Machining of mechanical parts refers to the processing of parts through machining. Machining mainly refers to the process of cutting a workpiece using machine tools. Parts manufactured through machining are widely used in various industrial machines, including automobiles and aircraft. Machining is classified based on the characteristics of the motion and the tools used. 【Examples of typical machining processes】 ■ Lathe machining ■ Milling ■ Cylindrical grinding ■ Surface grinding *For more details, please download the PDF or feel free to contact us.

There are issues in the procurement aspect of machining mechanical parts. Estimates for machining mechanical parts can vary significantly between suppliers, even for the same drawings. It can be difficult to understand the basis of the estimates, making it hard to determine whether the quoted amounts are truly accurate. Especially from the perspective of someone placing an order for machining mechanical parts, it is a major concern whether the estimates provided are genuinely correct. [Issues in the Procurement of Machining Mechanical Parts] - Estimates for machining mechanical parts can vary significantly between suppliers, even for the same drawings. - The basis for the estimates is often unclear, making it difficult to judge whether the quoted amounts are truly accurate. - Even when ordering based on the same drawings, the quality of the products can differ depending on the supplier. *For more details, please download the PDF or feel free to contact us.*

This document explains the concept of estimating machining costs for mechanical parts. Estimated amount = material costs + machining costs + heat treatment and surface treatment costs. The basic idea is that machining costs = machining charge × machining hours. The elements that make up the estimated amount are "material costs," "machining costs," and "heat treatment and surface treatment costs." Among these, "machining costs" carry the highest weight. [Basic Concept of Estimating Machining Costs for Mechanical Parts] ■ Estimated amount = material costs + machining costs + heat treatment and surface treatment costs ■ Machining costs = machining charge × machining hours *For more details, please download the PDF or feel free to contact us.

At first glance, it seems that the lower the "processing charge," the lower the processing costs will be. However, in reality, the "processing man-hours" have a greater impact on the overall processing costs than the "processing charge." The actual processing charge is determined by the initial cost of the equipment owned, the residual value after depreciation, the running costs to operate the equipment, and the labor and management costs of the workers. 【Factors determining the actual processing charge】 ■ Initial cost of the equipment owned and residual value after depreciation ■ Running costs to operate the equipment ■ Labor and management costs of the workers *For more details, please download the PDF or feel free to contact us.

If a parts processing manufacturer has high expertise in a certain processing method, they can provide estimates with minimal processing man-hours. However, even for the same processing, parts manufacturers without experience tend to have a higher number of processing man-hours due to precautionary measures. Depending on the content of the processing, there may be a need to acquire new tools and establish new conditions, create new jigs, or modify existing tools to create special tools. These factors also affect the processing man-hours. [Points Affecting Processing Man-Hours Common Items (Partial)] ■ Whether new tools or jigs are needed ■ Number of tools used ■ Price of tools used ■ Setup time before processing ■ Processing time ■ Required precision *For more details, please download the PDF or feel free to contact us.
