Speaking of handboard making, do you know what methods are used to process handboard models in Qile Ruibang?

With the gradual growth of the handboard industry, the manufacturing process is also becoming increasingly updated, including 3D printing and silicone remodeling.

But CNC machining is still the most common way to produce parts. Currently, there are several common methods for sharp binding of CNC machining handboard models:

01. Turning

Turning simply involves clamping the workpiece firmly onto a rotating plate or mandrel. When the workpiece rotates, the cutting tool is fixed against it in a fixture mounted on the moving slide.

The slider can move up and down along the length of the workpiece, as well as closer to or away from the centerline, and this simple operation is ideal for quick removal of large amounts of material.

In addition, drill bits mounted on the lathe tail seat can drill precise holes; lathes are used to form concentric shapes on the outer periphery of circular components; making grooves, ring grooves, step shoulders, internal and external threads, columns on lathes Body and axis - many circular or circular features.

02. Milling

Milling is fundamentally different from being that the workpiece remains stationary and the cutting tool rotates on the mandrel. The workpiece is usually held horizontally in the machine vise and mounted on a workbench moving in the X and Y directions.

The spindle can hold various tools and move on the X, Y and Z axes. Milling cutters are used to create squares/planes, notches, chamfers, channels, profiles, keyways and other features that rely on precise cutting angles.

As with all metalworking operations, cutting fluid is used to cool workpieces and cutting tools, to lubricate, and to flush away metal particles or chips.

03. Grinding

Grinding is important for many applications to manufacture very flat surfaces on metal parts, and the best way to make such precise surfaces is to use a grinder.

A grinder is a rotating disk covered with abrasive sand particles of a specific roughness. The workpiece is mounted on the workbench and moves laterally back and forth on the sliding table below the grinding wheel, or sometimes remains firm as the grinding wheel moves. Depending on the material being ground, different types of abrasives are used.

Thermal and mechanical stresses of the grinding process can adversely affect the workpiece, so careful control of tool speed and temperature must be done.

04.EDM

Solid EDM is used to create pits, holes and square features inside hardened tool steel, and if not impossible, it is difficult to do any other way.

It is commonly used in plastic injection and pressure casting molds and rarely used in the finished parts themselves. EDM is also used to make textured surfaces or recessed (recessed) letters and logos on molds.

05. Wire cutting

Wire cutting uses copper wire as conductors of high voltage charge. As the conductor is stably corroded during the cutting process, the new wire is supplied from the spool.

This technique needs to be passed and cannot be used for blind holes. Wire cutting is used on thick, hardened tool steel to create circular or semicircular features, which will be very difficult to manufacture with conventional cutting tools.

06. Optical grinding

Optical Grinding We only discuss processing metals, but CNC processing is also used to make special optics for glass or plastics.

Optical devices require very fine surfaces with very tight tolerances, so specialized grinding equipment is used to rotate the grinding wheel relative to the surface when rotated on multiple axes.
