Deburring 

A burr is a small piece of excess material that appears on the edges or around the holes of a workpiece during metal processing. They typically present as sharp protrusions or fragments. Burrs are commonly formed during processes like stamping, cutting, milling, drilling, and tapping, and are especially prominent under high-speed or high-pressure conditions.

• Reduces Product Aesthetic Quality:
  Burrs create an uneven surface, affecting both the visual and tactile feel of a product.
• Causes Assembly Difficulties:
  Burrs can hinder the precise fit between parts, reducing assembly efficiency and accuracy.
• Compromises User Safety:
  Sharp burrs can easily cause cuts, impacting product safety for the end-user.
• Increases Wear and Failure Rates:
  Burrs can detach during operation and enter the mechanism, causing internal wear or damage.

This is a traditional and flexible method that uses files, sandpaper, or grinding wheels for manual finishing. Its advantage is adaptability, making it suitable for small batches of complex-shaped parts. Its main drawback is that it is time-consuming and the quality is highly dependent on the operator's skill.

This method uses tumblers, grinding machines, or brush-equipped systems for high-volume processing. It is fast and highly repeatable, making it suitable for standardized, mass-produced products.

Parts, along with abrasive media, water, and additives, are placed in a vibratory finishing machine. The vibration generates friction to remove burrs. This method is especially suitable for small parts or high-volume production lines.

This method uses high-speed blasting (a mixture of sand, water, and air) or dry ice to remove burrs. It can treat intricate areas and internal structures, making it suitable for electronic and medical components.

This is a non-contact method that uses an electrolyte and an electric current to dissolve burrs. It is ideal for precision parts and is commonly used in the automotive and aerospace industries.

This method uses high heat or a laser to instantly melt burrs. It is primarily used for specific metal materials or high-value products requiring precision processing.

HIROKI is equipped with vibratory finishing machines, automated tumblers, and brush deburring equipment. This allows us to select the most suitable method based on the product’s material, shape, and quantity.

For different industry needs, we design a process flow that pairs our initial stamping with automated post-deburring. This reduces processing risks and improves yield and consistency.

Through automated control and data monitoring systems, we can check deburring results in real-time, ensuring consistent and stable quality for every batch.

Burrs on precision terminals, connectors, or sensor components can affect electrical contact, potentially leading to short circuits or poor connections. HIROKI uses a micro-vibratory, dust-free deburring solution for these products to ensure electrical stability

Components like brake systems, structural brackets, and adapters must have safe, burr-free edges to ensure proper installation and operational safety. HIROKI guarantees meticulous detail by using a combination of tumbling and manual inspection.

Large quantities of hardware tool components, such as drill bits and wrench heads, are often rapidly mass-produced via stamping. HIROKI designs a process that integrates continuous dies with an automated deburring station to save time and cost.

Our all-in-one process, from stamping to deburring, eliminates transportation and outsourcing delays, ensuring fast delivery with minimal risk.

We handle a wide range of metals, including SPCC, SUS304, aluminum alloys, phosphor bronze, and silicon steel sheets, providing the most suitable deburring solution for each.

Our fully automated process, combined with quality tracking, maintains a yield rate of over 98%, ensuring a stable supply for various industrial orders.

Based on a client's product function and assembly requirements, we provide professional deburring recommendations for micro-areas like holes, edges, and grooves, along with customized die and fixture design.

Every product is manually touched and visually inspected by an operator to ensure there are no sharp edges, cracks, or residual protrusions.

We use a CCD optical system for full inspection to detect burr residue at the micron level.

We use projectors and CMMs to ensure that the dimensions after deburring remain within tolerance.
