Classification of Nakayama’s CUTTING RULES

CA(No-High-frequency hardening)
Standard blade; uniform hardness
NCA(Senter Bevel)
Blade edge is processed by high-frequency hardening to obtain durability.
NCD (Double Long Bevel)
Suitable for punching thick material
NCE (Triple Long Bevel)
Suitable for punching thick material
NCC (Side Bevel)
Best for punching to obtain straight cross-section surface
NCF (Side Double Long Bevel)
One side of the bevel is straight; the other side is double; superior durability
MIR Rule
Mirror finish on the blade edge. Ultimate sharpness and low cut resistance create smooth cross-section and prevent paper dust.
PERFORATING RULES (Center Bevel)
Best for tearing or folding from perforation
NC (LABEL RULES)
With height of 6H to12H
NCD60 Series
Double Long Bevel with bevel angle of 60 degrees, preventing paper dust
MAD60 Series
Having a back taper on the back of NCD60
Fluoro Resin Coating RULES
Non-adhesive blade with fluoro resin coating
Silky Coating RULES
Non-adhesive blade with silicone coating
PET
Blade edge is hardened at HS80 degrees. Especially for cutting resin.
NC EDGE WAVE RULES
Blade edge is wave shape. Used for cutting cardboards. The cut cardboards can be carried safely (the Product Liability Law).
FORM PERFORATING RULES
16H in height. For lateral perforating.
PERFORATING CREASING RULES
0.45×23.0/23.4. For lateral perforating
CREASING RULES (IRON)
Not hardened
SPECIAL CREASING RULES(STEEL)
Hardened
SPECIAL CREASING RULES(STEEL)(Dull Point)
Hardened edge is rounded at a sharp angle.
CUT CREASE RULES
Cut and crease are alternately arranged; best for acute-angled folding
Hi-MIR
The edge of PET (30H or more) is mirror-finished.

CUTTING RULESとして、無くてはならない存在。それが、ナカヤマのNCシリーズ。NAKAYAMA NC Series

NC Series adopt special steel with superior durability, bending workability and stability in the same bending work. Blade edges that are sharpened with a grinding wheel made of fine abrasive grains have unparalleled sharpness. These edges(normally 0.3 mm from the blade tip), processed by high-frequency hardening to achieve high hardness of HS70 - 80 (HV550 - 680/HRC52.3 - 59.2), are less-wearing and maintain sharpness, thus ensuring a high volume of punching and creating a large quantity of punched products with smooth surfaces.

STANDARDS OF NAKAYAMA’S CUTTING RULES

STANDARD BEVELS

STANDARD BEVELS

* The above are standard bevels (Thickness of 0.7 mm).
* Bevels with different shapes and edge angles other than above are also available.

STEEL TYPE

Application Steel type
Bendable S50C
Durable (Unbendable) SK85
Resistant to corrosion SUS

The specially-hardened material forms a surface-softened layer and is highly bendable.

THICKNESS

厚さ公差

We only use steel sheets manufactured by our reliable contractor, which meet our own thickness tolerance standard.
The thickness difference between the points T1 and T2 is less than 0.005 mm.

HEIGHT

プリントアウトした加工情報(高さ情報)

Bevels of the CUTTING RULES are sharpened with a special grinding wheel made of fine abrasive grains. Height and edge angles are measured by the grinding machine in real time, controlling them in micrometer. Based on the processing information printed by lot, we only ship the products within the height tolerance range.

HARDNESS AND WIDTH OF SURFACE-HARDENED LAYER

Body hardness:
HS (Shore hardness)
40/45/50/55/60/65/70/72
Edge hardness:
HS (Shore hardness)
65/70/72/75/80
Width of surface-hardened layer:
Width of surface-hardened layer: 0.3 mm (from the blade edge) for the regular product; products with width of 0.2 - 0.5 mm are also available according to your need.
