Engraving machine tool recognition
1. Milling cutter: It is mainly a kind of milling tool for trimming the side of the workpiece. It is mainly used for vertical shaft milling, four-sided planing, double-end milling, and copy milling equipment.
Second, the tool structure: knife body + chip welding alloy head.
Third, the material description: knife body material - 45 # tool steel, 40Cr and other chip welding alloy head piece, the thickness is generally 3.2 and 4mm
Fourth, quality assurance: knife body material, alloy material, welding and processing technology (milling design, angle design, sharpening precision and dynamic balance processing).
V. Product classification: flower knife, flat knife, slotting knife, finger joint knife, door frame knife, door panel knife, wall board knife, floor knife, etc.
Sixth, the use of attention:
1. Clean the tool and the machine shaft before installation.
2. Pay attention to the cutting direction of the tool and the direction of rotation of the machine.
3. The combination knife adds a suitable gasket according to the processing needs and the tool condition.
4. The tolerance between the hole and the shaft is not more than 0.02mm.
5. There is no looseness after the tool is installed and clamped.
6, pay attention to safety protection cover the safety cover.
7. When feeding, the feed speed is uniform, and the appropriate processing speed is selected according to different processing materials and cutting amount.
8. Select the professional sharpening after the tool is passivated.
Seven, grinding requirements:
1. After sharpening: no blunt mouth, no small gap.
2. Ensure that the amount of grinding is consistent.
3. After the sharpening, the cutter keeps the original angle unchanged.
4. Select high-precision sharpening equipment and operate according to the regulations.
Eight, common problems:
1. The cross-section of the processed parts is large:
a) The machine tool is shaken.
b) The tool is not installed properly, such as: the installation is not in place, the end face has impurities.
c) The datum surface is not flat.
d) The feeding force is not uniform.
e) Tool jump tolerance is too large.
2. Reasons for the burning of processed parts:
a) The tool glue is heavy.
b) The pushing speed is too slow and the knife is too large and the machine speed does not match.
c) Tool passivation is severe.
d) The tool selection is unreasonable.
e) The tool angle design does not match the machined material.
3, the common problem of the combination knife - the reason is not tight, there are gaps (door frame knife, wall board knife, floor knife, combination slot knife, etc.):
a) The tool is not adjusted well, the gasket is not added properly or the tool selection is not matched.
b) The tool is not installed properly (there is slag inclusion in the middle or not installed in the proper position).
c) The tool design and machining dimensions are inconsistent with the actual machining.
