BASICRA tools refer to implements used in woodworking. They generally have sharp cutting edges, so safety must be prioritized during use. Frequent sharpening is required, especially for plane blades and chisels, which must be kept sharp to ensure ease of use and quality, as the saying goes, "sharpening the axe will not delay the job of chopping wood." Woodworking tools are categorized into power tools, pneumatic tools, and hand tools. Power tools can be divided by function into multi-function tools (such as multi-tools) and single-function tools (such as electric planers, jigsaws, circular saws, sanders, and engraving machines); pneumatic tools include polishers and nail guns; hand tools can be divided into measuring tools, hand saws, woodworking planes, wood files, hand chisels, and sandpaper.

BASICRA tool classification

1) Squeeze-exhaust suction cups expel all air from the cup by downward squeezing force, creating a negative pressure state inside to hold the workpiece. Advantages include simple structure, light weight, and low cost. However, the suction force is not large, so they are mostly used for workpieces that are not too large in size, thin, and light. 2) Airflow negative pressure suction cups use an airflow control valve to inject compressed air from an air pump through a nozzle, forming a high-speed jet that removes air from the suction cup cavity, creating negative pressure to hold the object. If compressed air is available at the worksite, using this type of suction cup is convenient and low-cost. 3) Vacuum pump exhaust suction cups use an electromagnetic control valve to connect the vacuum pump to the suction cup. When the control valve evacuates air, the air in the suction cup cavity is removed, creating negative pressure to hold the object. Conversely, when the control valve connects the suction cup to the atmosphere, the suction cup loses suction and releases the workpiece. The suction force of vacuum pump suction cups mainly depends on the size of the suction area and the degree of vacuum in the inner wall of the suction cup (referring to the thinness of the air in the inner q cavity). This type of suction cup is reliable and has strong suction, but it requires a vacuum pump and an airflow control system, resulting in higher costs. 4) Mechanical clamping: Structure of a straight-bar dual-cylinder translational gripper. The gripper fingers are mounted on a straight bar equipped with finger mounting seats. When pressurized gas enters the rod-side chambers of the single-acting dual cylinders, the two pistons move toward the center, clamping the workpiece; when no pressurized gas enters, springs push the two pistons outward, releasing the workpiece. To ensure synchronous movement of the two pistons, a flow divider valve is installed in the cylinder intake line. This type of end effector is used in loading and unloading assembly workstations.

BASICRA tool precautions

Large saws are commonly used for wide and thick boards; small saws are commonly used for narrow and thin lumber; coarse-toothed saws are commonly used for cross-cutting; fine-toothed saws are commonly used for tenon heads and shoulders; saws with greater set are required for hardwoods and wet wood, while saws with less set are required for softwoods and dry wood. When using saws, safe operating procedures for each type must be observed: 1) Before using a frame saw, adjust the blade angle with the knob; conventionally, it should form an angle of 45° with the plane of the wooden frame. Tighten the tension rope with the toggle to keep the blade taut and straight. When starting the cut, hold the saw handle firmly with the right hand and place the left hand at the starting point, gently pushing and pulling a few times. Do not apply excessive force; do not twist the saw left or right during cutting. Apply heavy pressure on the forward stroke and light pressure on the return stroke, maintaining a uniform rhythm. Hold the part being cut off steady with your hand as the cut nears completion. After use, loosen the blade and hang it in a secure location. 2) When using a crosscut saw, apply balanced force with both hands to prevent the saw from drifting toward the side with greater force. When correcting a skewed cut, do so slowly to prevent binding or breaking the blade. 3) When using a coping saw, do not apply excessive force or pull too quickly, to avoid breaking the wire blade. During sawing, the operator's head must not be positioned above the upper end of the bow frame, to avoid facial injury from a snapping wire. 4) Regularly check the sharpness of the blade and the stability of the saw frame and handle. Promptly repair blades with dull or uneven teeth. Repair or restore damaged ropes, nuts, knobs, handles, and wooden frames before continuing use.

BASICRA tool usage

1) When placing the diamond dressing tool tip into the holder, avoid impacting the grinding wheel surface. 2) Do not align a single-point diamond dressing tool tip vertically with the center of the grinding wheel; it generally needs to be tilted by 10-15°. 3) Do not "quench" (suddenly cool) a heated dressing tool. During dry dressing, maintain sufficient interval time between dressings to allow the heated dressing tool to cool. 4) Do not assume the grinding wheel surface is ideally flat. At the start of dressing, locate the high spots on the grinding wheel and perform dressing. 5) If possible, the material removal amount per dressing should not exceed 0.001 inches on the radius of the grinding wheel. Excessive removal can cause premature wear and frequent fracture of the diamond dressing tool tip. 6) However, do not remove too little material each time. Grinding wheels used on old or low-rigidity machine tools may not require dressing. 7) Note that the dressing tool should not remain in one position for too long. This will polish the grinding wheel surface, generate high temperatures, and damage the diamond dressing tool. Rotate the dressing tool at least once daily. 8) Do not continue to use worn or damaged dressing tools. Adjust or replace them promptly. 9) Do not select excessive removal amounts and fast lateral feed rates during rough dressing, followed by small removal amounts and slow lateral feed rates during finish dressing. This will quickly damage the diamond dressing tool. If possible, it is recommended to select the same lateral feed rate for both rough and finish dressing.
