XCP Series carbide radius end mill high hardness steel processing / multi-blade / 50 ° twist / regular type
Caution
Product Description
[Features]
- Radius included for chipping-less processing of high-hardness steel.
- An end mill with a radius added to the high helix end mill for machining high-hardness steel.
・Since the tool rigidity is high, it is possible to minimize the tool tilt during side milling.
・High hardness steel machining up to 65HRC is possible.
・The radius cutting edge also helps prevent chipping.
《Price》・Regular unit price from 7,520
yen/piece (1 to 4 pieces)・More profitable with bulk orders from 6,910 yen/ piece
(10 to 29 pieces) can be specified. ・No need to create drawings. Orders can be placed only by specifying the dimensions in the model number. ・"Only the required quantity at the required time" is available from 1 unit. ・Delivered on the 3rd day.
Alteration end mill designation method
Alteration (neck relief only) SN- / SNR-
● Additional machining model number for "Additional neck relief machining only"
SN- : Standard neck relief processing / SNR- : Neck relief cutting edge with R (0.4R) processing
● Ships in as little as 3 days
― Procedure for specifying alterations ― (1) From the Misumi VONA top page, select [Cutting Tools] → [ (2) Select "Misumi" in [Filter by manufacturer], (3) Specify [specifications/dimensions] such as "blade diameter/number of teeth"
(5) SN- specifies the "neck length", SNR- specifies the "flute length / neck length", and determines the alteration (6) Check the price and shipping date at [Confirm price] and place an order.

Point 2 when cutting high-hardness steel
[Question]
How to successfully cut hardened steel?
End mill cutting of high-hardness steel shortens the tool life, so frequent tool changes and dimensional corrections are often required. Please let me know if you have any solution.
[Answer]
Selection of suitable tools and tooling for hard materials
When selecting a tool, it is effective to select a shape with a strong cutting edge and a shape with a large number of teeth and high rigidity. (Refer to page 12 for the characteristics of high-hardness steel and processing points.) For
coated cemented carbide tools, it is important to select a coating with excellent high-temperature characteristics and heat resistance.
MISUMI TS Coat has high hardness and high temperature resistance to oxidation, so it can be expected to increase the durability of tools.
For tooling, a shrink-fit holder with high gripping force is effective. Until now, shrink-fit holders have often been used mainly for finishing machining due to their good run-out accuracy. Stable machining is possible in steel machining.
Adjust by cutting amount instead of feed
If the tool is not wearing normally but is wearing rapidly due to chipping, it is necessary to review the tool selection and cutting conditions.
A negative rake angle is effective in increasing the strength of the cutting edge. (Refer to page 72 for the rake angle of the negative shape). Ultra-fine particles with high hardness and fine particles are suitable for ultra-hard materials. In addition, the number of CBN tools with high hardness is expected to increase in the future.
When reviewing the cutting conditions, it is recommended to first reduce the depth of cut rather than drastically lowering the feed rate. In order to maintain the durability of the tool and improve the finished surface, it is important that the cutting speed is high rather than low.
Recommended cutting conditions
● Use a machine and chuck with high rigidity and high accuracy.●Select a cutting oil suitable for the work material.
●Avoid using highly flammable cutting oil under high-speed conditions, and use air blow or MQL.
●If the machine you are using does not increase the rotational speed, reduce the feed rate and rotational speed by the same ratio.
●Keep run-out of the cutting edge within 0.01 mm when installing an end mill.
●Use down cut for side cutting.
●If chattering occurs during side milling, lower the cutting conditions.
●For XCP-MSXL and XCP-MSX4LB, use the feed speed and rotation speed at 70% below.
