The Lathe Processing Computerized Numerical Control Machine for Parts

CNC lathe is a kind of high precision, high efficiency of automatic machine tool, the use of CNC lathe can improve processing efficiency, create more value, the emergence of CNC lathe makes enterprises get rid of the backward processing technology, CNC lathe processing process is similar to ordinary lathe processing process, but because the CNC lathe is a clip, continuous automatic processing completed all cutting process, so we should pay attention to the following aspects.
  Three elements of cutting conditions: cutting speed, feed amount and cutting depth directly cause damage to the tool.With the increase of the cutting speed, the knife tip temperature rises, causing mechanical, chemical, and thermal wear.Cutting speed increased by 20% reduces tool life by 1 / 2.
 How to determine the three elements of cutting and processing

How to correctly choose these three elements is a main content of the metal cutting principle course. Metal processing WeChat extracts some key points and selects the basic principles of choosing these three elements:

(I) Cutting speed (line speed, peripark speed) V (m / minute)

To select the number of spindle revolutions per minute, you must first know how much the cutting line speed V should take.Selection of V: depends on the tool material, workpiece material, processing conditions, etc.

cutter material:

Hardcore alloy, V can be higher, generally desirable 100 meters / point, generally the purchase of blade to provide technical parameters:

Processing of what material can choose how many large line speed.High-speed steel: V can only be achieved relatively low, generally not more than 70 m / point, in most cases to take 20~30 m / point below.

Workpiece materials:

The hardness is high, V is low; cast iron, V is low, the tool material is carbide is desirable 70~80 m / min; low carbon steel, V is preferably 100 m / min, non-ferrous metal, V is preferably higher (100~200 m / min).Quenched steel, stainless steel, V should be lower.

This product is CNC lathe processing, mainly used for new energy vehicle drainage joints, the product sealing performance, surface rough requirements are relatively high.
