PURPOSE
For Sawing of Timber in Saw Mills and Production Shops
DESIGN FEATURES :
MACHINE BASE: Shall be all steel fabricated out of best quality steel and shall
have machined facings to support the tables, Top and Bottom spindle assemblies
and the Column and
shall be very rigid and sturdy.
COLUMN: Shall be all steel fabricated and will carry the upper wheel
assembly.
SAW PULLEYS: Will be solid Plate type of castings machined all over and
balanced. The faces shall
have a slight crown to ensure accurate Saw Tracking. Both the top and bottom
pulleys shall be mounted
on machined and tapered spindles. The top pulley is lighter than the bottom so
that over running
will not occur.
PULLEY BEARINGS: The pulley bearings shall be of heavy-duty self-aligning roller
type and shall be
enclosed in dustproof housings. Each spindle shall be supported by two such
bearings, one on each side
of the pulley, which is not over hung. The bearings on the top spindle shall be
pivoted from fulcrum pins
in the jaw piece.
SAW STAINING SYSTEM: Saw staining system is provided through powerful coil
spring and readable on a
convenient scale stain provided to the blade.
SAW TRACKING: Sensitive tilting arrangement to the top saw wheel is provided
controlled through a
hand wheel for the purpose of tracking of the saw blade.
TABLE: The table is made of close-grained cast iron accurately machined to give
a bearing surface
of 1100 mm square approx.
FENCE: Shall be Multi roller fence of robust construction and frictionless. It
shall be set by the handwheel through rack and pinion gear. A scale is provided which indicates
accurately the width of cut.
FEED ROLLERS: Both vertical and horizontal feed rollers are given through a
Hydraulic system to
provide them an infinitely variable feed of 8 to 76 meters per minute.
SAW GUIDES: Both Top and Bottom blade guides shall be provided. The guides are
of white metal
lined adjustable for wear. The Upper Saw Guide is adjustable through a motorized
mechanism and
can be set at any desired height. The Bottom Guide is close to the table bottom
and shall have a saw
dust deflector immediately below them.
SAW GUARDS:
TOP GUARD: Shall be provided to safely protect the saw on its passage round the
Top Pulley
whilst the front guard which rises and falls with top Saw Guide covers the saw
down to the guide.
BOTTOM GUARD: Covers the Bottom Pulley above the floor level and is provided
with Hing opening for saw changing.
CLEANING PAD Cleaning Pad and Brushes shall be provided on the top and
BRUSHES: bottom pulley and the saw at the back of the machine to ensure that the
saw is
continuously cleaned.assembly and 5 H.P Motor for Feed Roller Assembly.
STARTERS: Suitable starters are provided for each motor.
All electricals operate on 415 volts, 50 cycles, 3 Phase A.C. Current.
LUBRICATION: Lubrication shall be effected through grease nipples to all ball
and roller bearings, except
for the gear box which shall be sump feed, centralized lubricated.
The lubrication instruction plate shall be attached to the machine.
MASTER STOP : Master stop shall be provided within easy reach of the operator.
