Tension Testing Device SP 1600 S, SP 800 S
Tension Testing Device with Axial and Radial Runout Testing Device
SP 1600 S SP 800 S
These testing devices are suitable for the testing of all types of circular saw blades wherever tension problems, or axial and radial runout can occur. Suitable for the manufacture of new blades or for sharpening and repair services.
We offer 5 different device sizes:
SP 800 S testing range from 80 – 800 mm dia. test jounal 5/8″ or 16 mm dia.
SP 1000 S testing range from 120 – 1000 mm dia. test jounal 3/4″ or 20 mm dia.
SP 1250 S testing range from 150 – 1250 mm Ø dia. test jounal 1″ or 25 – 30 or 32 mm dia.
SP 1600 S testing range from 400 – 1600 mm Ø dia. test jounal 11/2″ or 40 mm dia.
SP 2000 S testing range from 400 – 2000 mm Ø dia. test jounal 2″ or 50 mm dia.
Precise testing of axial runout is only possible if the correct flange diameter is used.
The following flange diameter sizes are available:
50 mm , 80 mm , 100 mm , 110 mm , 120 mm , 130 mm , 150 mm , 160 mm , 200 mm , 250 mm , 300 mm , 360 mm , 400 mm .
. Special sizes are available on request.
Should the correct flange size not be known, it is advisable to enquire with the user of the machine in which the saw blade is used.
Checking tension:
A simple is method is used to check tension. For example: The saw straightener attempts to press the saw blade manually. The amount of force to be exerted and the extent to which it is possible to press the saw hollow are judged according to the feel of the straightener. Feel is a subjective quantity. Instead of using our hands, we take 2 pneumatic cylinders which press the saw blade hollow with the aid of a pressure regulating valve which is able to measure the exertion of force. At the same time, a dial gauge indicates the value offset by 90°. The amount of tension a saw blade should have is impossible to stipulate due to the large number of opinions and different application involved.The values ascertained for a saw blade which has proven successful in operation should be recorded in the form of a table:
