Description

"Clamping device for angular positioning of semi-finished products before their subsequent processing. Precise values are obtained solely thanks to the high-quality manufacturing of the vise, as well as the ground reference plates."

Information:

✔️Clamping device for angular mounting of elements in the range of 0° - 45°.

✔️The main and most important feature of the vise is sinusoidal value setting using reference plates.

✔️Proper values are achieved thanks to correctly manufactured vise components; only their manufacturing precision and properly ground surfaces will accurately reflect textbook tolerances.

✔️The device is made from high-quality alloy steel with a working surface hardened to 58-62 HRC.

✔️The SPZSA model is distinguished from its counterparts by a standard pull screw, which extends and retracts parallel to the movable jaw.

✔️The prism-shaped movable jaw, i.e., having vertical and horizontal grooves, allows clamping of shafts.

✔️This vise is used during precise and accurate machining and measuring work on grinders, milling machines, CNC machining centers, and other machining tools.

✔️All screws used have universal hex socket heads.

✔️A strong base allows mounting the vise on another clamping device; just remember to mount it correctly on stepped jaw inserts or using parallel washers.

How to calculate and set the tilt angle:

Data:	Unknown:
c = 100mm α = 45° sin45° = 0.7071	a = ?
Solution:
sinα = a/c a = csinα a = 1000.7071 a = 70.71 [mm]

Data:

Unknown:

c = 100mm

α = 45°

sin45° = 0.7071

a = ?

Solution:

sinα = a/c

a = c*sinα

a = 100*0.7071

a = 70.71 [mm]

To achieve a tilt angle of 45°, a stack of plates with a height of 70.71 mm should be arranged.

A table of values for the sine trigonometric function may be useful.
