Custom Steel Alloy Laser Cutting And CNC Milled Bar Adapter

Product Introduction

This is a alloy steel bar adapter made by laser cutting first, then CNC machining. And this is a kind of guide plate using on the chainsaw.The guide plate, also known as the chain plate or saw plate, is a core component of the chainsaw transmission system. Its main function is to support and guide the saw chain to complete the cutting operation. The material is mostly 50 Mn steel or 65 Mn steel. According to the structure, it is divided into two types: combined type and integral type. The combined type is formed by welding or riveting multiple steel plates, and can be divided into laminated type and replaceable head type.

Material and Process

Our adapter used the material alloy steel 50CrV4. 50CrV4 is a high-performance alloy steel renowned for its exceptional combination of strength, toughness, and fatigue resistance. Vanadium carbides precipitate during heat treatment, reinforcing the matrix against abrasive wear. Chromium improves resistance to surface fatigue in cyclic loading.

It's moderate machinability and can be cold-formed into complex shapes before heat treatment, though high-strength applications often require hot working.

Here is the sketch of the adapter:

The process begins with laser cutting a hot-rolled alloy steel plate, followed by grinding the cut surfaces for smoothness. Next, a CNC milling operation creates a groove with a width of 1.575 inches (±0.005 inches tolerance), ensuring it is centered precisely on the plate. This sequence ensures dimensional accuracy and surface quality critical for high-precision applications.

Packing

To protect the surface, each bar adapter is individually packed in a plastic bag, then placed in a carton. The cartons are stacked on a pallet and wrapped with stretch film to prevent shifting during transport.

Ningbo Joyo Metal Product Co., Ltd is careful in every aspect from material selection to packaging, maintaining strict quality control throughout the process. We source premium materials and verify their certifications, implement in-process inspections during manufacturing to ensure precision within tight tolerances, conduct rigorous functional and durability tests on components, and secure palletization to prevent damage. This comprehensive approach guarantees that each product meets our high-quality standards before delivery.
