What You Need to Know About CNC Shearing Machine

Estimated reading time: 3 minutes

CNC shearing machine is mainly used to cut a certain thickness of steel plate material, commonly used shearing machine is divided into flat shear, rolling shear and vibration shear 3 types, shearing thickness less than 10mm shearing machine is mostly mechanical transmission, greater than 10mm for hydraulic transmission.

The Adjustment of The Rear Material of The Shearing Machine

  1. The shear size of the CNC shearing machine is mainly related to the rear gear material. If you want to have a certain dimensional accuracy, you should adjust the rear material of the shearing machine. In this way, we can avoid problems, but also to ensure the normal operation and use of the equipment, in order to have a good use effect.
  2. The adjustment of the Baffle of the CNC shearing machine is realized through the CNC panel. Therefore, its automatic adjustment is mainly to see whether the settings on the CNC panel are reasonable, and whether its operation is in place. The general operation is to click on the data input and enter the retainer data. Then press Auto press and press Start again, so that the rear gear material can be automatically in place.
  3. If you use a CNC shearing machine to cut steel plates, in terms of cutting thickness, it is related to the blade clearance. If the sheet gap of 1 to 3 mm is cropped, then in terms of adjustment amount, it is 1 to 2 mm, if it is 4 to 10 mm, then the adjustment amount is 3 to 5 mm.

Adjust the scissor gap of the shearing machine according to the specified shearing plate thickness! It is not allowed to cut two different specifications at the same time! Sheets of different materials must not be sheared! Sheared sheets require a flat surface, and narrower sheets that cannot be sheared and cannot be pressed tightly are not allowed! To do the correct adjustment and use of the device.

How Many Types of Cutting Machine Blades Are There?

Blade is one of the accessories of the shearing machine.

According to The Shearing Machine Model:

Hydraulic pendulum shearing machine blade, hydraulic gate shearing machine blade, electric shearing machine blade, foot pedal shearing machine blade, CNC electro-hydraulic servo shearing machine blade, electric pendulum shearing machine blade.

According to The Combination of Blades:

Integral shearing machine blade (upper and lower blades are created as a single piece), combined split shearing machine blades.

By Material:

Low alloy tool steel shearing machine blade (such as 9CrSi), alloy tool steel shearing machine blade (such as: 6CRW2SI, ), such materials are widely used, so now many manufacturers use this material. High alloy tool steel shearing machine blade (such as: CR12MOV, CR12MO1V1, H13K, SKD-11, D2, LD, etc., customers need to choose their own blade according to their own cutting requirements, such materials to make blades, the cost is relatively large, generally used to cut difficult to cut materials or thick plates.

The blade edge is generally a sloped slant, the angle is between 6-10 °, and the lower knife edge is mostly a flat knife edge. In this way, when cutting the plate, it will not cause gaps and will not damage the blade and the blade.
