CROZIER SPEED LATHE - Model 30DC3/4 HP Belt Drive, 0-3600 RPM, Variable SpeedThe Crozier Model 30DC Speed Lathe is our most popular model. It has many standard features not found on any other machine in its class or price range.
Description:Air-Collet Closure: The air-collet closure is designed and built as an integral element of the speed lathe. Therefore, low speed restriction or cylinder wobble is NOT inherent in Crozier speed lathes. The foot switch operated air-collet also mitigates operator fatigue in achieving collet closure. A foot valve operates the collet closure leaving both hands free. The air-collet closure facilitates rapid loading and unloading of the part. For thin wall parts, an air regulator on the inlet air will reduce the pressure to prevent damaging delicate parts. For Inside Dimension (ID) collets, the collet closure provides more than enough movement to properly operate the collet. Variable Drive motor: The DC variable speed motor provides spindle speeds from 0 to 3600 RPM. This wide range allows the operator to find the optimum speed for each operation. There is no need to move the belt to change the speed. The motor is rated at 3/4 horsepower, sufficient for demanding jobs. The motor transfer is through a multi-groove belt, similar to the belt under the hood of your car. Dynamic spindle braking is provided through the control. There is nothing mechanical in the braking mechanism to wear, replace or adjust. Spindle: The oversized spindle rides on ball bearings. The machine can operate continuously at 3600 RPM. The front bearing, on the collet end, is a double row assembly with an extremely high load capability. The bearings are permanently lubricated. The spindle has a through hole up to the capacity of a standard 5C collet. The collet insert can be replaced without replacing the entire spindle. Power: The Speed Lathe requires 120 Volts, single-phase power. The input power is AC that is converted to DC. By design, the DC motor only draws power as required for the operation. Air requirements are 90 PSI dry air. Specifications:
