the sharpness of the blade.
Appropriate reduction in the amount of re-released pores.
Improve the position accuracy and quality of the reed pore front hole or increase the amount of rectus.
Repair the width of the blade.
Reduce the number of dental teeth according to specific circumstances, increase the crumb or return space with the blade angle, so that the crumbs are smooth.
Replace the reference heater regularly and grind the grinding area when the blade is grinded.
In the process of cutting, using and transporting, the reed should take protective measures to avoid dents.
For the hinge which was hit, it can be repaired by special oil stone or replaced the heater.
Q: Different from straight groove and spiral repeats?
A:
Spiral Groove:
Used for the hole.
There is a guaranteed film flow.
Smaller flow angle.
The ideal intermittent cutting choice.
Right groove:
Used for blind holes.
No dandruff.
Larger flow angle.
Vibration is reduced.
