Carbide Inserts

Carbide inserts are usually indexable, they can be exchanged, and rotated or flipped, without disturbing tool effective diameter, tool length offset, etc. This saves time and increased efficiency in manufacturing.

Milling carbide inserts play a key role in milling processing, Suitable milling inserts could help more productivity, milling has been evolved into a method that machines a very broad range of operations. As an important part of milling, in addition to all the conventional applications, milling is a strong alternative for producing holes, threads, cavities, and surfaces that used to be turned, drilled, or tapped.

UKO milling carbide inserts range includes planer type milling inserts (TPKN/SPKN/SEKN and etc), Fast feed milling inserts(SDMT/LNMG/WNMU/LNMU/HNMG/SNMX/SNMU/ENMU/SOMT/LOGU/PNMU and etc) of heavy cutting and basic milling inserts of shoulder milling and face milling(APMT/APKT AND R series. for the application area of steel, stainless steel, hardened steel, nickel-based alloys, and aluminum.


Shoulder milling generates two faces simultaneously, which requires peripheral milling in combination with face milling. Achieving a true, ninety degree shoulder is one of the most important requirements. Shoulder milling can be performed by traditional square shoulder cutters, and also by using end milling cutters, long edge cutters and side and face milling cutters. Due to these numerous options, it is essential to consider the operational requirements carefully in order to make an optimal choice.

Face milling with a very high feed per tooth is possible when using cutters that have small entering angles or when using round insert cutters, due to their chip thinning effect. Specific cutter concepts are optimized for extreme high feed milling at small axial depths of cut. A small entering angle is the precondition required for applying a light and fast, high feed.

UKO supply basic milling inserts of shoulder millling and face milling(APMT/APKT AND R series to you whether you are milling shoulders, trying to avoid vibration, or some special requirements and precise contours.

What is carbide end mill?2021-09-28T06:56:36+00:00

Carbide endmill is an industrial rotating cutting tool that can be used for milling operations, which is made from tungsten carbide (WC) and cobalt (Co) materials. They are also commonly referred to as a “carbide milling bit”. Center cutting end mill can be used for plunging operations (axial milling), and can also be used in side milling operations (radial milling). Non-center cutting bits may only be used in side milling applications.
The most common material used for end mills is tungsten carbide, but HSS (high speed steel) and Cobalt (high speed steel with cobalt as an alloy) are also available.

What is aluminum high-speed steel (HSS-Al)?2021-09-28T06:55:28+00:00

Aluminum-containing high-speed steel (HSS-Al) is smelted by a method of carbon (Al) elements based on molybdenum high-speed steel and is designed to increase thermal hardness and wear resistance.

The performance of the aluminum-containing high-speed steel is similar to the cobalt-containing ultra-hard high-speed steel, the hardness of the heat treatment is HRC67 ~ 69, the anti-bending strength is 290 kg / square millimeters, the impact value is 2.3~3kg 1m/cm² The high-temperature hardness at 600°C is HRC54~55.

Aluminum-containing high-speed steel (HSS-Al) forging performance and excellent cutting performance, but grinding performance is lower than normal high-speed steel when grinding with white jade wheels, and superior to high-speed steel and high vanadium high-speed steel and high vanadium Cobalt high-speed steel.

The durability of the HSS-Al tool is similar to the cobalt-containing ultra-hard high-speed steel, 1 to 2 times higher than the ordinary high-speed steel, up to 3 to 4 times.

What are CNC milling tools?2021-09-28T06:30:38+00:00

CNC milling tools is a rotary cutter with one or more cutter teeth, which is used for milling by CNC machine. During operation, each cutter tooth cuts off the metal allowance of the workpiece intermittently in turn.

How to classify CNC milling cutters?

A. According to the materials used to manufacture milling cutters, they can be divided into:

  • High-speed steel cutting tools.
  • Cemented carbide cutting tools.
  • Diamond cutting tools.
  • Other material cutting tools, such as cubic boron nitride cutting tools, ceramic cutting tools, etc.

B. According to the different structures of milling cutter, it can be divided into:

  • Integral type: the tool and handle are made into one.
  • Inlay type: it can be divided into welding type and machine clamp type.
  • Vibration damping type when the ratio of the working arm length and diameter of the tool is large, this kind of tool is often used in order to reduce the vibration of the tool and improve the machining accuracy.
  • Internal cooling type: cutting fluid is sprayed to the cutting edge of the tool through the nozzle hole inside the tool body.
  • Special types: such as compound tools, reversible thread tapping tools, etc.

C. According to the different structures of milling cutter, it can be divided into:

  • Face milling cutter (also known as end milling cutter): there are cutting edges on the circumferential surface and end face of the face milling cutter, and the end cutting edge is the auxiliary cutting edge. The face milling cutter is mostly made into sleeve gear insert structure and indexable structure of blade clamp. The cutter teeth are made of high-speed steel or cemented carbide, and the cutter body is 40Cr. Drilling tools, including drill bits, reamers, taps, etc;
  • Die milling cutter: die milling cutter is developed from end milling cutter. It can be divided into conical end milling cutter, cylindrical ball end milling cutter and conical ball-end milling cutter. Its handle has straight handle, flattened straight handle and Morse taper handle. Its structural feature is that the ball head or end face is full of cutting edges, and the circumferential edge is connected with the ball head edge in an arc, which can feed radially and axially. The working part of the milling cutter is made of high-speed steel or cemented carbide. Aluminum spot welder
  • Keyway milling cutter: used for milling keyway.
  • Forming milling cutter: the cutting edge is consistent with the shape of the surface to be machined.
What is CNC lathe machine?2021-09-28T06:27:43+00:00

CNC lathe machine is an automatic lathe machine equipped with a program control system. The control system can logically process the program with control code or other symbolic instructions and decode it, so as to make the machine tool operation and process parts.

Compared with an ordinary lathe machine, CNC lathe machine have the following characteristics:

  • High processing precision and stable processing quality;
  • It can carry out multi coordinate linkage and process parts with complex shapes;
  • When processing parts are changed, generally only the NC program needs to be changed, which can save production preparation time;
  • The machine tool itself has high precision and rigidity, can select favorable processing amount and high productivity (generally 3 ~ 5 times that of ordinary machine tools);
  • The machine tool has a high degree of automation, which can reduce the labor intensity;
  • Higher quality requirements for operators and higher technical requirements for maintenance personnel.

CNC lathe machines are generally composed of the following parts:

  • Host, which is the subject of CNC machine tools, including machine body, column, spindle, feed mechanism and other mechanical parts. It is a mechanical part used to complete various cutting processes.
  • NC device is the core of NC machine tool, including hardware (printed circuit board, CRT display, key box, paper tape reader, etc.) and corresponding software. It is used to input digital part program, complete input information storage, data transformation, interpolation operation and realize various control functions.
  • The driving device, which is the driving part of the actuator of NC machine tool, including spindle driving unit, feed unit, spindle motor and feeds motor. He realizes spindle and feeds drive through electrical or electro-hydraulic servo system under the control of NC device. When several feeds are linked, the machining of positioning, straight line, plane curve and space curve can be completed.
  • Auxiliary devices, some necessary supporting parts of index control machine tool, to ensure the operation of NC lathe machine, such as cooling, chip removal, lubrication, lighting, monitoring, etc. It includes hydraulic and pneumatic devices, chip removal devices, exchange worktables, CNC turntables and CNC indexing heads, as well as CNC inserts and monitoring and detection devices.
