Novel machining technology for grinding plunger

Abstract

The invention relates to a novel machining technology for grinding a plunger. The novel machining technology comprises the following operation steps of step one, machining the outer circle of the plunger; preparing workblank, roughly grinding the outer circle of the workblank, buffing the roughly-ground outer circle, and finally, finely grinding the outer circle; step two, carrying thermal treatment on the plunger of which the outer circle is machined; step three, machining a straight channel in the plunger on which the thermal treatment is carried out by adopting a CNC (Computer Numerical Control) grinding machine; step four, machining a chute in the plunger by adopting the CNC grinding machine after straight channel machining is completed, carrying out one-step clamping, and automatically overturning one surface which is already machined to machine the other surface. The novel machining technology disclosed by the invention is low in production cost and excellent in product quality.

Description

technical field [0001] The invention relates to a novel machining process for plunger grinding. Background technique [0002] At present, in the domestic diesel mechanical pump plunger pair processing industry: the plunger outer circle processing generally adopts the following process: blank → rough grinding outer circle → fine grinding outer circle → smooth grinding outer circle → fine grinding outer circle (with grinding pair) , there are many cylindrical grinding processes, and the process route is long; the cylindrical straight groove of the plunger is generally used for milling with a milling cutter before the heat treatment of the part (the hardness of the part is low); the cylindrical chute of the plunger is generally used After heating, use a corundum grinding wheel to grind on the M7120D surface grinder. The dust in the workplace is very harmful to employees. Contents of the invention [0003] Aiming at the shortcomings of the above-mentioned existing production ...
