Sandvik Corona high speed steel tool bits complement cemented carbide in operations where cutting

speeds or edge profiles are not suitable for hard tool materials. HSS tool bits are a suitable alternative

because they are:

– extremely tough tool material; work well at low cutting speeds and in intermittent cuts.

– regrindable; a large number of cutting edges can be produced on same tool.

– easy to grind into sharp, positive edges; useful for small component manufactures

– possible to ground cutting edge profiles as required and easily adaptable to a very wide range of customer needs.

Grades

Grade C45 should always be first choice with C60 as an

alternative when high wear resistance is required.

Nominal cutting speed and feed values

The recommendations are valid for rough turning with Sandvik Corona grades and use of cutting fluid. Approximate tool life with C45/60: 2 hours (or 1 hour with approx . 20% higher speed)

For a cutting depth ≥1,5 mm the nose radius should be ≥1,0 mm. For a cutting depth <1,5 mm the nose radius should be <1,0 mm.

Sandvik Corona grades

The Sandvik Corona grades C45 and C60 give the essential properties of wear resistance, toughness and ease of grinding. Grade properties are obtai-ned by combining the steel compositions and structure with the most advanced manufacturing methods.

Grade C45. Should always be first choice. A high alloyed High Speed Steel capable of withs-tanding high temperatures at the cutting edge. Grade C60. Alternative to be used when high wear resistance or good grinding properties are decisive criteria. A high alloy powder metallurgical grade with a more even distribution of carbide particles.

C45 C60 C 1,40 2,30 Cr 4,2 4,0 Mo 3,5 7,0 W 8,5 6,5 V 3,5 6,5 Co 11,0 10,5

Cutting geometry

Machine type and workpiece material determine the cutting tool geometry with a general rule that the cutting edge should be provided with positive angles. The recommendations are nominal values which may have to be changed according to machining conditions. When using heavy feed the clearance angle (α_n) and rake angle (γ_n) should be reduced to achieve a stronger cutting edge (β_n).

Chipbreaking

When machining long chipping materials a chip-breaker (h_B) can be ground for better chipbrea-king. However, too large an hB-value may cause chip-jamming.

Grinding

The characteristics of the tool bit depends to a large extent on how the grinding and sharpening of the cutting edge is carried out. To obtain the best result, the grinding data should be selected in consultation with the grinding wheel supplier. The data given are general recommendations.
