In the rapid development of the auto parts industry, cutting tools directly affect their processing efficiency and product
quality, so which aspects can improve processing efficiency and increase product production speed?
(1) Using combination tools
When machining workpieces, combined tools (double-knife simultaneous machining) are used to avoid downtime due
to tool change, thus saving machining costs. For example, Halnn introduces BN-S300 and BNK30 CBN grade inserts,
which can simultaneously process the outer circle, end face and inner hole of brake disc, guarantee good cutting
performance under high speed cutting, and obtain high surface finish.
(2) Using a tool with a high metal removal rate
Choosing the tool with high metal removal rate as much as possible can not only save the number of passes, reduce
processing time, save processing cost, but also shorten the delivery cycle. Halnn BN-S300 CBN grade inserts, using
nano-scale bonding agent and high precision CBN particles are preferably matched to meet the stable turning of brake discs,
brake drums, pulleys, flywheels and other components.
(3) Adopt higher cutting speed
The auto parts industry is increasingly using CBN tools to machine gray cast iron and steel parts, using PCD tools to
machine aluminum parts. PCD tools can drive high speed gray cast iron parts at cutting speeds of 500-2000 m/min, although
the price of such tools is relatively high, the overall production cost is greatly reduced because the cutting speed can be
greatly increased and the tool life is extended.
Automotive parts are usually produced in large quantities, so CBN tools and PCD tools are highly economical and dry-cut for
clean production, making them popular in the automotive parts industry.
(4) Shorten the tool change time
Whenever possible, a tool that does not require removal from the machine when replacing the tool, or a tool that is designed
to greatly speed the blade replacement speed. This type of tool eliminates or minimizes downtime and saves on processing costs.
Halnn has two structures for the automotive parts industry. One is a brazed CBN tool with a hole in the middle, and the other is a
solid CBN tool. The blades of both structures do not need to be unloaded. Simply replace the blade, reducing downtime and saving
on machining costs.
In order to improve the production efficiency of auto parts, we can start from the above aspects and select suitable tools, which
not only greatly improve production efficiency, but also save processing costs, shorten lead times and improve competitiveness.
