Model D350 SA Technical Specifications
Gear Box
Constructed of high-grade cast iron, precision machined. This is a direct drive motor to gear box, coupled via 2 piece coupler with a high resistance rubber pad between. This design generates optimum performance in a noise-free atmosphere. Maintenance free.
Safety Guards
Designed with safety and rigidity in mind there 2 piece inner and outer guards work as a shields to fully cover the sawblade and protect operator in any position of the head from accidental contact with sawblade.
Coolant System
Seal-less electric coolant pump is mounted on top of of removable large capacity coolant tank. Tank located in base of machine. Coupled with detachable hose to the coolant nozzle, based on top of inner guard. Flow is easily controlled by valve. Controlled and protected with switch, which gives user the convenience of turning the coolant system on-off and thermally protecting it at the same time.
Electric Motors
Model D350 – 3 HP Motor
Model D315 – 1.5 HP Motor
All Doringer machines are driven by AC constant torque motors. Every motor is protected with overload protection switch, set for your particular machine.
Due to a variety of materials customers are cutting, we offer at no extra charge the following motors:
Model Type “A”: with a 2 speed switch,
Mounted on motor and set for:
On speed #1 – 1700 RPM for mild steel
On speed #2 – 3400 RPM for non-ferrous
Model Type “B”: with a 2 speed switch,
Mounted on motor and set for:
On speed #1 – 850 RPM for alloys and stainless
On speed #2 – 1700 RPM for mild steel
The speeds shown above are motor speeds only, and are further reduced in ratio 1:31 which is the actual sawblade speed.
| Motor RPM | Sawblade RPM |
|---|---|
| 850 - 1700 | 27 - 54 |
| 1700 - 3400 | 54 - 108 |
Please specify voltage: 220v. 3ph or 440v. 3ph.
Turn Table
Constructed of cast iron class 40, used in the industry for precision parts and high resistance to wear, machined to tolerances not to exceed ±0.001″. The flat base with scale conveniently marked on top also incorporates the turn table, which turns left and right for mitering purposes, without turning the workpiece.
Clamping Unit
Two Separate air cylinders are used to clamp material on place. Each individually adjustable for depth and air pressure. Total clamping power 8,000 pounds, if used with 100psi. Each cylinder could be easily moved left or right, allowing sawblade to finish the cut. Total movement forward of cylinder, when actuated is 0.250″, which insures safety.
Downfeed Unit
Hydro-pneumatically controlled, with adjustable rapid movement downwards and return. Cutting cycle is totally controlled via bellows hydrocheck. As a safety feature, unit will not operate if electrical power is disconnected.
In upper rest position motor shuts itself off.
Control Panel
Ergonomically set for good visibility and safety. Unit must be 2 hand operated. Panic button is latching type and safety colored.
Sawblades
HSS Sawblades recommended only.
350mm (14″) maximum size suitable.
Special applications might require smaller sawblades.
