Abstract

PROBLEM TO BE SOLVED: To provide a method to remove burr produced on an edge part simultaneously while working at the time of working a fine groove for an oil sump on a cylinder bore, etc., of an engine by a slicing blade. SOLUTION: A CBN slicing blade 10 is about 0.03 mm in thickness dimensions and works a fine groove 30 on a work 20. A grinding liquid supply device 100 has a grinding liquid tank 110 and an abrasive grain tank 130, and a mixing device 150 mixes abrasive grains K1 in grinding liquid W1. The abrasive grains K1 have a grain diameter of 3-5 μm and those in quantity of 20-40% in a volume rate against the grinding liquid W1 are mixed. The abrasive grains in the grinding liquid to be supplied to a working part are circulated in association with the slicing blade 10 and remove burr produced on an edge of an inlet of the fine groove 30.
