Problems solved by technology

[0002] In the prior art, in order to improve cutting rigidity and cutting quality, a diamond deposition layer is usually coated on the blade substrate, and the diamond particles in the diamond deposition layer are all the same in size and are single. Usually, diamond and nickel-based coatings Diamond is fine-grained diamond, and the cutting accuracy of the blade is high, but it is easy to break and has a short service life. The substrate must reach a certain thickness to be difficult to break. Fracture, but the cutting accuracy is not high

Embodiment 1

[0023] The composition of the electroplating solution and the diamond content are as follows:

[0024] The components of the nickel-based electroplating solution include 350 g / L of nickel sulfamate, 30 g / L of boric acid, 7.5 g / L of nickel chloride, 0.5 g / L of 2 μm diamond, and 0.3 g / L of 30 μm diamond.

[0025] A preparation method of a composite diamond ultra-thin nickel-based blade: comprising:

[0026] 1. Add 0.5g / L of 2μm diamond particles per 1L of nickel-based electroplating solution in the plating tank, and stir continuously through the electric stirring blade installed at the bottom of the plating tank, so that 2μm diamonds are evenly distributed in the nickel-based plating solution in the plating tank middle;

[0027] 2. Put the qualified matrix prepared by machining into the fixture for pretreatment, and put it into the electroplating tank after completion, and use 1.5A current for electroplating. During the electroplating, add 0.3g / L 30μm diamond particles per hour...

Embodiment 2

[0035] Embodiment two: electroplating solution composition and diamond content are as follows:

[0036] The components of the nickel-based electroplating solution include 400 g / L of nickel sulfamate, 35 g / L of boric acid, 15 g / L of nickel chloride, 0.5 g / L of 3 μm diamond, and 0.3 g / L of 30 μm diamond. Test: With the spindle speed of the cutting machine at 30.0K / min, the feed rate at 30mm / s, the cutting blade wear of PCB material is 7μm / 1km (the outer diameter of the blade consumes 7μm per 1km of cutting material), and the edge jumping is 12μm.

Embodiment 3

[0037] Embodiment three: electroplating solution composition and diamond content are as follows:

[0038] The components of the nickel-based electroplating solution include 350 g / L of nickel sulfamate, 30 g / L of boric acid, 7.5 g / L of nickel chloride, 2 g / L of 3 μm diamond, and 0.3 g / L of 30 μm diamond. Test: The spindle speed of the cutting machine is 30.0K / min, the feed rate is 20mm / s, the cutting PCB material blade wear is 5μm / 1km, and the cutting edge is 10μm.

Abstract

The invention provides a composite diamond ultra-thin nickel-base blade and a preparing method thereof. The method comprises the steps that 0.1-4 g / L of 1-8um diamond particles are added into every 1 L of nickel-base electroplating solution in a plating tank, electric stirring vanes arranged on the bottom of the plating tank are stirred without stop, and therefore 1-8um diamonds can be distributed in the nickel-base electroplating solution in the plating tank uniformly; qualified base bodies prepared through machining are added into a clamp to be subjected to pretreatment, after pretreatment is completed, the base bodies are placed into the electroplating tank, 1.5A currents are adopted for carrying out electroplating, in the electroplating process, 0.1-1 g / L of 10-50um diamond particles are added every one hour, the electric stirring vanes carry out high-speed stirring, electroplating is carried out for 4 hours, and therefore the 1-8um diamond particles and the 10-50um diamond particles adhere to the surfaces of the base bodies to form diamonds and nickel-base plated layers. The fine diamond particles and the coarse diamond particles are prepared according to the different proportions, the cutting strength, and the rigidity and the cutting quality of the blade are improved greatly to meet cutting requirements of the different materials.
