BORING-ROLLING MACHINE MAR 60-250 x 9000

Chapter 1. INTRODUCTION

This Instruction Manual is intended to make you familiar with the mounting, commissioning and operation of the boring-rolling machine MAR 60-250 mm x 9000mm.
Knowing the components of the machine and how it works is very important for the purpose of commissioning and efficient exploitation.
By following the instructions in this manual, you will be able to prevent malfunctions and the technological process will be carried out in optimal conditions, ensuring a superior quality of the machining.
Prior to commissioning of the MAR 60-250x9000, a careful consideration of all the control elements is required.

Chapter 2. OPERATING CONDITIONS

The boring-rolling machine MAR 60-250x9000 is designed to operate in a temperate climate zone, in closed spaces like industrial halls.
The operating conditions are as follows:

- ambient temperature during:
- use : + 5°C...+35°C ;
- transport : - 25°C ... +55°C ;
- storage :- 25°C... +55°C , according STAS 8138-
83(EN60204);
- maximum altitude 1200 m ;

- relative monthly average humidity, reported to 20°C, should not exceed 80%, according EN 60204 ;

- penetration degree of foreign bodies and water , IP 54 , according EN 60529

Chapter 3. TECHNICAL DESCRIPTION OF THE MACHINE

Boring and superfinishing machine by rolling tubes, MAR 60-250x9000, is specially designed for internal processing of tubes using a combined tool that performs the boring-rolling operation.
Boring-rolling machine for hydraulic cylinders, MAR 60-250x9000, can process through boring-rolling method, internal diameters from 60 mm to 250 mm over a length of 4000 to 9000 mm.
Boring-rolling machine for hydraulic cylinders, MAR 60-250x9000 has a flatness of 0.02mm/1000mm in the transversal and longitudinal direction, of 0.03mm/1000mm, quotas made between the extreme centers (gearbox, rear windows, adduction head, vice and rear locking head).
The radial race of the gearbox shaft is 0.03mm/1000mm according to the quality standards for these machines.
Advancing work horizontally has a very high precision, rigidity, it is silent, due to the double reducers existing in the two sledges - gearbox, adduction head - as well as the two racks disposed on both sides of the machine guides.
The silence of the gearbox is also due to the fact that the transmission and the variation of the number of rotations/ minute are made electronically which does not affect the cutting force.

Chapter 4. MACHINE FUNCTIONING

Performing a processing on the rolling-boring machine includes the following technological operations:
- connection to the electrical grid via the switch placed on the electric control panel
- mounting on the machine the accessories required for machining (head adduction bushings, rear locking head bushings, toolholder shaft rear windows bushings, toolholder shaft, prisms and parallel plane parts corresponding to the diameters to be machined according the attached table, combined tool, indexing)
- withdrawing the tool in its original position of „0"(zero)
- this quota is set on touch-screen
- feeding with semi-finished product the pneumatic clamping and locking system with the aid of the feed and transfer mechanism
- driving the rear locking head until it it sealed with the bush from the adduction head
- must be set the quota of clamping and releasing the tool (the length of the workpiece + quota of releasing the boring box and driving the rolling box)
- the cooling and evacuation pump is connected
- setting the working mode on the touch screen
- engaging the toolholder shaft
- the work advance is set
- after the tool reaches the established longitudinal machining quota, the tool is indexed and the work advance is connected - the boring tool is disarmed and the rolling tool is armed helped by the pneumatic indexer
When the tool reaches the "0" position (zero), the machine stops automatically
- the cooling system stops
- the rear locking head is unlocked, the adduction head on a safety distance to measure the achieved quota.
- the vices are unlocked
- the transfer mechanism that transfers and unloads the piece onto the storage table is activated, it returns to its original position and feeds the machine with another piece
During processing, the operator checks the previously machined finite piece, both dimensionally and roughly at both ends, inside and over the entire length, in order to detect possible scratches.
WARNING!!!
At the beginning of the shift, the oil tanks of the sledges which move the toolholder shaft rear windows must be refilled, the oil level from the lubrication system of the gearbox sledges, rear locking head, sledge reducers, adduction head and gearboxes, must be also checked and filled
