Common problems in the use of hard alloy forming tools

Installation and debugging of woodworking forming tools

(1) Ensure that the processing equipment is in good condition, the spindle is free from deformation and vibration, and operate strictly in accordance with the equipment manual.

(2) Before installing the tool, the debris on the spindle should be cleaned to ensure that the tool installation surface is clean and flat. It is necessary to install a tool safety cover.

(3) The fit tolerance between the inner hole of the tool and the equipment spindle should be controlled within 0.03mm to ensure that the tool does not deform and has low vibration during the machining process.

(4) Before installation, the cutting tool should be carefully checked for any safety hazards, such as cracks or notches on the blade, firm welding, abnormal wear, and bending, twisting, or cracking of the tool body.

(5) Special attention should be paid to checking whether the installation direction of the tool is correct and whether there is any looseness after clamping the tool.

(6) After the installation of the tool is completed, conduct a trial run first. If the tool swings excessively, stop the machine immediately for inspection.

(7) Suitable gaskets should be added to the combination tool according to the processing needs and tool conditions.

(8) During processing, the material should be fed at a uniform speed, and an appropriate feed rate should be selected based on different processing materials and cutting amounts. Forcible pushing of the material is not allowed.

(9) During the machining process, the degree of passivation of the cutting tool should be observed at all times. If the wear of the tool tip reaches 0.2mm, it should be immediately stopped and then repaired with specialized equipment. Forcible use can easily cause damage to the cutting edge, fracture of the tool body, and even personal injury accidents.

(10) When using a shaft sleeve, it is necessary to ensure that the tolerance fit of its inner hole is H7, the outer diameter is H6, and the parallelism tolerance is less than 0.02mm.

(11) During processing, operators must wear protective glasses to prevent personal injury caused by tool damage, flying debris, etc; Gloves cannot be worn. If a female worker has long hair, it should be placed inside the work hat to prevent danger from being drawn into the machine; It is absolutely forbidden to come into contact with the cutting tool during operation.

Testing of Woodworking Forming Tools

(1) After machining, the tool should be checked for cracks or notches.

(2) Use a dial gauge and a runout detection device to check whether the runout tolerance of the cutting tool meets the design requirements.

(3) Perform dynamic balance testing.

Common problems with woodworking forming tools

(1) The machined part has large cross-sectional patterns. There are several main reasons for this issue:

The machine tool has large shaking; Improper installation of cutting tools, such as inadequate installation and impurities on the end face; Uneven reference plane; Uneven feeding force; The tool runout tolerance is too large.

(2) Processed parts are burnt. There are several main reasons for this problem: slow pushing speed, large cutting amount, and mismatch between machine speed; Severe tool passivation; Unreasonable tool selection; The tool angle does not match the processing material.

(3) The tool does not fit tightly with gaps. There are several main reasons for this problem: the tool is not adjusted properly, the gasket is not added properly, or the tool selection is not matched; Improper installation of cutting tools (slag inclusion in the middle or not installed in a suitable position); The design size of the cutting tool is inconsistent with the actual manufacturing size.
