Haas horizontal mill is a powerful CNC milling machine widely used in industries, especially in industries requiring high volume production. It features high-speed spindles, robust cast-iron construction, and automatic tool changers to reduce cycle times.

How to proficiently master the determination of cutting parameters during turning machining

When programming, programmers must determine the cutting amount for each process and write instructions into the program. Cutting parameters include spindle speed, back cutting amount, and feed rate. Different cutting parameters need to be selected for different processing methods.Haas Horizontal Mill

1. Determination of the back cutting amount ap

The back cutting amount ap is determined based on the stiffness of the machine tool, workpiece, and cutting tool. Under the condition of allowable stiffness, the back cutting amount should be made equal to the machining allowance of the workpiece as much as possible, which can reduce the number of feed times and improve productivity. When the precision requirements of the workpiece are high, it should be considered to leave a suitable margin for precision turning. The margin left for precision turning is generally smaller than that left for ordinary turning, usually ranging from 0.2 to 0.5mm.Haas Horizontal Mill

2. Determination of spindle speed

(1) The spindle speed n during turning should be selected based on the allowable cutting speed u and workpiece diameter d, according to the formula= Calculate dn/1000. Cutting speed u: Unit: m/min, determined by the service life of the tool. When calculating, refer to Table 2-3 or the cutting parameter manual for selection. For a lathe with step variable speed, the speed close to the calculated speed n must be selected according to the lathe manual.Haas Horizontal Mill

The principle for selecting cutting parameters is to ensure the machining accuracy and surface roughness of the workpiece, fully utilize the cutting performance of the tool, ensure a reasonable tool service life, and fully utilize the machine tool performance of Dongguan CNC Precision Machining Factory to maximize productivity and reduce costs.Haas Horizontal Mill
