Whetstone (also known as honing) finishing surface finishing process embedded in the Block Honing head. Also known as a honing. 5 to 500 mm diameter main processing even greater variety of cylindrical holes, hole depth to aperture ratio of up to 10 or more. Workability under certain conditions, also flat, cylindrical surface, spherical surface, the tooth surface. Honing head peripheral set with a length of 2 to 10 approximately hole length of 1/3 to 3/4 of the whetstone, in the heng holes both rotary motion and reciprocating motion, through the honing head in the spring or hydraulic control at the same time the uniform outside rose, Therefore, the larger surface contact area with the hole, the processing efficiency is high. Honing after the size of the hole accuracy of IT7 ~ 4 level, and the surface roughness of up to Ra0.32 ~ 0.04 microns. Camshaft Grinding the size of the margin, depending on the aperture and the workpiece material, the general iron pieces of 0.02 to 0.15 mm, the steel of 0.01 to 0.05 mm. The rotational speed of the honing head is generally 100 to 200 rev / min, reciprocating movement speed is generally 15 to 20 m / min. Chips and abrasive rushed to improve the surface roughness and reduce the temperature of the cutting zone, the operation often requires large amounts of cutting fluids, such as kerosene or increase a small amount of spindle oil emulsion, sometimes with extreme pressure.
1, extrusion honing machine: used to clamp parts and fixed to a predetermined position, apply squeezing pressure on the grinding abrasive. Extrusion honing machine has two opposed abrasive cylinder, closed clamping parts or fixtures, the abrasive grinding pushed from one cylinder to another cylinder, parts of the site are constrained to produce abrasive, good trip through the pre-adjusted honing position and I set the number of parts polishing, pour Park corner. Extrusion Honingmachine is simple, convenient adjustment, multi-function, etc.. 2, grinding Abrasive: used to produce machine parts to be passed to the extrusion pressure polishing, deburring inverted rounded corners on the surface, and through the movement of parts for abrasive polishing. Abrasive grinding abrasive indicators include viscosity, abrasive type and particle size. Abrasive grinding can be divided according to the viscosity D, DZ, ZG, G abrasives different viscosity. Because different viscosity abrasive flow generated can be divided into light integer (ie polished type), inverted angle-park, light integer abrasive. 3, honing machine fixture: for the workpiece fixed to a predetermined position, and guiding the abrasive flow on the specified channel, and thus the work surface polishing or inverted rounded corners. In small batch production jig is usually quite simple, once in mass production should be designed several of the workpiece clamping fixture. Fixture materials: aluminum alloy, cold rail steel and non-metallic materials nylon. 4, the workpiece cleaning: abrasive media itself as a strong cohesion, an objective which has non-stick properties of the metal. After machining, the workpiece can be easily hand stripped down 98 abrasive. These are stripped down to close up the abrasive for reuse, residual abrasive ultrasonic vibration or compressed air or gas can be cleaned Ex.
