FAQ FRO ANGLE STRAIGHTENING MACHINE

A

1. Benefitting from top grade quality and word of mouth reputation on our machine, Wuxi JACK machines all have service life of over 10 years, under the condition of proper use and maintenance;
2. Many customers become repeat customers with time going, when they find Wuxi JACK machines have very good quality and stable running, the lowest running cost, and safe operation.

A This can be listed as:

1. Sufficient land area and workshop height, to accommodate on “huge” size of overall dimension machine frame, and height. Especially workshop ceiling height, make sure it has enough space, to install the travel crane overhead, above the 9m height DX6080 (The largest model) model, avoiding issues of conflict between travel crane and top of steel structure Large Beam End Milling Machine, caused from insufficient workshop height;
2. The traveling crane for hoisting workpieces of heavy duty models should have sufficient loading capacity, which should be at least 50 ton;
3. Prepare sufficient deep and sized foundation, to install horizontal base bed of steel structure BOX H Beam Large End Face Milling Machine.

A The overall design and manufacture on large models are completely different from conventional models, which can be summarized as below 3 major points of:

1. Mechanical Frame: The size and structure of horizontal bed, and especially upright column (The most critical main assembly of large model machine). Not only the counterpart dimension will be enlarged to original 1.5 to 2 times size, but also structure is considered to be upgraded, to maintain on sufficient strength and integrity;
2. Milling Head Power: Larger and heavier steel structure workpieces entail deeper and higher efficiency cutting depth, which, although higher power than other suppliers’ 5.5kW, the 7.5kW milling head is usually turned into 9.3kW or even 11kW milling head, made in Taiwan E-LONG;
3. Transmission along Horizontal and Vertical Direction: As the core function units on generating power on milling head movement, with increasement of stroke and workpiece size, this unit is also different from conventional models.

A

1. BOX H Beam End Face Milling Machine belongs to “Heavy milling”, or “Rough Milling”, with cutting depth of 5- 6mm every stroke. Its purpose is to remove rough surface of workpiece. This machine adopts with small milling cutter head of Φ160mm to Φ200mm, basically applied in Steel Structure industry;
2. Comparatively, Milling Machine belongs to “Fine Milling”, with cutting depth of 0.3- 0.5mm every stroke, attaining on surface finish of 3.2～6.3. It is usually equipped with Φ250mm to Φ300mm large cutter head.

A

1. People always care on machine quotation. This is natural. On the other hand, just think on 10% price difference, versus the subsequent running cost: The stable high standard performance of machine, and high efficiency, which can help customer saving time and variable cost during daily production, compared with the frequent shut down of machine, and its repair cost, caused from inferior quality of machine;
2. Generally speaking, these factors should be taken, before purchasing a set of BOX H Beam Steel Structure End Face Milling Machine:

1. The milling head, its power and performance;
2. The milling head movement guiderail;
3. Mechanical frame, its size and integrity;
4. Electric control elements, quantity of A.C. inverter
5. Supplier capability, achievement and experience

A No, if operate and maintain the CNC machine properly, under the guidance from Wuxi JACK. The design and production of Wuxi JACK CNC machine fully considers operation under challenging surroundings, and we take measures accordingly to fully protect the machine. For example:

1. The IP level of electric system: Control board/ CNC controller/ cables;
2. The protection on hydraulic system and pump station;
3. Protection on milling head/ cutter/ linear guiderail, etc.

A

1. The price of CNC machine is about 10% higher than counterpart (Refers to same stroke on horizontal and vertical end face milling) of conventional type, which mainly arises from CNC / servo driver and servo motors;
2. On the other hand, when customer need to process on irregular shape end face of workpieces, the 10% higher price will pay for within short time, benefitting from precision and productivity.

A Operator should command on the ability on operating CNC controller of the machine, including, but not limited to:

1. Being familiar with distribution of buttons/ switches/ interface ports/ function keys on the front panel of the CNC controller;
2. Call out part programs for carrying out end face milling from embedded library in CNC controller;
3. Modify on process control parameters of workpiece and operation based on practical condition, etc.
