Workpiece defect Cause and removal method
PPFD is a key factor in the detection of Plant Growth Light. Optical quantum flux density (PPFD) refers to the luminous flux density in photosynthetically active radiation. Most Plant Growing Lamp on the market that can achieve an average PPFD of 2000 μmol/m²/s have a power of 600W, while Litehome's Plant Light just only need 200W. Can greatly reduce your electricity bills.
With lower production costs, your products will have more advantages. This is why you should choose litehomeLED Plant Grow Light.

2) The workpiece is poorly clamped, and the tip of the tailstock and the center hole of the workpiece are too tight.
3) The tool geometry and cutting amount are not properly selected, resulting in excessive cutting force. It can reduce the depth of cut and increase the number of feeds.
4) Thermal deformation occurs during cutting. Cooling lubricant should be used.
5) The distance between the tool tip and the support block is too large. Should not exceed 2mm Bamboo shape 1) After adjusting and grinding the support block with the tool holder, the connection is not good, so that the radial dimensions of the second and first feeds are inconsistent, causing a stroke diameter that coincides with the width of the support block over the entire length of the work. Variety. When a slight bamboo shape occurs in the cutting, the pressing force of the upper supporting block can be adjusted, and the middle carriage handle can be adjusted to change the cutting concentration or reduce the gap between the large pallet and the middle carriage.
2) Adjusting the outer support block of the tool holder too tightly, it is easy to change the periodic diameter in the middle part of the workpiece, and the compression should be adjusted to keep the support block in good contact with the workpiece. Polygon 1) The tool holder support block is in poor contact with the workpiece surface, leaving a gap to make the center of the workpiece deviate from the center of rotation. The structure of the tool holder should be reasonably selected, and the curved surface of the support block should be properly ground to make good contact with the workpiece.
2) The workpiece yaw caused by various factors such as clamping and heating, resulting in a change in cutting depth. Use brackets and improve contact between the bracket and the workpiece Taper 1) The tailstock tip is not parallel to the spindle centerline to the bed rail.
2) Tool wear. Grinding the radius of the tool nose with a 0° back angle rough surface 1) Vibration during turning.
2) The material of the tool holder support block is improperly selected, and it is in contact with the workpiece and the friction is poor.
3) Tool geometry parameters are not properly selected. The radius of the tool nose can be ground. When the length and diameter of the workpiece are relatively large, the wide blade low speed light car can also be used.
