The goal is to produce an excellent quality cut and efficiency during multiple identical cuts.
The user must consider the quality of material in respect to hardness, shape, and thickness
to determine the proper descent rate, blade/disk speed, and saw blade/disk type. A
harmonious combination of materi al, rate, speed, and type are required to achieve a quality
cut. So great care and thought should be made into planning for a single operational cycle
then efficiency can be achieved for multiple identical operations. With good knowledge of
machine specification and careful consideration and common sense, the user can attain the
goal and overcome any problem that may appear from time to time.
11.1 Disk Structure
The most commonly used disks are made of extra high speed steel (HHS/Mo5+Co5) with a
treated tooth , which differentiates them from the former on account of the high value of
structural resistance, greater resistance to seizing, absence of stress in the mass and a
better holding of lubricating coolant during work.
11.2 Choosing the Saw Blade
Choose a tooth pitch that is suitable for the workpiece. Please refer to Tooth pitch .
Thin walled or variable section work pieces such as profiles, pipes, and plates require
closed toothing, so that at least 3~6 teeth are in contact with the material while cutting.
La rge solid or transverse sections require widely spaced toothing to allow for greater
volume of the shavings and better tooth penetration.
Soft materials or plastics such as light alloys, mild bronze, Teflon, wood, etc., require
widely spaced toothing to av oid clogging.
Page 15
Instruction Manual for CS-315D (S828)
03/12/2014

11.3 Type of Disks
The disks differ essentially in their constructive characteristics, such as:
Tooth shape
Tooth cutting angle
Tooth shape
The profile of the toothing depends on the size, shape and thickness of the section to be cut,
either straight or at a n angle.
It may also vary according to the pitch, but not so distinctly as to make this an element for
classification.
Fine toothing is to be chosen for cutting small sections with a profiled shape and tubular
sections with thin walls (2 - 5mm depending on t he material).
Large toothing is suitable for cutting medium and large solid sections or fairly thick profiled or
tubular sections (over 5mm).
A toothing : AW toothing :
Normal fine toothing Fine toothing with alternate side rake

B toothing : BW toothing :
Normal large toothing with or without Large toothing with alternating side rake
shaving breaking inclusion.
C(HZ) toothing :
Large foothing with roughing tooth with rake on both sides, alternating with a finshing tooth
without rake. The toughing tooth is 0.15 - .30 mm higher.
Added toothing:
Disk made in the w ay are used for cutting non - ferrous metals, such as light alloys, and
plastics, and above all in woodworking. The teeth are hard metal (HM) plates brazed onto
the body of the disk; there are various types and shapes and, considering the vastness of
the fi eld, the topic is not developed further here.
Tooth cutting angle
Each tooth has two cutting angles :
-
: front rake angle
-
: rear rake angle

R ake s vary in accordance to material to be cut.
11.4 Choosing the Tooth Pitch
Se lect tooth pitch based on, harness of the materials, dimensions of the section, and,
thickness of the wall
11.5 Cutting and Advance Speed
The cutting speed (m/min) and the advance speed (cm2/min= area traveled by the disk teeth
when removing shavings) are limited by the development of heat close to the tips of the
teeth.
The cutting speed is subordinate to the resistance of the material (R= N/mm2), to its
hardness (HRC) and to the dimensions of the widest section.

To high an advance speed (=disk descent) tends to cause the disk to deviate from the ideal
cutting path, producing non - rectilinear cuts on both the vertical and the horizontal plane.
11.6 Running in the Disk
When cutting for the first time, it is good practice to run in the tool making a series of cuts at
a low advance speed (=30~35 cm2/min on material of average dimensions with respect to
the cutting capacity and solid section of normal steel with R= 410 - 510 N/mm2), generously
spraying the cutting area with lubricating coolant.
