Attentions on Safety

2. Cautions regarding mounting(1) Before use, check the outside appearance of the tool for scratches, cracks, etc. and that it is firmly mounted in the collet chuck, etc.(2) If abnormal chattering, etc. occurs during use, stop the machine immediately and remove the cause of the chattering.

4. Cautions regarding regrinding(1) If regrinding is not performed at the proper time, there is a risk of the tool breaking. Replace the tool with one in good condition, or perform regrinding.(2) Grinding dust will be created when regrinding a tool. When regrinding, be sure to attach a safety cover over the work area and wear safety clothes such as safety

goggles, etc.(3) This product contains the specified chemical substance cobalt and its inorganic compounds. When performing regrinding or similar processing, be sure to handle the

processing in accordance with thelocal laws and regulations regarding prevention of hazards due to specified chemical substances.

1. Cautions regarding handling(1) When removing the tool from its case (packaging), be careful that the tool does not pop out or is dropped. Be particularly careful regarding contact with the tool flutes. (2) When handling tools with sharp cutting flutes, be careful not to touch the cutting flutes directly with your bare hands.

3. Cautions during use(1) Before use, confirm the dimensions and direction of rotation of the tool and milling work material.(2) The numerical values in the standard cutting conditions table should be used as criteria when starting new work. The cutting conditions should be adjusted as

appropriate when the cutting depth is large, the rigidity of the machine being used is low, or according to the conditions of the work material.(3) Cutting tools are made of a hard material. During use, they may break and fly off. In addition, cutting chips may also fly off. Since there is a danger of injury to

workers, fire, or eye damage from such flying pieces, a safety cover should be attached when work is performed and safety equipment such as safety goggles should be worn to create a safe environment for work.

(4) There is a risk of fire or inflammation due to sparks, heat due to breakage, and cutting chips. Do not use where there is a risk of fire or explosion. Please caution of fire while using oil base coolant, fire prevention is necessary.

(5) Do not use the tool for any purpose other than that for which it is intended.

The EHX series is a revolutionary end mill system that enables efficiency, high accuracy and rigidity by combining the advantages of both solid carbide and indexable end mills.Security and rigidity close to that of a solid type end mill because the clamping faces are all carbide.Excellent for reduced inventory over a variety of applications due to the exchangeable head.

The double face contact of the carbide head and carbide holder gives an increase in rigidity of 30%.

How to Install the Head

Run-out accuracy and head exchange accuracy

EHX How to Select EHX Holders

1

2

Using a clean cloth, wipe away oil and dust fromthe taper and end surfaces of the head and holder.

Be careful to avoid the possibility of cutting hands when fastening with bare hands directly near the blade tip. Securely fasten the head and holder end surfaces using the enclosed spanner to close off any remaining gap.

3 Refer to the table at right regarding angles forrecommended torque when necessary. For stricter usage, refer to the table right for torque wrench fastening.

・When using straight holder + standard head, interference will occur in cases where the depth of cut is larger than the length of cut of the head.

・Under cut type with relieved neck is suitable for vertical wall machining.

・The large diameter of the pencil neck holder provides stability in long overhang applications.

Using a clean cloth, wipe away oil and dust fromthe taper and end surfaces of the head and holder.

Be careful to avoid the possibility of cutting hands when fastening with bare hands directly near the blade tip. Securely fasten the head and holder end surfaces using the enclosed spanner to close off any remaining gap.

3 Refer to the table at right regarding angles forrecommended torque when necessary. For stricter usage, refer to the table right for torque wrench fastening.

・When using straight holder + standard head, interference will occur in cases where the depth of cut is larger than the length of cut of the head.

・Under cut type with relieved neck is suitable for vertical wall machining.

・The large diameter of the pencil neck holder provides stability in long overhang applications.

Work material

① Use the appropriate coolant for the work material and machining shape.② Use a highly rigid and accurate machine as possible.③ These Recommended Cutting Conditions indicate only the rule of a thumb for the cutting conditions. In actual machining, the condition should be adjusted according to the machining shape, purpose and the machine type.④ If the rpm available is lower than that recommended please reduce the feed rate to the same ratio.

Attentions on Safety

2. Cautions regarding mounting(1) Before use, check the outside appearance of the tool for scratches, cracks, etc. and that it is firmly mounted in the collet chuck, etc.(2) If abnormal chattering, etc. occurs during use, stop the machine immediately and remove the cause of the chattering.

4. Cautions regarding regrinding(1) If regrinding is not performed at the proper time, there is a risk of the tool breaking. Replace the tool with one in good condition, or perform regrinding.(2) Grinding dust will be created when regrinding a tool. When regrinding, be sure to attach a safety cover over the work area and wear safety clothes such as safety

goggles, etc.(3) This product contains the specified chemical substance cobalt and its inorganic compounds. When performing regrinding or similar processing, be sure to handle the

processing in accordance with thelocal laws and regulations regarding prevention of hazards due to specified chemical substances.

1. Cautions regarding handling(1) When removing the tool from its case (packaging), be careful that the tool does not pop out or is dropped. Be particularly careful regarding contact with the tool flutes. (2) When handling tools with sharp cutting flutes, be careful not to touch the cutting flutes directly with your bare hands.

3. Cautions during use(1) Before use, confirm the dimensions and direction of rotation of the tool and milling work material.(2) The numerical values in the standard cutting conditions table should be used as criteria when starting new work. The cutting conditions should be adjusted as

appropriate when the cutting depth is large, the rigidity of the machine being used is low, or according to the conditions of the work material.(3) Cutting tools are made of a hard material. During use, they may break and fly off. In addition, cutting chips may also fly off. Since there is a danger of injury to

workers, fire, or eye damage from such flying pieces, a safety cover should be attached when work is performed and safety equipment such as safety goggles should be worn to create a safe environment for work.

(4) There is a risk of fire or inflammation due to sparks, heat due to breakage, and cutting chips. Do not use where there is a risk of fire or explosion. Please caution of fire while using oil base coolant, fire prevention is necessary.

(5) Do not use the tool for any purpose other than that for which it is intended.
