Common problems in the use of carbide 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 in strict accordance with the equipment instruction manual.

(2) Before the tool is installed, the debris on the spindle should be cleaned to ensure that the tool installation surface is clean and flat, and the tool safety cover must be installed.

(3) The matching tolerance between the inner hole of the tool and the main shaft of the equipment should be controlled within 0.03mm to ensure that the tool has no deformation and little vibration during the processing.

(4) Before installation, carefully check whether the tool has potential safety hazards, such as whether the blade has cracks or nicks, whether the welding is firm, whether there is abnormal wear, and whether the tool body is bent, twisted, cracked, etc.

(5) In particular, check whether the tool is installed in the correct direction and whether there is looseness after the tool is installed and clamped.

(6) After the tool is installed, conduct a test run first. If the tool swings greatly, it should be stopped immediately for inspection.

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

(8) The material should be fed at a constant speed during processing, and the appropriate feed speed should be selected according to different processing materials and cutting amounts, and the material should not be forced.

(9) The passivation degree of the tool should be observed at any time during the processing. If the wear of the tool tip reaches 0.2mm, stop using it immediately, and then use special equipment for grinding. injury accident.

(10) The use of the shaft sleeve must ensure that the inner hole tolerance is H7, the outer diameter is h6, and the parallelism tolerance is less than 0.02mm.

(11) During processing, the operator must wear protective glasses to prevent personal injury caused by broken tools and scattered fragments; gloves cannot be worn. If the female worker has long hair, she should put it in the work cap to prevent being caught in the machine. Dangerous; never touch the tool while it is running.

Detection of woodworking forming tools

(1) After the machining is completed, the tool should be checked for cracks or nicks.

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

(3) Carry out dynamic balance detection.

Frequently Asked Questions about Woodworking Forming Tools

(1) The cross-section of the workpiece is large. This problem occurs mainly for the following reasons:

The machine tool shakes greatly; the tool installation is unreasonable, such as the installation is not in place, there are impurities on the end face, etc.; the reference surface is uneven; the feeding force is uneven; the tool runout tolerance is too large.

(2) The processed parts are burnt. The main reasons for this problem are as follows: the pushing speed is too slow, the cutting amount is too large and the speed of the machine tool does not match; the tool passivation is serious; the tool selection is unreasonable; the tool angle does not match the processing material.

(3) The tool fit is not tight and there is a gap. There are several reasons for this problem: the tool is not adjusted properly, the gasket is not properly added or the tool is not matched; the tool installation is unreasonable (there is slag in the middle or it is not installed in a suitable position); the design size of the tool is different from the actual Manufacturing dimensions are inconsistent.
