Abstract

The invention discloses a cutting method of VCM magnetic steel. The cutting method comprises the steps of vertically bonding a VCM magnetic steel blank to a bonding tool; fixing the bonding tool and the VCM magnetic steel blank in a multi-wire cutting machine; cutting the VCM magnetic steel blank which is vertically fixed; and taking out the VCM magnetic steel formed by cutting. The invention alsodiscloses the bonding tool. According to the cutting method of the VCM magnetic steel, an existing horizontal fixed re-cutting mode is replaced with a vertical fixed re-cutting mode, and the problemsof large cutting allowance, material waste, low sheet yield, high production cost and low precision of an existing cutting scheme are solved.

Description

Technical field [0001] The invention relates to the technical field of metal processing, in particular to a method for cutting VCM magnetic steel. It also relates to a bonding tooling. Background technique [0002] At present, the voice coil motor (VCM) magnet adopts the cutting plan of a multi-wire cutting machine. After cutting, the thickness tolerance of the sheet exceeds the customer's requirement of ±0.01mm. The processing process of a grinder must be added to ensure the sheet thickness tolerance. This requires the cutting margin of the blank to reserve 0.05-0.07mm per piece, which greatly increases the production cost. [0003] The existing VCM magnetic steel cutting scheme has disadvantages: large cutting margin, waste of material; low sheet ejection rate of a single piece of blank material; need for grinding machine processing procedures, high production cost. [0004] Therefore, how to provide a VCM magnetic steel cutting method that guarantees tolerances after multi-wire ...
