BT-150H Diamond Tool Grinder Technological Breakthroughs1.The optimization of the vertical axis: the micro-adjustment of the vertical axis lift integrated into the workbench fixture, greatly enhance the stability and rigidity of the equipment.2. More stable feed: PCD is a hard brittle material, can not withstand the impact (especially periodic), so our company’s improved machine tool design with air pressure “flexible feed” device. In the tool blade by the impact of the knife function, effectively improve the roughness of the blade.3. A large screen is used to display the data and tool images of each coordinate, which is located directly in front of the operating station. It is not necessary to frequently twist the head and raise the head.4. Spindle Angle: by the servo motor “on line” control, one, two back Angle grinding in one go, but also because of the online control “automation” adjustment. Avoid the “artificial” error caused by manual adjustment, precision, efficiency has been improved.5. Grinding wheel integrated design: the previous tool grinding, coarse grinding, fine grinding is done on the independence of two grinding wheels, grinding or when a batch of cutting tool replacement after all coarse grinding tool first grinding, fine grinding wheel to continue or every clamping tool to rotate a coarse and fine grinding wheel, the former is of high efficiency but second clamping error exists, the latter high precision but low efficiency. Now, after innovation, the thick and fine grinding wheels are organically combined into “one grinding wheel”, with rough and fine inside, high inside and low outside. During grinding, only change the tool without changing the grinding wheel. Since the coarse and fine grinding wheels are “combined”, either party can be replaced separately when reaching the service life limit. That is, the thick and fine grinding wheels can work to their service life limit, and there is no “waste” of grinding wheels.
Drills resharpening by 5-AXIS tool grinding machine
1. Check whether the drill bit is bent or not, and whether the knife orifice is intact.
2. Hold one hand in the front part of the center of the drill bit, and use this hand as the 0 point, above the middle of the grinding wheel of the grinder.The other hand holds the end of the drill bit and moves up and down.
3. Thus grinding the two edges of the drill bit.Notice that the two cuts are the same length, you can use a ruler.You can see it when you are familiar with it.Also note that the center line of the drill bit and the edge of the Angle should be about 45 degrees.
4. After the measuring edge is worn, it can be seen from the figure above that the center of the drill bit is a knife edge perpendicular to the center line of the drill bit. This knife edge blocks the downward movement of the drill bit when drilling, and has a large contact surface with the processed parts, causing the slide of the drill bit and changing the drilling position.To this end I do as follows
5. On another specially designed slotted grinder, grind the transverse edge perpendicular to the middle line of the drill bit to a point, which is my ingenious treatment.
6. When you look down from the head of the drill, you can see that I have sharpened the two edges of the drill into four edges.It's pointed in the middle.That's the advantage.During drilling, the bit is stable, the resistance is small, the positioning contact surface is small, and the hole is round.
7. Put into use.The iron shavings are formed, the bit wobbles less, and the perfect bit is ground.
1. A bit grinder is a swinging bit up and down, not a rotating bit.
2, reduce resistance, stability is the position and maintain the size of the same principle.
3, pay attention to the grinder injured hand.
4. Don't feed too much at the beginning.Be consistent at all times.

Adjustment method of grinding machine
When we use the sharpener, we must first adjust the high-quality APE-40 UP- sharpening machine. Let's talk about the adjustment method of the sharpener.
Use the feeler gauge to measure the full length of the sharpening machine. At this moment, the oscillating flywheel makes the upper turret move up and down several times. Gradually tightening the bolts, nuts, and the gap value of the aligning cutting edge to reach the required stop. Adjust the other one without adjustment and adjust the knife-edge of the sharpener to zero. At this time, we have made fine adjustments to ensure that the three wires can not enter into the five wires. The grinding machine has a large number of the inorganic body, task table, electromagnetic table, grinding head, and electric appliance. The structure between the parts is compact, and the grinding head is evenly shaken. The equipment has the precision shaking, high efficiency and long operation time. Features, it is used in the processing of a variety of straight edge tools.
When arranging the sharpener, adjust it from the beginning with a feeler gauge. The has different cutting gaps for various thicknesses.
Operation precautions of sharpening machine
It is easy to use the automatic knife sharpener to sharpen the blade. You can use a variety of different grinding wheels to grind the woodworking blade. What should we do when sharpening? What should I pay attention to?
Should calibrate APE-40 semi-auto drill grinder grinding wheel and then tightened to the end of the grinding wheel. The abrasive turning should correct. When the effective radius of the abrasive is worn to 1/3 of the original radius, the new abrasive should be replaced in time. When the knife is sharpened, the amount of feed should not be too large. Generally, it is controlled between 0.01-0.02mm. If the feed amount is too large, the blade and the heat will be too high to deform the blade, so that the edge of the blade will not be in a straight line.
When grinding the main flank, the main declination and the main relief angle should ground. When grinding the flank, the secondary declination and the secondary relief angle should be ground at the same time. When grinding the back, the rake angle should be ground at the same time.
In the process of sharpening the sharpening machine, we must pay attention to the safe operation. Pay attention to the details such as whether the grinding wheel is cracked or the grinding wheel shaft nut is tightened, etc., to prevent problems during use.
