Using abrasive abrasive density, by determining the density distribution of the abrasive on the abrasive to solve the problem

Bending and forming method using the high-speed grinding parabolic parts, due to the non-uniform abrasive wear of the abrasive require frequent trimming. For this process the problem, the use of fixed  Diamond blade  controllable density distribution of this feature, by determining the density of abrasive grinding at different locations on the distribution to solve this problem. Consider the workpiece from the initial processing to the sphere in the process of removal of the paraboloid and to  cubic boron nitride the mathematical model and the ideal state derived abrasive density trend. Bending theory expounded abrasive and grinding tools, design, detailed synthetic diamond  of the abrasive abrasive on uneven density distribution method. The use of such non-uniform distribution density abrasive grinding test results are analyzed and the theoretical calculation of worn grinding parabolic profile shape error, the same as the general conditions using abrasive uniform density results.

Wood cross section of machines are not moving, reciprocating saw blade

Wood processing enterprises cross saw one of the devices of its generic basic requirements are: high productivity and good cut quality, simple structure, easy to operate security. Machines are generally transverse section wood does not move, the blade  cutting tools . Width difference according to the thickness of timber, required travel time adjustable blade, the blade forward speed controllable time in order to  abrasive grinding , return speed should be greater than the forward speed. Case of extraordinary circumstances (eg sudden increase cutting resistance, clip saws, etc.), the saw blade feed rate can always be reduced or stopped automatically. In addition, cross saw assistive devices should be perfect, with a wood segment to  polycrystalline diamond  feeding, pressing and releasing, etc. shirk action to the eventual realization of the entire truncation mechanization and automation. Most simple cross cross cut saw is hanging chain saws, circular saw blades and its hindquarters moving motors are mounted on pivoting hanger. aircraft structure is simple, flexible, but labor-intensive, nor safe, it is generally except for the other jobs outside the star out and are already in the process of transformation.

Longitudinal acceleration roll sets, plates for longitudinal movement will quickly

Saw composition, mainly by the lateral chain saw saw table, two cut-off saws agencies, longitudinal acceleration roll stations and length bodies and other components. Its working principle is: After sorting station after sorting lumber, delivered by a  polycrystalline diamond conveyor chain saws cut the machine table, driven by the conveyor chain, first through the "saw cut head, and then into the longitudinal  Abrasive grinding wheel  sets, plates will quickly make longitudinal movement across the buffer plate after plate still horizontal lateral movement forward chain drive operator in the moving plate, cut to length for sheet length, sheet through the "cut-off saws saws completed, then, the specification sheet by the cut-off saws bench conveyor conveyor transported to the timber shipped out.

Connected to a transverse chain conveyor

Continuous two blade saws (hereinafter referred to as Saw) is to achieve continuous saws cut wood, so that continuous  abrasive wheels operations, mechanization of the host device. The sawing lumber is to learn foreign advanced technology, combined with China's situation and design, this device has been used in China, the Canadian  grinding wheel  comprehensive intensive technical cooperation project - an annual output of  lining  cutting tools  workshop, workshop production process in sorting station is connected with the lateral chain conveyors afterwards. After more than four years of production practice, and achieved satisfactory results. Also our lumber production to achieve continuous production of sawn cut first.

Self-bucking machine in Wood Landing applications, can also be applied in the lumberyard

Article saw the original logs cut into standard machinery. Of portable, self-propelled and fixed three kinds. Portable bucking machine is essentially a portable chain saws, used in the cutting area are bucking Chainsaws (see gasoline powered chain saws), used in the lumberyard bucking a chainsaw (see electric chain saws).  polycrystalline diamond in Wood Landing applications, can also be applied in the lumberyard. Fixed bucking machine is  Synthetic diamond . China is the most widely  cutting tools bucking saws, 1965 started using fixed bucking machine, but few in number. Self-bucking machine in the late 1950s, the emergence of a new type of North American forest machinery.

Fillers curing light curing resin abrasive properties of

By analyzing the classical theory of the mechanism of adhesion, for the light-curing resin is characterized, discusses a photocurable resin for binding the abrasive mechanism, respectively, from two angles of  cutting tools particles and a binder made ​​a series of  cubic boron nitride  with light-curing resin abrasive performance measure. Studied the light-cured resin bonded abrasives curing mechanism. Analysis of the diamond abrasives and other fillers curing light curing resin abrasive  polycrystalline diamond , and then select the light-cured resin blade as the research object, the blade curing mechanism is analyzed and modeled by the model experiments verified. Finally inside the light curing resin abrasive light quantity distribution discussed.

Compression performance and other aspects of bending properties were studied

Using light-cured resin as a binder resin abrasive manufacture is rapid prototyping of new technology in the field of manufacturing abrasive new applications, this light-cured resin bonded abrasives, several key technologies in-depth study. Studied the light-cured resin bonded abrasives binding agent performance.  polycrystalline diamond filler particle size and concentration as well as different types of light curing resin  cutting tools hardness, tensile properties,  Diamond blade  properties and other aspects of the bending properties were studied. In addition, the light curing resin abrasive glass transition temperature, and the temperature of the filler was discussed. Studied the light-cured resin bonded abrasives binding mechanism.
