The wheel frame can be fed in a straight direction. The gear to be ground is supported by the indexing frame and the tailstock, and is longitudinally reciprocated through the table to grind the tooth surface, and the indexing is performed after each tooth is ground. On a machine with a helical gear, the grinding wheel can be rotated one point according to the helix angle of the workpiece, and the workpiece can be additionally converted in the reciprocating motion.
If the machine wheel holder enables the grinding wheel to enter the internal gear workpiece, the internal gear can be ground. The forming wheel grinding machine has a simple layout, high efficiency and 5 precisions. It is suitable for batch production. The grinding wheel of the forming wheel grinding machine processed by the forming method is shaped into a tooth shape by the forming wheel dresser in the axial section. It is especially suitable for gears with a small number of teeth. When the grinding head of the gear grinding machine advances and retreats, the speed is uneven or there is an impact phenomenon. The hydraulic speed regulating valve is faulty, and the speed regulating valve is removed to clean or replace. The solenoid valve is out of order, removed, cleaned or replaced. If the guide rails are not parallel, loosen the adjustment screw and adjust again.
The angular velocity imbalance of the gear grinding machine is that the corner speed is too small or the corner force is too fast, causing the corner swinging impact force to be too loud, and the positioning cylinder pressure is too large, and the throttle valve should be adjusted. The set flow rate of the right and left swing throttle valves is not appropriate, and the throttle valve should be adjusted.
To select the saw blade suitable for the saw blade grinding machine from the aperture and thickness:
1, the choice of aperture
The aperture is a relatively simple parameter, mainly selected according to the requirements of the equipment, but in order to maintain the stability of the saw blade, the saw blade zuii above 250MM is better to use a device with a larger aperture. At present, the diameter of standard parts designed in China is 20MM holes for 120mm and below, 25.4MM holes for 120-230MM, 30 holes for more than 250, and 15.875MM holes for some imported equipment. The mechanical aperture of multi-chip saw is relatively complicated. There are many keyways to ensure stability. Regardless of the size of the hole, it can be modified by a lathe or wire cutter. The lathe can be placed in a large hole in the car, and the wire cutter can be reamed to meet the requirements of the equipment.
2, the choice of thickness
The thickness of the saw blade theoretically we hope that the thinner the saw blade, the better, the kerf is actually a kind of consumption. The material of the alloy saw blade base and the process of manufacturing the saw blade determine the thickness of the saw blade, the thickness is too thin, and the saw blade is easy to shake when working, which affects the cutting effect. The thickness of the saw blade should be chosen from the stability of the saw blade work and the material being sawed. The thickness required for some special-purpose materials is also specific and should be used as required by the equipment.
