1160 machining center chip conveyor

1160 machining center chip conveyorIt is a core auxiliary equipment, whose core function is to quickly remove iron chips, aluminum chips and other chips generated during processing, avoid accumulation and scratching of the guide rail, jamming of the spindle, and recover the coolant.
The workflow of the 1160 machining center chip conveyor is synchronized with the machining process of the machine tool, requiring precise coordination with the rhythm of "chip generation collection discharge". The specific steps and key details are as follows:

1. Start and linkage control (to avoid idling or leakage)

Linkage trigger: The chip conveyor is usually linked to the machine spindle - when the spindle starts (M03/M04 instructions), the chip conveyor automatically starts; After the spindle stops (M05), the chip conveyor will stop with a delay of 30-60 seconds (to ensure the removal of residual chips) to avoid idle energy consumption or chip residue.

Manual control: The machine operation panel is equipped with a "chip conveyor start stop" button. When processing special materials (such as aluminum chips that are prone to adhesion) or when there is a large accumulation of chips, the "strong discharge mode" can be manually activated (increasing the speed to 12-15m/min).

2. Chip collection and transportation (ensuring no dead corners or stuck chips)

Chip collection: The chips of the 1160 machining center are mainly generated in the X/Y/Z axis guide rail area and the worktable. The conveyor groove of the chip conveyor needs to cover these core areas - the conveyor groove below the worktable should be aligned with the edge of the worktable (gap ≤ 5mm) to avoid chips falling into the interior of the machine tool (causing guide rail jamming); The chips on the Z-axis column side are guided to the conveyor trough through a guide plate (tilted 10-15 °) to prevent accumulation at the bottom of the column.

Delivery details:

When the scraper moves, it should be tightly attached to the bottom of the conveyor groove (gap ≤ 1mm) to ensure that small chips (such as cast iron powder) are not missed;

When encountering block shaped chips (such as chips larger than 50mm generated during steel processing), the scraper must have sufficient thrust (controlled by the torque of the reduction motor, ≥ 10N · m) to avoid chips getting stuck on the scraper;

Install a curved transition (radius ≥ 50mm) at the corner of the conveyor trough (if any) to prevent scraper jamming or chain wear.

3. Chip discharge and coolant separation (reducing resource waste)

Chip discharge: When the chips are pushed to the chip discharge port by the scraper, they fall into the chip collection box by gravity. Some models have a "chip scraper plate" at the chip discharge port (to clean the chips adhered to the scraper, such as aluminum chips), to prevent the chips from flowing back with the scraper.

Coolant separation: A filter screen (with a diameter of 2-5mm) is installed at the bottom of the conveying groove, and the coolant in the chips flows into the machine tool water tank through the filter screen (for recycling) to reduce coolant loss. When processing the 1160 model, the coolant flow rate is usually 20-30L/min. The chip conveyor needs to ensure a separation efficiency of ≥ 90% to avoid coolant being discharged with the chips (increasing costs).

4. Fault self-protection (to avoid equipment damage)

Overload protection: When the chips get stuck on the scraper (causing excessive load), the chip conveyor motor is equipped with a thermal overload protector (set current 1.5-2 times the rated current), which automatically stops after triggering and displays an "chip conveyor overload" alarm on the machine panel;

Chain breakage/scraper breakage detection: Equipped with a proximity switch, when the chain loosens or the scraper breaks, the detection signal is abnormal and the machine will immediately stop to prevent further damage to the conveyor trough.
