Embodiment 2

[0034] A hard alloy surface treatment process, comprising the steps of:

[0035] Step 1: Put the cemented carbide in the ultrasonic generator for 5 minutes to remove wax and oil.

[0036] Step 2: Check the working status of the grinding machine again, and turn on the grinding machine for two minutes. After confirming that the grinding machine is working normally, turn off the grinding machine, and then place the cemented carbide processed in step 1 on the grinding part of the grinding machine, and turn on the grinding machine to clean the surface of the cemented carbide. Grinding treatment is carried out so that the convex points on the surface of the cemented carbide are polished clean.

[0037] Step 3: Fix the cemented carbide polished in step 2 with limit bolts, rinse the surface of the cemented carbide with water, the water pressure is 50 kPa, the water impact time is 45 seconds, and the distance from the nozzle to the surface of the cemented carbide is 50 mm, clean the d...

Embodiment 3

[0045] A hard alloy surface treatment process, comprising the steps of:

[0046] Step 1: Put the cemented carbide in the ultrasonic generator for 7 minutes to remove wax and oil.

[0047] Step 2: Check the working status of the grinding machine again, and turn on the grinding machine for two minutes. After confirming that the grinding machine is working normally, turn off the grinding machine, and then place the cemented carbide processed in step 1 on the grinding part of the grinding machine, and turn on the grinding machine to clean the surface of the cemented carbide. Grinding treatment is carried out so that the convex points on the surface of the cemented carbide are polished clean.

[0048] Step 3: Fix the cemented carbide polished in step 2 with limit bolts, rinse the surface of the cemented carbide with water, the water pressure is 50 kPa, the water impact time is 50 seconds, and the distance from the nozzle to the surface of the cemented carbide is 55 mm, clean the d...

Embodiment 4

[0056] A hard alloy surface treatment process, comprising the steps of:

[0057] Step 1: Put the cemented carbide in the ultrasonic generator for three minutes to remove wax and oil.

[0058] Step 2: Check the working status of the grinding machine again, and turn on the grinding machine for two minutes. After confirming that the grinding machine is working normally, turn off the grinding machine, and then place the cemented carbide processed in step 1 on the grinding part of the grinding machine, and turn on the grinding machine to clean the surface of the cemented carbide. Grinding treatment is carried out so that the convex points on the surface of the cemented carbide are polished clean.

[0059] Step 3: Fix the cemented carbide polished in step 2 with limit bolts, rinse the surface of the cemented carbide with water, the water pressure is 50 kPa, the water impact time is 55 seconds, and the distance from the nozzle to the surface of the cemented carbide is 60 mm, clean t...

Abstract

The invention discloses a hard alloy surface treatment process. The process comprises step 1, a hard alloy is put into an ultrasonic generator to be kept for 3 minutes, and wax removal treatment and oil removal treatment are conducted; and step 2, the working state of a grinding machine is detected, the grinding machine is started for working for two minutes, the grinding machine is closed after it's determined that the grinding machine works normally, then the hard alloy treated in the step 1 is placed on the grinding portion of the grinding machine, the grinding machine is started to grind the surface of the hard alloy, so that convex points on the surface of the hard alloy are ground to be removed. The hard alloy surface treatment process has the advantage of high surface treatment efficiency, in step 6, a compound liquid is firstly used for reacting with partial impurities on the surface of the hard alloy, and then playing a role in polishing on the surface of the hard alloy, so that the processing cycle of the hard alloy is greatly shortened, the percent of pass of the hard alloy is increased, the production cost of an enterprise is greatly reduced, and earnings of the enterprise are improved.

Description
