Abstract
Method for producing a cylinder unit, with the steps: clamping the cylinder (44) to the workpiece clamping device (42) of a lathe (34), skiving the cylinder inner surface (62) of the cylinder (44) by means of a skiving tool (10), in particular by rotating the workpiece clamping device (42) such that a skived cylinder inner surface (62) is formed, smooth rolling the skived cylinder inner surface (62) by means of a smooth rolling tool (60), in particular by rotating the workpiece clamping device (42), and processing at least the front surface (64) of the cylinder unit, wherein the skiving, the smooth rolling and the processing at least of the front surface (64) are carried out in one setting.
Claims17
A method for producing a cylinder unit, comprising the steps:
- clamping a cylinder to a workpiece clamping device of a lathe,
- skiving a cylinder inner surface of the cylinder by means of a skiving tool, the step of skiving including actuating the skiving tool and rotating the workpiece clamping device, such that a skived cylinder inner surface is formed,
- smooth rolling the skived cylinder inner surface by means of a rolling tool, the step of smooth rolling including rotating the workpiece clamping device, and
- processing at least a front surface of the cylinder,
- wherein the steps of skiving, smooth rolling, and processing at least the front surface are carried out in one setting, and
- wherein the same cooling lubricant actuates the skiving tool and removes chips resulting from the step of skiving.
A method for producing a cylinder unit, comprising the steps:
- clamping a cylinder to a workpiece clamping device of a lathe;
- skiving a cylinder inner surface of the cylinder by means of a skiving tool, the step of skiving including rotating the workpiece clamping device, such that a skived cylinder inner surface is formed;
- smooth rolling the skived cylinder inner surface by means of a rolling tool, the step of smooth rolling including rotating the workpiece clamping device;
- and
- processing at least a front surface of the cylinder,
- wherein the steps of skiving, smooth rolling, and processing at least the front surface are carried out in one setting,
- wherein the step of skiving the cylinder inner surface comprises removing chips by means of a cooling lubricant, and
- wherein the cooling lubricant is released by at least one cooling lubricant nozzle and is under a pressure (pKSS) of at least 4 MPa.
A method for producing a cylinder unit, comprising the steps:
- clamping a cylinder to a workpiece clamping device of a lathe;
- skiving a cylinder inner surface of the cylinder by means of a skiving tool, the step of skiving including rotating the workpiece clamping device, such that a skived cylinder inner surface is formed;
- smooth rolling the skived cylinder inner surface by means of a rolling tool, the step of smooth rolling including rotating the workpiece clamping device;
- and
- processing at least a front surface of the cylinder,
- wherein the steps of skiving, smooth rolling, and processing at least the front surface are carried out in one setting, and
- wherein a cooling lubricant flow rate amounts to a maximum of 100 liters per minute.
A lathe, comprising
- (i) a spindle;
- (ii) a workpiece clamping device, which is driveable by the spindle and is configured to clamp a cylinder unit such that the cylinder unit can be turned about the longitudinal axis of the cylinder;
- (ii) a slide for positioning a cutting tool in a pre-determinable position relative to the workpiece clamping device, such that the face of the cylinder unit can be processed;
- (iv) a skiving tool, the skiving tool including
- at least one cooling lubricant nozzle for releasing cooling lubricant,
- at least one cooling lubricant pipe, by means of which the cooling lubricant can be taken to the cooling lubricant nozzle,
- at least two skiving blades that are mounted in a floating manner and that are moveable at least in a radial direction, and
- a steering cylinder by means of which the skiving blades are extendable and retractable,
- wherein the steering cylinder is subjectable to pressure via the cooling lubricant pipe;
- and
- (v) a smooth rolling tool for smooth rolling the cylinder inner surface, the smooth rolling tool being set up such that the cylinder inner surface of the cylinder unit can be processed by smooth rolling.
