The measurement deviation can use as the “correction amount” input program to finally repair the qualified tool.  

Lathe tool shape and usage Generally used tooltip types include the following: 1. Rough turning tool: it is mainly used to cut a large number of redundant parts so that the diameter of the work object is close to the required size. Surface luminosity is not important when rough, so the tooltip can be ground into a sharp peak, but the peak usually has a small roundness to avoid fracture. 2. Fine turning tool: the blade can be polished with the sharpening light of the whetstone, so as to produce a very smooth surface luminosity. Generally speaking, the round nose of the fine turning tool is bigger than a rough turning tool. 3. Round nose turning tool: can be used for many different types of work is a common turning tool when the grinding flat top surface can be left and right turning can also be used for turning brass. This turning tool can also form an arc on the shoulder corner, can also be used as a fine-tuning tool. 4. Cutting tool: only the end of cutting work, the tool can be used to cut materials and grooves. 5. Screw turning tool (tooth cutting tool): it is used for turning screw or nut.

CBN (Cubic boron nitride) is an abrasive second only to diamond in hardness.CBN grinding wheel has many advantages such as high grinding efficiency, high machining accuracy, long service life, etc. In particular, the application of the ceramic bond CBN grinding wheel greatly promotes the grinding process and is also very suitable for the grinding of bearing parts. How to achieve high-quality grinding of CBN grinding wheel, equipment, tools, materials, grinding conditions, grinding fluid, processing environment and other factors can not be ignored.  And is a good device for grinding CBN grinding wheel. The grinding capacity of ordinary grinding wheels (the cross-sectional area of grinding per unit time) is generally 1 ~ 3 mm3 / (mm·s). It adopts alumina or silicon carbide grinding grains with a hardness of 2,100 ~ 2,500hk. The strength of the binder that consolidates the grinding grains together is relatively low. Due to grinding force and self-sharpening, the grinding grains often break and fall off. The grinding capacity of the CBN grinding wheel is 1 ~ 15 mm3 / (mm·s), and the hardness of CBN grinding grains is 4700HK. High strength binders (ceramic binders) are used to consolidate CBN grinding grains together, and the incidence of grinding grains breaking or falling off is very low. Therefore, with the progress of processing, the surface state of the grinding wheel changes very little and the grinding precision can be maintained for a longer time.

The development of tools plays a very important role in the technical progress of human being. Throughout history, the development of tools has depended on the industrial revolution. As early as 28 BC to the 20BC in China, there have been a cone, drill and other copper tools. However, the performance of copper tools is not satisfactory. The rapid development of tools was in the late 18th century, with the development of steam engines and other machines. In 1969, carbide tools were produced by chemical vapor deposition at the Sandvik Steel Plant in Sweden. In 1972, Bosnia and Laguerre in the United States developed physical vapor deposition, in which they coated the tool surface with a hard layer of titanium carbide or titanium nitride. The surface coating method combines the high strength and toughness of the matrix material of the high hardness and abrasion resistance so that the tools have a better cutting performance. It was a revolution in the history of tools. Now, according to the needs of the development of manufacturing industry, multi-functional composite tools, high-speed and efficient tools will become the mainstream of tool development.In the face of more and more difficult to machining materials, the tool industry must improve tool materials. Research and development of new tool materials and more reasonable.

Recently BT150D CNC PCD& PCBN tool grinding machine designed and produced by Beijing Demina Precision Machinery Co., Ltd has been successfully accepted in Yantai City, Shandong Province, China. The customer there is very satisfied with the grinding effect of our machine. The customer purchased our machine for use of the big batch production of their company's PCBN tools. This effectively saved their labor cost and grinding time: for their standard tool grinding, it takes about 10 minutes for workers to finish it with a manual machine, but it only takes less than 5 minutes with our machine debugged. And it's very stable. This is not only one of the successful acceptance cases of our CNC machine in China. In recent years, the demand for CNC machine at home and abroad is increasing. This verifies the correctness of our development direction, because we have developed and produced CNC PCD& PCBN tool grinding machine since 2008, and have more than ten years of experience in this field. We believe that in the future our CNC machine will be imported to more countries and regions, to bring customers vital benefit there. Every staff of Demina will make his efforts for this goal.

The main task of PCD fine grinding is to control the final dimension precision of grinding accurately and stable.Wheel wear, accurate positioning of edge tip grinding point and grinding resistance will eventually affect the machining accuracy. These factors have nothing to do with the movement accuracy of the machine but are related to when to start  (that is, to the point of the tool setting), finish grinding and other issues and the monitoring of grinding state is closely related. Although wheel wear is difficult to measure and the height of the insert (which affects the position of the grinding point ) is difficult to measure within a certain range, the control system with the voice-activated device can easily record the exact position of the insert tip and the wheel surface at the moment of contact. Taking this as the starting point, the relative feed can guarantee dimensional accuracy. We call this  " tool setting method ".Of course, the premise of "tool setting method" is that the previous process has an accurate reference, or the dimension can be accurately measured before grinding. This can be done by CCD online measurement system. In the industry, when using the manual machine, the grinding process of the first back Angle of PCD tool (i.e. polishing edge) is as follows: on the basis of the dimension of rough grinding, grind  0.02~0.03mm further to form the blade of 0.05~0.1mm. This also happens to coincide with " tool setting method ".

Demina has devoted to developing the tool grinders for nearly twenty years, we have been improving our products all the time. Compared with other manufacturers, we have great confidence in our products. We draw some conclusions by making some comparisons with several manufacturers through the following aspects. Spindle Demina adopts motorized spindle with constant torque output. Torque output is large and uniform. Besides, radial and axial run-out are up to 0.002 to 0.003mm. As for other manufacturers, they adopt mechanical spindle and driving through the pulley. Its torque output is not uniform and there is vibration transmitted to the cutting edge and peak torque. Guide rail Demina adopts precision needle roller guide rail. While swinging by small range, friction is distributed, wear is uniform and torsion resistance is strong. Other manufacturers adopt ordinary cylinder roller guide rail, the diameter of the cylinder roller is large. Friction usually happens at the top and bottom of the roller and therefore elliptical cylinder forms after long-time swing. CCD support Demina adopts precision needle roller guide, which has zero clearance and smooth adjustment with a good feeling at the finger. Other manufacturers adopt ordinary dovetail guide, there is inevitably a gap. Adjustment with dry and stuck phenomenon often makes finger "ache" and is easy to make the image "run out". Marking line The electronic marking line of Demina is clear and high precision. Each marking line can adjust separately at the speed of 0.01mm/time and the line width will not change when the image is amplified. Other manufacturers adopt glass marking the line. Its scale is discontinuous and precision is not high. The line width will become "thicker" when the image is enlarged and the "line" is not accurate.
